Ingredient review
Sodium Lauroyl Hydrolyzed Collagen
INCI: Sodium Lauroyl Hydrolyzed Collagen
A mild, collagen-derived surfactant that cleanses gently and may leave skin feeling soft, but offers no lasting anti-aging benefits.
In plain English
Sodium Lauroyl Hydrolyzed Collagen is a cleansing ingredient made by attaching a fatty acid (lauric acid) to broken-down collagen proteins. This creates a mild surfactant that helps water mix with oil and dirt so they can be rinsed away. Unlike harsh soaps, it cleans without stripping your skin's natural moisture barrier, and the collagen part may temporarily make skin feel smoother. However, the collagen is too large to penetrate deeply, so it doesn't provide lasting anti-aging effects.

Quick decision guide
Useful, but context matters
Sodium Lauroyl 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 Sodium Lauroyl 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 chemically bonding lauric acid (a fatty acid from coconut or palm oil) with hydrolyzed collagen (collagen broken into smaller peptides). It appears as a mild, water-soluble cleansing agent in many personal care products.
How it works
It reduces the surface tension between water and oils, allowing dirt, sebum, and makeup to be emulsified and rinsed away. The collagen peptides can deposit a thin film on the skin, giving a temporary soft, smooth feel after washing.
Pros
Mild on skin
This surfactant is much gentler than sodium lauryl sulfate, making it a good choice for daily cleansing without stripping natural oils.
Temporary softness
The collagen peptides can leave a light film on skin, giving a smooth feel after washing, which is especially nice for dry or mature skin.
Cons and cautions
No lasting anti-aging effect
Despite containing collagen, the molecules are too large to penetrate the skin barrier, so any smoothing effect is temporary and rinses away.
Animal-derived collagen
Unless specified as plant-based, the hydrolyzed collagen is typically sourced from animal hides or bones, which may not align with vegan or some religious practices.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting a sulfate-free cleansing option that still foams moderately
Use caution if
- Strict vegans or those avoiding all animal-derived ingredients (unless a plant-based collagen alternative is used)
- Individuals with known allergies to collagen or coconut-derived fatty acids
Usage tips
Safety summary
Sodium Lauroyl 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. However, individuals with allergies to collagen or coconut derivatives should avoid it. The Cosmetic Ingredient Review (CIR) panel has not specifically reviewed this ingredient, but similar acyl collagen derivatives are generally recognized as safe.
Research notes
Research on this specific ingredient is limited, but studies on similar acyl amino acid surfactants show they are mild and less damaging to skin barrier function compared to traditional sulfates. The collagen component is not proven to provide anti-aging benefits due to its large molecular size.
Common label clues
- Typical concentration
- 1-10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The EU CosIng database lists it as a surfactant and cleansing agent with no specific restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- This ingredient is generally biodegradable, but the environmental impact depends on the sourcing of lauric acid (palm oil can be linked to deforestation) and the collagen source (animal farming has a higher carbon footprint).
Good to know
- Sodium Lauroyl Hydrolyzed Collagen is often listed in the middle of an ingredient list, indicating moderate concentration.
- It is considered a 'secondary surfactant' and is usually combined with other milder cleansers to improve foam and feel.
- The lauric acid part can come from coconut or palm oil, so check for sustainable sourcing if that matters to you.
