What Is Hydrolyzed Caesalpinia Spinosa Gum?
Hydrolyzed Caesalpinia spinosa gum is a thickening agent and viscosity-modifying ingredient that helps improve formulary textures for better aesthetics. It may also possess properties that can enhance skin hydration. Caesalpinia spinosa gum is obtained by grinding the endosperm of seeds of the Caesalpinia spinosa tree. The hydrolyzed version of Caesalpinia spinosa gum is a derivative by method of hydrolysis. Cosmetic suppliers of Caesalpinia spinosa gum tout its ability to provide a “non-sticky, non-stringy, and smooth feel to formulations.” It is also described as providing a soft, velvety after-feel. Hydrolyzed Caesalpinia spinosa gum has been deemed safe by the Cosmetic Ingredient Review Expert Panel. Their report surveyed products containing up to 0.4% (high concentrations aren’t necessary for this ingredient to do its job).
