Question 1

What does Protease 6.0 do in a cosmetic formula?

Accepted Answer

It functions as a biochemical exfoliant and stain or protein-soil breakdown aid, helping loosen surface buildup in skin, scalp, or cleansing formulas. It is used for activity rather than texture, so formulators usually pair it with buffers and stabilizers.

Question 2

Is Protease 6.0 clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally accepted when well purified and used at controlled levels, but it carries some friction because protein catalysts can trigger irritation or sensitization in some users, especially in powders or aerosols. Finished-product testing and clear supplier data matter more than the name alone.

Question 3

Is Protease 6.0 sustainable?

Accepted Answer

This material is typically made by fermentation, often from microbial sources, and it is expected to break down readily in the environment. Sustainability depends on the production organism, nutrient inputs, carrier, and preservative package supplied with the commercial grade.

Question 4

Is Protease 6.0 COSMOS-approved?

Accepted Answer

It can align with COSMOS-natural when fermentation-derived and made without excluded biotechnology inputs, with compliance dependent on the exact supplier documentation and additives in the preparation. From a Green Chemistry view, it scores well for catalytic efficiency, mild processing conditions, and biodegradability, with caveats around fermentation controls and formulation stabilizers.

Question 5

How does Protease 6.0 work chemically?

Accepted Answer

The molecule is a high-molecular-weight protein catalyst that cleaves peptide bonds and is typically most active near mildly acidic to neutral pH, with “6.0” often indicating an activity optimum around pH 6. Activity can be reduced by high heat, strong oxidizers, extreme pH, and incompatible preservatives or chelators, so it is usually added late in processing and formulated in water systems with pH and temperature control.
