Myristoyl Hydrolyzed Collagen
INCI: Myristoyl Hydrolyzed Collagen
A gentle, fatty-acid-modified collagen that helps cleanse without stripping and leaves skin feeling soft.
In plain English
Myristoyl Hydrolyzed Collagen is a modified protein made by attaching a fatty acid (myristic acid) to collagen peptides. This makes it mild and able to cleanse the skin while also helping it feel smooth and hydrated. Unlike harsh soaps, it doesn't strip away too much of your skin's natural oils.

Quick decision guide
Useful, but context matters
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 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 ingredient created by chemically bonding myristic acid (a fatty acid found in coconut oil) with hydrolyzed collagen (broken-down collagen proteins). The result is a mild surfactant and conditioning agent.
How it works
It works as a gentle cleansing agent that helps remove dirt and oil without damaging the skin barrier. The collagen portion provides film-forming and moisturizing properties, while the fatty acid part gives it mild foaming and emulsifying abilities.
Pros
Gentle cleansing
Unlike traditional sulfates, this ingredient cleanses without stripping the skin's natural moisture barrier, making it suitable for daily use on sensitive or dry skin.
Conditioning feel
The collagen peptides leave a light film on the skin that helps reduce tightness after washing, so skin feels softer and more comfortable.
Cons and cautions
Animal-derived source
Since it's made from collagen (typically from bovine or fish sources), it is not suitable for vegans or those who prefer plant-based ingredients.
Limited standalone efficacy
While it improves skin feel, it does not deliver the same anti-aging benefits as intact collagen or other active peptides when used in rinse-off products.
Best for
- People with dry or sensitive skin looking for a mild cleanser
- Anyone wanting a conditioning cleanser that doesn't over-strip
Use caution if
- Strict vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Myristoyl Hydrolyzed Collagen is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch test if you have known sensitivities.
Research notes
Research on this specific modified collagen is limited, but studies on similar acylated collagen peptides indicate they are mild surfactants with good skin compatibility. The safety of hydrolyzed collagen and myristic acid individually is well-established in cosmetics.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Cleansers, Shampoos, Conditioners, Bar soaps, Facial washes
- Environmental note
- The collagen source is typically a byproduct of the meat or fishing industry, which can be considered more sustainable than virgin materials, but the animal origin may raise ethical concerns for some consumers.
Good to know
- Myristic acid is naturally found in coconut oil and palm oil.
- This ingredient is often used in 'gentle' or 'hydrating' cleanser formulas.
