Description

CLEANING COMPOSITIONS TECHNICAL FIELD The present invention relates to cleaning compositions.

In particular the invention relates to mild personal cleansing compositions which exhibit improved rinsing sensation in combination with good skin feel attributes, and foaming properties which are suitable for simultaneously cleaning and conditioning the skin and / or hair and which can be used, for example, in the form of foam bath preparations, shower bath products, skin cleaners, hands, face and body cleaners, shampoos, etc.

BACKGROUND OF THE INVENTION The mild cosmetic compositions must satisfy a number of criteria including cleaning energy, foaming properties and softness / low irritability / good feeling with respect to the skin, hair and ocular mucosa. The skin is made up of several layers of cells that line and protect the underlying tissue. The fibrous proteins of ceratin and collagen form the skeleton of their structure. The outermost layer is referred to as the stratum corneum. Similarly, the hair has an outer protective coating that covers the fiber of the hair called the cuticle. Anionic surfactants can penetrate the stratum corneum membrane and the cuticle and, through delipidization, destroy the integrity of the membrane and lose barrier and water retention functions. Such interference with the protective membranes of the skin and hair can lead to a rough sensation of the skin and irritation of the eyes and can eventually allow the surfactant to trigger the irritation that creates an immune response. The ideal cosmetic cleansers should gently cleanse the skin or hair without interrupting the structural lipids and / or drying the hair and skin and without irritating the ocular mucosa or making the skin dense after frequent use. The most sparkling soaps, shower bath products, shampoos and bars fail in this regard. Certain synthetic surfactants are known to be mild. However, a major drawback of some mild synthetic surfactant systems when formulating for shampooing or personal cleansing is that they have what could be described as a "slippery" or "slippery" rinse sensation that is not pleasant to some consumers. The use of certain surfactants such as potassium laurate, on the other hand, can yield an acceptable rinsing operation but at the expense of the clinical smoothness of the skin. These two facts make the selection of suitable surfactants in the formulation process of rinsing sensation and benefit of softness an act of delicate balance.

In this way, there is a need for personal cleansing compositions that provide a "non-slip" rinsing sensation, while at the same time having excellent skin smoothness, In addition to excellent product characteristics, such as foam, cleaning, stability, thickening, rheology and attributes of skin sensation in use. Certain polyalphaolefin oils are known for their use in personal cleansing compositions for the skin and hair. References for the use of such oils in personal cleansing formulations are found in WO 97/09031, E.U.A.-A-5441730, WO 94/27574, EP-A-0692244, WO 96/32092 and WO96 / 06596. Hydrophobically modified silicone oils are also known for their use in personal cleansing compositions and are described for example in JP 05-310540. Surprisingly, it has been found that personal cleansing compositions have a "non-slip" rinsing sensation that at the same time excellent softness characteristics are provided by a certain combination of so-called "slippery" and "non-slippery" surfactants together with certain water-soluble oils, such as certain polyalphaolefin oils or hydrophobically modified silicone oils. While not wishing to be bound by theory, the feeling of "non-slip" rinse is considered associated with an increase in wet skin friction. An important mechanism for the action of said -M-.l-MÉ-1-ÍÉBÉÉIÍÍÍÍÍil oils is considered as the ability of these to deposit and change the surface energies of the skin, that is, make the surface of the skin more hydrophobic. During rinsing, the water film is considered to be the lubricant for the skin, since the hydrophobic character of the surface is increased so that the water film becomes unstable and the surface dehumidifies. As a result, the water film first becomes thin and then moves, allowing some direct contact between the surfaces. Both changes increase friction and produce "non-slip rinsing".

BRIEF DESCRIPTION OF THE INVENTION According to the present invention, there is provided a rinse-off personal cleaning composition comprising water and surfactant wherein the composition comprises less than 8% of a selected first surfactant and a crystallizing anionic surfactant and more than 3% by weight of a second surfactant selected from a non-crystallizing anionic surfactant, amphoteric surfactant, nonionic surfactant and zwitterionic surfactant, and mixtures thereof, and wherein the composition has an average rinse sensation value of 3.5 or less according to It is measured by the rinsing sensing panel test.

The compositions of the present invention provide an improvement in the rinsing sensation while at the same time being exceptionally gentle for the skin. All concentrations and ratios herein are by weight of the cleaning composition, unless otherwise specified. The surfactant chain lengths are also based on the average weight chain length, unless otherwise specified.

DETAILED DESCRIPTION OF THE INVENTION Liquid cleaning compositions herein comprise water and surfactants including a crystallizing anionic surfactant and a non-crystallizing anionic surfactant. The compositions herein have a value of sensation average of 3.5 or less as measured by rinse test rinse feel panel described below. Preferably, the composition has an average rinse feel value for the composition of 3.25 or less, more preferably of 3.0 or less. In the preferred embodiments, the composition has an average rinse sensation value on the scale of 3.5 to 1.0. As is E.U.A herein, the term "rinsing sensation" refers to the feeling of the skin during the procedure of the Ii ^ ^ ^^^^^^ ík &? Faith ^^^^^ foam skin rinse after cleaning with a rinse composition. The type of rinsing sensation that is provided by the compositions of the present invention can be described by terms such as "non-slip" rinsing sensation, a "soap-like" rinsing sensation and a "non-slipping" rinsing sensation. or "not viscous". A "non-slip", "soap-like", "non-slip" or "non-viscous" rinsing sensation can be detected by an increase in friction between the hand and skin during the skin rinsing procedure. As is E.U.A herein, the term "water-soluble" in relation to oils, refers to a material that is substantially water-soluble distilled at room temperature without the addition of other adjuncts or ingredients such as those described herein.

The term "crystallizing anionic surfactant" refers to an anionic surfactant in which the monovalent salt of said agent is used in the present invention. Surfactant (eg, sodium, potassium or ammonium salt) is precipitated in the presence of calcium ions. In addition, the term "crystallizing surfactant", as used herein, refers to a surfactant that is precipitated by making a substantially clear solution turbid if a 10% solution of said surfactant (10% solution) being at a temperature at which it is substantially clear (between 30 and 50 ° C, preferably around 30 ° C)) progressively diluted with 3.56 mmoles of Ca 2+ ions (20 ° C hardness of water, at the same temperature as 10% of surfactant solution) in a molar ratio of about 1: 1 to about 2: 1 of Surfactant: calcium. This effect can also be observed as a deviation from the ideal in the surface tension profile of the agent surfactant. The crystallizing anionic surfactants provide a "non-slip" rinsing sensation in the skin. The term "non-crystallizing" anionic surfactant, as used herein, refers to an anionic surfactant that does not exhibit the performance of a crystallizing surfactant as defined herein. above, that is, one that does not precipitate in the presence of calcium atoms.

Technical sticking test method The sticky technical test method described herein was developed using the basic tack theory. The theory The basic tackiness was summarized in the Stefan equation that describes the viscous separation resistance for two disks connected by a thin liquid "pressure film". This is also used in other areas of technology where the assessment of tackiness is critical, for example, printing ink. The reference to the theory of basic tackiness can found in the article by Phillips, J.C. and Chaing, A. C, "Low Speed Tack Measurements of Fluids and Inks," J. Applied Polymer Science, 1995, 58, 881-89. - ^ .. ^^^ aTA ..-. ". . ^? g.25 ^ »a-a¿.

A simplified form of the Stefan equation is shown below for the maximum force, F, applied for time, t, to separate the disks that have a radius r connected by a liquid film that has a thickness h and viscosity ?: 3. p.?r4 F = 8.t.h ' From this equation, and when the surfaces are separated to a speed v, the force of separation becomes: F = k. ? v (2) where k is a constant if h and r are fixed in a series of comparative experiments. The above is the basis for determining the relative tackiness of oils. The instrument used is an Instron 4301 voltage tester, coupled with a 10N load cell and 10 mm diameter of a soft steel plate in the movement crosshead. The fixed lower plate is also made of mild steel and has a flexible rubber spring (56 N / mm) and leveling device coupled with the base of the instrument. The same plates and spring assembly are used to establish the comparison measurements. The plates are approximated and placed in parallel using the leveling device. The contact force is calculated for each oil to give a consistent film thickness of the equation: F = 0.0726. ? (3), where ? is the viscosity of the oil in Pa.s, F is the contact force in N. The machine is prepared to stop a compression force of F. Approximately three drops of oil are placed on the bottom plate, directly below the plate higher. The plates are joined, maintaining the required force for one minute. The tension speed is set at 1 mm / min and the maximum force is recorded as the stickiness observation. The plates were joined again and a total of three observations were collected. As a verification for the most remote observations, the scale / average for the three observations should be less than 10%. If not the above happens, three other observations are collected. Three reference oils are included in each series of comparisons, and these are Indopol H100, Viscasil 5M (Dimethicone) and SF1000. The three oils cover a stickiness scale and their data are used to determine the relative tackiness of the other oils and to evaluate the method of reproducibility. In each experiment, the maximum force ratio for an oil is expressed as a percentage of the value for Viscasil 5M (Dimethicone), and this is the stickiness index. When the above is correctly established, a coefficient of variation of less than 15% is expected in said data. The significant differences of a series of oils are determined using an ANOVA form of logarithm of transformed force data.

Examples of preferred polyols are sugars, including monosaccharides and disaccharides, and sugar alcohols. Examples of monosaccharides containing four hydroxyl groups are silose and arabinose and sugar alcohol derived from silose, which has five hydroxyl groups, for example, xylitol. The monosaccharide, erythrose, is not suitable in the practice of this invention since it only contains three hydroxyl groups, but the sugar alcohol derived from erythrose, for example, erythritol, contains four hydroxyl groups and can be used accordingly. The five Suitable hydroxyl groups containing monosaccharides are galactose, fructose and sorbose. Sugar alcohols containing six OH groups derived from the products of hydrolysis of sucrose, as well as glucose and sorbose, for example, sorbitol, are also suitable. Examples of disaccharide polyols that can be used include maltose, lactose and sucrose, the which contain eight hydroxyl groups. The preferred polyols for preparing the polyesters for use in the present invention are selected from the group consisting of erythritol, xylitol, sorbitol, glucose and sucrose. Sucrose is especially preferred. The polyol starting material that has at least four groups The hydroxyl is esterified in at least four of the OH groups with a fatty acid containing from about 8 to about 22 carbon atoms. Examples of said fatty acids include caprylic, capric, lauric, myristic, myristoleic, palmitic, palmitoleic, stearic, oleic, ricinoleic, linoleic, linolenic, eleostearic, arquid, arachidonic, behenic, and erucic. Fatty acids can be derived from fatty acids that occur naturally or synthetically. These can be saturated or unsaturated, including positional and geometric isomers. However, in order to provide preferred liquid polyesters for use herein, at least about 50% by weight of the fatty acid incorporated in the polyester molecule must be unsaturated. Oleic and linoleic acids and mixtures thereof are especially preferred. The polyol fatty acid polyesters useful in this invention should contain at least four fatty acid ester groups. It is not necessary that all of the hydroxyl groups of the polyol be esterified with fatty acid, but it is preferable that the polyester contains no more than two unesterified hydroxyl groups. More preferably, substantially all of the hydroxyl groups of the polyol are esterified with fatty acid, ie, the polyol portion is substantially completely esterified. The fatty acids esterified for the polyol molecule can be the same or mixed, but as noted above, a substantial amount of ester and unsaturated acid groups must be present to provide fluidity. To illustrate the above points, a sucrose acid triester may not be suitable for use herein because it does not contain the four fatty acid ester groups required. A sucrose fatty acid tetra ester of sucrose may be suitable, but is not preferred because it has more than two unesterified hydroxyl groups. An acid ester - ^ »> «AA-. ^^ ÍA. ^^. ^ ..

Sucrose sucrose fatty may be preferred because it has no more than two unesterified hydroxyl groups. Highly preferred compounds in which the hydroxyl groups are esterified with fatty acids include the liquid sucrose octa-substituted fatty acid esters.

The inner forearm and both hands are moistened for 5 seconds. 1.7 ml of the product to be evaluated is applied to wet hands. By using moderate pressure, the product foams on the hands with 6 rotations in 6 seconds (one full rotation per second). The foam is applied to the inner forearm (from the wrist to the elbow to the wrist) for 10 seconds using moderate pressure. The foam is left on the forearm for 30 seconds. The product is rinsed from the hands. The forearm is rinsed under water flow for 15 seconds with ^ ¡^ OMuMm-i- ^ u ± i ^ ** - ^ * - ******* ^ the reflux of water starting at the elbow. During this time, the wet skin sensation is evaluated in the following periods: 3 seconds, 9 seconds and 15 seconds. This is done by hitting the inner forearm from the elbow to the wrist three times using light pressure and starting where the water flows in the arm. The rinse stops after 15 seconds and each evaluation of wet skin sensation is marked on the evaluation sheet.

Experimental design A randomized incomplete block design should be used to compare eight products using eight subjects and two treatment sites per subject.

Calculations A statistical package capable of carrying out the variation analysis (for example, Statgraphics Plus version 2.1) should be used. The analysis must be carried out at 90% of the level of significance, using the evaluation period as variable and dependent product, the panelist and the site as factors. For the eight subjects, this design has 80% energy to show differences of 0.71% to 90% of meaning.
