Silica dimethyl silylate did not cause any developmental toxicity to rats up to 3.8 g/kg/d, rabbits up to 1600 mg/kg, hamsters up to 1600 mg/kg, or mice up to 1340 mg/kg. There were no reproductive effects in rats up to 509 mg/kg/d.

General safety info about Trimethylsiloxysilicate from CIR

The CIR Expert Panel assessed the safety of silica silylate, silica dimethyl silylate, trimethylsiloxysilicate, and trifluoropropyldimethyl/trimethylsiloxysilicate as used in cosmetics. The silylates and surface modified siloxysilicates included in this safety assessment have a number of functions in cosmetic formulations, including use as antifoaming agents, anti-caking agents, bulking agents, binders, skin-conditioning agents-emollient, skin-conditioning agents-occlusive, slip modifiers, suspension agentsnonsurfactant, and viscosity increasing agents-nonaqueous. The Panel reviewed available animal and clinical data, as well as information from previous CIR reports on silica. The Panel concluded that silylates and surface modified siloxysilicates are… [to be determined at the Panel meeting].
