INCI Name: Silica Dimethyl Silylate
Appearance: Ultrafine white powder
Solubility: Dispersible in oils, silicones, esters (not water-soluble)
Usage Rate: 0.5% – 10%
Function: Thickener, oil gelling agent, suspension aid, stabilizer
Silica Dimethyl Silylate is a fumed silica treated with dimethyldichlorosilane to enhance oil compatibility and provide thickening, suspension, and structuring properties in anhydrous or low-water formulations. It is commonly used to create clear oil gels, improve pigment suspension, and stabilize stick or balm textures.
Silica Dimethyl Silylate is a surface-treated, hydrophobic silica powder used to thicken and stabilize oils, esters, and silicones. It creates a 3D network that helps control viscosity, improve structure, and suspend pigments or actives in oil-based systems. It is highly effective in transparent or solid anhydrous formulations where flow and spread must be carefully controlled.
Disperse slowly into oils or silicones under moderate to high shear. Avoid introducing water. Best used in combination with low-viscosity carriers for gel systems or stick formats.
Pre-mix with oil phase ingredients and stir until fully dispersed. May require homogenization or high shear mixing.
