Description

Description: FIELD OF THE INVENTION The present invention relates to fiber conditioning compositions. More specifically, the present invention relates to a shampoo comprising a liquefied poly-lower alkylene, wherein the hair after washing with the shampoo has a more suitable conditioning condition (comb-through, cohesive hair, low electrostatic charge). State).

BACKGROUND OF THE INVENTION Fiber conditioning compositions, such as compositions for treating laundry textile materials, including softeners that impart a softer texture to the washed fabric and prevent static charge after drying in an automatic washer dryer. Include cationic conditioning agents such as quaternary ammonium halides, and such quaternary ammonium compounds are also included in hair rinses. Polyethylene has also been incorporated into compositions for treating fibrous materials (including human hair) as a lubricant for said materials. Mineral oils have also been used as lubricants and polishes in fiber materials, including hair. Similarly, such substances have also been incorporated into shampoos, some of which are based on anionic synthetic organic surfactants. However, the present invention is believed to be novel and disperses the normally water-insoluble poly-lower alkylene in water by using a normally liquid hydrocarbon, such as mineral oil, in the presence of a cationic surfactant fiber conditioning agent. It has not been previously known that it can be solubilized or liquefied prior to dispersing or dispersing poly-lower alkylenes (eg, polyethylene) in the presence of a cationic surfactant fiber conditioning agent of this kind in a conditioning composition. It was not known that the conditioning of fiber materials (especially human hair) after treatment with (eg an anionic synthetic organic surfactant shampoo) could be significantly improved.

(Constitution of the Invention) According to the present invention, a cationic surfactant fiber conditioning agent, usually comprising a water-insoluble poly (lower alkylene) and / or oxidized poly (lower alkylene), and a solubilizing agent for the poly (lower alkylene), Makes the poly lower alkylene water-dispersible in the presence of a cationic surfactant fiber conditioning agent and water, so that the dispersed poly lower alkylene significantly enhances the fiber conditioning effect of the cationic surfactant fiber conditioning agent, fiber conditioning. A composition is provided. The present invention also provides the composition in the form of an anionic synthetic organic surfactant shampoo, the use of the composition (and shampoo), and a method of making the same.

The cationic surfactant fiber conditioning agent, which is the primary conditioning agent in the fiber conditioning composition, is preferably a quaternary ammonium salt, although other cationic surfactant compounds having fiber conditioning properties can be used, at least in part. Thus, imidazolinium salts and betaines and U.S. Pat.
Alternatively, cationic substances as described in EP 077 can be used, as well as complexes of cationic and anionic surfactants and cationic surfactants and organic acids (eg.
A complex with citric acid) can also be used. Such conjugates are disclosed in U.S. Patent Application Nos. 06/916067, 06/916068, and 06/916069. Suitable quaternary ammonium salts are of the formula R ¹ R ² R ³ R ⁴ N ⁺ X ⁻ , wherein at least one R is lower alkyl, at least one is higher alkyl, and the rest are higher and / or Lower alkyl). Preferably, R ¹ has ¹ carbon atom
And R ² and R ³ have 10 carbon atoms.
4040 higher alkyl, R ⁴ is the lower alkyl or the higher alkyl, and X is a halide, lower alkanol sulfate, or lower carboxylic acid radical (eg, chloride, bromide, methosulfate, ethosulfate, acetate, )). Lower alkyl generally has 1 to 3 or 4 carbon atoms, preferably has 1 or 2 carbon atoms, and is more preferably methyl. Higher alkyl is
It has 10 to 40 carbon atoms, preferably has 12 to 18, 20 or 22 carbon atoms, more preferably 14 or 16 to
It has 18 or 22 carbon atoms, for example on the order of 16.
The anion is preferably a halogen such as chlorine, bromine or iodine, with chlorine and bromine being preferred, and chlorine being more preferred.

The number of lower alkyl will preferably be one or two, and the number of higher alkyl will generally be two or three. It has been found desirable that the total number of carbon atoms of the quaternary ammonium salt be at least 30, preferably at least 34.
Most preferably, the quaternary ammonium salt will contain three higher alkyls and one lower alkyl, and will be chloride. The most preferred higher alkyl is cetyl, the most preferred lower alkyl is methyl, and the most preferred quaternary ammonium halide is tricetylmethylammonium chloride. However, other quaternary ammonium halides, such as distearyl dimethyl ammonium chloride, dilauryl dimethyl ammonium bromide, stearyl cetyl dimethyl ammonium chloride, and other as at least a portion of the fiber conditioning cationic surfactant component of the composition. It is also within the scope of the present invention to use a hair conditioning cationic surfactant.

The second fiber conditioning component of the composition is a normally solid, water-insoluble poly-lower alkylene. Such polymers have a solubility of less than 1 g / 100 ml of water and often can be less than 0.1 g / 100 ml of water. In an aqueous medium,
It imparts little conditioning effect to the fibrous material to which this type of aqueous composition is applied (eg, human hair), even when present in a very fine form. It also has similarly low conditioning activity from other media suitable for application to the fibrous material for conditioning. However, in the present composition, when used with a normally liquid hydrocarbon, such as mineral oil, the water-insoluble poly-lower alkylene is activated and cooperates with the cationic surfactant fiber conditioning agent also present in the composition. Surprisingly, it enhances the fiber conditioning effect of this type of cationic conditioning agent.

As the second conditioning agent, for example, a hydrocarbon polymer having 1 to 5 carbon atoms and having a molecular weight of 1000
A variety of poly-lower alkylenes, which are noted to improve the conditioning effect of the cationic conditioning agent at ~ 10000 or more, may be used, but the polymer is generally a polymer of ethylene or propylene and may be a linear methylene group or various It is believed to have a degree of branching, and usually its molecular weight will be 1000-5000, preferably 1000-4000, more preferably 2000-2500, most preferably 2000 or 2100, ie around 2000. Oxidized forms of these polyalkylene polymers can also be used, and they can produce larger hydrocarbons with terminal carboxyl groups. Polymers of this type, particularly optimal are anionic synthetic organic surfactants in the presence of a liquefied fraction of mineral oil or other relatively low molecular weight hydrocarbons (usually liquids) or equivalent solubilizers of poly-lower alkylene. Or they could be dispersed in an aqueous medium containing a detergent.

The poly-lower alkylene solubilizing agent renders the polymer water-dispersible in the presence of a cationic surfactant fiber conditioning agent and also in the presence of an anionic synthetic organic surfactant or detergent. The use of a solubilizing agent solubilizes the normally solid, water-insoluble poly-lower alkylene, so that it will be dispersed and suspended in an aqueous medium without phase separation or polymer sedimentation. Also, surprisingly, the presence of the solubilizer significantly enhances the fiber conditioning effect of the cationic surfactant, presumably due to the enhanced effect of the second conditioning agent. The solubilizer is preferably a normally liquid hydrocarbon, the molecular weight of which is between 150 and 1000, preferably between 300 and 800,
More preferably it will be between 400 and 700, most preferably between 500 and 600, e.g.

The hair conditioning composition can be in any form and can be used in various conditioning applications. Preferably, it is in the liquid form of an aqueous medium, but may be used in other useful forms. Thus, it may be in gel, paste, cream, foam or aerosol form, and may be in solid form (bar), which is dispersed in water or other aqueous medium during use. A preferred composition of the present invention is a shampoo that usually contains a synthetic organic detergent (eg, an anionic detergent) and water. Optionally, amphoteric, zwitterionic or nonionic detergents or surfactants are utilized in such shampoos instead of or with anionic detergents. A wide variety of suitable detergents are available from McCutcheon's Detergents
and Emulsifiers, North American Edition, 1984. Suitable anionic detergents (also described in the above references) are called "sulphated" or "sulphonated".
These have 8 to 22 carbon atoms, preferably 10 to 18, more preferably 10 to 16 or 18, most preferably 12 to 16 or
18 water-soluble lipophilic sulfates and / or sulfonates. Among such anionic detergents there may be mentioned, for example, higher alkyl sulfates, paraffin sulfonates, olefin sulfonates, monoglyceride sulfates, higher fatty alcohol lower alkoxy sulfates, and linear higher alkyl benzene sulfonates. The optimal higher alkyl sulfate has the number of carbon atoms
The higher alkyl lower alkoxysulfates are those having 12 to 16 carbon atoms, with the highest alkyl lower alkoxysulfate having 16 to 18 carbon atoms, where the higher alkyl is lauryl, having 2 or 3 ethoxy groups per mole. However, this type of alkyl preferably has 12 to 16 carbon atoms and the alkoxy content can be 1 to 20, for example 2 to 6 ethoxy groups per mole. The preferred higher fatty alcohol sulfate is lauryl sulfate, and a particularly preferred higher fatty alcohol poly-lower alkoxy sulfate is sulfated di- or tri-ethoxylated lauryl alcohol. Most preferably, the anionic detergent is a mixture of higher alkyl sulphate and higher alkyl ether sulphate, one of which is present in a higher proportion, the ratio of the amounts of these components generally being from 10: 1 to 1:10 or It will range from 7: 1 to 1: 7, for example 1: 5 and 5: 1. Anionic detergents are used in the form of their water-soluble salts and are usually alkali metals (eg, sodium, potassium), ammonium, amines (eg, dimethylamine, trimethylamine), or lower alkanolamines (eg, triethanolamine, diethanolamine, Monoethanolamine). Examples of useful detergents are ammonium lauryl sulfate, sodium lauryl diethoxy sulfate,
Ammonium lauryl triethoxy sulfate, sodium C ₁₆ olefin sulfonate, sodium C ₁₄ paraffin sulfonate, sodium coco monoglyceride sulfate, triethanolamine cetyl sulfate, and dimethylamine myristyl sulfate. However, for best results, higher alkyl sulfates or mixtures of higher alkyl sulfates and higher alkyl ether sulfates (e.g.,
Lauryl sulfate and lauryl diethoxy or triethoxy sulfate) are preferred,
In the case of the mixture, the higher alkyl sulfate is present in a higher proportion and the ammonium or triethanolamine anionic detergent salt is also present in a higher proportion.

The water used in the aqueous composition of the present invention (including a suitable shampoo) is preferably deionized water having a hardness of 10 ppm or less in terms of calcium carbonate, but other water can be used depending on the circumstances. . It is preferred to use irradiated deionized water to exclude microorganisms from the composition of the present invention. Various mixing vessels, tanks, pipes and containers will also be kept with great care and care.

In addition to the necessary components of the conditioning composition of the present invention and the shampoo of the preferred embodiment thereof, they include various adjuvants, which may impart desirable properties to such compositions. Those known in the art or those determined by the present inventors and their fellow researchers to have the desired effect when formulated into the present compositions. Such adjuvants include, inter alia, paraffin, petrolatum, microwax and isoparaffin, all of which supplement mineral oil and act as solubilizing hydrocarbons; to improve the hair conditioning effect of fiber treatment compositions such as shampoos. Useful higher fatty acid esters of lower alcohols, lower fatty acid esters of higher alcohols, higher fatty acid esters of higher alcohols, as described in US patent application Ser. No. 07/369361; thickeners such as lower alkylcellulose, hydroxy lower Gums such as alkylcellulose, xanthan gum (which also act as stabilizers); foam modifiers and modifiers such as betaine, higher fatty acid triglycerides, lower akanolamides (eg _{cocoamidopropyl petaine} , C _{18- 36} acid triglyceride, lauri Pearlescent agents such as ethylene glycol mono- and distearates; auxiliary conditioning agents such as silicones, amino-substituted silicones ("Fiber conditioning compositions containing amino silicone conditioning agents" dated the same as this application).

The proportions of the various components of the composition of the invention are such as to significantly enhance the fiber conditioning effect. Such an improvement in the fiber conditioning effect of the conditioning composition is due to the fact that the proportion of cationic surfactant fiber conditioning agent is the fiber conditioning proportion, the proportion of water solids insoluble in normal state, the proportion of cationic surfactant fibers when the polyethylene is dispersed in water. The proportion of the conditioning agent is sufficient to enhance the fiber conditioning effect, and the proportion of liquid hydrocarbons or mixtures thereof liquefy normally solid polyethylene,
Obtained when it is in sufficient proportion to make it water-dispersible in the presence of the above amounts of quaternary ammonium salt and water.
In a hair conditioning composition containing an anionic synthetic organic detergent, and a shampoo containing this kind of anionic detergent in water, the proportion of the anionic detergent is a surface activity proportion, but is often a washing proportion depending on the intended use, And the proportion of water will be sufficient to form the dispersion medium as in the case of shampoo.

In shampoos, the proportion of each component is generally 8 or

10-15% alcohol sulfate or alcohol ether sulfate and 1-5% alcohol ether sulfate or alcohol sulfate, even more preferably 10 or 11-13 or 14% alkyl sulfate and 1-4% It would be an alkyl ether sulphate, for example 12.5% ammonium lauryl sulphate and 2.5% sodium lauryl diethoxy ether sulphate.

As mentioned above, the fiber conditioning and hair conditioning compositions of the present invention can be in a variety of physical forms, the preferred form being a liquid, and the preferred embodiment of the present invention is a hair conditioning shampoo. Such commercially acceptable compositions should be chemically and physically stable, will not unacceptably deteriorate on storage, will not separate or settle, and will not cause undesired changes in viscosity. It is. The shampoo of the present invention has a desired viscosity in the range of 1000 to 15,000 centipoise at room temperature (25 ° C.), and preferably has a viscosity of 3000 to 6000 at said temperature.
cp, more preferably about 3500-4000 cp. The shampoos of the present invention do not settle upon storage and substantially maintain their improved hair conditioning properties.
Also, while the viscosity is maintained at about the same as when the shampoo was made, some of the expected shampoos increase in viscosity shortly after the end of the manufacture, thereby imparting the desired working viscosity to the product.

Improved hair conditioning, as compared to a control in which both polyethylene and mineral oil have been removed, is easily recognized by a randomly selected user of the conditioning composition or shampoo and can be used in wet or dry conditions. It can be examined by standard methods to assess comb combability, hair clumping, and electrostatic charge retention (related to unpleasant hair scattering). After washing with the composition of the present invention, the user of the shampoo notices that the comb is better in the wet or dry state compared to the control, and the accumulation of static charge and unpleasant hair scattering are unlikely to occur. There will be. Scientific tests have also shown that after treating hair with the conditioning composition of the present invention or after washing with the shampoo of the present invention, the power required to comb a standard hair comb is used for the same purpose. It is proved that it is smaller than the case. In addition, hair spatter appears less than when the hair is washed with the control product. Such results can be confirmed by a panel test, in which
Several experienced assessors will use both the experimental and control products in a blind test and evaluate them for good combat, static electricity, and hair simplicity as described above.

The use of the compositions of the present invention (including shampoos) need not differ from the normal use of hair conditioning compositions and shampoos. The conditioning agent is applied in standard amounts at room temperature or at a slightly elevated temperature and is left in contact with the hair for various times, depending on the degree of conditioning desired. Generally, conditioning agent and hair are 15-50 ℃,
The contact is preferably performed at a temperature of 20 to 40 ° C. for 30 seconds to 10 minutes, preferably 1 to 5 minutes. The amount of composition applied is generally from 0.1 to 25 g, often from 0.2 to 10 g, frequently from 0.1 to 25 g, based on the non-aqueous and non-solvent (non-alcoholic) components of the composition.
Will be in the range of 5-2g. In the case of shampoo, the amount used is 0.5 to 50 g per use, often 2 to 15 or 20
g, often in the range of 5-10 g. The applied composition is spread on the hair with a brush and / or a comb and then rinsed off, left on the hair, or partially wiped off with a towel or the like. If a shampoo is used to wash and condition the hair, a sufficient time (usually from 1 to 5) to obtain a satisfactory conditioning of the hair.
Minutes) Leave it on the hair as an aqueous foam, rinse it off with water, then comb the hair in a wet state, dry it with a blow dryer, etc., and use the brush or comb in the dry state to obtain the desired hairstyle Trim.

No special measures are required to prepare the compositions of the present invention (including shampoos), but in order to obtain the best stability of the shampoos and aqueous products during storage and use, an elevated temperature (e.g. At 60 or 70-90 ° C.) to form a water-soluble dispersion of water-soluble lipophilic sulphate and / or sulfonate and adjuvants at elevated temperature (70-90 ° C.) in a liquid mineral oil with a cationic conditioning agent (eg halogenated Quaternary ammonium) is normally dissolved and / or dispersed with the solid polyethylene and the two solutions and / or
Or it may be most desirable to mix the dispersions together to form a stable dispersion. If an adjuvant is present, those that dissolve and / or disperse in water are mixed with the aqueous phase material and those that do not dissolve or disperse in aqueous media (eg,
(Paraffins, isoparaffins, microwaxes) are mixed with the above three lipophilic substances or added to the mixture of aqueous and lipophilic substances before or after cooling to room temperature. Generally, the fragrance is added to the mixed ingredients after cooling to avoid their loss due to volatilization or decomposition of the ingredients during heating. Without following the above method, indiscriminate blending of the components results in an unstable product that separates or precipitates during storage, and such an unstable composition is a stable product made according to the method of the present invention. Conditioning compositions and shampoos tend to exhibit inferior conditioning properties.

The following examples illustrate, but do not limit, the invention. Unless otherwise specified, all parts are by weight and all temperatures are in ° C.

The conditioning composition of Formula A is prepared by mixing together the water-soluble and water-dispersible materials of Formula A with all or substantially all of the water of Formula A (if not using all of the water at this stage, The remainder of the water is added to the mix of the heated aqueous portion and the heated lipophilic melt or dispersion); polyethylene, mineral oil, paraffin wax and other "liquid" hydrocarbons together heated to about 80 ° C; Mixing the mixes together for 10 minutes with stirring; a stable shampoo prepared by storage for 1 month at elevated temperature (equivalent to storage for at least 1 year at room temperature) does not separate or settle. Was. The shampoo was tested for conditioning properties by at least five experienced conditioning effectors. Panel test members examine the hair washed with the above shampoos, rinsed with water and dried to determine various conditioning properties, including combability in wet and dry conditions, static electricity, hair splashing and collectability. The hair was evaluated.

A control shampoo (B), which had the same formulation as the shampoo of Formula A but did not contain polyethylene and mineral oil, but was replaced by water, was prepared in a similar manner. Both compositions are about 6.
It had a pH of 5 and a viscosity of about 3500 or 4000 centipoise at 25 ° C. Control shampooed, rinsed and dried hair was evaluated by panel test members in the same manner as performed with the A composition, and these ratings were evaluated for the A composition washed, rinsed and dried hair And compared. Panel test members found that the conditioning effect obtained from the A composition was significantly better than that obtained from the B composition. When evaluated numerically on a scale from 1 to 5 (the larger the number, the better the conditioning effect), the grade of B treatment is about 2
And the grade of the A treatment was about 5.

The shampoo of the above formulation was prepared in the same manner as the shampoo of Example 1, and the melt of the lipophilic substance contained polyethylene, mineral oil, paraffin wax and isoparaffin. The resulting shampoo has a pH of about 6.5 and about 3 at 25 ° C.
It has a viscosity of 500 or 4000 centipoise, is stable on storage, retains its initial improved hair conditioning properties, sediments, separates, even when stored for up to one year.
Or showed no other degradation.

When tested against a control shampoo of the same formulation except without polyethylene, it had significantly better hair conditioning properties. By comparing control shampoo-washed hair with shampoo-washed hair of the formula of the present invention, we found that the wet and dry combs showed better combability, easier hair cohesion, reduced static electricity and reduced scattering. Overall rating.

In the above formula, the anionic detergent is changed, the ratio is changed, and an auxiliary hair conditioning agent is added. And it confirms that the presence of polyethylene desirably improves the conditioning properties of the hair conditioning shampoo when solubilized by mineral oil. The inventive products of Examples 1 and 2 are believed to be significantly improved over this type of conditioning shampoo of the prior art, primarily due to the presence of the poly-lower alkylene conditioning agent along with the mineral oil and the cationic conditioning surfactant. The conditioning differences are not only confirmed by instrument measurements or experienced observers, but are also apparent to the average consumer, a user of this type of product. After shampooing, the combs in wet and dry conditions are noticeably better. It also makes it easier to set and organize the hair, at least in part because of the reduced generation of static electricity and the reduced tendency of the hairs to repel each other. cause).

Although the compositions described in Examples 1 and 2 are hair conditioning shampoos, the present invention is applicable to fiber conditioner formulations and hair conditioning compositions other than shampoos. Thus, products of this type can be used for conditioning other natural fibers (eg, cotton, linen, wool) and synthetic fibers (eg, nylon, polyester, acrylic, acetate).
Also, the cation conditioner, polyethylene and mineral oil of the essential components of the compositions of Examples 1 and 2 are used as a solution in alcohol or other suitable solvent,
Alternatively, if converted to a gel or other suitable form and applied, for example, by spraying on the hair, smearing and brushing as a liquid, or rubbing on the hair as a gel, the hair will obviously have such an application Conditioned by law. If this type of application is made from an aqueous system, mineral oil and other solubilized hydrocarbons may be omitted from the composition (in which case the shampoos suitable for use will not be dispersed or emulsified to a satisfactory degree). Is not obtained, but better conditioning is obtained.

Example 3 Examples 1 and 2 were modified so that the resulting shampoo contained only the necessary components anionic surfactant, cationic surfactant conditioner, polyethylene, solubilized liquid hydrocarbon (mineral oil) and water. With the elimination of various adjuvants from the product, the resulting shampoo has a lower viscosity than desired, but can be used well to wash and condition the hair. If the mineral oil is omitted from the formulation, neither polyethylene can be dispersed or emulsified in the system. When the polyethylene is solubilized using lighter or heavier other mineral oils or other hydrocarbons that are normally liquid in place of the above mineral oils, the conditioning is better than similar compositions without such solubilizers. However, often such other hydrocarbons are cosmetically unacceptable and can be toxic. Mineral oil is considered non-toxic and helps to shine hair after shampooing and often acts as a good solubilizing agent for polyethylene. These properties make mineral oil a very suitable solubilizer in the composition of the present invention.

By changing any of the various necessary components of the example conditioning compositions and shampoos to the other components listed herein, for example, the anionic detergent may be triethanolamine lauryl sulfate, sodium myristyl sulfate, potassium cetyl sulfate.
