Ingredient review
PPG-30-Buteth-30
INCI: PPG-30-Buteth-30
A reliable synthetic emulsifier that helps water and oil mix, but offers no active skin benefits.
In plain English
PPG-30-Buteth-30 is a man-made ingredient that helps oil and water stay blended together in products like lotions and cleansers. Without it, many creams would separate into watery and oily layers. It doesn't directly moisturize or treat the skin, but it makes the texture smooth and consistent.

Quick decision guide
Useful, but context matters
PPG-30-Buteth-30 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-30-Buteth-30.
- 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 (a long-chain molecule) made from propylene glycol and butyl alcohol. It belongs to a family of ingredients called emulsifiers, which are essential for creating stable, creamy formulas.
How it works
It sits at the boundary between oil and water droplets, reducing surface tension so they mix instead of separating. This creates a uniform, stable emulsion that feels smooth on the skin and spreads easily.
Pros
Effective stabilizer
Keeps oil and water mixed so your product doesn't separate, ensuring you get the same formula every time you use it.
Gentle on skin
Has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive and acne-prone skin.
Cons and cautions
No active benefit
It doesn't hydrate, soothe, or protect the skin — it's purely a texture and stability helper.
Synthetic origin
Made from petrochemical-derived materials, which may be a turn-off if you prefer natural or biodegradable ingredients.
Best for
- Anyone using conventional creams, lotions, or cleansers
- People who prefer stable, consistent product textures
Use caution if
- Those seeking only natural or plant-derived ingredients
- Individuals with known sensitivity to PPG or butyl compounds (rare)
Usage tips
Safety summary
PPG-30-Buteth-30 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential. However, as a synthetic ingredient, it may not be suitable for those seeking exclusively natural formulations.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PPG alkyl ethers like this one are safe in current usage patterns. No significant human or environmental toxicity has been reported at cosmetic levels.
Common label clues
- Typical concentration
- Usually 1–10% of the formula
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No known restrictions at typical use levels.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Sunscreens
- Environmental note
- As a synthetic polymer, it is not biodegradable and may persist in water systems. Some manufacturers are moving toward more eco-friendly alternatives.
Good to know
- PPG-30-Buteth-30 is considered safe by major regulatory bodies when used in typical cosmetic concentrations.
- It is not a preservative, so products containing it still need a preservation system.
