Definitions

  • the invention relates to the use of N-methyl-N-acylglucamines as thickeners in surfactant solutions and to cosmetic compositions containing said surfactant solutions.
  • Multi-component systems containing water or solvents such as emulsions or suspensions, are often adjusted to higher viscosities, or thickened, for economic reasons, for practical reasons or for reasons of stability.
  • increasing the viscosity of the external or internal phase of emulsions or suspensions may greatly prolong the time to separation of the components of such a system, which is reflected in an increase in storage life.
  • increasing their viscosity also improves their capacity for uniform spreading, especially on uneven surfaces.
  • the high viscosity of such preparations also offers further advantages in production, packaging, filling and storage and in transport.
  • cellulose ethers and other cellulose derivatives e.g. carboxymethylcellulose, hydroxyethylcellulose
  • gelatin starch and starch derivatives
  • sodium alginates fatty acid polyethylene glycol esters
  • agar-agar tragacanth or dextrins
  • polyvinyl alcohols for example polyvinyl alcohols, polyacrylamides, polyacrylic acid and various salts of polyacrylic acid, polyvinylpyrrolidone, polyvinyl methyl ethers, polyethylene oxides, copolymers of maleic acid anhydride and vinyl methyl ethers, and various mixtures and copolymers of the aforementioned compounds.
  • the aforementioned compounds show various disadvantages in use.
  • the cellulose derivatives or generally the materials based on natural raw materials and the resultant formulations are very susceptible to bacteria. In practical application, they are generally characterized by the formation of unpleasant, “ropy” gels. In the presence of water, fatty acid polyethylene glycol esters tend to undergo hydrolysis, and the resultant insoluble fatty acids cause undesirable clouding.

Abstract

N-methyl-N-acylglucamines are suitable as thickening agents in aqueous surfactant solutions containing one or more anionic surfactants of the group including alkyl ether sulfates and alkyl sulfates, the N-methyl-N-acylglucamines containing at least 60 wt.-% of N-methyl-N-acylglucamines that have a C12-, C14-acyl group or an unsaturated C18-acyl group and at the same time less than 5 wt.-% of N-methyl-N-acylglucamines that contain an acyl group <C12. The surfactant solutions are particularly used in cosmetic compositions.

Description

  • The invention relates to the use of N-methyl-N-acylglucamines as thickeners in surfactant solutions and to cosmetic compositions containing said surfactant solutions.
  • High requirements are imposed on cosmetic products. They should be of clear appearance, must be toxicologically and ecotoxicologically harmless, produce a pleasant sensation on the skin and have excellent rheological behavior that remains constant over a wide range of pH.
  • Multi-component systems containing water or solvents, such as emulsions or suspensions, are often adjusted to higher viscosities, or thickened, for economic reasons, for practical reasons or for reasons of stability.
  • Thus, for example increasing the viscosity of the external or internal phase of emulsions or suspensions may greatly prolong the time to separation of the components of such a system, which is reflected in an increase in storage life. With many products, increasing their viscosity also improves their capacity for uniform spreading, especially on uneven surfaces.
  • The more uniform distribution and longer time of action thus increase the efficacy. In addition to the aforementioned practical advantages, the high viscosity of such preparations also offers further advantages in production, packaging, filling and storage and in transport.
  • A great many different systems for adjusting the rheological properties of aqueous or solvent-containing systems, emulsions or suspensions are described in the technical literature. For example, cellulose ethers and other cellulose derivatives (e.g. carboxymethylcellulose, hydroxyethylcellulose), gelatin, starch and starch derivatives, sodium alginates, fatty acid polyethylene glycol esters, agar-agar, tragacanth or dextrins are known. Various materials are used as synthetic polymers, for example polyvinyl alcohols, polyacrylamides, polyacrylic acid and various salts of polyacrylic acid, polyvinylpyrrolidone, polyvinyl methyl ethers, polyethylene oxides, copolymers of maleic acid anhydride and vinyl methyl ethers, and various mixtures and copolymers of the aforementioned compounds.
  • However, the aforementioned compounds show various disadvantages in use. For example, the cellulose derivatives or generally the materials based on natural raw materials and the resultant formulations are very susceptible to bacteria. In practical application, they are generally characterized by the formation of unpleasant, “ropy” gels. In the presence of water, fatty acid polyethylene glycol esters tend to undergo hydrolysis, and the resultant insoluble fatty acids cause undesirable clouding. Thickeners of natural origin (e.g. agar-agar or tragacanth) have a greatly fluctuating composition, depending on their origin.
  • In EP-A 0 285 768, N-polyhydroxyalkyl fatty acid amides are proposed as thickeners for liquid aqueous surfactant systems. In the practical examples of this document, N-methyl coconut fatty acid glucamide is used as thickener in an ether sulfate-paraffin sulfonate mixed system.
  • Although good results are already achieved with such a system, there is still room for improvement, for example with respect to thickener performance. The task was therefore to provide thickeners for surfactant systems that display higher thickener performance relative to the known systems.
  • It was found that certain N-methyl-N-acylglucamines are particularly suitable as thickeners for surfactant systems that contain alkyl ether sulfates or alkyl sulfates, especially in combination with betaines.
  • The invention therefore relates to the use of N-methyl-N-acylglucamines as thickeners in an aqueous surfactant system containing at least one alkyl ether sulfate and/or at least one alkyl sulfate, wherein at least 60 wt % of said N-methyl-N-acylglucamines have a C12-, C14-or unsaturated C18-acyl group and the content of N-methyl-N-acylglucamines with an acyl group shorter than C12 is below 5%.
  • N-methyl-N-acylglucamines used according to the invention with C12- and C14-acyl groups and fatty acid ether sulfates or fatty acid sulfates are known from WO 92/06158 or WO 92/06162 for use in rinsing and cleaning agents. However, particular suitability of the glucamide/surfactant combinations according to the invention as thickeners especially for cosmetic compositions cannot be inferred from that.
  • The N-methyl-N-acylglucamines used according to the invention, also known as N-methyl-N-1-deoxysorbityl fatty acid amides, contain at least 60 wt % of N-methyl-N-acylglucamines that contain a C12-, C14- or an unsaturated C18-acyl group (called “C12/18—N-methyl-N-acylglucamines” hereinafter) and simultaneously contain less than 5 wt % of N-methyl-N-acylglucamines that contain a fatty acid residue <C12. The following wt % data are relative to the total amount of N-methyl-N-acylglucamines (100 wt %).
  • Saturated N-methyl-N-acylglucamines of formula (I), where the acyl residue RaCO is derived from lauric acid, myristic acid, oleic acid, linoleic acid or linolenic acid, are especially preferred as component a):

  • Condensation products of ethylene oxide with a hydrophobic basis, formed by condensation of propylene oxide with propylene glycol. The hydrophobic moiety of these compounds preferably has a molecular weight between 1500 and 1800. Addition of ethylene oxide to this hydrophobic moiety leads to an improvement in water solubility. The product is liquid up to a polyoxyethylene content of approx. 50% of the total weight of the condensation product, which corresponds to condensation with up to approx. 40 mol ethylene oxide. Commercially available examples in this product class are the Pluronic® brands from BASF and the Genapol® PF brands from Clariant.
  • Condensation products of ethylene oxide with a reaction product of propylene oxide and ethylenediamine.

  • The amount of the nonionic surfactants in the compositions according to the invention may be up to 10 wt %, relative to the total weight of the finished compositions.
  • Furthermore, the compositions according to the invention may contain amphoteric surfactants. These can be described as derivatives of long-chain secondary or tertiary amines, which have an alkyl group with 8 to 18 carbon atoms and in which another group is substituted with an anionic group, which imparts the water solubility, for instance with a carboxyl, sulfate or sulfonate group. Preferred amphoteric surfactants are N—(C12-C18-alkyl-β-aminopropionates and N—(C12-C18)-alkyl-β-iminodipropionates as alkali- and mono-, di- and trialkylammonium salts. Other suitable surfactants also include amine oxides. These are oxides of tertiary amines with a long-chain group of from 8 to 18 carbon atoms and two generally short-chain alkyl groups with 1 to 4 carbon atoms. For example the C10- to C18-alkyldimethylamine oxides, fatty acid amidoalkyl-dimethylamine oxide are preferred in this case.
  • The amount of the amphoteric surfactants in the compositions according to the invention may be up to 10 wt %, relative to the total weight of the finished compositions.

  • Formulation examples 1, 2 and 3 according to the invention required by far the lowest salt concentrations relative to the comparative examples not according to the invention. This is advantageous with respect to the dermal and mucosal compatibility of the cosmetic formulations. In particular, it can be seen from example 2 that a synergy in thickening develops when glucamides with chain length C12/14 and unsaturated C18 components are combined. In contrast, the products derived from coconut oil and corresponding to EP 0 285 768 (comparative examples 1 and 6) do not possess thickening performance corresponding to examples 1-3. Comparative example 3 shows that the thickening performance of saturated C16/18 glucamides does not match the compositions according to the invention.
