Ingevity

Indulin AA-86 is the trade name (held by Ingevity) for a proprietary formula used for an asphalt emulsifying agent. As such, it does not have a given CAS number. Its composition is only provided subject to a nondisclosure agreement. The company reports that it is a fatty amine derivative, an amber viscous liquid, pH 9 to 11 at a 15% w/w concentration, reactive with acids and oxidizing agents, with a relative density of 0.89, boiling point greater than 180 C and a closed cup flash point of 126 C. It is not volatile, but is identified as a hazard for inhalation, eye or skin contact and must be used with adequate ventilation. The compound is stable and hazardous decomposition products should not be produced during normal use, but in a fire can produce carbon dioxide, carbon monoxide and nitrogen oxides, so firefighters are advised to wear self-contained breathing apparatus. State regulatory disclosures indicate it contains ethyl acrylate. According to the US EPA, "the hydrochloric salt of this product is only acceptable for use in the production of asphalt emulsions, and the emulsions may only be used in asphalt paving applications." Standard usage involves partial neutralization of basic indulin with hydrochloric acid to form a salt, for a 1.0:1.1 ratio of indulin to its salt. via Wikipedia ↗
