DIMETHOXYSILYL ETHYLENEDIAMINOPROPYL DIMETHICONE.

Valuable CAS 71750-80-6 / HAIR CONDITIONING, SURFACTANT - EMULSIFYING

DIMETHOXYSILYL ETHYLENEDIAMINOPROPYL DIMETHICONE is a sophisticated modified silicone polymer, expertly engineered to function as a conditioning agent and emollient. It forms a protective, non-occlusive barrier on the skin's surface, effectively minimizing transepidermal water loss. This action enhances skin hydration and imparts a visibly smoother, plumper appearance while offering a degree of protection against environmental stressors.

Science

Mechanism of Action

This advanced silicone derivative operates by creating a fine, breathable film on the skin's epidermal layer. This barrier is crucial for optimizing moisture retention, thus boosting skin hydration and acting as a physical shield against external irritants. Through its film-forming and lubricating capabilities, it also visibly smooths superficial fine lines and uneven textures, contributing to a more refined and supple skin feel. Additionally, it improves the texture and spreadability of cosmetic formulations, demonstrating excellent emulsifying and dispersing properties.

Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel affirmed this ingredient as 'safe as used' in cosmetic products, a conclusion maintained through a 2020 re-evaluation. Its large molecular weight is considered a primary factor preventing significant skin absorption. While its parent compound, Dimethicone, holds FDA approval as a skin protectant at concentrations from 1% to 30%, specific concentration limits for this derivative are not provided by CIR.
