2-amino-2-ethyl-1,3-propanediol

2-Amino-2-ethyl-1,3-propanediol (CAS 115-70-8), commonly abbreviated as AEPD, is a multifunctional amino alcohol used across coatings, personal care, and printing formulations.

It combines amine-based pH buffering with diol functionality, making it effective for neutralizing acidic resins and stabilizing emulsions in industrial systems.

In architectural and industrial coatings, AEPD neutralizes acrylic and polyurethane dispersions to improve stability, rheology, and film formation for better performance.

Personal care formulators use it as a pH adjuster and emulsifier in creams, lotions, and hair care products where low odor and skin compatibility are priorities.

In water-based inks for packaging and commercial printing, it helps stabilize pigment dispersions and controls pH to maintain print consistency over time.

Adhesive and sealant manufacturers incorporate it to adjust cure chemistry and improve compatibility between resin components in complex chemical formulations.

AEPD is supplied as a white crystalline solid or as a concentrated aqueous solution, typically at 85% active content for various industrial applications.

Technical and industrial grades are the most common market forms, with specifications aligned to coatings and personal care end-use requirements and standards.
