Ingredient review
Sodium Cocoyl Threoninate
INCI: Sodium Cocoyl Threoninate
A gentle, amino acid-based cleanser that effectively removes dirt and oil while respecting the skin barrier.
In plain English
Sodium Cocoyl Threonate is a mild cleansing ingredient made from coconut oil and the amino acid threonine. Unlike harsh soaps that can strip your skin's natural oils, this surfactant cleans gently without leaving your face feeling tight or dry. It's often found in sulfate-free cleansers and is well-tolerated by sensitive skin types.

Sodium Cocoyl Threoninate 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 Cocoyl Threoninate.
- 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 Cocoyl Threonate is a surfactant created by combining fatty acids from coconut oil with threonine, an amino acid naturally found in the skin. It belongs to the family of amino acid-based cleansers, known for their mildness and ability to clean without disrupting the skin barrier.
How it works
In a cosmetic product, this ingredient reduces the surface tension of water, allowing it to mix with oils and dirt on the skin. It forms micelles that trap impurities so they can be rinsed away. Because it has a pH close to the skin's natural pH (around 5.5), it cleanses effectively without causing irritation or excessive dryness.
Pros
Extremely gentle on skin
Unlike sodium lauryl sulfate, this surfactant has a low irritation potential and helps preserve the skin's moisture barrier, making it ideal for daily use even on sensitive skin.
pH-balanced cleansing
Its pH is naturally close to the skin's, so it doesn't disrupt the acid mantle, reducing the risk of post-cleansing tightness or irritation.
Cons and cautions
Moderate cleansing power
It may not fully remove heavy, water-resistant makeup or long-wear sunscreen in a single wash, so a double-cleansing routine might be needed.
Higher cost
Amino acid surfactants are more expensive to produce than conventional sulfates, which can increase the price of the final product.
Best for
- People with sensitive, dry, or eczema-prone skin
- Anyone seeking a sulfate-free, gentle daily cleanser
Use caution if
- Those who prefer a very foamy, high-lather cleanser (this produces a creamy, low foam)
Usage tips
Safety summary
Sodium Cocoyl Threonate is considered safe for use in cosmetics. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in scientific literature or regulatory reviews.
Research notes
Amino acid surfactants like Sodium Cocoyl Threonate have been studied for their mildness and skin compatibility. While specific clinical data on this exact compound is limited, the broader class is well-documented as gentle and non-irritating, with good biodegradability.
Common label clues
- Typical concentration
- 1–15% in rinse-off cleansers; lower in leave-on products
- Regulatory status
- Approved for use in cosmetics globally, including by the FDA (as a cosmetic ingredient) and under EU CosIng regulations. No known restrictions at typical use levels.
- Common uses
- Facial cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
