Definitions

  • the invention relates to new skin care products containing fatty acid N-alkylpolyhydroxyalkylamides and their use as "synthetic barrier lipids" for the production of skin care products.
  • a balanced water balance in the individual skin layers plays an important role for the elasticity and the appearance of the skin.
  • the content of bound water is greatest in the Dennis and in the boundary layer of the epidermis near the basement membrane.
  • the skin elasticity is decisively shaped by the collagen fibrils in the Dennis, the specific conformation of the collagen being achieved by the incorporation of water molecules.
  • Destruction of the lipid barrier in the stratum corneum (SC), for example by surfactants leads to an increase in transepidermal water loss, which in turn disturbs the aqueous environment of the cells. Since the water bound in the deeper layers of the skin is only supplied via the body fluids and not from the outside it becomes clear that maintaining the barrier function of the stratum corneum is essential for the overall condition of the skin [cf. SEFriberg et al, CR 23rd CED Congress,
  • Ceramides are lipophilic amides of long-chain fatty acids, which are generally derived from sphingosine or phytosphingosine. This class of endogenous fatty substances has gained considerable importance since they, together with the corneocytes, have been recognized as key components for the construction of the lipid bilayer, ie the permeability barrier, in the stratum corneum of human skin. Ceramides have molecular weights of significantly less than 1000, so that the external site of a cosmetic formulation makes it possible to reach the site of action. The external application of ceramides leads to the restoration of the lipid barrier, which can cause the described disorders of the skin function to be counteracted [cf. R.D.Petersen, Cosm.Toll. 107, 45 (1992)].
  • R a stands for hydrogen or an unsaturated fatty acyl radical
  • z for numbers from 7 to 49
  • A for a hydroxyalkyl
  • Z for a sugar or phosphate radical
  • moisture-regulating substances include also considered long-chain, ethoxylated succinic acid derivatives.
  • the object of the invention was therefore to develop new high-performance ceramide-analog structures which are distinguished by the simplest possible synthesis. Another task was to manufacture the new pseudoceramides based on non-animal raw materials.
  • the invention relates to skin care products containing fatty acid N-alkylpolyhydroxyalkylamides of the formula (I),
  • R- ⁇ CO for an aliphatic acyl radical with 6 to 22 carbon atoms
  • R *** - for an alkyl or hydroxyalkyl radical with 4 to 22 carbon atoms
  • [Z] for a linear or branched polyhydroxyalkyl radical having 3 to 12 carbon atoms and 3 to 10 hydroxyl groups.
  • the fatty acid N-alkylpolyhydroxyalkylamides to be used in accordance with the invention strengthen the natural barrier function of the skin, strengthen the skin and protect it from drying out.
  • the substances are based on the natural skin lipids, dermatologically and ecotoxicologically harmless and can be incorporated homogeneously into the oil phase of cosmetic products. They are white or ivory-colored, odorless, hydrolysis-resistant in the range of the skin pH value and color-stable against atmospheric oxygen.
  • the invention includes the knowledge that the polyhydroxyalkylamides can be produced on the basis of vegetable fatty acids and sugar, that is to say without the undesirable use of animal raw materials.
  • the fatty acid N-alkylpolyhydroxyalkylamides are basically known substances which are usually obtained by reductive amination of a reducing sugar with a longer chain A in or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or preferably a fatty acid chloride in the presence a base (triethanolamine, sodium carbonate, etc.) can be obtained.

  • Further preferred fatty acid N-alkyl polyhydroxyalkylamides can be derived from malose and palatinose.
  • the agents according to the invention can contain the fatty acid-N-alkyl-polyhydroxyalkylamides in amounts of 1 to 30, preferably 2 to 10% by weight, based on the agents.

Furthermore, the formulations can contain water in an amount of up to 99% by weight, preferably 5 to 80% by weight.
  • Suitable carrier oils include, for example: mineral oils, vegetable oils, silicone oils, fatty acid esters, dialkyl ethers, fatty alcohols and Guerbet alcohols.
  • emulsifiers which can be used are: sorbitan esters, monoglycerides, polysorbates, polyethylene glycol mono / difatty acid esters, highly ethoxylated fatty acid esters and high molecular weight silicone compounds, such as dimethylpolysiloxanes with an average molecular weight of 10,000 to 50,000.
  • additives can be: preservatives, such as p-hydroxybenzoic acid ester; Antioxidants, such as butylhydroxytoluene, tocopherol; Humectants, such as glycerin, sorbitol, 2-pyrrolidine-5-carboxylate, dibutyl phthalate, gelatin, polyglycols with an average molecular weight of 200 to 600; Buffers such as lactic acid / TEA or lactic acid / NaOH; mild surfactants such as alkyl oligoglucosides, fatty alcohol ether sulfates, fatty acid isethionates, taurides and sarcosinates, ether carboxylic acids, sulfosuccinates, protein hy- drolysates or fatty acid condensates, sulfotriglycerides, short-chain glucamides; Phospholipids, waxes such as bees wax, ozokerite wax, par
