Abstract

Antiperspirant products comprise a dispensing container for a soft solid having a narrow aperture through which its contents can be dispensed. The contents comprise a particulate antiperspirant active suspended in a water immiscible liquid which has a refractive index that differs from that of the antiperspirant active by preferably not more than 0.08. By controlling the liquid and solid phase refractive indexes to within such a difference, it is possible to dispense a ribbon of soft solid through the narrow aperture which has a translucent appearance, even if the gross formulation within the dispenser is opaque. Particularly desirably, the refractive indexes differ by at least 0.01 or 0.02 to 0.06, in order to additionally avoid formulation constraints that would apply in respect if the liquid and suspended active had to be exactly matched.

Description

The present attention caters to such soft solid positions. Such compositions have sufficient rigidity that they are not observed to flow through the human eye, but are deformable by hand pressure and can be extruded from a container through one or more openings at the end of the container. To use a small amount of the composition is extruded from the container, which can then be used as an applicator to spread the extruded material on the skin. • A variety of properties of such com positions are significant. The composition should be stable and not escape from its container until it is extruded deliberately. Your sensory perception when applied should be, in a desirable way, not sticky. The applied film of the preferred position is from ^ a translucent or translucent appearance in an opaque white. 1 $ This property is referred to as low visible residue, and it is desirable in order that the deposit on the user's skin is not easily seen. Moreover, this avoids striking marks on clothing, to which the deposited material can be accidentally transferred. There have been proposals to form other forms of antiperspirant product 20 in order to be transparent. This is attractive for the • consumer, but it is difficult to achieve. What is required is that the refractive indices of the ingredients of the composition should be closely matched, usually by less than 0.003. This is difficult to achieve and imposes constraints on the formulation, 25 which are detrimental for other properties perceived by the In a specific way, some transparent bars that have been marketed are solidified solutions with a sticky sensation, which is a very strong organic polar solvent. It is also known to make transparent products. which sfffí i emulsions with closely matched refractive indices of the two phases are commonly described as transparent gels, and often do not contain a structuring They are perceived by users as excessively wet and tend to suffer a localized loss of clarity after the package has been open and used, as a result of loss of volatiles from the rest unused, < So the unfinished product seems to have deteriorated. There have been suggestions in the literature that a refraction index refraction as large as 002 will not destroy transparency. We have now found that compositions according to this teaching do not seem transparent.

BRIEF DESCRIPTION OF THE INVENTION We have now found that by some control of the formulation of a soft solid, which is a suspension of active antiperspirant particulate together with an appropriate package (which may be variations of a type currently in use for solid antiperspirant compositions). soft opaque), it is possible to create a product where the material dispensed has an attractive translucent appearance before application on the skin If the replicate has openings Rare extrusion of the composition, tees X > which are small in cross section, ie, sufficiently narrow in at least one dimension, the extruded composition may have an attractive translucent appearance, since the refractive index of the liquid in the composition does not differ from that of the anlitranspirant active. for more than a limited amount, possibly around 010, and preferably for no more than about 008 or 007 The translucent appearance provides an indication to the consumer 0 that the deposit of the composition on the skin (or accidental deposit on the clothing) will be transparent or have low visibility There is no need to use antiperspirant active of exceptionally minute particle size (ie, nanometer scale), Accordingly, in a first aspect, this invention provides an antiperspirant product comprising (i) a dispensing container provided with one or more outlet openings for a user to expel material from the patient. container through said or said outlet openings, and (n) within said dispensing container, a mild solid antiperspirant composition Q comprising a continuous phase of water immiscible liquid, at least one structuring material which thickens said liquid, and a active antiperspirant particulate in suspension in said liquid, wherein the refractive indexes of said antiperspirant active and said liquid differ by no more than about 007 The water immiscible liquid will generally be a mixture of and the refractive index of that mixture should not differ by more than 0.07 from that of the active antiperspirant or active mixture. It is anticipated that the refractive indexes will usually differ by at least 0.01 or 0.02 - avoiding the most difficult constipation in the formulation necessary to achieve a closer match Preferably, the difference will not exceed approximately 0.06. Structuring materials can come from several categories. Its purpose is to increase the viscosity of the water-immiscible liquid thus the entire composition, so that in the container before extrusion at the time of use it is a soft solid. A class of materials, which have traditionally been used as structuring agents, are fatty alcohols, which are solids at 20 ° C. These are not preferred for this invention because they give an opaque white appearance with a high visible residue. A category of materials that can be used are waxes, which are solid at temperatures above at least 30 ° C, although they generally melt at a temperature not higher than 95 ° C. An amount of 3% or 4% up to 8% by weight of the composition may be adequate. A further and preferred possibility is an organic polymeric thickener, which is effective to increase the viscosity of the water immiscible liquid. If used alone, the amount of such a polymer is likely to be 3% or better 5% up to 20% by weight of the composition. According to a co-pending request, another preferred structuring system is a combination of such organic polymer, together with a second structuring material selected from a) structuring, which forms an r & t fibers derltro of the continuous phase b) waxes, other than fatty alcohols, which are solid at 5 temperatures of 30 ° C and below, but melt below 95 ° C, and c) mixtures thereof in such system , the amount of polymeric thickener is preferably based on a range from 15% to 15% by weight of the # composition If the structuring (a) is present, which forms a network ) 0 of fibers within the continuous phase, the amount of this will generally be from 05 or 1% up to 7% by weight of the composition If the wax (b) is present, the amount of it will generally be from 05 or 1% up 15% by weight of the composition More preferably, the total amount of a F second structuring material can be from 1% to 7% by weight of The composition and total of organic polymer and second structuring material can be from 3% or 4% to 10% or 12% by weight of the composition. Among the various possibilities above, it is preferred to use a polymeric thickener, alone or in conjunction with a second material 20 Structuring If the structurant includes polymer or not, the structurants F fiber formers are sometimes preferred over those waxes, which do not form fibers, and on other occasions they prefer the use of non-fiber-forming waxes. In many cases, the total amount of the po mépco thickener 25 organic and the second structuring material will be greater than the amount total of any fatty alcohol, which is solid at 20 ° C. There is no need to incorporate any type of fatty alcohol. Preferably, fatty alcohol is excluded only at low concentrations, such as no more than 3% in of the composition, better 5 no more than 1 5% because it is known that qt! é crystallizes as relatively large platelets and increases the opacity and visibility of fos deposits As mentioned, the container should have a provision for m that a user eject material through the outlet openings A container will generally have a part of the body sized to be held in the hand and the outlet opening (s) at one end Means to urge the contents of the container to said opening or openings, so that flow through them can move parts operable by the user or can simply be container walls 15 flexible, so that the user can expel composition from the container by tightening it A container shape has a barrel or tube to hold an amount of the composition and a component part referred to as an elevator or piston, which is capable of movement within of the barrel or tube 20 for driving the composition toward the outlet opening (s). Preferably, the container also includes a transport mechanism for moving the piston comprising a threaded rod, which extends axially towards the body of the composition. through a correspondingly threaded opening in the piston, and 25 means for relatively rotating the rod and the piston Conveniently, this is a mechanism or operable wheel to &&f "such as a handwheel or ratchet and fingernail) located at the opposite end of the container to the delivery opening.The outlet openings are normally formed in a closure for the container.The openings should each be so that the material extruded through it is not more than 0.5 cm thick in at least one dimension, in this way, an opening could have a cross section with its smallest dimension smaller than 0.5 cm in width, a rectangle of 0.4 cm by 0.8 cm it would be an example, the material extruded through it would be a strip 0.4 cm thick Possibly, each opening will have a cross section which is no more than 0.5 cm in any dimension A circular hole of 0.5 cm diameter would be an example, subject to the above requirements, the number and design of such openings is at the discretion of the package designer. Similarly, the distribution of such openings in the head dispenser of the container is at the discretion of the package designer In practice, the openings are often circular or oval or parallel side slots, the slots being straight, curved or serpentine-like, frequently having rounded ends, or a combination of two or More designs The variety of openings is frequently from 5 to 150, especially 8 to 120. The openings are often arranged in a symmetrical manner in the dispensing head, such as parallel grooves, or in a radial design centered on the container shaft, or a rectangular arrangement of circular openings u ovals, or in concentric or intersecting circles, The component parts of such containers are often made of thermoplastic materials, for example, polypropylene or polyethylene. Descriptions of suitable containers, some of which include additional features, are found in US Patents 4865231, 5000356 and 5573341 and WO 99/29585. Compositions with preferred structurants (ie, polymer or a combination including polymer) are simple of • manufacturing. The compositions can be made and packaged by heating their constituents to form a liquid composition, mixing at temperatures where the composition moves freely, placing the composition in retail containers and cooling or allowing these compositions to cool to room temperature. -f A method is provided for preventing or reducing transpiration in human skin, which normally comprises applying to the skin a composition as specified in the first aspect of this invention.

Fig. 6 is an enlarged end view, in the direction of arrow VI in Fig. 5, with the removable lid removed to show the outlet openings. Fig. 7 is a diagrammatic cross-sectional view of a third form of dispensing container, with its upper part in section. Fig. 8 is an enlarged top view of the container of Fig.7. r 'DETAILED DESCRIPTION AND MODALITIES 10 Dispensing Containers A first example of a dispensing container is shown in Figs. 1 to 3 of the drawings. This container has a removable lid 3, which is removable and replaceable by the user. The container has a F? barrel 5 of oval cross section. The upper end of the barrel is secured by click adjustment (indicated at 8 in Fig. 2) to an upper portion 10. Snapped into an upper opening in the upper portion 10 is an insert 6, which defines the outlet openings 7. The lower end of the barrel 5 is closed by a base plate 20 12. - The lid 1 with a bulged shape 3 is transparent, so that the openings 7 of the insert 6 are visible. The inner surface of the lid 3 is provided with stops 4 which serve to maintain a head space between the lid 3 and the upper portion 10. The base plate 12 provides a 25 Mounting for a knurled hand wheel 13 attached to a threaded spindle 14. This, as shown in Fig. 2, extends into the barrel 5 and engages a threaded central opening in up lift piston 15 inside the barrel 5. By turning the hand wheel 13 with the fingers, the user can lift the piston 15 inside the barrel 5 to push the composition, contained in the barrel above the riser piston 15 towards the outlet openings 7. The composition is then expelled through the openings 7. In this way, the user can dispense the composition-from the container through the outlet opening 7 as required. The outlet openings 7 are curved grooves each having a uniform width, as indicated for example, between the arrows (A), which is approximately 2 mm The composition is expelled accordingly, from the container as a plurality of slats each approximately 2 mm thick. Before the container is filled, the lifting piston 15 is positioned at the bottom of the container and the insert 6 is not adjusted, thus leaving a fairly large opening in the upper part of the container through which molten composition can be emptied, in the upper part of the piston 15. After the container is filled, the insert 6 is clicked into the opening in the upper portion 10, the lid 3 is adjusted and the filled container is ready for retail sale. If desired, an adhesive label can be secured on the insert 6 by closing the openings 7, until this adhesive label is torn by the user before the first use Fig. 4 shows a minor modification Instead of the plurality of slots 7 in insert 6, there is a single central hole 18- with a diameter of 4 mm. In a location of Fig. 4, not shown, he only centff hole! is an arrangement between between and 130 holes, for example, 120 5 holes, each with a diameter between 1 and 3 mm. Fig. 5 and Fig. 6 show a second example of a dispensing container, which is described and illustrated in greater detail in PCT publication WO 99/29585. This container has a main body 22 with a first end 10 closed, rounded 24 and a second end 26. The second end 26 has an open mouth 28. The container also includes a closure 32 with an oval end face 34 and a surrounding flange 36. When the closure 32 is adjusted to the end 26 of the main body 22, a short inner wall 38 in the closure snaps into the mouth 28 of the main container 15 22. A removable lid 40 fits over the closure 32 and a final portion of the main body 22. This lid 40 can be removed and replaced by the user. As shown in Fig. 6, the face 34 of the closure 32 has three outlet openings 42 in a generally central position. The main body 22 is relatively rigid in the region of its? Rounded, closed end 24, but an average area of the walls of this container body is relatively flexible to allow it to be squeezed by the user. When the body of the container is squeezed? this way, its contents are propelled towards the mouth 28 and a portion is extruded through the outlet openings 42. Each of this? openings of saitda is a slot e? corvada cdn u n wide, | .nd? ca l 1 for example between the arrows (A), of approximately 1 mm. Consequently, when the user squeezes the container body 22, material is extruded from it as three strips, each one or 1 * m rn d§ 5 thickness This container is intended to be rested on the removable lid 40 and with the container mouth 28 downwards. For this reason, the container lid 40 incorporates plugs 46 to fit in, and therefore block, the salt openings 42 The container of Figs. 5 and 6 is filled with a molten composition upon emptying that composition through the mouth 28 After this, the closure 32 is fitted on the end 26 of the body of reci pient and, as mentioned, the inner wall 38 within the closure 32 is adjusted for click on the mouth 28 of the container body 22, so that it is 15 held in place Fittings 7 and 8 diagrammatically illustrate a third example of a dispensing container This is currently in commercial use for opaque soft solid compositions This container has a tapered downwardly tapered main body 50 of generally 20 ova l, on which it is adjusted by clicking or closing 52 Mounted • rotatably within the main body 50 is a tube 54 of integral circular cross-section with an operable wheel of the ppr user 56, exposed at the base of the body 50. A threaded spindle 60 is centrally accommodated within the tube 54 The top of this The spindle 60 is coupled to a sleeve 62 of the end cap 52 and thereby - it prevents it from rotating A piston has a threaded central opening •• that engages the thread of the spindle 60 The tabfiniffer 52 incorporates a dependent flange 66 that surrounds the upper part of the tube 54 The upper cover 52 has eight openings 68 , each of which 5 is a groove with a width, as shown by arrows (A), 3 mm and a length of approximately 12 mm Adjacent to one edge d @ each opening 68, there is a blade 70 which is projected downwards and is also somewhat inclined As a result, if the container is empty, the blades 70 are visible through the openings 68 as seen in Fig 8 These containers are filled with the piston 64 in its position lowermost and before the closure 52 is adjusted The molten composition is emptied into the central tube 54 at the top of the riser piston 64 F The space between the tube 54 and the body 50 remains empty The upper closure 15 is then snapped onto the body 50 and its sleeve 62 is coupled to the upper part of the spindle 60 For use, the user turns the hand wheel 56 and in doing so, rotates the central tube 54 and the composition within it in relation to the body 50 , A fingernail, not shown, constricts the direction of rotation? L piston 20 riser 64 frictionally engages tube 54 and rotates together with and with the F composition just on the However, because the central spindle 60 does not rotate, the lift piston 64 moves the spindle 60 upwards, thereby pushing the composition up towards the outlet openings 68 As the user rotates the wheel 56, the inclined blades 70 are 25 raise from the top of the composition in tube 54 and from there, they help to guide the flow of the composition up to and through the outlet openings 68 A removable and replaceable transparent lid, not shown, is also provided by being placed over the closure 52 and the upper portion of the body 50 It should be understood that these three embodiments of the dispensing container have been illustrated and described by way of example only, and serve to show the diversity of details between the dispensing containers, which can be used with 10 compositions for giving products of the present invention COMPOSITIONS The various materials that may be present in a F composition of this invention will now be described in turn and 15 will indicate the characteristics and preferred possibilities Immiscible liquid in water Immiscible liquid in water comprises one or a mixture of materials, which are relatively hydrophobic in order to be 20 immiscible in water Some hydrophilic liquid can always be included • that the overall liquid mixture is immiscible with water.

K 2 Zí exceeds 15% by weight; • Structured liquids are obtainable by cooling, from a high temperature at which the structurant is in solution in the liquid - this hot and mobile solution is available; • the structured liquid (thus obtained) becomes more mobile if it is subjected to a cut or tension; • the structure does not recover spontaneously cut liquid is left to be treated at tetnperatu? la * fN é * fen, f © -. laboratorib, even though a small partial recovery can be observed; • The structure can be recovered by reheating at a temperature at which the structurant is in solution in the liquid, and allowing it to cool to room temperature in the laboratory. It seems that such structurants operate through interactions, which are permanent unless they are broken by cutting or heating. Such structurants form a network of filaments or fibers that extend through the gelled liquid. In some cases, these fibers can be observed by electron microscopy, although in other cases the observation of the fibers, which are believed to be present, is avoided by practical difficulties when preparing a suitable specimen. When observed, the primary fibers in a gel are generally thin (diameter less than 0.5 μm, often less than 0.2 μm) and appear to have numerous branches or interconnections. The primary fibers can be entangled to form a thicker filament. If these fibers are crystalline, they may or may not be the same polymorphic as macroscopic crystals obtained by conventional crystallization from a solvent. A material that is well known for forming such gels, is 12-h? Drox acid? stearic, which is discussed in Terech et al. "Organogels and Aerogets of Racemic and Chiral 12- hydroxy octadecanoic Acid" (Organogels and 12-hydroxy acid aerogels octao) racological and chiral ekanoic), Langmuir v * oi 1b,! 406, -3418, 1994 The ufe matepal is commercially available from m M * oto and also from Caschem US-A-575 * 0096 is one of Several documents show that the gelation can be originated by using a ferric oxide or amides of 12-hydroxy stearic acid. The alcohol used to form such an ester or the amide used to form such an amide can contain an aliphatic cycloalphatic or aromatic group, with up to 22 carbons therein If the group is aliphatic, preferably it contains at least three carbon atoms A cyclic histatic group preferably contains at least five carbon atoms and can be a fixed ring system, such as adamantyl Other acids fatty acids with C8 alkyl chains or longer, can be used and amides can also be used. A specific example is laupca monoethanolamide also called MEA lauramide. The amides and esters of N-acyl amino acid are also known as structure fluids We have established that they do so by forming fibrous networks. They are described in US patent 3969087. N-lauroyl-L-glutamic acid di-n-butylamide is commercially available from Ajinomoto under its designation GP-1 Additional materials, which have been described as gelling agents, are the amide derivatives of di- and tribasic carboxylic acids disclosed in WO 98/27954 notably alkyl N N'dialqul succinamides »A structurant which is the subject of a co-pending application, published as WO 00/61096, is a combination of a sterol and a sterol ester In its preferred form, the sterol satisfies either of the two formulas wherein R represents an aliphatic, cycloaliphatic or aromatic group, and preferably an aliphatic, saturated or unsaturated, linear or branched hydrocarbon group R desirably contains from 1 to 20 carbons, and preferably from 4 to 14 carbons 20 It is particularly suitable to employ β-sitosterol or campesterof or cholesterol, or a hydrogenated derivative thereof, such as dihydrocholesterol, or a mixture of two or more of Nos A particularly preferred sterol is β-sitoesterol The preferred sterol ester is opzanoi, sometimes referred to 25 as? -opzanol, which contains material that satisfies the following formula The sterol and sterol ester are used in a molar ratio which is normally selected in the range from 10 1 to 1 10, especially from 61 to 1 4, and preferably in the range from 31 to 1 2 The use of the two constituents of the system within such a molar ratio range, and especially within the preferred range, facilitates the co-stacking of the constituents accordingly, facilitates the formation of a network that is easily able to structure the formulation. Another structuring, which is the subject of a co-pending application published as WO 00/61079 and which may be used in this invention, , is an ester of cellobiose and a fatty acid, preferably of 6 to 13 carbon atoms, especially 8 to 10 carbon atoms Preferably, the cellobiose is completely or almost completely estepficated, and is in the anomeopic form The structure of such a compound, in its a-anomeopic form is where R is an alkyl or alkenyl chain of 5 to 12 carbon atoms, so that the acyl group contains 6 to 13 carbon atoms Particularly preferred acyl groups incorporate a linear alkyl chain of 7 to 9 carbon atoms and thus are octanoyl, nonanoyl or decanoyl. Acyl groups may have a mixture of chain lengths, but it is preferred that they be similar in size and structure. Thus, it is preferred that all acyl groups are aliphatic and at least 90% of the acyl groups have a chain length within a range, so that the shorter and longer chain lengths in the range differ by no more of two carbon atoms, that is, the length in a range from m - 1 to m + 1 carbon atoms where m has a value in a range of 7 to 10 The linear aliphatic acyl groups can be obtained from natural sources, in which case the number of carbon atoms in the acyl group will probably be an even number or it can be synthetically derived from petroleum as the raw material, in which case string lengths of even and odd numbers are available. Synthetic methods for estepfication of sacapdos are well known The stepofication of cellobiose has been reported by Takada et al. al in Liq id Crystals (1995) Volume 19, pages 441-448 This article gives a procedure for the production of the alpha anomics of cellobiose octa-alkanoates by means of this ß-i cellobiose using an alkanoic acid together with trifluoroacetic anhydride An additional class of fiber-forming structures, which are described in a co-pending application, satisfy the general formula rnß in which R and R 'are each independently a linear or branched portion containing 5 to 27 carbons, m and n are each independently 0 or 1, and Y is a cyclohexane ring bearing the two amido substituents shown above Preferably, R and R 'are selected from C11 to C17.

Waxes are usually hydrocarbons, polymers of fatty acid esters or mixtures containing such compounds together with a minority (less 50%) of other compounds Naturally occurring waxes are often mixtures of compounds, which include a substantial proportion that is probably a majority of fatty esters. Waxes form crystals in the water-immiscible liquid, when the state is cooled heated during processing These crystals take various forms including needles and platelets depending on the individual waxes Some waxes form a network of fibrous crystals and p therefore, fiber-forming structurants can also be identified Examples of hydrocarbon waxes include paraffin wax, microcpstalin wax and polyethylenes with molecular weight from 2,000 to 10,000 Examples of ester waxes include esters of C 16 -C 22 fatty acids with glycerol or ethylene glycol and these can be made synthetically.

Waxes useful in the present invention will generally be found to thicken immiscible oils in water , such as • f cyclomethicones, when they are dissolved in them (by heating and cooling) at a concentration of 5 to 15% by weight. If a wax is used, which forms a network of fibers, the amount of it can be from 05 to 7. % by weight of the composition If a wax is used, which does not form such a network, for example, a wax that crystallizes As, spherulitic needles or corundum peaueñas platelets, the amount hmh «can be from 2% or $% up to 10%, 12% or 15% of the composition L Silicone waxes are an example of waxes, which crystallize how small platelets 5 The total amount of second structuring can vary from 05% or 1% of the composition up to 9%, 10% or 15% The proportion of polymer to second structuring can vary considerably, but in many cases, it will fall in a range from 61 F up to 1 4 10 In a variety of modalities, the composition will contain 05 to 10% or 15% of polymeric thickener, 05 to 7% of fiber-forming structure and 2% to 10% of a wax, such as Sihcon wax, which does not crystallize as a network of fibers, all these percentages being by weight # * 'of composition 15 In other embodiments, the composition contains from 5 to 15% by weight and preferably 8 to 12% by weight of a mixture of an organic wax and a silicone wax, particularly in a proportion by weight of 51 up to 2 1 20 Antiperspirant Assets The composition will contain a particulate antiperspirant active. Antiperspirant actives are preferably incorporated in an amount from 05-60%, in particular from 5 to 30% or 40%, and especially from 5 or 10% up to 30 or 35% by weight of the composition 25 The antiperspirant active for use in the present, frequently they are selected from salts of active, astringent, insoluble, mixed aluminum, magnesium and zirconium salts, including both inorganic salts, salts with organic anions and complexes. Preferred astringent salts include halide * salts and 5-halohydrates, such as chlorohydrates, aluminum, zirconium and aluminum / zirconium. Aluminum halohydrates are usually defined by the general formula AI2 (OH) xQy.wH2O, in which Q represents chlorine, bromine or iodot x is variable from 2 to 5 and x + y = 6, while wH20 represents one. 10 variable amount of hydration.

In > some highly desirable embodiments of the present invention, the Active antiperspirant is made by an improvement to the process described in EP-A-6739. The improved process maintains a concentration of aluminum diluted during the formation of the aluminum chlorohydrate species, and closely controls the aging step, in particular aging at an elevated temperature and during a period of adequate aging in inverse relationship to one another. f Zirconium assets can usually be represented by the • "empirical general formula: ZrO (OH) 2n.nzBz.wH20, in which z is a variable in the range from 0.9 to 2.0, so that the value 2n-nz is zero or positive, n is the valence of B and B is selected from the group that 25 consists of chloride, another halide, sulfamate, sulfate and mixtures of The hydration possible to a variable degree is represented by wH2O It is preferable that B represents chloride and the variable z falls in the rang from 1 5 to 1 87 In practice, such as zirconium salts are not usually employed by themselves, but as a component of a combination aluminum and zirconium based antiperspirant i The above aluminum and zirconium salts can have coordinated and / or bound water in various amounts and / or can be pr senles as polymeric species, mixtures or complexes In particular, the salts of zirconium hydroxy frequently represent a range of salts having vain amounts of the hydroxy group Zirconium aluminum chlorohydrate may be particularly preferred Antiperspirant complexes based on the above-mentioned astringent aluminum and / or zirconium salts may be employed The complex frequently employs a compound with a carboxylate group, and advantageously this is an amino acid Examples of suitable amino acids include dl-tpptophan, dl-phenylalanine, dl-valine, dl-methionine and -alanine, and preferably glycine, which has the formula CH2 (NH2) COOH It is highly desirable in some formulations, employing complexes of a combination of aluminum halohydrates and zirconium chlorohydrates together with amino acids, such as glycine, which are described in US-A-3792068 (Luedders et al). Certain of these Al / Zr complexes are commonly called ZAG. in the literature ZAG assets generally contain aluminum, zirconium and chloride with a proportion of AL7Zr in a range from 2 to 10, especially 2 to 6 a ratio of AI / CI from 2 1 to 09 and a variable amount of glycine. of this preferred type are available from Westwood, Summit and Reheis. The water content of hydratable aluminum / alumium / circoium antiperspirant active materials can be controlled to assess the properties of the material, such as by controlling the conditions under which the material is recovered from its preparatory and dry mix, and / or by post-faction contact with a selected amount of water. In many actives, the proportion of water in the active will be chosen within the range from 6 to 18% by weight, and sometimes, in a manner • advantageous, from 11 to 18% weight 10 Other active ingredients, which may be used include astringent titanium salts, for example, those described in GB 2299506A The proportion of solid antiperspirant salt in a composition, usually includes the weight of any water in the composition. hydration and any complexing agent, which may also be present in the 15 solid active The particle size of the antiperspirant salts frequently falls within the range of 01 to 200 μm with an average particle size frequently of 3 to 20 μm. Both larger and smaller average particle sizes can also be F 20 contemplated, such as from 20 to 50 μm or 0 1 to 1 μm Antiperspirant actives, which have substantial internal voids are not avoided, preferably, because they do not have uniform refractive index Such actives can be made more useful for This invention by grinding Various grinding techniques can be employed, such as 25 as ball milling or oscillating Index values of refffa ^ tPn The particulate antiperspirant actives often have a refractive index substantially above 1 50, for example, about 1 53 to about 1 56 That value may be brought down to a somewhat lower value by hydration , but we have found that it is not easy to obtain an antiperspirant active with a refractive index of 1 48 or below, even if the active is partially hydrated to lower its refractive index. The refractive index of a solid antiperspirant active can be determined. when dispersed in a variety of oils or mixtures of oils of different refractive index When the resulting dipsersion is transparent, the refractive index of the oil or mixture of oils (which can be determined by a conventional measurement), is a good approximation to the refractive index of the antiperspirant active 15 dispersed Some examples of ace which can be used to make mixtures, which vary in refractive index and are used for the purpose of such measurement are volatile silicone (refractive index of about 1 40) 20 C12 alkyl benzoate (refractive index of about 1 48), which is available as Fmsolv TN and / or octylmethoxycinnamate (refractive index of about 1 54), which is available as Parsol MCX Polyphenylsiloxane (DC / 10) (refractive index approximately 25 1 53) cinnamic aldehyde (refractive index of approx. Siß.ß |): Provide a water-immiscible liquid with a refractive index of no more than 0.10 units beyond that of the antiperspirant active, usually involuntarily choosing an oil or mixture of oils with a refractive index of 0.10 units, preferably not more than 0.08 units below the appropriate antiperspirant. For this reason, it may be preferred that the liquid immiscible in water have a refractive index of at least 1.43, more preferably at least 1.46. 10 For the continuous phase, silicone-free, water-immiscible liquid oils generally have refractive indexes in a range of 1.43 to 1.49 to 22 ° C and can be used alone or mixed to give a silicon-free carrier liquid with an index of refraction in this range. The volatile silicone oils generally have a Refractive Index 15 slightly below 1.40 at 22 ° C, but blends of carrier liquids with refractive indexes in the range from 1 41 to 1.49 can be obtained by mixing limited amounts of silicone. Volatile with other oils. Cosmetically acceptable non-volatile silicone oils generally have refractive indexes ranging from 20 1.45 to 1.48 to 22 ° C and in this way can be included when desired. It may be desirable that the structuring materials also have refractive index that differs from those of the immiscible liquid in water and the antiperspirant active by not more than 010 or 0.08 units, 25 although it is less critical. A variety of structuring materials that refraction index of the structuring. The oils or mixtures of oils should be chosen from those that are gelled well by the structurant to avoid interference effects.

Preparation The compositions of this invention can be produced by conventional processes to make suspension solids or soft solids. Such processes involve forming a heated mixture of the composition at a temperature, which is sufficiently high so as to dissolve the entire structurant, introduce that mixture into a mold, which can be a dispensing vessel, and then allow 10 let the mixture cool. If necessary, especially if the structurant does not include organic polymer, the composition may be subjected to shear mixing before it is placed in the mold. A convenient process sequence for a composition, which is a suspension, comprises first forming a solution of the 15 polymer and another structuring agent in the liquid or liquid mixture immiscible in water. This is usually done by stirring the mixture at a sufficiently high temperature so that all of the structurant dissolves (the dissolution temperature), such as a temperature in a range of 50 to 150 ° C. Subsequently, the particulate constituent, for example, active 20 particulate antiperspirant, mix with the hot mixture. This must be done slowly, or the particulate solid must be preheated, in order to avoid premature gelling. The resulting mixture is then introduced into a dispensing vessel, such as a barrel bar. This is usually done at a temperature of 5 to 30 ° C. above the 25 solidification temperature of the composition The container and contents they are then cooled ß room temperature Cooling can be caused by nothing more than allowing the container and its contents to cool. Cooling can be aided by blowing ambient or even refrigerated air over the containers and their contents. It is highly desirable to control the process of manufacturing with the fm to prevent the excessive entrapment of gas in the formulation, commonly in the form of small bubbles and their retention in the packed formulation. By doing this, the homogeneity of the formulation f is improved and the deterioration of the clarity of the formulation is diminished or 10 even avoided The degree of entrapment of gas can be avoided or at least kept to a minimum by adequately controlling the speed and manner of mixing the formulation, while it is in the liquid or liquefied state, and / or by using a partial vacuum for above the formulation, according to the known practice Similarly, the retention of 15 bubbles in the formulation after filling in containers, can be minimized or avoided by proper control of the filling process, such as by locating a filling outlet in the stirring or storage vessel for the remote formulation from where the bubbles tend to migrate, that is, remove from the upper volume of the 20 formulation 'f Measurement of properties i) Texture analyzer This test apparatus can move a blunt probe in or out of 25 a sample at a controlled rate and at the same time measure the force * applied The parameter, which is determined as hardness, is a function of force and e | projected area of indentation A specific test protocol uses a texture analyzer Stable Micro Systems TA XT2? A composition sample was made by heating the ingredients, emptying into a container and allowing it to cool as described above. The container was a 15 ml glass jar with a wide mouth. A metal sphere, 95 mm in diameter was attached to the bottom side of the 5 kg load cell of the texture analyzer of F-WWW way that could be used to measure a sample placed below 10 of it on the base plate of the instrument After the sample was post-processed, the position of the sphere was adjusted until it was adjusted above the surface of the sample. The Texture Expert Exceed ™ computer program used to generate the subsequent movement profile used in the test method This profile moved the sphere micially 15 in contact with the sample and then indent the sphere in the sample at an indentation speed of 005 mm / s for a distance of 7 mm At this distance, the direction of movement of the sphere was immediately reversed to remove the sphere from the shows at the same speed of 005 mm / s During the course of the test the acquired data were 20 time (s), distance (mm) and force (N) and the data acquisition rate was 25 Hz. The data associated with each test was manipulated using the standard unfolded sheet computer program and used to calculate the hardness, H at a traveled distance of 476 mm after contact 25 initial with the sample, using the following equation where F is the load in the same distance traveled and Á is the projected apse * »of the indentation This arla can be calculated geometrically and is equal to the area of a plane dfJmefrll of the sphere, that is x (476) 2 mm2 * For a smooth solid composition, the measured hardness will generally be from 0003 to 05 Newton / mm2. Frequently, the hardness will be from 0003 to 01 Newton / mm2 n) Deposit whiteness Another proof of the properties of a composition is the whiteness, and hence the opacity of the composition, which is delivered on a surface when the composition is dragged through that surface To perform this deposition test , a sample of the composition was first applied to a test cloth under standardized conditions. The test cloth was a rectangular strip of black combed wool fabric of 9 cm by 15 cm. This was placed in an apparatus consisting of a metal base on which hinged a metal frame that defines a rectangular opening of 5 cm by 9 cm The test portion of the fabric was left in the base The hinged frame was placed on the fabric and 'secured to the base by means of two screws, thereby securing the test cloth in place, but exposing an area of 5 x 9 cm through the opening Soft sole composition in a dispensing container was maintained at ambient laboratory temperature (approximately 20 ° C), before it was required for measurement. A portion of the composition is then extruded from the container through the openings. dispensers at one end A heavy amount (05 g) of the extruded composition was spread evenly through the 5 x 9 cm area of the pure cloth enclosed by the frame. The spreading was performed using a spreading tool * of plastic After spreading the sample of the composition on the 10 cloth substrate, was removed from the apparatus and weighed to verify that the mass of the applied sample was 05 ± 001 g The fabric with applied sample of the composition was then valued twice for whiteness, once after one hour and again after 24 hours 15 This measurement was made using a Sony XC77 monochromatic video camera with a 16mm Cosmicar focal length lens, positioned vertically above a black table illuminated from a high angle using fluorescent tubes to remove shading The apparatus was initially calibrated using a 20 white reference card, after the fluorescent tubes had been lit enough to give a steady light output The fabric with a deposit on it was placed on the table and the camera was used to capture an image One area of the The image of the deposit was selected and analyzed using an image analyzer 5 Kontron IBAs This imaginatively divided the image into a large X .. 6 dp pixel array and measured the niv < the gri ^ of each pixel on a scale from 0 '(black) to 255 (white). The average of the exchange rate was calculated. This was a measure of the whiteness of the clouds, indicating a more white deposit. It was assumed that low numbers show a clear deposit that allows to see the substrate color. All the samples were prepared in triplicate and an average of the three measured values was reported.

F iii) Transmission of light 10 The translucency of a composition can be measured by placing a sample of standardized thickness in the light path of a spectrophotometer and measuring the transmittance, as a percentage of light transmitted in the absence of the gel. We have performed this test using a beam spectrophotometer 15 dual. The sample of the composition was emptied hot into a 4.5 ml test tube made of polymethylmethacrylate (PMMA) and allowed to cool to an ambient temperature of 20-25 ° C. Such probetsf gives a thickness of 1 cm of composition. The measurement was made at 580 nm, with an identical but empty specimen in the reference beam of the F 20 spectrophotometer, after the sample in the specimen has been sustained for 24 hours. We have observed that a composition that gives a tran- mitancy of only a fraction of 1% in this test is perceived by the eye as "translucent" when extruded in a thickness less than 0.5 cm. Upa transmittance measured at any temperature in the 25 range of 20-25 ° C is usually accurate adequately, but it more precision is required The above test procedures were applied to two soft solid compositions currently marketed, none of which is translucent when stored inside the dispenser. 5 existing product structured with castor wax and a silicone wax has a hardness by the texture analyzer of 00231 N / mm2, a whiteness measurement after 1 hour of 23 and a whiteness measurement after 24 hours of 42 A product of the competition, which is believed that it also has a structuring system of wax, had a hardness of 10 00318 N / mm2, a whiteness measurement after 1 hour of 20, a whiteness measurement after 24 hours of 83, and a% transmittance of 0004 *% EXAMPLES 15 The examples set out in the Tables below were prepared using a variety of materials, for which the suppliers and patented names are given in the following list 1 Rheopeart KL of Chiba Flour Millmg Co 2 GP-1 of Ajmomoto 2f 3 Dow Corning Silicone wax 4 Finstex TN from Fmetex 5 Parsol MCX from Givaudan-Roure 6 Sirtus M70 from Dalton 7 Volatile cyclic silicon (cyclomethicone) 25 CD245 from Dow Corning 4 * * ^ E¡, - 8 Summit-activated aluminum chlorohydrate Summit water content 77% 9 Aluminum chlorohydrate Reheis M 10 croDryMR glycine tetrachlorohydrex Al / Zr complex containing approximately 10% water by weight (AXAG - 7167 ) of Summit 11 AZAB - 7167 with water content increased to 19% by exposure in a humidity chamber at 85% relative humidity 12 Summit Fm milled activated aluminum chlorhydrate (water content 172%) 10 13 Syncrowaw ERLC esters C18 36 glycol (Croda) 14 Castorwax MP80, hydrogenated castor oil (CasChem) 15 Tpacontenyl vinyl pyrrolidone copolymer Antaron WP-660 (ISP) 16 SP173P paraffin wax (Strahl and Pitsch) 17 Guilini milled activated aluminum chlorohydrate 15 18 ground AAACH (super-active aluminum hydrochloride) 19 Fmsolv BOD (Finetex) 20 Finsolv SB (Fmetex) 21 Finsolv TP, mixture of C12 alkyl benzoate / dipropylene glycol benzoate / benzoate of PPG-15 esteapl ether (Fmetex) 20 22 1,1,5,5-tetrafen? l 1, 3,3,5-tetramet? ls? loxane PDM 7040 (Gelest) 23 Octyldodecanol, Ethanol G (Henkel) 24 Acid 12-h?

A solution of the thickener polymer and other structurants in the organic liquid (s) was made by mixing these materials, heating and stirring the mixture at a sufficiently high temperature so that the polymer and other structurants all are dissolved The mixture was then allowed to cool to 80-85 ° C, before the antiperspirant aluminum active was added. The mixture was then allowed to cool to 5-30 ° C above its gelling temperature ( determined in a preliminary experiment) and was emptied into dispensing containers as illustrated in Figs. 7 to 9 of the drawings. These were then allowed to cool to room temperature. The procedure was slightly varied if GP-1 was used. This was dissolved in ppi. the hot liquid mixture after which, the thickener polymer and any other structuring was added and dissolved. The general method Preparation was then continued as stated above with cooling to 80-85 ° C for the addition of the antiperspirant active, further cooling to 5 to 30 ° C above the gelling temperature (determined previously) and emptying into dispensing containers.
