Mechanism of Action
The precise topical mechanism of action for MICROCOCCUS/HYDROLYZED NONFAT MILK FERMENT is not extensively detailed in available public research. While a similar ingredient, 'LACTOBACILLUS/NONFAT MILK FERMENT POWDER', is listed by COSMILE Europe as a 'SKIN CONDITIONING' agent for maintaining skin health, and the oral consumption of fermented milk has been associated with improved skin hydration and barrier function via bioactive peptides, direct topical benefits for this specific ferment remain largely unsubstantiated in scientific literature. One source lists its function as 'Deodorant' but concurrently states 'No known benefits' in a skincare context.

Stability
The hydrolysis process for milk-based proteinaceous materials typically occurs within a pH range of 6.5 to 8.5, ideally 7.0 to 8.0, at temperatures between 40°C and 60°C. This information pertains to the manufacturing process and not the optimal pH range for the stability of the final ingredient within a cosmetic formulation.
Safety
Safety Profile
A direct safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel, SCCS, or FDA for 'MICROCOCCUS/HYDROLYZED NONFAT MILK FERMENT' is not currently available. However, the CIR Expert Panel has concluded that related ingredients such as 'Bovine Milk Proteins and Protein Derivatives' are safe for use in cosmetics. Specifically, Hydrolyzed Casein has been deemed safe at concentrations up to 30% in diluted bath products and 2% in leave-on formulations, showing no dermal irritation or sensitization in animal or human studies. Additionally, 'Lactobacillus Ferment Ingredients' (byproducts of bacteria, not live bacteria) have been assessed as safe for cosmetic applications. Despite these assessments of related components, a specific review for this exact ingredient combination is lacking, leading to 'insufficient data' for a direct assessment.
