Abstract

Skin Cleanser & Cleanser containing an anhydrous mixture formed 10 to 25% alkali-based reducing agents dithionic acid salts, 2 to 12% surfactants, 20 to 50% oily constituents as mineral, animal or vegetable or synthetic oils, 25 to 50% abrasive components based on inorganic materials, 1 to 10% triethanolamine and optionally 0.5 to 3% fragrances. Highly efficient relatively low detergent aggressiveness to the skin.

Description

SUMMARY OF THE INVENTION The present invention provides a composition for cleaning and protecting the skin, moderately and heavily soiled, particularly on the hands, useful for washing with water. It is based on a mixture of reducing agents, surfactants, protective oil components, abrasives and fragrances. Many workers, especially in the field of production and processing of organic dyes, regularly contaminate the skin of the hands with these dyes, the removal of which by conventional soap and detergent compositions is very difficult and inadequate and is usually solved using drastic oxidizing or reducing agents.

It has now been found that the compositions according to the invention can be advantageously used for this purpose, wherein dithionic acid derivatives or alkali salts thereof which have a sufficiently long-term stability in the anhydrous medium and thus allow good shelf-life of the composition are excellent. Suitable surfactants to be used in the formulations of the composition according to the invention are, in particular, anhydrous preparations, preferably alkaline soaps, alkyl sulfates, alkylbenzenesulfonates, sulfosuccinates, fatty alcohol polyglycol ethers, fatty acid polyglycol ethers, alkylphenol polyglycol ethers, or ethylene glycols. However, the surfactants used must, in addition to good washing effects, also have sufficient activity to emulsify protective oil components such as vegetable, animal, white petroleum and synthetic oils. Abrasives such as various granular quartz sands, amorphous and crystalline silica-based materials, ground or precipitated limestone, or other natural materials further enhance the washing performance of the present invention. The composition according to the invention can be finalized by the addition of fragrances,

The advantage of the formulation according to the invention is its relatively low skin aggressiveness, as demonstrated by the evaluating epicular test.

242,641 those at 24.48 and 72 hours. The composition is highly effective in the field of difficult to remove impurities such as azo dyes or anthraquinone dyes.

The skin cleansing and protection composition according to the invention consists of an anhydrous mixture of 10 to 25% reducing agents based on alkali dithionic acid salts, up to 12% surfactants, 20 to 50% oily components, 25 to 50% abrasive impurities, 1 to 10% triethanolamine and 0.5 to 3% fragrance.

The invention is further illustrated by, but not limited to, examples.

Example 1

At a temperature of about 40 ° C, 1 part of C 12 to C 24 oxyethylene fatty alcohols, 20 to 30 ethylene oxide units, 2.5 parts of mink oil, 1 part of medical petrolatum oil, 0.5 parts of triethanolamine, 2 parts anhydrous sodium dithionite, with 3 parts silica sand turns 0.01 to 0.1 mm, with 0.05 parts perfume. After cooling, the homogeneous mixture can be filled into user containers and used for the above-mentioned purpose, in particular for removing hard-to-remove anthraquinone dyes and reactive dyes from the skin of the hands.

Example 2

At a temperature of about 40 to 45 ° C, 0.8 parts of oxyethylated C 12 to C 24 fatty alcohols with 20 to 30 ethylene oxide units are mixed with 0.1 parts of oxyethylated nonylphenol with 10 to 11 ethylene oxide units with 1 part sunflower oil, parts of white petrolatum oil, 0.1 parts of triethanolamine with 0.8 parts of anhydrous sodium dithionite,

3.5 parts of precipitated calcium carbonate and 0.1 parts of perfume. The homogeneous mixture, when filled into user containers, can be used to remove azo dyes from the skin of the hands.

Example 3

At a temperature of about 45 ° C, 10% of medical grade 3 242 641 linseed oil and 30% polypropylene oil, 20% anhydrous sodium dithionite, 0.24% lanolin, 1.22% stearin,

3.2% oxyethylated C 12 -C 20 fatty alcohols with 20 to 30 ethylene oxide units, 2.68% elaine, 5.3% triethanolamine, 0.6% polyethylene glycol, 0.85% propylene glycol, 6.15% oxide silica, 10% sand of 0.01 to 0.1 mm grain, 1% precipitated calcium carbonate and 1% perfume. The homogeneous mixture can be immediately filled into user packaging and used as a universal, non-toxic agent for removing colored substances from the skin of the hands. In the examples, parts are by weight.
