The global 12-hydroxystearic acid (12-HSA) market stood at USD 300 million in 2025 and is projected to reach USD 445.8 million by 2034, at a CAGR of 4.5% over the forecast period, according to Dataintelo. 12-Hydroxystearic acid is a specialty hydroxy fatty acid used primarily as a thickening and gelling agent for greases, lubricants and personal care products.

12-Hydroxystearic acid serves as the key thickener for lithium and other soap-based greases, as a gelling agent in personal care and cosmetic formulations, and as an intermediate for specialty fatty-acid chemistry and industrial applications. Demand is tied to the expansion of lubricant and grease production, the growth of automotive and industrial maintenance, and the rising use of specialty fatty acids for high-performance formulations. Asia-Pacific is the fastest-growing region, supported by extensive lubricant, automotive and industrial industries in China, India and Southeast Asia.

Europe and North America sustain steady demand in premium grease and personal care applications. Continued lubricant and industrial growth positions 12-hydroxystearic acid as a steadily advancing specialty grease and lubricant thickener.
