Lactoperoxidase ●
TL;DR. This ingredient functions as an antimicrobial preservative adjunct, usually as part of an enzyme-based preservation system. It helps control microbial growth by catalyzing reactions that generate short-lived antimicrobial oxidants in the formula.
What does Lactoperoxidase do in a cosmetic formula?
This ingredient functions as an antimicrobial preservative adjunct, usually as part of an enzyme-based preservation system. It helps control microbial growth by catalyzing reactions that generate short-lived antimicrobial oxidants in the formula.
Is Lactoperoxidase clean?
From a clean-beauty perspective, this ingredient is generally viewed as acceptable but not friction-free because it is a bioactive animal-derived protein. The main caveats are dairy sourcing, potential sensitivity in a small subset of users, and the need for careful preservation-system design.
Is Lactoperoxidase sustainable?
This material is typically sourced from dairy streams or made through biotechnology, and it is readily biodegradable as a protein. Its sustainability profile depends mainly on animal-derived sourcing, traceability, and whether the supplier uses side streams from dairy processing.
Is Lactoperoxidase COSMOS-approved?
It can align with COSMOS-natural when sourced and processed according to the standard’s rules, especially if it comes from permitted animal-derived materials or compliant biotechnology. From a Green Chemistry lens, it scores well on biodegradability and catalytic efficiency, with sourcing as the main qualification.
How does Lactoperoxidase work chemically?
This ingredient is a heme-containing glycoprotein enzyme that uses hydrogen peroxide to oxidize substrates such as thiocyanate or iodide into short-lived antimicrobial species. It is typically used at low levels in water-based systems and must be formulated with compatible cofactors, controlled peroxide generation, and pH conditions that preserve enzyme activity.
