Most common in car-care products

The ingredients that show up across the most products in our catalog.

  1. 1WaterUniversal solvent and carrier236 products
  2. 2Petroleum Distillates, Hydrotreated LightCarrier solvent, wax dispersant, penetrating agentVOC86 products
  3. 32-ButoxyethanolSolvent, degreaser, and surfactant aid in engine degreasers, all-purpose cleaners, and car wash concentratesVOC59 products
  4. 4Isopropyl AlcoholCarrier solvent and surface degreaser; flash-evaporates to leave actives on the surfaceVOC56 products
  5. 5Polydimethylsiloxane (PDMS)Linear silicone polymer — forms a protective, non-greasy film on plastics, vinyl, and rubber. Provides UV screening and surface conditioning without the greasy residue of silicone oils.52 products
  6. 6Carbon DioxideNon-flammable aerosol propellant; pressurizes aerosol cans for tire shines, engine degreasers, and similar products where flammability reduction is a formulation goal. In solvent-based engine degreasers, CO2 is the propellant of choice because it does not add flammable mass to an already combustible petroleum-distillate carrier.45 products
  7. 7FragranceScent additive at trace concentrations in consumer product formulations41 products
  8. 8PropaneAerosol propellant — pressurizes the can and helps atomize liquid contents into fine mist39 products
  9. 9AcetoneFast-evaporating carrier solvent; used in aerosol fresheners and some panel prep products as an acetone-based propellant carrier37 products
  10. 10EthanolCarrier solvent, surface prep, quick-dry agent; also used in glass cleaners and surface wipes for fast-evaporating clean finishVOC31 products
  11. 11Aluminum Oxide (Alumina)Micro-abrasive cutting agent in compounds and polishes27 products
  12. 12d-LimoneneCitrus-derived solvent for grease, adhesive, and sapVOC27 products
  13. 13TolueneAromatic hydrocarbon solvent for dissolving varnish, gum, and carbon deposits in carburetor and throttle-body cleaners; co-solvent in some bug-and-tar removersVOCP6527 products
  14. 14Dimethyl Siloxane (PDMS)Silicone polymer; provides lubrication, gloss, and water-repellency25 products
  15. 15Alcohols, C9-C11 EthoxylatedNonionic wetting and emulsifying surfactant; broad surface compatibility, low-foaming24 products
  16. 16Decamethylcyclopentasiloxane (D5)Volatile carrier solvent; delivers active glaze/silicone ingredients to the surface, then evaporatesVOC24 products
  17. 17Sodium HydroxidepH adjuster, degreaser, and saponifier in strong degreasers and engine cleaners24 products
  18. 18Xylene (mixed isomers)Aromatic hydrocarbon solvent used as a carrier and film-formation aid in petroleum-solvent-based coatings and dressings; provides dissolving power for silicone and polymer actives.VOC24 products
  19. 19DMDM HydantoinFormaldehyde-releasing preservative; antimicrobial at trace concentrations23 products
  20. 20HeptaneVolatile carrier solvent for coatingsVOC22 products
  21. 21Mineral OilLubrication, gloss enhancement, carrier22 products
  22. 22Sodium MetasilicateAlkaline builder and pH booster in degreasers and all-purpose cleaners; provides corrosion inhibition for some metal substrates21 products
  23. 23ButaneAerosol propellant — used with propane to pressurize and atomize aerosol products; higher boiling point than propane provides better spray performance at lower temperatures20 products
  24. 24Carnauba WaxNatural protection wax — gloss, depth, water repellency20 products
  25. 25Diethylene Glycol Monobutyl EtherGlycol ether co-solvent and grease-cutting aid in alkaline cleaners and degreasers; higher boiling point and slower evaporation than 2-butoxyethanolVOC20 products

Solvents 171

What carries the active ingredients. Solvent choice determines flammability, smell, skin irritation, and how fast a product flashes off.

Alcohol solvents

Aliphatic solvents

Aromatic solvents

Glycol ether solvents

Other solvents

Surfactants 113

Soaps. They reduce surface tension so dirt lifts off — but the type matters: anionics strip wax/sealant, amphoterics are gentle, nonionics are workhorses.

Anionic surfactants

Nonionic surfactants

Amphoteric surfactants

Cationic surfactants
