Question 1

What does Thaumatin do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a flavor modifier and high-intensity sweetening agent, especially in lip care and oral care formulas. It can help mask bitterness without adding meaningful bulk or sugar content.

Question 2

Is Thaumatin clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally low-friction, food-approved in many regions, used at very low levels, and not a common restricted-list trigger. As a protein, it may not suit a small subset of users with specific sensitization, but routine irritation concern is low.

Question 3

Is Thaumatin sustainable?

Accepted Answer

This material is typically plant-derived from fruit arils, with some supply also possible through controlled biotechnology. It is biodegradable as a protein and is not expected to persist or bioaccumulate in the environment.

Question 4

Is Thaumatin COSMOS-approved?

Accepted Answer

This ingredient can align with COSMOS-natural or COSMOS-organic when it is obtained by permitted physical extraction or approved biotechnological processes and preserved with compliant inputs. It fits Green Chemistry well when sourced renewably and processed with mild, low-residue methods.

Question 5

How does Thaumatin work chemically?

Accepted Answer

The molecule is a compact, intensely sweet-tasting protein of roughly 22 kDa, so it functions through taste-receptor activity rather than through sugar-like humectancy. It is typically used at very low ppm-level concentrations, performs across acidic to near-neutral systems, and needs standard protein-aware formulation controls for heat, enzymes, and microbial preservation.
