Lactase ●
TL;DR. This ingredient functions as an enzyme in personal care formulas, used mainly for biochemical modification of sugar-based substrates rather than as a classic moisturizer, preservative, or emulsifier. In finished products, it may be included for skin-conditioning or formula-processing purposes when enzymatic activity is desired.
What does Lactase do in a cosmetic formula?
This ingredient functions as an enzyme in personal care formulas, used mainly for biochemical modification of sugar-based substrates rather than as a classic moisturizer, preservative, or emulsifier. In finished products, it may be included for skin-conditioning or formula-processing purposes when enzymatic activity is desired.
Is Lactase clean?
From a clean-beauty perspective, this ingredient is generally not a restricted-list concern and is biodegradable. The main caveat is protein-enzyme sensitivity, especially for workers handling powders or aerosols, while finished topical use is typically much lower exposure.
Is Lactase sustainable?
This material is commonly made by microbial fermentation, which can be a relatively efficient route compared with petroleum-derived synthesis. It is readily broken down as a protein, with low environmental persistence expected.
Is Lactase COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic frameworks when produced by approved fermentation routes, with non-GMO and processing-aid requirements applying. Its Green Chemistry profile is generally favorable because it is fermentation-derived, active at mild conditions, and biodegradable.
How does Lactase work chemically?
This compound is a protein enzyme that cleaves a specific glycosidic bond in milk sugar, producing two smaller simple sugars. Activity is source-dependent, with many commercial forms working best around mildly acidic to neutral pH and losing activity with high heat, strong acids or bases, oxidizers, and enzyme-denaturing preservatives.
