The ingredient narratives reshaping clean beauty.
Pullulan
aka alpha-1,6;alpha-1,4-glucan · pullulane · fungal polysaccharide
A polysaccharide produced by Aureobasidium pullulans fermentation used in mascara and hair formulas for film-forming and temporary tightening function.
- Film-forming — creates flexible, breathable films on lashes and skin
- Temporary skin-tightening via film contraction on drying
- Stabilises mascara and serum formulations
- Humectant at higher concentrations
- Biocompatible and biodegradable
- Mascaras
- Lash-lengthening formulas
- Instant firming serums
- Hair styling products
- Temporary tightening eye treatments
Water-soluble; forms clear, flexible films on drying. pH stable. Compatible with most cosmetic ingredients. Effective film-former at 1–5%.
No skin-active benefits beyond film-forming and temporary physical effect. Temporary tightening is a physical, not biological, mechanism.
Accepted in clean beauty as a natural fermentation-derived polysaccharide. EWG rating 1.
