Ingredient review
Potassium Olivoyl/Lauroyl Amino Acids
INCI: POTASSIUM LAUROYL/OLIVOYL (ALANINE/ARGININE/ASPARAGINE/ASPARTIC ACID/GLUTAMIC ACID/LYCINE/ISOLEUCINE/LEUCINE/LYSINE/METHIONINE/PHENYLALANINE/PROLINE/SERINE/THREONINE/TRYPTOPHAN/TYROSINE/VALINE)
A mild, plant-derived surfactant that cleanses effectively while respecting the skin barrier — ideal for sensitive or dry skin.
In plain English
This ingredient is a gentle soap-like molecule made from olive oil, coconut fatty acids, and a blend of amino acids (the building blocks of protein). It works by trapping dirt and oil so they can be rinsed away with water, but it's much less harsh than traditional sulfates. Because it's derived from natural oils and amino acids, it cleans without stripping your skin's natural moisture barrier, leaving it feeling soft rather than tight or dry.

Quick decision guide
Easy yes for most routines
Potassium Olivoyl/Lauroyl Amino Acids 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 Olivoyl/Lauroyl Amino Acids.
- 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 combining fatty acids from olive and coconut oils with a mixture of amino acids (like alanine, arginine, and glutamic acid). The result is a potassium salt that acts as a gentle cleansing agent.
How it works
In a cleanser, this molecule has a water-loving head and an oil-loving tail. The tail grabs onto sebum, makeup, and dirt, while the head allows the whole complex to be rinsed away with water. Unlike harsher surfactants, it has a larger molecular size that doesn't penetrate the skin barrier easily, reducing irritation and moisture loss.
Pros
Ultra-gentle on skin
The amino acid base makes this surfactant much milder than sodium lauryl sulfate, reducing the risk of irritation, redness, and dryness — even with daily use.
Supports skin barrier health
Because it doesn't strip away natural oils, your skin's moisture barrier stays intact, helping prevent transepidermal water loss (water escaping from skin).
Cons and cautions
Lower foam volume
This surfactant produces a creamy, low-lather foam rather than big, bubbly suds. If you love a rich foam, you might find it less satisfying.
May struggle with heavy makeup
Its mildness means it's less effective at dissolving long-wear or waterproof makeup on its own — you may need a double-cleansing step.
Best for
- People with dry or sensitive skin who find sulfates too harsh
- Anyone looking for a gentle, everyday facial cleanser
Use caution if
- Those who prefer a very foamy, high-lather cleanser (this produces a creamy, low foam)
Usage tips
Safety summary
Potassium Olivoyl/Lauroyl Amino Acids is considered very safe for cosmetic use. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been reported in standard cosmetic concentrations.
Research notes
Amino-acid-based surfactants are well-documented in cosmetic science for their mildness and skin compatibility. Studies show they cause less protein denaturation and barrier disruption than traditional anionic surfactants like SLS. However, specific clinical trials on this exact blend are limited; safety is inferred from the broader class of acyl amino acid surfactants.
Common label clues
- Typical concentration
- 5–20% in rinse-off cleansers
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of generally recognized safe surfactant categories). No specific restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Micellar waters
- Environmental note
- Derived from renewable plant sources (olive and coconut oils) and amino acids. It is biodegradable and has a lower environmental impact compared to many synthetic surfactants.
Good to know
- This ingredient is often listed near the middle or end of an INCI list because it's used at moderate concentrations.
- It's considered biodegradable and more eco-friendly than many petroleum-based surfactants.
