Alkyl Ester Carboxylic Acid

  • Esters
  • CAS 68015-93-0

Alkyl Ester Carboxylic Acid (CAS 68015-93-0) appears in 2 of the 2,179 car-care products CarCareTruth tracks (as of August 2026).

Ingredient-level hazard classification per SDS Section 3 (both SDSs agree): Skin Irrit. 2 (H315), Eye Dam. 1 (H318), Skin Sens. 1 (H317); the TLS-LV SDS additionally lists Aquatic Chronic 3 (H412). At the disclosed under-1% concentration, only the skin-sensitization classification (H317) carries through to the finished product's mixture-level Section 2 classification in both products; the eye and skin irritation codes are diluted below the mixture classification threshold. The Idemitsu ATF Type H Plus SDS Section 11 additionally reports LD50 oral > 2,000 mg/kg (rat) and LD50 dermal > 3,160 mg/kg (rabbit) for this component, both low-acute-toxicity results; not identified as a carcinogen, mutagen, or reproductive toxicant by NTP, IARC, OSHA, or ACGIH at its disclosed concentration.

Alkyl ester carboxylic acid (CAS 68015-93-0) is a corrosion-inhibiting, friction-modifying additive used in automatic transmission fluid formulations at low concentration (typically under 1% by weight). It appears under this same generic SDS name and CAS number in more than one Idemitsu ATF product, including Type TLS-LV and Type H Plus, and is the sole ingredient in each product's disclosed composition that carries a Section 3 hazard classification; its skin-sensitization hazard (H317) is what drives each finished fluid's overall Warning signal word. Section 11 toxicology data from the Type H Plus SDS reports LD50 oral > 2,000 mg/kg (rat) and LD50 dermal > 3,160 mg/kg (rabbit), both low-acute-toxicity results. CAS 68015-93-0 does not appear on California's Proposition 65 list (checked against data/prop65/oehha-list.json, 2026-08-25, no match).
