Ingredient review
PPG-1 Beheneth-15
INCI: PPG-1 BEHENETH-15
A gentle synthetic emulsifier that helps mix water and oil in your products, with a low risk of irritation or clogged pores.
In plain English
PPG-1 Beheneth-15 is a man-made ingredient that helps oil and water stay blended together in creams, lotions, and cleansers. Without it, your moisturizer would separate into a watery layer and an oily layer. It also helps other ingredients spread evenly on your skin. It is considered very gentle and unlikely to cause breakouts or stinging.

Quick decision guide
Useful, but context matters

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 Beheneth-15.
- 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 Beheneth-15 is a synthetic polymer derived from behenyl alcohol (a fatty alcohol from plants) and propylene oxide. It belongs to a class of ingredients called emulsifiers, which are essential for creating stable, creamy products.
How it works
This molecule has one end that loves water and another that loves oil. When you shake or mix a product, PPG-1 Beheneth-15 positions itself at the boundary between oil and water droplets, preventing them from separating. This keeps your lotion smooth and uniform from first use to last.
Pros
Gentle on skin
PPG-1 Beheneth-15 has a very low irritation score in safety assessments, making it suitable for sensitive skin types.
Improves product texture
It helps create smooth, creamy formulas that feel pleasant on the skin and don't separate over time.
Cons and cautions
Synthetic origin
It is manufactured in a lab, which may be a concern for people seeking only natural or plant-derived ingredients.
Limited independent research
Most safety data comes from industry-sponsored studies, and there is less public research on long-term skin effects compared to some natural emulsifiers.
Best for
- Anyone using moisturizers or cleansers who wants a stable, well-mixed product
- People with sensitive skin who need gentle emulsifiers
Use caution if
- Those who strictly avoid all synthetic ingredients in their skincare routine
