Ingredient review
PPG-65 PEG-5 Pentaerythrityl Ether
INCI: PPG-65 PEG-5 Pentaerythrityl Ether
A gentle synthetic emulsifier that helps mix oil and water in cleansers and shampoos, with a low risk of irritation.
In plain English
This ingredient is a man-made polymer that helps oil and water blend together in products like face washes and shampoos. It works by reducing the surface tension between different liquids, so the product stays mixed and spreads easily on your skin or hair. Because it is a large molecule, it tends to stay on the surface and is unlikely to penetrate deeply, making it generally gentle.

Quick decision guide
Useful, but context matters
PPG-65 PEG-5 Pentaerythrityl Ether 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-65 PEG-5 Pentaerythrityl Ether.
- 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 synthetic polymer derived from pentaerythritol, modified with propylene oxide (PPG) and ethylene oxide (PEG) chains. It acts as a non-ionic surfactant and emulsifier.
How it works
It lowers the interfacial tension between oil and water, allowing them to form a stable emulsion. In cleansers, it helps lift dirt and oil from the skin so they can be rinsed away without stripping the skin's natural moisture barrier.
Pros
Gentle cleansing
This emulsifier effectively removes oil and makeup without over-stripping the skin, making it suitable for daily use.
Stable formulas
It helps maintain the texture and consistency of products over time, so your cleanser doesn't separate or become watery.
Cons and cautions
Synthetic origin
It is a lab-made ingredient, which may be a turn-off for consumers seeking naturally derived alternatives.
Potential residue
In high concentrations, it can leave a slight film on the skin, which some people may find heavy or sticky.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Anyone using makeup removers or foaming washes
Use caution if
- Those who strictly avoid all synthetic or PEG-based ingredients
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG/PPG ethers and found them safe when formulated properly. Minimal irritation or sensitization potential.
Research notes
Limited direct studies on this specific compound, but the broader class of PEG/PPG ethers is well-studied and regarded as safe. No significant toxicity or irritation concerns have been reported in cosmetic use.
Common label clues
- Typical concentration
- 1–10%
- Regulatory status
- Approved for use in cosmetics in the US, EU, and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable. However, its large molecular size reduces the risk of absorption into aquatic organisms.
Good to know
- The PPG and PEG numbers (65 and 5) indicate the length of the polymer chains, which affect its solubility and mildness.
- This ingredient is not known to be comedogenic, so it is unlikely to clog pores.
