Curcylic™ 40 – Water-Soluble Salicylic Acid
Preservative: None
INCI Name: Cocamidopropyl Dimethylamine (and) Salicylic Acid
CAS Number: 68140-01-2 (and) 69-72-7
Description
Curcylic™ 40 is a water-soluble salicylic acid complex containing 40% salicylic acid (BHA). Ordinary salicylic acid barely dissolves in water, so formulators usually need alcohol or glycols to get it into a product. Curcylic™ 40 dissolves straight into the water phase, giving clear, stable formulations that are well tolerated on skin.
As a keratolytic exfoliant, salicylic acid helps loosen dead skin cells, leaving skin looking smoother and pores looking clearer. It is a popular choice for exfoliating toners, cleansers and scalp care.
