Frequently Asked Questions ,Enzymes For Cosmetics
What are cosmetic enzymes and how do they benefit skin?
Cosmetic enzymes are protein-based active ingredients used in skincare formulations to selectively break down dead skin cells, support natural exfoliation, improve product penetration, or extend shelf life. The most-used cosmetic enzymes are papain, bromelain, subtilisin, and various proteases.
Which enzymes are used in skincare products?
Papain (from papaya) and bromelain (from pineapple) are plant-derived proteases used in gentle exfoliating cleansers. Subtilisin is a microbially produced serine protease used in stronger leave-on treatments. Lipases support oil-balancing formulations. Each enzyme has a different pH and substrate specificity profile that determines its formulation use.
Are cosmetic enzymes safe for sensitive skin?
Properly formulated cosmetic enzymes are gentler than acid-based exfoliants because they target only dead protein in the upper skin layer rather than breaking the bond between living cells. Sensitivity varies by enzyme — papain and bromelain are typically tolerated at 0.5–2% concentration; subtilisin is used at lower concentrations (0.1–0.5%).
What is the optimal pH range for enzyme cosmetics?
Most cosmetic proteases work best at slightly acidic to neutral pH (4.5–7.0). Papain has a wider optimum (pH 5.0–8.0) than bromelain (pH 4.5–6.0). Formulation chemists design buffer systems to keep the enzyme stable through shelf life while allowing activity on application.
Can cosmetic enzymes be added to natural and clean-label products?
Yes — enzymes are protein actives that fit cleanly into natural, plant-based, and minimal-ingredient formulations. They do not require synthetic preservatives at the ingredient level (though formulations need standard preservation). Enzymes are increasingly featured as the lead active in clean-beauty product launches.
What is the MOQ for cosmetic-grade enzymes?
Standard MOQ is 25 kg, supplied in food-grade or cosmetic-grade HDPE drums with INCI-named documentation, Certificates of Analysis, allergen declarations, and stability test data. Custom blends and pre-buffered solutions are available for formulation partners.
How do I source cosmetic enzymes for my brand?
Reach the cosmetic enzymes team at sales@infinitabiotech.com with the target product type (cleanser, mask, serum), enzyme of interest, expected volume, and any formulation pH range. Sample quantities for R&D trials are available before commercial scale-up.
