Organo-Modified Silicone

  • Silicones
  • CAS Withheld

Organo-Modified Silicone (CAS Withheld) appears in 2 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

Organo-functional silicone conditioning agent with low acute toxicity. No GHS classification at product concentrations. No Prop 65 listing. CAS number withheld as proprietary.

Organo-modified silicone is a proprietary organo-functional silicone ingredient used in leather conditioners to provide surface protection, enhanced slip, and a durable conditioning film on leather fibers. The organic modification (via reaction with alcohols, amines, or polyethers) improves compatibility with the water-based emulsion system and enables the silicone to bond more effectively with the leather surface than unmodified dimethicone.

The CAS number is withheld as a trade secret in the safety data sheet. Silicone-class ingredients are generally inert, with low acute toxicity and low environmental mobility. Not readily biodegradable but low bioaccumulation potential due to the polymer structure.
