Ingredient review
Potassium Lauroyl Hydrolyzed Collagen
INCI: Potassium Lauroyl Hydrolyzed Collagen
A mild, collagen-derived surfactant that cleanses gently and helps maintain skin's moisture barrier.
In plain English
This ingredient is a gentle cleanser made by combining lauric acid (from coconut or palm oil) with hydrolyzed collagen (broken-down animal protein). It works like a soap but is much milder, so it cleans dirt and oil without leaving your skin feeling tight or dry. It also helps condition the skin, leaving it soft and smooth.

Quick decision guide
Useful, but context matters
Potassium 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 Potassium 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 reacting lauric acid with hydrolyzed collagen. It belongs to the class of acyl amino acid surfactants, known for their mildness and compatibility with sensitive skin.
How it works
It reduces the surface tension of water, allowing oils and dirt to be rinsed away. Unlike harsher sulfates, it has a larger molecular structure that is less penetrating, so it cleans effectively without stripping the skin's natural moisture barrier. The collagen portion also deposits a thin conditioning film on the skin.
Pros
Ultra-gentle cleansing
Unlike sodium lauryl sulfate, this surfactant cleans without disrupting the skin barrier, making it ideal for daily use on sensitive or dry skin.
Conditioning effect
The hydrolyzed collagen component leaves a light film on skin that helps maintain softness and reduce post-wash tightness.
Cons and cautions
Not vegan-friendly
Since it is derived from animal collagen, it is unsuitable for those following a vegan or vegetarian lifestyle.
Lower foam volume
It produces a creamy, low-foam lather rather than big bubbles, which some users may associate with less cleansing power.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone wanting to avoid harsh sulfates like SLS or SLES
Use caution if
- Vegans or those avoiding animal-derived ingredients
Usage tips
Safety summary
Potassium Lauroyl Hydrolyzed Collagen is considered safe for use in cosmetics. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in standard safety assessments. As with any ingredient, patch test if you have known allergies to collagen or lauric acid.
Research notes
Acyl amino acid surfactants, including this ingredient, have been studied for their mildness and skin compatibility. Research indicates they cause less protein denaturation and lipid extraction compared to traditional anionic surfactants, supporting their use in sensitive-skin formulations.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for cosmetic use globally, including by the EU CosIng database and US FDA (as a cosmetic ingredient). No concentration restrictions in rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Biodegradable and generally considered eco-friendly compared to some synthetic surfactants, though the animal-derived source may raise sustainability concerns for some consumers.
Good to know
- This ingredient is often found in 'sulfate-free' cleansers and is considered a premium alternative to harsher surfactants.
- The collagen used is typically sourced from bovine or fish by-products, so check labels if you have specific dietary or ethical preferences.
