PPG-17-Buteth-17
INCI: PPG-17-BUTETH-17
A safe, synthetic solvent that helps dissolve other ingredients and leaves a light, non-greasy feel on skin.
In plain English
PPG-17-Buteth-17 is a man-made ingredient that acts like a helper in your skincare products. It helps mix ingredients that don't normally blend well (like oil and water) and can make the product feel smooth and light on your skin. Think of it as a behind-the-scenes worker that improves the texture and stability of your cleanser or makeup remover without causing irritation.

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-17-Buteth-17.
- 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 large molecule made of repeating units) created by combining propylene glycol and butylene oxide. It belongs to a family of ingredients called PPG ethers, which are known for their ability to dissolve both water- and oil-soluble substances.
How it works
It acts as a solvent, meaning it helps dissolve other ingredients so they can be evenly distributed in a formula. It also has mild skin-conditioning properties, leaving a soft, non-sticky feel after application. In rinse-off products, it helps remove makeup and sunscreen without stripping the skin's natural oils.
Pros
Gentle on skin
PPG-17-Buteth-17 has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin.
Improves product feel
It helps create a smooth, non-greasy texture in cleansers and makeup removers, so your skin feels clean without a heavy residue.
Cons and cautions
Synthetic origin
As a lab-made ingredient, it may not appeal to consumers who prefer plant-based or naturally derived alternatives.
Limited absorption data
While generally considered safe, there is less public research on how much of this ingredient penetrates the skin compared to more common solvents.
Best for
- People who use heavy makeup or water-resistant sunscreen
- Those with normal to oily skin who prefer lightweight textures
Use caution if
- Individuals with known sensitivity to propylene glycol derivatives
- Those seeking 100% natural or organic skincare
Usage tips
Safety summary
PPG-17-Buteth-17 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant toxicity has been reported in available studies. As with any ingredient, individuals with known sensitivities to propylene glycol derivatives should patch-test first.
Research notes
Research on PPG-17-Buteth-17 specifically is limited, but the broader class of PPG ethers has been evaluated by the Cosmetic Ingredient Review panel, which concluded they are safe for use in rinse-off and leave-on products at concentrations up to 10%. No peer-reviewed studies on long-term skin absorption were identified.
Common label clues
- Typical concentration
- Typically 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics by the U.S. FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has reviewed similar PPG ethers and found them safe at typical use concentrations.
- Common uses
- Cleansers, Makeup removers, Fragrance products
- Environmental note
- As a synthetic polymer, it may not be biodegradable. However, it is used in small amounts and is typically rinsed off, limiting environmental exposure.
Good to know
- PPG-17-Buteth-17 is often found in micellar waters and oil-free makeup removers.
- It is not a fragrance itself but can help stabilize fragrance ingredients in a formula.
