DD150759A1 - CLEAR, WATER-BASED COSMETIC CLEANING AGENTS - Google Patents

Abstract

Cosmetic cleansers with a content of aqueous surfactants and lipids in the form of clear and stable solutions are achieved. This is achieved by a content of 40 to 89% of aqueous anionic surfactants, 1 to 50% of nonionic surfactants, optionally mixed with monohydric or polyhydric alcohols or glycol ethers, and 2 to 35% of lipids.

Description

Title of the invention

Clear, hydrous cosmetic cleanser

Field of application of the invention

The invention relates to clear, aqueous cosmetic cleaners containing surfactants, lipids and other additives.

Characteristic of the known technical solutions

It is known that cosmetic cleansers such as e.g. Hand and body cleansers, bubble baths and washes, anionic surfactants. However, these products degrade the skin more or less. It is therefore known that such surfactant solutions can be added to lipids to reduce the degreasing of the skin or hair. The amounts of water-insoluble lipids that can be clearly dissolved in aqueous surfactant solutions are very low, so that only a small effect is achieved. An increase in the lipid levels leads to turbidity of the mixtures, which changes into a phase separation after prolonged standing.

There are already known liquid cosmetic detergents containing water-insoluble lipids whose solutions are clearly and virtually unlimited stability (DE-AS 1 467 576). They contain n-alkylbenzenesulfonate, paraffin oil, fatty acid amide polyglycol ether, fatty alcohol polyglycol ether, perfume, vitamin extract,

Glycol or glycol ether and water. In addition, they contain sodium or potassium chloride to give clear mixtures. The preparation is carried out first by mixing the surfactants mentioned, lipids and solvents. The result is a cloudy mixture. The salt is then added to this turbid mixture. By vigorous stirring then creates a clear solution.

The disadvantage here is that the clear solution can only be brought about by the addition of an alien inorganic substance, which also also requires an additional process step. Moreover, this solution is applicable only to a few special cases.

Object of the invention

The aim of the invention are clear, water-containing cosmetic cleaning products with moisturizing effect, which are phased-free producible and virtually indefinitely durable.

Explanation d the essence of the invention

It was the object of developing cosmetic cleansing agents as clear and stable solutions which contain, as refatting components, little or non-polar, water-insoluble lipids, are miscible with water and do not require additionally inorganic foreign substances to clarify them.

This object is achieved in that the mixtures contain 40-98 ~ ß> aqueous anionic surfactant solution, 1-50 "/» nonionic surfactants, optionally in admixture with mono- or polyhydric alcohols or glycol ethers, and 2-35 f ^j lipids.

The anionic and nonionic surfactants and the lipids, alcohols and glycol ethers can be defined individual substances or defined substance mixtures.

Suitable anionic surfactants are preferably alkyl ether sulfates, alkyl sulfates, alkyl sulfonates, alkylbenzenesulfonates, fatty alcohol

polyglycol ether sulfosuccinates and fatty acid-protein condensation products in embossing.

The anionic surfactants may be in admixture with amphoteric surfactants or amine oxides.

Nonionic surfactants are preferably fatty acid alkylolamides, sorbitan fatty acid esters, ethoxylated fatty alcohols and ethoxylated alkylphenols.

The lipids preferably used are synthetic fatty acid esters, paraffin hydrocarbons or vegetable or animal oils or fats.

The ratio of lipid to nonionic surfactant is a maximum of 70 to 30.

The mixtures according to the invention may contain perfume oils, preservatives, dyes, active ingredients or other additives as required.

The preparation of the cosmetic cleansing compositions according to the invention is advantageously carried out by mixing the lipids and nonionic surfactants and optionally the monohydric or polyhydric alcohols and then adding the aqueous anionic surfactant solutions. After the mixture has become clear with stirring, water may optionally be added.
