Ingredient review
Sodium Cocoyl Hydrolyzed Amaranth Protein
INCI: Sodium Cocoyl Hydrolyzed Amaranth Protein
A mild, protein-enriched cleanser that helps clean without stripping the skin or hair.
In plain English
This ingredient is a gentle cleanser made by combining coconut oil fatty acids with protein from amaranth, a nutritious grain. It helps remove dirt and oil while leaving a light conditioning film, so skin and hair feel soft rather than tight or dry. Think of it as a kinder alternative to harsh soaps.

Quick decision guide
Useful, but context matters
Sodium Cocoyl Hydrolyzed Amaranth Protein is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Sodium Cocoyl Hydrolyzed Amaranth Protein.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A surfactant (cleansing agent) created by reacting coconut fatty acids with hydrolyzed (broken-down) amaranth protein. The result is a molecule that can lift away grime while depositing a small amount of protein to help maintain moisture balance.
How it works
In a product, one end of the molecule attracts water and the other attracts oil and dirt. When you rinse, it carries away impurities. The amaranth protein portion stays behind briefly, forming a thin film that can reduce water loss from the skin or hair surface.
Pros
Gentle on skin
Its mild cleansing action helps maintain the skin's natural moisture barrier, making it a good choice for daily use on sensitive or dry skin.
Adds softness
The amaranth protein leaves a light conditioning film that can reduce frizz in hair and prevent that tight, dry feeling after washing.
Cons and cautions
Lower foam
It produces less lather than traditional sulfate cleansers, which some users may find less satisfying or effective for heavy oil removal.
Potential residue
On very fine or oily hair, the protein film might cause slight buildup or limpness over time without proper rinsing.
Best for
- People with dry or sensitive skin
- Those looking for a gentler sulfate-free cleanser
Use caution if
- Individuals with coconut allergies (rare, but possible)
- Those who prefer high-foam cleansers
Usage tips
Safety summary
