Sodium Lauramido Diacetate
INCI: SODIUM LAURAMIDO DIACETATE
A gentle surfactant that cleanses effectively without over-drying, making it a good choice for sensitive or dry skin.
In plain English
Sodium Lauramido Diacetate is a mild soap-like ingredient that helps water mix with oil and dirt so they can be rinsed away. It creates a soft lather and is much less harsh than traditional sulfates, so it won't leave your skin feeling tight or stripped.

Quick decision guide
Useful, but context matters
Sodium Lauramido Diacetate 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 Lauramido Diacetate.
- 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 made from lauric acid (found in coconut or palm oil) and an amino acid derivative. It belongs to the class of amphoteric surfactants, meaning it can work in both acidic and alkaline conditions, making it versatile in cleansers.
How it works
It reduces the surface tension between water and oil, allowing dirt, sebum, and makeup to be emulsified and washed away. Its mild amphoteric nature means it is gentle on the skin barrier and less likely to cause irritation compared to anionic surfactants like SLS.
Pros
Gentle on skin
Its amphoteric nature makes it much milder than common sulfates, reducing the risk of irritation and dryness, especially for those with sensitive or eczema-prone skin.
Good foam quality
It produces a soft, stable lather that feels luxurious without being overly bubbly, which can help make cleansing feel more satisfying.
Cons and cautions
Limited cleansing power
On its own, it may not effectively remove heavy makeup or waterproof sunscreen, so it is often used in combination with other surfactants.
Sourcing concerns
Lauric acid is often derived from palm oil, which has environmental and ethical concerns related to deforestation and habitat loss.
Best for
- People with dry or sensitive skin who need a gentle daily cleanser
- Those looking to avoid harsh sulfates in their skincare routine
Use caution if
- Individuals with very oily or acne-prone skin may prefer a stronger surfactant for deeper cleansing
Usage tips
Safety summary
Sodium Lauramido Diacetate is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, making it suitable for sensitive skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Studies on amphoteric surfactants like this one show they are significantly milder than anionic surfactants. However, specific peer-reviewed research on Sodium Lauramido Diacetate is limited; most safety data comes from broader surfactant safety assessments.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off products.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- While biodegradable, its sourcing from palm oil may contribute to deforestation unless certified sustainable palm oil is used.
Good to know
- This ingredient is often listed alongside other mild surfactants in 'sulfate-free' formulas.
- It is considered biodegradable and generally safe for aquatic life at typical use concentrations.
