Abstract

The proposal is for novel cosmetic preparations for use in the field of hair and skin care, containing (a) esterquats and (b1) sorbitane esters, (b2) polyol poly-12-hydroxy stearates and/or (b3) glycerides and possibly (c1) alkyl and/or alkenyl oligoglycosides and/or (c2) fatty acid-N-alkyl polyhydroxyalkyl amides. The agents are distinguished by improved softness in the hair and a particularly pleasant feel to the skin.

Description

Cosmetic preparations based on cationic and nonionic surfactants

Field of the Invention

The invention relates to cosmetic preparations with improved sensory properties for use in skin and hair care, containing esterquats and selected surfactants in binary or ternary mixtures.

State of the art

Esterquats are cationic surfactants which, because of their excellent ecotoxicological properties, are becoming increasingly important both for the area of fabric softeners and for cosmetic applications. Overviews on this topic have been published, for example, by R.Puchta et al. in tens. Surf. Det., 30, 186 (1993), M.Brock in Tens. Surf. Det. 30, 394 (1993), R. Lagerman et al. in J. Am. Oil. Chem. Soc, 71, 97 (1994) and I. Shapiro et al. in Cosm.Toil. 109, 77 (1994) appeared.

In cosmetic preparations, esterquats, preferably together with fatty alcohols, are used to achieve a pleasant, soft skin and hair feeling. They can be contained in emulsions and lotions for skin care as well as in surfactants such as shampoos, shower baths, rinses, conditioners and the like for hair care. The disadvantage here, however, is that the desired soft feel of the skin and hair is perceived as dull and dry, while the consumer desires a soft, smooth feel. The object of the present invention is therefore to add ester quats in such a way that low-viscosity, storage-stable concentrates result which have the desired sensor properties and are self-emulsifying in water.

Description of the invention

The invention relates to cosmetic preparations containing

(a) Esterquats and

(b1) sorbitan esters,

(b2) polyol poly-12-hydroxystearate and / or

(b3) glycerides and optionally

(d) alkyl and / or alkenyl oligoglycosides and / or

(c2) Fatty acid N-alkyl polyhydroxyalkyl amides.

Surprisingly, it was found that the addition of substances which form component (b) significantly improve the softness of esterquats and their skin-sensory properties. A further increase in the properties can be achieved if the further component (c) is added to the mixtures of ester quats with the substances of group (b). The resulting concentrates are anhydrous, low-viscosity, stable in storage and self-emulsifying when introduced into aqueous phases.

Esterquats

The term “esterquats” is generally understood to mean quaternized fatty acid triethanol amine ester salts. These are known substances which can be obtained by the relevant methods of preparative organic chemistry. In this connection, reference is made to the international patent application WO 91 / 01295 (Henkel), according to which triethanolamine is partially esterified with fatty acids in the presence of hypophosphorous acid, air is passed through and then quaternized with dimethyl sulfate or ethylene oxide. The quaternized fatty acid triethanolamine ester salts follow the formula (I)

in the R'CO for an acyl radical with 6 to 22 carbon atoms, R ² and R ³ independently of one another for hydrogen or R ¹ CO, R ⁴ for an alkyl radical with 1 to 4 carbon atoms or a (CH ₂ CH ₂ 0) _q H- Group, m, n and p in total for 0 or numbers from 1 to 12, q for numbers from 1 to 12 and X for halide, alkyl sulfate or alkyl phosphate. Typical examples of ester quats that can be used in the sense of the invention are products based on caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, isostearic acid, stearic acid, oleic acid, elaidic acid, arachic acid, behenic acid and erucic acid and theirs Technical blends, such as those that occur when natural fats and oils are split. Technical Ci2 / i8 coconut fatty acids and in particular partially hardened Ciβ / iβ tallow or palm fatty acids as well as elaidic acid-rich Ci6 / 18 fatty acid cuts are preferably used. The fatty acids and the triethanolamine can be used in a molar ratio of 1.1: 1 to 3: 1 to produce the quaternized esters. With regard to the application properties of the ester quats, an application ratio of 1.2: 1 to 2.2: 1, preferably 1.5: 1 to 1.9: 1 has proven to be particularly advantageous. The preferred esterquats are technical mixtures of mono-, di- and triesters with an average degree of esterification of 1.5 to 1.9 and are derived from technical C16 / "tallow or palm fatty acid (iodine number 0 to 40). From an application point of view, quaternized fatty acid triethanolamine ester salts of the formula (I) have proven to be particularly advantageous in which R ¹ CO for an acyl radical having 16 to 18 carbon atoms, R ² for R ¹ CO, R ³ for hydrogen, R ⁴ for a methyl group, m , n and p is 0 and X is methyl sulfate.

In addition to the quaternized fatty acid triethanolamine ester salts, quaternized ester salts of fatty acids with diethanolalkylamines of the formula (II) are also suitable as ester quats.

With regard to the selection of the preferred fatty acids and the optimal degree of esterification, the examples given for (I) also apply to the esterquats of the formulas (II) and (III). The esterquats usually come on the market in the form of 50 to 90% strength by weight alcoholic solutions, which can be diluted with water if required.

Sorbitan esters

Sorbitan esters which form component (b1) are known nonionic surfactants which are usually obtained by esterifying sorbitan with fatty acids. Typical sorbitan esters follow the formula (IV) in which

R ⁸ CO represents an aliphatic, saturated or unsaturated acyl radical having 6 to 22 and preferably 12 to 18 carbon atoms. Formula (IV) represents a sorbitan monoester; however, the esters can also be present as sesquiesters, diesters, triesters or their technical mixtures. Typical Examples are the corresponding esters of sorbitan with lauric acid, palmitic acid, stearic acid, isostearic acid or oleic acid.

Polyol poly-12-hydroxystearate

The polyol poly-12-hydroxystearates which form component (b2) are known substances which are sold, for example, under the Dehymuls® PGPH brand [cf. DE-A1 44 20

516], The polyol component of the emulsifiers can be derived from substances which have at least two, preferably 3 to 12 and in particular 3 to 8 hydroxyl groups and 2 to 12 carbon atoms. Typical examples are:

• glycerin and polyglycerin;

Alkylene glycols, such as, for example, ethylene glycol, diethylene glycol, propylene glycol;

• Methyl compounds, such as in particular trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol and dipentaerythritol;

Alkyl oligoglucosides with 1 to 22, preferably 1 to 8 and in particular 1 to 4 carbons in the alkyl radical, such as methyl and butyl glucoside;

Sugar alcohols with 5 to 12 carbon atoms, such as sorbitol or mannitol,

• Sugar with 5 to 12 carbon atoms, such as glucose or sucrose;

Aminosugars such as glucamine.

Among the emulsifiers to be used according to the invention, reaction products based on polyglycerol are of particular importance because of their excellent performance properties. The use of selected polyglycerols which have the following homolog distribution has proven to be particularly advantageous (the preferred ranges are given in brackets):

Glycerin 5 to 35 (15 to 30) wt%

Diglycerols 15 to 40 (20 to 32) wt%

Triglycerols 10 to 35 (15 to 25)% by weight

Tetraglycerols 5 to 20 (8 to 15) wt%

Pentaglycerols 2 to 10 (3 to 8) wt%

Oligoglycerols ad 100% by weight Glvceride

As component (b3) are esters of glycerol with one, two or three fatty acids with 6 to 22 and preferably 12 to 18 carbon atoms. Typical examples are vegetable oils, such as almond oil, or technical partial glycerides such as, for example, monoglycerides based on lauric acid, palmitic acid, stearic acid, isostearic acid and / or oleic acid. Technical partial glycerides of fatty acids with 12 to 18 carbon atoms are preferably used.

Alkyl and / or alkenyl oligonucleotides

Alkyl and alkenyl oligoglycosides which form component (d) are known nonionic surfactants which follow the formula (V)

R ⁹ 0- [G] _p (V)

in which R ^{9 represents} an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G represents a sugar radical having 5 or 6 carbon atoms and p represents numbers from 1 to 10. They can be obtained using the relevant preparative organic chemistry processes. As a representative of the extensive literature, reference is made here to the documents EP-A1 0 301 298 and WO 90/03977.

The alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (V) indicates the degree of oligomerization (DP), i.e. H. the distribution of mono- and oligoglycosides is present and stands for a number between 1 and 10. While p must always be an integer in a given compound and can in particular assume the values p = 1 to 6, the value p is for a specific alkyl oligoglycoside an analytically calculated quantity, which usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4.

The alkyl or alkenyl radical R ⁹ can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capro alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained from Roelen's oxosynthesis, for example in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes. Alkyl oligoglucosides of chain length Cβ-C10 (DP = 1 to 3) are preferred, which are obtained as a preliminary step in the separation of technical Cβ-Ciβ-coconut fatty alcohol by distillation and contaminated with a proportion of less than 6% by weight of C ₂ alcohol can be as well as alkyl oligoglucosides based on technical Cg / n-oxo alcohols {DP = 1 to 3). The alkyl or alkenyl radical R ⁹ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palm oleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and the technical mixtures described above, which can be obtained as well as their technical mixtures. Alkyl oligoglucosides based on hydrogenated Ci∑yu coconut alcohol with a DP of 1 to 3 are preferred.

Fatty acid N-alkyl polyhydroxyalkylamides

Fatty acid N-alkylpolyhydroxyalkylamides which are suitable as component (c2) are nonionic surfactants which follow the formula (VI)

IR ¹ ° CO-N- [Z] (VI)

in which R ¹⁰ CO for an aliphatic acyl radical with 6 to 22 carbon atoms, R ¹¹ for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 12 carbon atoms and 3 to 10 hydroxyl groups stands. The fatty acid N-alkyl polyhydroxyalkylamides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride. With regard to the processes for their production, reference is made to US Pat. Nos. 1,985,424, 2,016,962 and 2,703,798 and international patent application WO 92/06984. An overview of this topic by H.Kelkenberg can be found in Tens.Surf.Deterg. 25, 8 (1988). The fatty acid N-alkylpolyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, in particular from glucose. The preferred fatty acid N-alkyl polyhydroxyalkylamides are therefore fatty acid N-alkylglucamides, as represented by the formula (VII):
