CARBOXYDECYL TRISILOXANE.

Valuable CAS - / SKIN CONDITIONING, SOOTHING

An advanced, carboxyl-modified silicone fluid that combines the breathability of traditional silicones with the nourishing profile of organic oils. It serves as a high-performance emollient that bridges the gap between synthetic slip and biological compatibility, delivering a refined, non-greasy finish.

Science

It functions by depositing a vapor-permeable, non-occlusive film over the stratum corneum, which physically mitigates transepidermal water loss while allowing normal cutaneous respiration. The unique addition of carboxyl groups allows it to stabilize pigment dispersions and seamlessly integrate with botanical lipids, enhancing the uniform distribution of active ingredients across the skin's micro-relief.
