Application of Anionic Phosphorus Derivatives of Alkyl Polyglucosides for the Production of Sustainable and Mild Body Wash Cosmetics

This paper explores the possibility of using phosphorus derivatives of alkyl polyglucosides with varying alkyl chain lengths (C4, C8, C10, C12), obtained from natural raw materials, in the production of mild and eco-friendly body wash cosmetics, as examples of sustainable products. The central assumption was that partial replacement of sodium laureth sulfate, which is widely used as the primary washing compound in such products, with this type of anionic surfactants would result in products with improved safety-in-use—in terms of their mild effect on the skin—and more environmentally friendly characteristics. Prototypical products formulated with phosphorus derivatives of alkyl polyglucosides were found to have significantly lower zein number values and produce a smaller increase in the pH of bovine serum albumin solution compared to a reference sample formulated without these compounds. The findings suggest a marked reduction in the skin irritation effect of cosmetics. In addition, the application of this type of anionic surfactants in body wash products significantly decreases their ability to emulsify fats. Consequently, as demonstrated in corneometric tests, the skin drying effect produced by the washing process is significantly reduced.
