Tri-PPG-3 Myristyl Ether Citrate
INCI: TRI-PPG-3 MYRISTYL ETHER CITRATE
A mild, citrate-based emulsifier that helps create stable, creamy textures without common irritation.
In plain English
Tri-PPG-3 Myristyl Ether Citrate is a gentle ingredient that helps oil and water mix together in skincare products. Think of it as a friendly bridge that keeps your lotion or cream from separating. It's made from citric acid (found in citrus fruits) and a modified fatty alcohol, so it's considered mild and unlikely to cause stinging or redness.

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 Tri-PPG-3 Myristyl Ether Citrate.
- 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 emulsifier derived from citric acid and PPG-3 myristyl ether. It belongs to the citrate ester family and is designed to stabilize oil-in-water emulsions.
How it works
It reduces the surface tension between oil and water droplets, allowing them to blend into a smooth, uniform cream or lotion. This prevents the product from separating over time and gives it a pleasant, silky feel on the skin.
Pros
Gentle on skin
Derived from citric acid, this emulsifier is known for its low irritation risk, making it suitable for sensitive skin types.
Stable formulas
It helps maintain the texture and consistency of creams and lotions, so your product stays effective and pleasant to use over time.
Cons and cautions
Limited research
There are fewer peer-reviewed studies on this specific ingredient compared to classic emulsifiers, so long-term data is less robust.
Not for water-free products
It is designed for emulsions and won't work in anhydrous (water-free) formulas like balms or oils.
Best for
- People with normal to dry skin looking for a stable moisturizer
- Those who prefer mild, citrate-based emulsifiers over harsher alternatives
Use caution if
- Individuals with known allergies to citric acid derivatives (very rare)
