Hydrolysed Wheat Protein
INCI · Hydrolyzed Wheat Protein
Hydrolysed wheat protein (INCI: Hydrolyzed Wheat Protein) is a water-soluble hydrolysate of wheat protein broken into small peptides and amino acids. Its appeal in hair care comes from combining moisture attraction, a humectant-like property, with a thin film on the strand. Together these are assessed for the appearance of body, control and shine, making it common in shampoos, conditioners and masks. In shampoos, a light protein film also helps balance the dry feeling left by washing. An important limit: its effects are superficial and temporary. It gives temporary fullness and body without permanently changing strand diameter or internal structure; 'permanent thickening' is not a cosmetic claim. On safety, cosmetic ingredient assessment groups have noted that topical cosmetic use is a different context from dietary wheat sensitivity, although patch testing remains measured for known skin sensitivity. As a mixture of variable molecular weight, hydrolysed wheat protein has no single CID record; its reference framework uses general source families. Klaris considers it alongside moisture-protein balance and the complete formula.
i. Cosmetic Functions
Frequently Discussed Effects
The following headings summarise areas of effect frequently discussed in the literature; visible results in each area require regular use and a suitable formula.
Moisture + Film Balance
Combines water binding and surface-film properties, contributing to moisture and the appearance of body.
Temporary Body and Fullness
A film on the strand supports temporary fullness and a shinier appearance.
Gentle Cleansing Context
In shampoos, a light protein film helps balance the dry feeling left by washing.
Mechanism
What Happens Within the Skin?
The following points summarise mechanisms from dermocosmetic literature in plain English. Klaris presents them as background information to help readers understand the context, not as medical claims.
Step 1
Amino Acid and Peptide Mixture
Wheat protein broken into small, water-soluble pieces; a mixture of variable molecular weight.
Step 2
Moisture + Surface Film
Combines water binding and surface-film formation, contributing to the appearance of body, control and shine.
Step 3
Temporary Surface Effects
Effects remain temporary and at the surface, without permanently changing strand diameter or internal structure.
ii. Role in the Formula
How Is It Read on a Label?
Hydrolysed wheat protein is a mixture of amino acids and low-molecular-weight peptides, combining moisture attraction and surface-film formation. Shampoos, conditioners and masks use it for body, control and a shinier appearance. Effects are superficial and temporary, not permanently changing strand diameter or structure. It can also appear in skincare for moisturising.
Typical Concentration Range
0.5% - 5% (depending on formula context)

iii. Sensitivity Advisory
A Note on Extra Care in Context
Generally well tolerated in cosmetics; topical cosmetic use is a different context from dietary wheat sensitivity. With known skin sensitivity, patch testing a new product is a measured approach.
A sensitivity advisory is not an instruction for use; where individual health circumstances, pregnancy or known sensitivities are involved, discussing the decision with your doctor may be a more contextual approach.
