Alkyl Imino Dipropionic Acid, Monosodium Salt (CAS 64972-18-5) appears in 1 of the 2,122 car-care products CarCareTruth tracks (as of August 2026).

Classified as a serious eye irritant (H319, Eye Irrit. Cat 2A) at the 0.5-0.8% disclosed concentration in the Optimum Fabric Cleaner & Protectant SDS (§3, rev. 06/09/2023). Amphoteric surfactants of this class are generally low-toxicity cleaning agents; the eye-irritation signal is the only health classification, with no skin-corrosion, sensitization, or systemic hazard listed.

Alkyl imino dipropionic acid monosodium salt is an amphoteric surfactant used as a cleaning and wetting agent in water-based fabric, carpet, and upholstery cleaners. Amphoteric surfactants of this family are chosen because they are mild on surfaces and skin relative to strong anionic surfactants while still cutting soils and grease.

In the Optimum Fabric Cleaner & Protectant SDS (rev. 06/09/2023) it is disclosed at 0.5-0.8% with a single Eye Irrit. 2A (H319) classification. The only environmental data point in Section 12 is an aquatic LD50 of 10 mg/l for fish over 96 hours, which places it among the components contributing to the finished product's H412 chronic-aquatic hazard classification.
