Ingredient review
PPG-19-Buteth-19
INCI: PPG-19-BUTETH-19
A mild synthetic emulsifier that helps cleansers and shampoos mix oil and water without stripping the skin.
In plain English
PPG-19-Buteth-19 is a man-made ingredient that helps oil and water blend together in products like cleansers and shampoos. It works as a gentle surfactant, meaning it helps lift dirt and makeup from your skin so they can be rinsed away. Because it's designed to be mild, it's less likely to cause irritation or dryness compared to harsher cleansing agents.

Quick decision guide
Useful, but context matters
PPG-19-Buteth-19 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-19-Buteth-19.
- 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-19-Buteth-19 is a synthetic polymer surfactant, part of the buteth family, created by reacting propylene glycol and butylene oxide. It is used primarily as an emulsifier and cleansing agent in cosmetic formulations.
How it works
It reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps products like cleansers and shampoos effectively remove oil-based impurities (like sebum and makeup) while remaining water-rinsable.
Pros
Gentle on skin
PPG-19-Buteth-19 is considered a mild surfactant, making it suitable for daily use without causing excessive dryness or irritation.
Effective emulsifier
It helps create stable, smooth formulas that mix oil and water, improving the texture and performance of cleansers and shampoos.
Cons and cautions
Synthetic origin
As a man-made ingredient, it may not be preferred by consumers seeking natural or plant-based alternatives.
Limited long-term data
While generally regarded as safe, there is less independent research on its long-term effects compared to some traditional surfactants.
Best for
- People with normal to oily skin looking for a gentle cleanser
- Those who use makeup or sunscreen and need effective but mild removal
Use caution if
- Individuals with known sensitivity to synthetic surfactants (rare)
- Those strictly avoiding all synthetic ingredients
Usage tips
Safety summary
PPG-19-Buteth-19 is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, and no significant safety concerns have been raised by regulatory bodies.
Research notes
Research on PPG-19-Buteth-19 is limited but consistent with other mild synthetic surfactants. It is generally recognized as safe by cosmetic ingredient review panels, though independent long-term studies are sparse.
Common label clues
- Typical concentration
- Usually 0.5% to 5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database, with no known restrictions at typical concentrations.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- As a synthetic polymer, it may not be readily biodegradable; however, it is used in low concentrations and is not considered a major environmental concern.
Good to know
- PPG-19-Buteth-19 is often found in sulfate-free cleansers as a milder alternative to sodium lauryl sulfate.
- It is not known to clog pores, making it suitable for acne-prone skin.
