Natural fatty acid with favorable safety profile. Not classified as hazardous under GHS at normal use concentrations. No Prop 65 listing. Common in cosmetics, foods, and personal care products. Essentially non-toxic by skin contact.
Linoleic acid (CAS 60-33-3) is an omega-6 polyunsaturated fatty acid naturally present in plant oils (sunflower, safflower, soybean) and animal fats. In leather conditioners, it functions as an emollient and conditioning agent, penetrating the leather fiber structure to restore suppleness and moisture.
It is readily biodegradable and naturally derived. Aquatic toxicity data shows some ecotoxicity at ingredient level in laboratory conditions, though environmental risk at product-use concentrations is low given rapid biodegradation. No GHS health hazard classification at the concentrations found in conditioning formulas.
