Ingredient review
PPG-3 Myreth-3
INCI: PPG-3-MYRETH-3
A synthetic emulsifier that helps mix oil and water, generally considered safe at low concentrations.
In plain English
PPG-3 Myreth-3 is a man-made ingredient that helps oil and water blend together in products like cleansers and shampoos. It's a type of surfactant, which means it can also help lift dirt and oil from your skin or hair so they rinse away easily. Think of it as a gentle helper that keeps a formula stable and effective.

Quick decision guide
Useful, but context matters
PPG-3 Myreth-3 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 PPG-3 Myreth-3.
- 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
PPG-3 Myreth-3 is a synthetic polymer derived from propylene glycol and myristyl alcohol. It belongs to a class of ingredients called emulsifiers, which allow water and oil to mix into a smooth, stable cream or lotion.
How it works
In a cosmetic product, PPG-3 Myreth-3 sits at the boundary between oil and water droplets, reducing surface tension so they stay blended. This prevents the product from separating into layers. It also has mild cleansing properties, helping to remove excess oil and impurities from the skin or hair.
Pros
Effective emulsifier
Keeps oil and water mixed so your product stays smooth and doesn't separate.
Mild surfactant
Provides gentle cleansing without being overly harsh on normal skin.
Cons and cautions
Synthetic ingredient
Not naturally derived, which may be a concern for those seeking plant-based or minimal-ingredient routines.
Potential dryness
In high concentrations, it can strip natural oils, leading to dryness or irritation for sensitive skin types.
Best for
- People using conventional cleansers and shampoos
- Those looking for stable, well-mixed products
Use caution if
- Individuals with very dry or compromised skin who prefer gentler, non-synthetic emulsifiers
Usage tips
Safety summary
PPG-3 Myreth-3 is generally recognized as safe for cosmetic use at low concentrations. It has low irritation and comedogenic potential, though very sensitive skin may react to high amounts.
Research notes
Limited peer-reviewed studies specifically on PPG-3 Myreth-3, but it is a well-established ingredient in the cosmetics industry. Safety assessments by the Cosmetic Ingredient Review (CIR) have found it safe as used.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of a formula
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with no known restrictions at typical usage levels.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- As a synthetic polymer, its biodegradability is limited; it may persist in water systems longer than natural alternatives.
Good to know
- PPG-3 Myreth-3 is often used alongside other emulsifiers to create a balanced formula.
- It is considered safe by major regulatory bodies when used within typical concentrations.
