Ingredient review
Potassium Myristoyl Hydrolyzed Collagen
INCI: Potassium Myristoyl Hydrolyzed Collagen
A mild, collagen-derived surfactant that cleanses gently and helps maintain skin softness, ideal for sensitive or dry skin.
In plain English
This ingredient is a gentle cleanser made by combining collagen (a protein naturally found in skin) with myristic acid (a fatty acid from coconut or palm oil). It helps remove dirt and oil from your skin without stripping away its natural moisture, leaving it feeling soft and smooth rather than tight or dry.

Quick decision guide
Useful, but context matters
Potassium Myristoyl Hydrolyzed Collagen 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 Potassium Myristoyl Hydrolyzed Collagen.
- 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 semi-synthetic surfactant created by reacting hydrolyzed collagen (broken-down collagen protein) with myristic acid, then neutralizing with potassium. It belongs to the class of amino acid-based surfactants known for their mildness.
How it works
It works by reducing the surface tension between water and oils, allowing dirt and excess sebum to be rinsed away. The collagen portion also deposits a thin, conditioning film on the skin, which helps retain moisture and improve feel after washing.
Pros
Extremely gentle cleansing
Unlike sulfates that can strip oils, this surfactant cleans effectively while preserving the skin's moisture barrier, reducing tightness and irritation.
Conditioning after-feel
The collagen component leaves a subtle film that helps skin feel smooth and hydrated post-wash, which is especially beneficial for dry or mature skin.
Cons and cautions
Animal-derived collagen
The hydrolyzed collagen is typically sourced from animal hides or bones, making this ingredient unsuitable for those following a vegan or vegetarian lifestyle.
Potential palm oil sourcing
Myristic acid is often derived from palm oil, which can be linked to deforestation unless certified sustainable. Check brand sourcing if this matters to you.
Best for
- People with dry or sensitive skin looking for a non-stripping cleanser
- Those who prefer amino acid-based, mild surfactants over harsh sulfates
Use caution if
- Strict vegans or vegetarians concerned about animal-derived collagen
Usage tips
Safety summary
Considered safe for use in rinse-off cosmetics at typical concentrations. Low irritation and sensitization potential. Not recommended for leave-on products at high levels due to potential for slight residue.
Research notes
Amino acid surfactants like this one are well-studied for mildness and skin compatibility. Specific studies on potassium myristoyl hydrolyzed collagen are limited, but the broader class is supported by dermatological literature as gentle alternatives to sulfates.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- The collagen source is typically a byproduct of the meat industry, which can be seen as upcycling waste. However, the palm-derived myristic acid may have environmental impacts unless sourced responsibly.
Good to know
- This ingredient is often listed near the top of ingredient lists in mild cleansers, indicating it's a primary surfactant.
- It is compatible with other mild surfactants like cocamidopropyl betaine to boost foam without increasing irritation.
