AI Technical Summary

Technical Problem

The crystallization of vanillin and other lipophilic compounds in cosmetic preparations containing UV light protection filters leads to reduced sensory properties and UV protection, especially when combined with Bis-Ethylhexyloxyphenol methoxyphenyl Triazine, and C12-15 alkyl benzoate accelerates vanillin precipitation.

Method used

A cosmetic preparation combining 4-hydroxy-3-methoxybenzaldehyde (vanillin), Bis-Ethylhexyloxyphenol methoxyphenyl Triazine, dibutyl adipate, and/or butylene glycol dicaprylate/dicaprate, with specific concentration ranges, prevents crystallization and maintains UV protection.

Benefits of technology

The combination effectively prevents crystallization and maintains UV protection, ensuring improved sensory properties and stability of the cosmetic formulation.
