Question 1

What does Sodium Carboxymethyl Beta-Glucan do in a cosmetic formula?

Accepted Answer

This ingredient is used as a skin-conditioning humectant and film-forming polymer. It helps bind water, improve skin feel, and support soothing or barrier-focused claims in leave-on formulas.

Question 2

Is Sodium Carboxymethyl Beta-Glucan clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well-tolerated and has little restricted-list friction. The main caveat is processing, since it is a chemically modified natural polymer rather than a minimally processed raw material.

Question 3

Is Sodium Carboxymethyl Beta-Glucan sustainable?

Accepted Answer

This material is typically based on a renewable polysaccharide feedstock and is expected to be biodegradable. Its sustainability profile depends on the feedstock source and the controls used for chemical modification and purification.

Question 4

Is Sodium Carboxymethyl Beta-Glucan COSMOS-approved?

Accepted Answer

This ingredient has partial COSMOS alignment and may be usable in COSMOS-natural formulas when the source and processing route meet the standard, but it is not automatically COSMOS-organic. Its Green Chemistry profile is moderate, with a renewable backbone and good water compatibility, balanced by additional chemical processing.

Question 5

How does Sodium Carboxymethyl Beta-Glucan work chemically?

Accepted Answer

The molecule is a water-soluble, anionically modified polysaccharide designed to improve solubility and skin substantivity versus the unmodified parent polymer. It is typically used at low levels, often around 0.01% to 0.5%, and is best added to the water phase with attention to compatibility with strongly cationic materials.
