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 Lauryl Aminopropylglycine.
- 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
Lauryl aminopropylglycine is a synthetic amphoteric surfactant, meaning it can behave like both a mild acid and a base. It is derived from lauric acid (a fatty acid found in coconut or palm oil) and the amino acid glycine. This combination gives it excellent foaming and cleansing properties with very low irritation potential.
How it works
In a cosmetic product, lauryl aminopropylglycine reduces the surface tension between water and oil, allowing the product to lift away sebum, makeup, and environmental debris. Because it is amphoteric, it remains effective across a wide pH range and is compatible with other gentle surfactants, helping to create a stable, mild cleansing formula.
Pros
Very gentle on skin
Lauryl aminopropylglycine is known for its low irritation potential, making it an excellent choice for sensitive skin and daily use without causing redness or tightness.
Effective cleanser
It efficiently removes dirt, oil, and light makeup while producing a pleasant foam, so you get a satisfying clean without harshness.
Cons and cautions
Synthetic ingredient
Although derived from natural fatty acids, it is chemically processed, which may be a drawback for consumers seeking 100% natural formulations.
Potential for over-drying
If used alone or at high levels, it can still be somewhat drying, so it is usually blended with other mild surfactants or moisturizing agents.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle daily facial cleanser
Use caution if
- Individuals who prefer exclusively natural or plant-derived ingredients
