Ingredient review
PPG-1-Ceteth-10
INCI: PPG-1-CETETH-10
A reliable synthetic emulsifier that helps create stable, creamy textures in skincare products.
In plain English
PPG-1-Ceteth-10 is a man-made ingredient that helps water and oil mix together in your skincare products. Without emulsifiers like this, lotions and creams would separate into watery and oily layers. It also helps other ingredients spread evenly on your skin and can improve the feel of a product, making it smoother and less greasy.

Quick decision guide
Useful, but context matters
PPG-1-Ceteth-10 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-1-Ceteth-10.
- 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-1-Ceteth-10 is a synthetic emulsifier derived from cetyl alcohol and propylene glycol. It belongs to a class of ingredients called alkyl ethoxylates, which are widely used in cosmetics to stabilize mixtures of oil and water.
How it works
In a cosmetic formula, PPG-1-Ceteth-10 reduces the surface tension between oil and water, allowing them to form a stable emulsion. This means your lotion or cream stays smooth and doesn't separate. It also acts as a mild surfactant, helping to lift dirt and oil from the skin when used in cleansers.
Pros
Effective emulsifier
Helps oil and water blend into a stable, creamy texture that doesn't separate over time.
Improves skin feel
Makes products feel smoother and less greasy, enhancing the overall user experience.
Cons and cautions
Synthetic origin
Not derived from natural sources, which may be a drawback for those seeking plant-based or natural skincare.
Potential for irritation
At high concentrations, it may cause mild irritation in very sensitive skin, though this is rare in typical formulations.
Best for
- Anyone using lotions, creams, or cleansers
- People who prefer stable, well-formulated products
Use caution if
- Those with known sensitivity to ethoxylated ingredients
- Strict 'no synthetics' skincare purists
Usage tips
Safety summary
PPG-1-Ceteth-10 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with very sensitive skin may experience mild reactions. Regulatory bodies like the FDA and EU CosIng have approved its use.
Research notes
Research on PPG-1-Ceteth-10 is limited, but it belongs to a well-studied class of ethoxylated emulsifiers. Safety assessments by the Cosmetic Ingredient Review (CIR) have found similar ingredients to be safe at typical use levels. No significant toxicity or health concerns have been identified.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with no known restrictions at typical use levels.
- Common uses
- Cleansers, Moisturizers, Lotions, Creams
- Environmental note
- As a synthetic ethoxylate, its biodegradability varies; some ethoxylates can persist in the environment, but PPG-1-Ceteth-10 is generally considered to have low environmental impact at the concentrations used in cosmetics.
Good to know
- PPG-1-Ceteth-10 is considered safe by major regulatory bodies when used as directed.
- It is often used alongside other emulsifiers to create a more stable formula.
