Question 1

What does CHLORELLA PYRENOIDOSA EXTRACT do in a cosmetic formula?

Accepted Answer

This ingredient is used mainly as a skin-conditioning botanical extract, adding antioxidant support, mineral content, and a light humectant feel in serums, creams, masks, and cleansers.

Question 2

Is CHLORELLA PYRENOIDOSA EXTRACT clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well tolerated and not a common restricted-list concern. The main quality questions are extract standardization, preservation, and testing for residual solvents, microbes, and trace contaminants.

Question 3

Is CHLORELLA PYRENOIDOSA EXTRACT sustainable?

Accepted Answer

This material comes from renewable cultivated aquatic biomass rather than petroleum, and its organic components are expected to biodegrade. Sustainability depends on cultivation method, water use, drying energy, and supplier controls for clean growth conditions.

Question 4

Is CHLORELLA PYRENOIDOSA EXTRACT COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic when made from approved biomass using permitted extraction solvents such as water, ethanol, glycerin, or carbon dioxide. Its Green Chemistry profile is favorable when cultivation is efficient and extraction uses benign solvents with limited energy input.

Question 5

How does CHLORELLA PYRENOIDOSA EXTRACT work chemically?

Accepted Answer

This compound is a complex extract containing polysaccharides, amino acids and peptides, minerals, pigments, carotenoids, and minor lipids, so composition varies by cultivation conditions and extraction system. Typical use is often about 0.1% to 5% as supplied, and it is usually best added during cool-down below about 40°C because color and odor can shift with heat, light, high pH, and oxidation.
