PPG-5-Buteth-7
INCI: PPG-5-Buteth-7
A synthetic helper ingredient that blends oil and water, generally safe and non-irritating for most skin types.
In plain English
PPG-5-Buteth-7 is a man-made ingredient that helps oil and water mix together in skincare products. It's often used in cleansers and moisturizers to create a smooth, even texture and to help other ingredients spread nicely on your skin. Think of it as a gentle mixing agent that keeps your product from separating.

Quick decision guide
Useful, but context matters
PPG-5-Buteth-7 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-5-Buteth-7.
- 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-5-Buteth-7 is a synthetic polymer made from propylene glycol and butyl alcohol. It belongs to a class of ingredients called emulsifiers, which are essential for combining water-based and oil-based components in a single product.
How it works
It works by reducing the surface tension between oil and water molecules, allowing them to form a stable, uniform mixture. This prevents your lotion or cleanser from separating into layers and ensures a consistent application each time you use it.
Pros
Effective emulsifier
PPG-5-Buteth-7 reliably blends oil and water, preventing product separation and ensuring a consistent texture every time you use it.
Low irritation risk
It has a low irritation and comedogenic rating, making it suitable for most skin types, including sensitive skin, when used in typical concentrations.
Cons and cautions
Synthetic origin
As a lab-made ingredient, it may not appeal to those seeking natural or organic skincare options.
Limited long-term data
While generally considered safe, there is less independent research on its long-term effects compared to some naturally derived emulsifiers.
Best for
- People with normal to combination skin looking for stable, well-formulated products
- Those who prefer non-irritating synthetic emulsifiers over some natural alternatives
Use caution if
- Individuals with known sensitivities to propylene glycol derivatives (rare)
Usage tips
Safety summary
PPG-5-Buteth-7 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, though individuals with rare propylene glycol sensitivities should patch test.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) and other bodies have found PPG compounds to be safe in rinse-off and leave-on products. Direct studies on PPG-5-Buteth-7 are limited, but its chemical class is well-studied.
Common label clues
- Typical concentration
- Typically 0.5% to 5% of the formula
- 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 compounds and found them safe at typical use levels.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Serums
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable. However, it is used in small amounts and is not known to accumulate in the environment.
Good to know
- PPG-5-Buteth-7 is often used alongside other emulsifiers to fine-tune product texture.
- It is not a preservative, so it won't affect product shelf life on its own.
