What it is
Succinoglycan is a high-molecular-weight exopolysaccharide produced by bacterial fermentation, valued for the smooth, non-tacky texture it gives water-based formulas. It thickens and stabilizes emulsions, helps keep solids such as mineral UV filters suspended, and contributes a light, slippery skin feel. In sunscreens it is used as a rheology modifier to improve spreadability and stability.
Safety & warnings
Microbial polysaccharide gums like succinoglycan are generally regarded as mild and well tolerated, functioning purely as texturizers with little irritation or sensitization potential at the low levels used.
Origin & sourcing
Biotechnological; produced by bacterial fermentation and purified into a polysaccharide gum.
Questions everyone asks
What is succinoglycan used for?
It is a fermentation-derived gum used to thicken and stabilize formulas and to give a smooth, light skin feel.
Does succinoglycan affect how a sunscreen feels?
Yes. It is chosen for the non-sticky, slippery texture and good spreadability it lends to water-based formulas.
