What It Does
C18-22 Hydroxyalkyl Hydroxypropyl Guar, commercially known as Esaflor HM 22, is a hydrophobically modified guar gum derivative where the natural guar polysaccharide backbone is functionalized with both hydroxypropyl groups (improving water solubility and reducing syneresis) and long-chain C18-22 hydroxyalkyl substituents (imparting associative thickening behavior). The hydrophobic C18-22 alkyl chains enable this ingredient to form reversible intermolecular networks in aqueous systems, delivering a rich, non-stringy rheology profile particularly valued in rinse-off hair care and skin cleansing formulations. Formulators choose it for its dual role as an associative thickener and hair/skin conditioning agent, providing enhanced sensory feel, improved foam texture, and deposition benefits derived from its natural guar origin.
