Dihydroxyethyl Soy Glycinate
INCI: Dihydroxyethyl Soy Glycinate
A mild, plant-derived cleansing ingredient that effectively removes dirt and oil without stripping the skin.
In plain English
Dihydroxyethyl Soy Glycinate is a gentle cleanser made from soybean oil. It helps wash away makeup, excess oil, and daily grime while being much less harsh than traditional soaps or sulfates. Because it's derived from a natural source and has a low irritation potential, it's often used in products for sensitive or dry skin.

Dihydroxyethyl Soy Glycinate 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 Dihydroxyethyl Soy Glycinate.
- 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
Dihydroxyethyl Soy Glycinate is a surfactant (a molecule that helps water mix with oil and dirt so they can be rinsed away) derived from soybean fatty acids. It belongs to the class of amino acid–based surfactants, which are known for being mild on the skin.
How it works
In a cosmetic product, this ingredient reduces the surface tension between water and oil, allowing impurities to be lifted from the skin and washed away. Its molecular structure is large and gentle, so it cleanses effectively without penetrating deeply or disrupting the skin's natural moisture barrier.
Pros
Gentle on skin
Its large molecular structure means it cleanses without stripping the skin's natural oils, making it ideal for daily use on sensitive or dry skin.
Plant-derived and eco-friendly
Sourced from renewable soybean oil, this ingredient is biodegradable and aligns with clean beauty and sustainability goals.
Cons and cautions
Limited heavy-duty cleansing
It may not fully remove long-wear or waterproof makeup on its own, so it's often paired with other surfactants in more robust formulas.
Potential for slight dryness at high levels
In very high concentrations, it can still cause mild dryness, though this is rare in well-formulated products.
Best for
- People with sensitive, dry, or reactive skin
- Those looking for a sulfate-free, plant-based cleanser
Use caution if
- Individuals with a known allergy to soy or soybean-derived ingredients
