Ingredient review
Sodium Lauroyl Millet Amino Acids
INCI: Sodium Lauroyl Millet Amino Acids
A mild, plant-based surfactant that cleanses without stripping the skin barrier.
In plain English
This ingredient is a gentle cleanser made from the amino acids (protein building blocks) found in millet, combined with lauric acid from coconut or palm. It works like a soap but is much kinder to your skin because it has a pH close to your skin's natural level and doesn't remove too many natural oils. Think of it as a soft, foaming wash that leaves your face feeling clean but not tight or dry.

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 Millet 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
Sodium Lauroyl Millet Amino Acids is a surfactant created by reacting lauric acid (a fatty acid from coconut or palm oil) with amino acids derived from millet. It belongs to the family of amino acid surfactants, known for their mildness and compatibility with sensitive skin.
How it works
In a cleanser, this molecule has a water-loving head (the amino acid part) and an oil-loving tail (the lauric acid part). When you lather it with water, the tails grab onto dirt, oil, and makeup, while the heads stay in the water. Rinsing washes away the whole complex, leaving skin clean. Because it's an amino acid-based surfactant, it has a pH around 5.5–6.5, which is close to skin's natural pH, so it doesn't disrupt the acid mantle.
Pros
Ultra-gentle cleansing
Unlike harsh sulfates, this surfactant cleans without stripping the skin's natural oils, making it ideal for daily use on sensitive or dry skin.
pH-balanced for skin
Its pH is naturally close to skin's 5.5, so it helps maintain the acid mantle and reduces the risk of irritation or tightness after washing.
Cons and cautions
Lower cleansing power
It may not fully remove heavy, long-wear makeup or sunscreen in a single wash, often requiring a double-cleansing routine.
Higher cost
Amino acid surfactants are more expensive to produce than traditional sulfates, which can increase the price of the final product.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a high-foam, squeaky-clean feel (may find this too mild)
Usage tips
Safety summary
Sodium Lauroyl Millet Amino Acids is considered safe for use in cosmetics at typical concentrations. It has a low irritation and comedogenic risk, making it suitable for sensitive skin. No significant safety concerns have been reported in cosmetic use.
Research notes
Amino acid surfactants in general have been studied for their mildness and skin compatibility. While specific studies on millet-derived versions are limited, the broader class is well-documented as gentle alternatives to sulfates. Evidence supports low irritation potential and good skin tolerability.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics worldwide, including by the FDA (as a cosmetic ingredient) and under EU CosIng regulations. No known restrictions.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from renewable plant sources (millet and coconut/palm). Biodegradability is high, but palm sourcing may raise sustainability concerns unless certified sustainable.
Good to know
- This ingredient is biodegradable and considered environmentally friendlier than many synthetic surfactants.
- It is often labeled as 'sulfate-free' and 'amino acid-based' on product packaging.
