Tremella ●
TL;DR. This ingredient is used primarily as a humectant and skin-conditioning agent, helping bind water and improve slip in water-based formulas.
What does Tremella do in a cosmetic formula?
This ingredient is used primarily as a humectant and skin-conditioning agent, helping bind water and improve slip in water-based formulas.
Is Tremella clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. Sensitivity concerns are typically more about the full extract system, such as preservatives or residual solvent choices, than the material itself.
Is Tremella sustainable?
This material is derived from renewable fungal biomass and its polysaccharide fraction is expected to be biodegradable. Its sustainability profile depends on cultivation practices, extraction method, and whether the formula relies on lower-impact solvents such as water or glycerin.
Is Tremella COSMOS-approved?
It can be used in COSMOS-natural and COSMOS-organic formulas when produced with approved extraction, solvent, and preservation methods. It fits Green Chemistry principles well when sourced from cultivated biomass and processed with water-based, low-residue extraction.
How does Tremella work chemically?
The molecule profile is dominated by high-molecular-weight acidic heteropolysaccharides, which form flexible water-binding films on skin and can add a light gel texture. Typical use is often in the 0.1% to 5% range for extracts, with purified polysaccharide inputs used lower, and it is best formulated in the water phase with attention to preservative compatibility.
