Ingredient review
Sodium Lauroyl Lactylate
INCI: Sodium Lauroyl Lactylate
A mild, skin-friendly surfactant that cleanses without stripping, making it ideal for sensitive or dry skin.
In plain English
Sodium Lauroyl Lactylate is a gentle cleansing agent made from lauric acid (found in coconut oil) and lactic acid (a natural skin moisturizer). It helps water and oil mix in products like cleansers and lotions, and it cleans your skin without being harsh or drying. Think of it as a kinder alternative to stronger detergents like sodium lauryl sulfate.

Quick decision guide
Easy yes for most routines
Sodium Lauroyl Lactylate 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 Lactylate.
- 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
Sodium Lauroyl Lactylate is a semi-synthetic surfactant and emulsifier produced by combining lauric acid (from coconut or palm kernel oil) with lactic acid (from fermentation). It belongs to the acyl lactylate family, known for being mild and compatible with sensitive skin.
How it works
In a cosmetic product, Sodium Lauroyl Lactylate reduces the surface tension between water and oil, allowing them to blend into a stable emulsion. As a surfactant, it helps lift dirt, oil, and impurities from the skin so they can be rinsed away. Its mildness comes from its large molecular structure, which is less penetrating and less irritating than smaller, harsher surfactants.
Pros
Very gentle on skin
Unlike sulfates, Sodium Lauroyl Lactylate has a low irritation potential, making it suitable for daily use on sensitive or compromised skin barriers.
Dual function as emulsifier
It not only cleanses but also helps blend water and oil in creams and lotions, reducing the need for multiple ingredients.
Cons and cautions
Lower foam volume
It produces a creamy, low foam rather than big bubbles, which some users may associate with less cleansing power.
Potential palm oil sourcing
Lauric acid is often derived from palm or coconut oil; if from palm, it may raise environmental concerns unless certified sustainable.
Best for
- People with sensitive, dry, or eczema-prone skin looking for a mild cleanser
- Anyone who prefers gentle, non-stripping cleansing in their daily routine
Use caution if
- Those seeking a high-foam, deep-cleansing experience may find it too mild
Usage tips
Safety summary
Sodium Lauroyl Lactylate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, and no significant toxicity concerns have been reported in regulatory reviews.
Research notes
Research on acyl lactylates, including Sodium Lauroyl Lactylate, indicates they are mild surfactants with good skin compatibility. Studies show they cause less protein denaturation and cell damage compared to traditional anionic surfactants like SLS. However, direct clinical trials on this specific ingredient are limited.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics by the EU CosIng database and the US FDA (as a generally recognized safe indirect food additive). No known restrictions in major markets.
- Common uses
- Facial cleansers, Body washes, Shampoos, Conditioners, Lotions
- Environmental note
- Sodium Lauroyl Lactylate is biodegradable and typically derived from plant-based sources. However, if lauric acid comes from palm oil, look for RSPO-certified sustainable palm oil to minimize environmental impact.
Good to know
- Sodium Lauroyl Lactylate is approved by the CosIng database of the European Commission as a safe cosmetic ingredient.
- It is often used in 'sulfate-free' formulations as a primary or secondary surfactant.
