PPG-12-Buteth-16
INCI: PPG-12-Buteth-16
PPG-12-Buteth-16 is a gentle synthetic emulsifier that helps mix oil and water in products, with a low risk of irritation or clogged pores.
In plain English
PPG-12-Buteth-16 is a man-made ingredient that acts like a bridge between oil and water. In your skincare, it helps keep the formula smooth and stable so the product doesn't separate. It's often used in cleansers and lotions to create a nice texture and help the product spread easily on your skin.

Quick decision guide
Useful, but context matters
PPG-12-Buteth-16 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-12-Buteth-16.
- 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-12-Buteth-16 is a synthetic polymer made from propylene glycol and butylene glycol. It belongs to a family of ingredients called alkoxylated alcohols, which are used as emulsifiers and surfactants in cosmetics.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps create a uniform, creamy texture in products and improves spreadability on the skin.
Pros
Gentle on skin
PPG-12-Buteth-16 has a low irritation risk, making it suitable for most skin types, including sensitive skin.
Non-comedogenic
It does not clog pores, so it's safe for acne-prone skin when used in typical concentrations.
Cons and cautions
Synthetic origin
It is a man-made ingredient, which may be a concern for those seeking natural or clean beauty products.
Limited long-term data
There is less independent research on its long-term effects compared to more common emulsifiers.
Best for
- People with normal to oily skin
- Those using lightweight lotions or gel-creams
Use caution if
- Those strictly avoiding synthetic ingredients
- Individuals with known sensitivity to PEG or PPG compounds
Usage tips
Safety summary
PPG-12-Buteth-16 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, but individuals with sensitivities to synthetic emulsifiers should patch test first.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found PPG and buteth compounds to be safe in cosmetics. However, specific long-term studies on PPG-12-Buteth-16 are limited.
Common label clues
- Typical concentration
- Typically used at 1–5% in rinse-off products, lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US, EU, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PPG and buteth compounds and found them safe at typical concentrations.
- Common uses
