xmü shampoos on your body

You IDrfinäung ibetrdfft a iiaarwascii ^ ea-SaiirBn and: ShampoD ^? s zu se.ine; r DureiifütariAng, especially shampoos that contain a resinous substance.

Shampoos have already been proposed that are resinous Substances contain various cosmetic properties around the hair go zn. There are generally: two types of shampoos. .; . ■, -.

In one type, the resinous substance is in both water and also in the aqueous surfactant system from which the shampoo "consists, soluble. He pulls nouns up on the hair and thus becomes partially adsorbed on the hair during shampooing. The resinous substance is easily adsorbed, but it will however, due to its water solubility, it is also easy when rinsing removed again. That is why you can use shampoos that are water-soluble contain resinous substance, generally only slightly

lower cosmetic effects on hair, since only lower amounts of the resinous substance on the hair after washing and rinsing lag behind.

Shampoos are described in US Pat. Nos. 3,313,734 and 3,400,198 which are resinous and solubilized in a special surfactant system Contain polyalkylenimines. The polyethyleneimines are in concentrated shampoo, but will precipitate when diluted. Therefore, when diluting the shampoo during the Shampooing a deposition of the polyalkylenimine on the hair, whereby an easy hairdressing and a good shape retention of the laid hair should be guaranteed.

When examining the shampoos described in the aforementioned patents, however, it was found that the Hair-deposited, water-soluble, polymeric substances easily dull the hair and adversely affect the grip.

It has now been found that resinous substances, which impart body and good dimensional stability to the hair ("set retention ¹¹ ), are deposited from an aqueous shampoo by changing the solubility of the resinous substance. This then occurs when an aqueous surfactant solution containing a water-miscible organic solvent is diluted during shampooing.

Thus, the invention relates to aqueous shampoos that are applied to the hair body and imparting dimensional stability, containing

Furthermore, the invention / hair washing method for achieving body and dimensional stability, which consists in applying a shampoo according to the invention to the hair. The term "body" is used for hair that appears fuller and thicker, is easier to style and accepts and holds a curl more easily than hair that has no body ... .

Resin-like substances suitable for the purposes of the invention are, for example, polyvinyl ethyl ether resins, alkyd resins, polyketone resins, vinyl acetate resins, Acrylic resins, sucrose acetate isobutyrate and mixtures thereof.

The resinous materials can be used together with wax-like substances that give hair body and improve his general condition ( "condition"). Suitable waxy substances are, for example, coconut amide, ethoxylated lanolin, stearyl amide or ethoxylated higher fatty alcohols.

In addition, organic oils such as lanolin alcohol, cetylated castor oil or

Mineral oil fractions are used as hair lubricants, which nourish the hair and make it easier to style leaves.

Preferred resinous substances are polyketone resins, sucrose acetate isobutyrate and polyvinyl ethyl ether resins, both alone and in admixture or in combination with those in DT-PA

described rosins ("wood rosins") can be used.
The mixing ratios of, for example, polyketone - sucrose acetate isobutyrate and rosin polyketone can be from about

1: 9 to 9: 1, preferably 1: 5 to 5: 1, vary. Mixtures of resinous materials are desirable because they impart additional desirable cosmetic properties to the hair.

The content of resinous substances in the shampoos is approximately

2 to 60 percent, preferably about 3 to 20 percent based on the weight of the shampoo.

In order to obtain optimum results with the shampoos according to the invention, which impart body and shape retention to the hair, the softening point of the resinous substance is preferably about 30 to 50 ^° C. The method used for the purposes of the invention to determine the softening points is described in the leaflet "Wood Rosins, Modified Rosins and Related Resins "by Hercules Powder Company.

As already mentioned, in the present invention the resinous, polymeric substance is insoluble in water and in aqueous surfactant solution. Therefore, to dissolve the substance, a water-miscible organic solvent must be added to such a solution.

set.

Suitable polar, water-miscible solvents used in the shampoos of the invention can be used, bind e.g. monohydric alcohols such as ethanol, n-propanol, isopropanol, dihydric alcohols such as glycol, monopropylene glycol, dipropylene glycol and tripropylene glycol, iriols such as glycerol, and also polyethylene glycols (Molecular weight <400) or ethers such as monoethyl ether of ethylene glycol or diethylene glycols. The most preferred polar solvents are ethanol, n-propanol and Isopropanol

The solvent can also be water-immiscible, non-polar solvents, such as hydrocarbons, chlorinated hydrocarbons, e.g. methylene chloride, or fluorinated Hydrocarbons, such as trichlorotrifluoroethane, contain '.

The solvent is preferably contained in the shampoos of the invention in an amount of about 8-10 to about 60-70 percent, in particular 12 to 45 percent, based on the weight of the shampoo, ^m

When diluted with water the considerable amounts of organic Solvent-containing shampoos during the. When shampooing the hair, the resinous substance is deposited on the hair

If the lubricant is soluble or dispersed in the shampoo, so it is preferably in an amount of about 0.1 bic about

in particular about 1 to about 15 »
15, / ™ percent by weight, based on the weight of the shampoo. If the lubricant is insoluble and forms a separate phase, the upper limit is preferably increased to about 25 percent by weight, the preferred range is from about 4 to about 20 percent by weight.

Soluble or dispersible lubricants are, for example, organic oils, such as Beter, e.g. cetyl palmitate, n-butyl oleate, Myrietic acid or adipic acid isopropyl ester, glycol polysiloxanes or mineral oil, as well as mixtures thereof.

As already stated, the shampoos can also contain an insoluble lubricant and thus form a multiphase system, as is described in US Pat. No. 3,533,955. In these embodiments, it is necessary to add about 9 to about 2Θ percent by weight, based on the weight of the shampoo, of one or more emulsion destabilizers, for example monovalent C ₁ -C ₇ -AlkOhOIe, the monoalkyl ethers of aliphatic divalent C 1 -Cg Alcohols or C ^ -Cg dialkyl ketones to be added. These substances can also serve as organic solvents in the shampoos of the invention.

The shampoos of the invention contain one or more surfactants ("surfactants"). Salts of sulfonated and sulfated anion-active ones Surfactants are preferred, especially the sodium, magnesium and ammonium salts and the mono-, di- and triethanol

309824/1074

amine salts of sulfated G ^ pC ₂ ^ fatty alcohols and the corresponding salts of the sulfonated C ^ -C ^ -alkylaryl compounds. Typical anion-active surfactants (“detergents”) are, for example, lauryl sulfates, lauryl ether sulfates or dodecylbenzenesulfonates. . ■ . '

Suitable nonionic surfactants are, for example, fatty acid alkanolamides, such as lauric acid diethanolamide, coconut mono- and diethanolamide or lauric acid isopropanolamide and ethylene and propylene oxide condensation products hydrophobic compounds such as long-chain fatty alcohols, alkylphenols or fatty acid alkanolamides .. For the Cation-active surfactants suitable for shampoos of the invention, which may be included in minor amounts, are, for example, cetyltrimethylammonium chloride or alkyldimethylbenzylammonium chloride. Preferably the surfactant is in an amount from about -5 to about 60 percent, in particular about 5 to about 25 percent, based on the weight of the shampoo. Shampoos with lower Surfactant contents do not clean the hair well and also produce little foam, while shampoos with higher surfactant contents 'Can cause eye irritation.

The shampoos can optionally also contain about 0.2 to about 15 percent by weight, in particular 0.5 to 5 percent by weight, of one or contain more foam-boosting additives ("lather boosters") and / or stabilizers to improve the foaming power and the Increase foam stability. Examples are coconut amide, lauric acid diethanolamide, lauric acid isopropanolamide, coconut monoethanolamide, Betaines or sulfobetaines. Alkali soaps, e.g. sodium or potassium decanoate and laurate, can also be used
