Stearyl dimethicone

Stearyl dimethicone (CAS 67762-83-8) is a silicone polymer modified with stearyl (C18) alkyl groups, combining silicone surface-slip with long-chain fatty emollience.

Where is Stearyl dimethicone used?

• Personal care: emulsifier, conditioning agent and surface modifier
• Skin and hair care: smooth, non-greasy feel and improved spreadability in creams, lotions and leave-on conditioners
• Color cosmetics: pigment dispersion and uniform coverage in foundations and pressed powders
• Textile finishing: soft-hand effects and fabric slip without compromising breathability
• Coatings and sealants: surface-active modifier for substrate wetting
• It also reduces surface tension in silicone-based systems.

Commercial specifications

• Cosmetic grade is the dominant commercial form, conforming to standard industry purity expectations for personal care
