Description

A neutral liquid soap containing polyhydroxy fatty acid soap

technical field

The invention relates to a neutral liquid soap with a self-preservation function, in particular to a soap with a self-preservation function which contains polyhydroxy fatty acid sodium as a main raw material, and belongs to the technical field of daily chemical detergents.

Background technique

Various industrial, household or personal care soaps can be obtained through the saponification reaction of natural oils or the neutralization reaction of fatty acids derived from oils. Liquid soaps, soft soaps, soap powders and bar soaps can be prepared, which are low-cost, non-toxic and harmless , low irritation, good biodegradability, strong cleaning ability, fine and rich foam and good skin feel.

Oils in plant-derived oils rely on the outer skin of oilseeds to isolate air oxidation, isolate microbial erosion, and protect antioxidant components in oilseeds from oxidation, decomposition, hydrolysis, and degradation; oils in animal-derived oils are also protected by animal bodies. The corresponding protection is not oxidized and decomposed. However, the oil extracted from the oil is no longer protected by the epidermis and antioxidant components, and it is easy to react with oxygen, water and microorganisms to cause oxidation, hydrolysis, rancidity and other reactions to deteriorate. Soap products derived from oils also deteriorate due to the action of air, moisture and microorganisms, and the deterioration behavior of soap products containing more unsaturated components is more serious. The main methods to solve the deterioration of soap products, especially neutral liquid soap products, are to fill the packaging with nitrogen, use pumping methods to reduce the chance of product contact with air and microorganisms, and reduce or even eliminate raw materials containing unsaturated fatty acids. , adding antioxidant active ingredients or antibacterial active ingredients.

Polyhydroxy fatty acid soap shows good antibacterial performance in the range of pH4 to pH12, and can effectively inhibit the growth of common bacteria such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, Aspergillus niger, etc. grow. The challenge test shows that the block soap, powder soap and liquid soap prepared from the polyhydroxy fatty acid soap without adding any other antioxidant active ingredients and antibacterial active ingredients have good antibacterial effect.
