Why This Works for Your Specific Profile
Damage Index:
Damaged hair structure cannot withstand product intensity causing increased breakage and further compromise
Water Quality:
Hair:
Porous structure over-absorbs product leading to buildup, stiffness, or excessive dryness
Active Lifestyle:
High activity and frequent washing rapidly strip product benefits requiring excessive reapplication

Hydrolyzed Soy Protein
Common Name(s): Hydrolysed protein,conditioning amino acid complex,film-forming active
CAS Number: N/a
DESCRIPTION
What It Does: Deposits a conditioning, moisture-retaining film on skin and hair from substantive protein-surface adsorption, delivers amino acids for sc keratin compatibility, and provides temporary firming from the protein film's tensile properties.
Why It's Used: Provides the conditioning benefits of structural proteins in a topically deliverable form — molecular weight distribution determines whether surface film formation (high mw) or sc penetration with deeper conditioning (low mw <500 da) predominates.
How It Works: Low-mw protein hydrolysate fractions (<500 da) penetrate the sc via aqueous channels; high-mw fractions adsorb substantively to negative hair and skin surfaces through h-bonding and electrostatic interactions. film formation reduces tewl and provides mechanical smoothing.
Typically Found In: Hair conditioners,skin serums,conditioning
TECHNICAL DETAILS
Primary Category: Functional ingredient – humectant
Secondary Functions: Tewl reduction,skin plumping
Application Areas:
Facial Skincare
Body Care
Hair Care
Beard Care
Color Cosmetics (Makeup)
Dietary/Oral Supplements
Typical Concentration Range: 0.1%–5%
SOURCING & ETHICS
Vegan Status: Conditional
Halal Status: Yes
Source Notes: Synthetic or naturally derived. excellent aqueous solubility.
SKIN COMPATIBILITY
Irritancy Rating: 1/5 – very low
Comedogenicity Rating: 0/5 – non-comedogenic
Sensitivity Concerns: Non-irritating; suitable for all skin types.
Safe for Sensitive Skin: Yes
SAFETY & COMPATIBILITY
Safety Profile: Excellent safety profile. ewg score: 1.
Works Well With: Ceramides,emollients,occlusives,glycerin,hyaluronic acid
Avoid Combining With: No significant incompatibilities
SCIENTIFIC NOTE
Optimal hydrolysis degree for hair conditioning: mw 1,000–5,000 da — large enough for adsorption to hair cuticle, small enough to penetrate the cuticle surface and access cortex damage sites.
