INCI: PG-Hydrolyzed Rice Protein | Function: Humectant, Film Former, Skin Conditioning | Type: Protein derivative (PG-modified hydrolyzed rice protein)
What Is PG-Hydrolyzed Rice Protein?
PG-modified hydrolyzed rice (Oryza sativa) protein. Rice protein peptides are esterified with propylene glycol for improved solubility and skin feel. Rice proteins contain glutamine, arginine, and other amino acids beneficial for skin and hair. The PG modification makes this a versatile plant-based alternative to animal-derived protein conditioners.
Key Skin Benefits
+ Plant-based protein conditioning — vegan alternative to collagen/keratin
+ Film-forming — creates a light protective layer on skin and hair
+ Humectant — PG component attracts moisture
+ Hair volumizing — rice proteins add body without weighing hair down
Pros
+ Vegan — plant-derived rice protein
+ Good alternative to animal-derived hydrolyzed proteins
+ Adds volume and body to fine hair
+ Light feel — less sticky than unmodified rice protein
Cons
− PG modification reduces 'natural' positioning
− Rice protein has lower cysteine content than keratin — less structural repair
− May not be as effective as animal proteins for severe hair damage
− Limited independent safety studies on this specific derivative
