Alkyl Amidopropyl Betaine (Coco/Sunfloweramidopropyl Betaine) (CAS 147170-44-3) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026). It is readily biodegradable.

Classified Eye Dam. 1 (H318, serious eye damage) at the ingredient level. Amidopropyl betaines are generally mild, low-irritation surfactants used to soften the profile of stronger anionic surfactants like laureth sulfates, but concentrated solutions still carry the eye-damage classification common to this surfactant family.

Alkyl amidopropyl betaine is an amphoteric (zwitterionic) co-surfactant in the same chemical family as cocamidopropyl betaine (CAPB), synthesized from a coco/sunflower fatty-acid blend instead of coconut oil alone. It boosts foam density and viscosity and moderates the irritation potential of primary anionic surfactants like ammonium laureth sulfate.

Readily biodegradable, but classified with a chronic aquatic-toxicity hazard (H412) at the ingredient level, which is common across this surfactant class at the concentrations used in mixture SDS classification.
