INCI: PG-Hydrolyzed Soy Protein | Function: Skin Conditioning, Humectant, Film Former | Type: Protein derivative (PG-modified hydrolyzed soy protein)
What Is PG-Hydrolyzed Soy Protein?
PG-modified hydrolyzed soy (Glycine max) protein. Soy proteins are rich in amino acids and contain isoflavones (genistein, daidzein) with antioxidant and potential estrogenic activity. Used for skin conditioning, film-forming, and moisturizing. The PG modification improves the sensory profile — unmodified soy protein can feel tacky.

+ Soy isoflavones — provide additional antioxidant benefits
Pros
+ Rich in amino acids for skin and hair conditioning
+ Soy isoflavones add antioxidant value
+ Vegan and sustainable — plant-derived
+ Better sensory profile than unmodified soy protein
Cons
− Soy allergy concerns — must be labeled for allergic consumers
− Isoflavones may have hormonal activity — controversial in some markets
