☑ Cosmetics — dual-use vegan protein
Hydrolyzed oat protein is the peptide fraction of oat kernels, hydrolyzed to low-to-medium molecular weight so it penetrates and coats hair and films the skin with moisture. It carries oat’s balanced amino-acid profile (glutamic acid, leucine, arginine, cystine) and the soothing reputation of the oat family: hydrolyzed proteins hydrate, add body, reduce breakage, and improve the feel of cleansers [1], and oat preparations calm irritated skin [2]. It is the softest-feeling of the plant proteins — a vegan alternative to keratin for hair and a gentle film-former for sensitive-skin products — with a caveat that oat sensitization occurs in some highly atopic children [3], so ORY® specifies certified gluten-free, low-MW grades and keeps facial-cleanser levels modest.
What is Hydrolyzed Oat Protein made of?
Hydrolyzed oat protein is produced by enzymatic hydrolysis of oat kernel protein, filtered and standardized. Points to know [1]:
- Amino-acid profile: Balanced, cystine-containing; supports NMF and film formation.
- Molecular weight: Typically 1,000–3,000 Da (penetrating plus film-forming).
- Certified gluten-free grades: For celiac-conscious customers (oats are inherently gluten-free but cross-contaminated).
- Physical form: Amber aqueous solution (20–25% solids) or powder; water-soluble; pH 4–7; add at cool-down.
- Typical use: 0.5–3% haircare; 0.5–2% skincare; 0.5–1% cosmetics.
What skin type is best suited for Hydrolyzed Oat Protein?
Hydrolyzed oat protein suits all seven ORY® skin types as a soothing film-former:
- Dry: Hydrolyzed oat protein forms a moisture-binding film and supplies amino acids supporting the natural moisturizing factor.
- Mature: Film-forming peptides give a smoothing, tightening feel.
- Sensitive: Oat-family soothing; rare oat sensitization in highly atopic children [3] — patch test; certified gluten-free grades.
- Normal: Light hydration and silky feel.
- Combination and Oily: Oil-free film-forming hydration at low levels.
- Acne-prone: Non-comedogenic; keep levels low in leave-ons.
What hair type is best suited for Hydrolyzed Oat Protein?
Hydrolyzed oat protein softens, hydrates, and strengthens hair:
- Dry or damaged: Moisture-binding peptides fill cuticle gaps; softness and strength.
- Curly and coily: Softening protein that resists stiffness; balance with moisture.
- Color-treated or chemically processed: Reinforces weakened fibers.
- Straight and wavy: Light body and shine.
- Mature or thinning: Strength for fine hair.
- Sensitive scalp: Oat-family soothing.
- Oily and dandruff-prone scalp: Rinse-off use; neutral.
What are the benefits of Hydrolyzed Oat Protein?
Hydrolyzed oat protein’s benefits are supported by protein-cosmetics and oat literature [1–3]:
- Moisture binding: Peptides hold water on hair and skin [1].
- Softness and strength: Reduces breakage; soft feel.
- Skin film-forming hydration: Smoothing, calming film [1, 2].
- Soothing oat heritage: Calms irritated skin [2].
- Cleanser mildness: Reduces surfactant harshness.
- Vegan keratin alternative: Plant-based repair.
- Gluten-free grades: Broad suitability.
