Alkyl Silicone Resin (proprietary)

  • Silicones
  • CAS proprietary
  • IUPAC: unknown (trade secret)

Alkyl Silicone Resin (proprietary) (CAS proprietary) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

Trade-secret ingredient disclosed in the manufacturer's CA Cleaning Product Right to Know Act filing by function only ('Protection Agent'), with CAS withheld. The finished-product GlossCoat SDS mixture classification (WARNING, H229 pressurized container only) does not attribute any hazard code to this specific component. No CAS number is available for independent toxicological cross-check.

This entry represents a proprietary alkyl silicone resin disclosed in SONAX's California Cleaning Product Right to Know Act filing for PROFILINE Ceramic Coating CC36 (Gloss Coat) by function only ("Protection Agent"). No CAS number is assigned because the specific chemical identity is withheld by the manufacturer as a trade secret.

Why this entry exists: CarCareTruth's ingredient data model requires that every SDS/right-to-know-disclosed ingredient appear in the structured YAML — including trade-secret ingredients disclosed by function. This stub ensures the ingredient is visible on the product page and in future automated scoring, even when the identity is unknown.

Alkyl silicone resins generally: Alkyl-modified silicone resins are used in automotive coatings to add gloss, slickness, and a degree of surface protection, distinct from the reactive ceramic (silsesquioxane) film-former in the BaseCoat. They are chemically distinct from fluorinated (PFAS) chemistry.

Regulatory status

  • No CAS number — cannot be evaluated against TSCA, Prop 65, or EU CLP registries
  • Disclosed under the California Cleaning Product Right to Know Act (CA-RTK) as required by law
