Water-based formulations increase shipping weight and require preservatives, which is mitigated by stabilizing high-concentration anionic surfactants within a solid organic filler network. This architecture enables plastic-free cosmetic packaging while maintaining rapid dissolution during consumer use.
Conventional aqueous surfactant systems suffer from microbial degradation, chemical instability, and high shipping volumes. Concentrating active ingredients into a stable anhydrous solid reduces transport costs and eliminates the need for preservatives.
