Science
Mechanism of Action
This end-capped homopolymer creates a lightweight, protective film on the skin's surface. The dimethiconol component forms a smooth, non-greasy barrier that critically minimizes transepidermal water loss (TEWL), thereby locking in moisture. Concurrently, the kokum butter-derived fatty acids supply essential exogenous lipids, which integrate into the stratum corneum. This dual action improves skin barrier properties, fills intercellular gaps within corneocyte clusters to boost hydration, and offers a degree of protection against environmental inflammation.

Stability
This ingredient is characterized by its oil solubility. While no specific optimal pH range for stability has been identified, its component, dimethiconol, is known to be insoluble in water but readily soluble in various oil-based solvents, indicating robust performance within lipid systems.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly assessed Dimethiconol Kokum Butterate and related silicone compounds, concluding they are safe under current cosmetic use practices. The panel's determination is based on the negligible dermal absorption of these ingredients, which alleviates concerns regarding potential reproductive toxicity, developmental toxicity, or carcinogenicity. Furthermore, the FDA considers dimethiconol safe for cosmetic applications.
