Most common in car-care products

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

  1. 1WaterUniversal solvent and carrier202 products
  2. 2Petroleum Distillates, Hydrotreated LightCarrier solvent, wax dispersant, penetrating agentVOC75 products
  3. 3Polydimethylsiloxane (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.50 products
  4. 42-ButoxyethanolSolvent, degreaser, and surfactant aid in engine degreasers, all-purpose cleaners, and car wash concentratesVOCP6549 products
  5. 5Isopropyl AlcoholCarrier solvent and surface degreaser; flash-evaporates to leave actives on the surfaceVOC47 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.39 products
  7. 7PropaneAerosol propellant — pressurizes the can and helps atomize liquid contents into fine mist36 products
  8. 8FragranceScent additive at trace concentrations in consumer product formulations35 products
  9. 9AcetoneFast-evaporating carrier solvent; used in aerosol fresheners and some panel prep products as an acetone-based propellant carrier31 products
  10. 10EthanolCarrier solvent, surface prep, quick-dry agent; also used in glass cleaners and surface wipes for fast-evaporating clean finishVOC25 products
  11. 11TolueneAromatic hydrocarbon solvent for dissolving varnish, gum, and carbon deposits in carburetor and throttle-body cleaners; co-solvent in some bug-and-tar removersVOCP6524 products
  12. 12d-LimoneneCitrus-derived solvent for grease, adhesive, and sapVOC22 products
  13. 13Xylene (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.VOC22 products
  14. 14Alcohols, C9-C11 EthoxylatedNonionic wetting and emulsifying surfactant; broad surface compatibility, low-foaming21 products
  15. 15Decamethylcyclopentasiloxane (D5)Volatile carrier solvent; delivers active glaze/silicone ingredients to the surface, then evaporatesVOC21 products
  16. 16Carnauba WaxNatural protection wax — gloss, depth, water repellency20 products
  17. 17Dimethyl Siloxane (PDMS)Silicone polymer; provides lubrication, gloss, and water-repellency20 products
  18. 18Mineral OilLubrication, gloss enhancement, carrier20 products
  19. 19Aluminum Oxide (Alumina)Micro-abrasive cutting agent in compounds and polishes19 products
  20. 20Distillates, Petroleum, Hydrotreated Heavy NaphthenicCarrier solvent and viscosity modifier in lubricants and penetrating oils19 products
  21. 21DMDM HydantoinFormaldehyde-releasing preservative; antimicrobial at trace concentrations19 products
  22. 22HeptaneVolatile carrier solvent for coatingsVOC19 products
  23. 23Sodium MetasilicateAlkaline builder and pH booster in degreasers and all-purpose cleaners; provides corrosion inhibition for some metal substrates19 products
  24. 24ButaneAerosol propellant — used with propane to pressurize and atomize aerosol products; higher boiling point than propane provides better spray performance at lower temperatures17 products
  25. 25Dimethicone (PDMS)Surface conditioning, UV protection, hydrophobic layer17 products

Solvents 160

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 95

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

Cationic surfactants

Acids, bases & redox 42

How aggressive the chemistry is. The most dangerous ingredients in car care live here.

Acids

Bases

Coatings, polymers, waxes 93

What stays on the paint after the carrier evaporates — the actual protection layer.

Silicones

Polymers

Ceramic (SiO₂)

Oils & lubricants 59

Carrier and film oils — petroleum base oils, mineral oils, and the esters used as plasticizers and emollients in dressings and lubricants.
