Description

The present invention relates to a process for the preparation of acyl lactylates containing biologically important cations and / or trace elements from C8-C24 saturated and / or saturated and / or unsaturated fatty acids, lactic acids and cation-providing basic compounds. The present invention also relates to cosmetic compositions comprising acyl lactylates obtained by the process of the invention.

The process according to the invention is carried out in such a way that 0.2-4 moles of lactic acid, with stirring at 20-90 ° C, are equivalent to 0.05-1.5 atomic mass equivalents of one or more metals such as calcium, magnesium, sodium and potassium. trace elements such as copper, nickel, molybdenum oxide, hydroxide, bicarbonate and / or carbonate or other salt are added, then, after cessation of foaming, 1 mole of fatty acid or fatty acid mixture and, occasionally, viscosity reducing and solubility additive, In this case, the reaction mixture is stirred at 150-240 ° C with bubbling of inert gas, then the resulting water is distilled off, stirring is continued for 0.5-6 hours at the above temperature, and the resulting acyl lactylate is cooled and optionally bleached with hydrogen peroxide. .

The use of acyl lactylates in the cosmetic industry is known. It is preferred as an emulsifier in creams, as a lotion in lotions for body lotions, as an emulsion stabilizer, conditioner, viscosity enhancer, shampoo conditioner, foam stabilizer, skin-friendly anionic surfactant.

Such applications, together with composition examples, are described by RÓBERT R. LINTON in: DRUG AND COSMETICS INDUSTRIE 1984.5. (52-57); LJ MURPHY; F.R.BAIOCCHI DRUG AND COSMETICS 1978.5. (35-45) and (129-130); F. BAIOCHI, D. JENNINGS, A.J. DEL VECCHIO; COSMETICS AND TOILETRIES 1975.9. (31-34); and L.J. MURPHY, F.R. BAIOCCHI: COSMETICS AND TOILETRIES

1980.4 (43-45).

All articles emphasize the wide applicability and good physico-chemical properties of acyl lactylates. The physiological and physiological effects of the acyl lactylates used are not mentioned, and probably no such effects have been observed.

They only indicate the antibacterial activity of caprylic lactylate, which is why they are recommended for use in the food industry, such as bakery.

It is an object of the present invention to have not only a physical, physico-chemical role in the cosmetic industry but also, by attaching biologically important cations and / or trace elements by organic chemical bond, to advantageous biological properties that have a beneficial effect on the physiological and other properties of cosmetics. .

It is a further object of our study to develop technologies for the preparation of such acyl lactylates containing biologically important cations and / or trace elements.

In our experiment we have found that although many cosmetic products have good moisturizing and regenerating effect, they are not suitable for biological regeneration of the skin. Trace elements play a very small role in the functioning of the living organism, and their deficiency also leads to lesions on the skin surface. If the trace elements can be incorporated into a cosmetic formulation chemically bound to a suitable organic substance, the highly absorbent carrier will also deliver them to the skin. Such good carriers have been found to be acyl lactylates, which are tenside-type cosmetic excipients with good absorbency and a number of advantageous properties. We chose the composition of curative, thermal and mineral waters as therapeutic, biologically important cation compositions. Based on the test results, not only the solutes of these aqueous solutions of natural origin, either in their natural or concentrated state, but also correspondingly "blended" or mixed mixtures can be used to prepare acyl lactylates. Another task was to develop the technology for the production of acyl lactylate, in particular because of the need to react large quantities of various inorganic materials.

During the preparation of the acyl lactylates, our experiments have shown that the optimum reaction temperature, reaction time and melting point and viscosity of the lactates formed during the first reaction step are different. To overcome viscosity difficulties (poor miscibility), viscosity reducing agents (polyethoxylated fatty alcohols, paraffin oil, various natural oils, etc.) were added to the reaction mixture, which would otherwise emulsify, grease and so on. impact.

The acyl lactylates thus prepared have the expected beneficial biological properties as adjuvants in cosmetic formulations.

In accordance with the object of the present invention, the process for the preparation of acyl lactylates containing biologically important cations and / or trace elements from C 8 -C 24 saturated and / or unsaturated fatty acids, lactic acid and cation-providing basic compounds is carried out in an amount of 0.2 to 4 moles. lactic acid is stirred at a temperature of 20-90 ° C with a mixture containing from 0.05 to 1.5 equivalents of one or more oxides, hydroxides, bicarbonates and / or carbonates or other salts of one or more metals.

After the foaming ceases, 1 mole of fatty acid or fatty acid mixture and occasionally viscosity reducing additives are added. Under stirring and, if desired, bubbling gas, the reaction mixture is heated to 150-240 ° C, the distillation water is removed, and the stirring and temperature is maintained for 0.5-6 hours. The resulting acyl lactylate is used in cosmetic formulations after refrigeration and optional bleaching, if desired, or directly.

A further feature of our process is that metal oxide, (hydroxide, bicarbonate) carbonate or other

The compound containing natural medicinal and mineral waters and / or thermal waters in their natural and / or concentrated state and / or their evaporated residues and / or their mixtures in a proportion or similar proportions are used as the compound containing.

The process further comprises using as fatty acids co-3, ω-6 unsaturated fatty acids and / or mixtures thereof, preferably linoleic acid, α-, ω-, linolenic acid, arachidonic acid, sunflower oil and / or borage oil.

The acyl lactylates thus obtained are used in an amount of from 1 to 15% by weight, preferably as an emulsifying foam stabilizer in cosmetic compositions.

An advantage of the process according to the invention is the preparation of acyl lactylates containing compounds of biological importance in organic bond. Acyl lactylates are surfactants used in the cosmetics industry, having good absorption properties, which are not altered by the addition of cations. Thus, the bioavailable trace elements can be effectively delivered to the skin using a highly absorbable, versatile cosmetic excipient.

Likewise, acyl lactylates having a biologically advantageous property are prepared when the cations are prepared not only from certain trace elements, but also from their highly medicinal compositions, such as solutes of mineral waters, thermal waters, thermal waters.

A further advantage of the process is that the biologically important solutes can be incorporated into cosmetic products in concentrations up to hundreds of times their natural occurrence. Moreover, trace elements are also concentrated and present in the same way, which otherwise occur only in trace concentrations below detectable levels. Acyl lactylates of the unsaturated fatty acids or mixtures thereof and preparations containing them have similar physiological properties.

The economic advantage of the process according to the invention is primarily the physiological effect of the materials used. However, its significance can be increased by the fact that the production technology is suitable for large-scale, economical implementation and therefore it can be widely used in preparations.

Make:

The lactylates are thawed and coconut fatty acid diethanolamide and Na-lauryl sulfate are added slowly with stirring.

Then we add the water, the plant extract, the preservative, the fragrance and finally the alkyl amidobetaine.

After resting, fill it.
