AI Technical Summary

Technical Problem

Retinol is difficult to stabilize, especially in high quantities, due to its susceptibility to degradation, which complicates its incorporation into cosmetic compositions without deterioration over time.

Method used

Development of stable cosmetic compositions that include high quantities of retinol by using a specific formulation including retinol, non-ionic emulsifiers, fatty alcohols, fatty compounds, thickening polymers, and water, which forms an emulsion of oil in water, thereby preserving retinol and maintaining its effectiveness.

Benefits of technology

The cosmetic compositions effectively preserve retinol, allowing for high concentrations to be maintained, which promotes collagen and elastin production, reduces fine lines and wrinkles, firms the skin, prevents and treats acne, decreases melanin development, and improves skin complexion.

Abstract

COSMETIC COMPOSITIONS CONTAINING HIGH AMOUNTS OF RETINOL This disclosure relates to stable cosmetic compositions containing high amounts of retinol. The cosmetic compositions further include, among other things, a plurality of nonionic emulsifiers, fatty alcohols, fatty compounds, thickening polymers, and water. Processes for solubilizing high amounts of retinol and processes for treating the skin with the cosmetic compositions are also described. Processes for stabilizing cosmetic compositions containing high amounts of retinol and processes for preserving high amounts of retinol are also described. This disclosure also describes processes for treating the skin with the cosmetic compositions. Figure for the abstract: none.
