What it is
Mannan is a polysaccharide built primarily from mannose sugar units and sourced from plants, yeasts, or other natural materials. In cosmetics it can act as a film former and skin-conditioning agent, and related mannans contribute to texture and viscosity in aqueous systems. It is typically used at modest levels to support feel and product structure rather than as an active.
Safety & warnings
Mannan is a polysaccharide generally regarded as mild and is not associated with significant irritation, allergenicity, or comedogenicity at cosmetic use levels.
Origin & sourcing
Naturally derived; a polysaccharide obtained from plant or microbial (such as yeast) sources.
