Science
Mechanism of Action
This ingredient functions by supplying peptides and amino acids that closely resemble the skin's Natural Moisturizing Factors (NMF), effectively drawing and retaining water in the uppermost skin layers to enhance moisture, softness, and smoothness. It actively supports the stratum corneum, reducing transepidermal water loss (TEWL) and bolstering barrier function through interactions with vital skin proteins like keratin. Additionally, its soy-derived peptides and isoflavones offer antioxidant benefits, neutralizing free radicals and diminishing oxidative stress. There is also suggestive evidence for its potential to stimulate collagen and elastin synthesis. The 'methacryloyl' modification is primarily for biomaterial applications, such as photocrosslinking, and does not alter its fundamental skincare mechanism.

The Formula
Formulation
Stability
METHACRYLOYL HYDROLYZED SOY PROTEIN, like its unmodified counterpart, is water-soluble. Its solubility is lowest around pH 4.0-5.0 but significantly improves at pH levels further away, achieving nearly 100% solubility at pH 2.0, and between pH 9.0-11.0. Activity is optimally maintained between pH 5-8. It is not advisable to formulate this ingredient above 40 degrees Celsius.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed soy proteins and peptides, including Hydrolyzed Soy Protein (the base for this ingredient), safe for cosmetic use under current practices. A maximum reported concentration for Hydrolyzed Soy Protein is 3.5% in mascara formulations. Dermal studies indicate it is non-irritating and non-sensitizing at concentrations up to 25%. Ocular assays predicted it to be non-irritating to slightly irritating at concentrations up to 35%. There is no specific SCCS or FDA cosmetic status for METHACRYLOYL HYDROLYZED SOY PROTEIN, although related soy proteins have been reviewed in other contexts. This ingredient is generally regarded as non-toxic.
