Ingredient review
PPG-2-Ceteth-10
INCI: PPG-2-CETETH-10
PPG-2-Ceteth-10 is a gentle synthetic emulsifier that helps oil and water mix in your skincare products, with a low risk of irritation.
In plain English
PPG-2-Ceteth-10 is a man-made ingredient that acts like a bridge between oil and water. In your lotion or cleanser, it keeps the formula from separating into layers, so you get a smooth, consistent texture every time you use it. Think of it as a helper that makes sure the oils and water in your product stay blended together.

Quick decision guide
Useful, but context matters
PPG-2-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-2-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-2-Ceteth-10 is a synthetic compound made by combining propylene glycol (PPG) with a fatty alcohol (ceteth) and ethylene oxide. It belongs to a class of ingredients called emulsifiers, which are essential for creating stable mixtures of oil and water in cosmetics.
How it works
In a cosmetic product, PPG-2-Ceteth-10 reduces the surface tension between oil and water molecules, allowing them to mix into a uniform emulsion. This prevents the product from separating into an oily layer and a watery layer, ensuring a consistent texture and performance from first use to last.
Pros
Effective emulsifier
PPG-2-Ceteth-10 reliably blends oil and water, giving your skincare products a smooth, uniform texture that doesn't separate over time.
Low irritation risk
Compared to some other surfactants, this ingredient is considered gentle and unlikely to cause stinging or redness for most skin types.
Cons and cautions
Synthetic origin
If you prefer naturally derived or plant-based ingredients, PPG-2-Ceteth-10 may not align with your preferences since it is fully synthetic.
Limited research
There is not a large body of independent research on this specific ingredient's long-term effects on skin, though it is generally recognized as safe in low concentrations.
Best for
- People who use lotions, creams, or cleansers and want a stable, non-separating formula
- Those with normal to combination skin looking for a gentle emulsifier
Use caution if
- Individuals with known sensitivities to synthetic ethoxylated ingredients (rare)
Usage tips
Safety summary
PPG-2-Ceteth-10 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with rare sensitivities to ethoxylated ingredients should exercise caution.
Research notes
Safety assessments by cosmetic ingredient review panels have found PPG-2-Ceteth-10 to be safe in leave-on and rinse-off products at concentrations up to 5%. Independent clinical studies are limited, but no significant safety concerns have been reported.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) at concentrations typically up to 5%.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Lotions
- Environmental note
- As a synthetic ethoxylated compound, PPG-2-Ceteth-10 may have low biodegradability; however, it is used in small amounts in rinse-off products.
Good to know
- PPG-2-Ceteth-10 is often used alongside other emulsifiers to create a more stable formula.
- It is not a preservative, so products containing it still need a proper preservation system.
