Galaxy MW (Lutensol)

Whatsapp Order

Galaxy MW (Lutensol), also known commercially as Lutensol A07, is a nonionic surfactant belonging to the class of ethoxylated alcohols. It is synthesized by ethoxylation of C7 fatty alcohols, resulting in a hydrophilic-lipophilic balance (HLB) suitable for versatile applications in detergency, emulsification, wetting, and dispersing. This liquid surfactant is valued for its excellent surface-active properties, biodegradability, low toxicity, and compatibility with other formulation ingredients. It is widely used in industrial, household, agricultural, and personal care products to improve formulation stability and performance.
