PPG-3-Buteth-5
INCI: PPG-3-BUTETH-5
A gentle synthetic surfactant that helps cleansers foam and rinse cleanly without stripping the skin.
In plain English
PPG-3-Buteth-5 is a man-made ingredient that helps oil and water mix together in a product. It is often used in cleansers and shampoos to create a nice lather and to help rinse away dirt and makeup without leaving a greasy film. Think of it as a helper that makes your cleanser work better and feel lighter on your skin.

Quick decision guide
Useful, but context matters
PPG-3-Buteth-5 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-3-Buteth-5.
- 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-3-Buteth-5 is a synthetic surfactant (a type of detergent) made from propylene glycol and butyl alcohol. It belongs to a family of ingredients called alkoxylated ethers, which are designed to be mild and effective at reducing surface tension between oil and water.
How it works
In a cosmetic product, PPG-3-Buteth-5 lowers the surface tension between water and oil, allowing them to blend into a stable mixture. This helps the product spread easily, lift dirt and oil from the skin, and rinse away cleanly. It also helps create foam in cleansers and shampoos.
Pros
Mild cleansing
PPG-3-Buteth-5 is considered a gentle surfactant, making it suitable for daily use in cleansers without over-stripping the skin.
Good rinse-off
It rinses cleanly, leaving little to no residue, which helps avoid clogged pores and buildup on the skin or scalp.
Cons and cautions
Synthetic origin
As a lab-created ingredient, it may not appeal to consumers seeking natural or plant-based formulations.
Potential dryness
In high concentrations or in products without enough moisturizing ingredients, it can contribute to a tight or dry feeling after washing.
Best for
- People who use foaming cleansers or shampoos
- Those with normal to oily skin looking for a clean rinse
Use caution if
- Those with very dry or compromised skin barriers may prefer non-foaming cleansers
Usage tips
Safety summary
PPG-3-Buteth-5 is considered safe for use in cosmetics at typical concentrations. It is generally non-irritating and non-sensitizing, though like all surfactants, it can be drying if overused. Regulatory bodies have not flagged significant safety concerns.
Research notes
There is limited published research specifically on PPG-3-Buteth-5, but it is a well-established surfactant in the cosmetics industry. Safety assessments rely on its chemical class (alkoxylated ethers), which have a history of safe use in rinse-off products.
Common label clues
- Typical concentration
- Usually under 5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific concentration restrictions, though typical use is low.
- Common uses
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- As a synthetic surfactant, its biodegradability varies; some alkoxylated ethers are not readily biodegradable, so environmental impact depends on formulation and disposal.
Good to know
- PPG-3-Buteth-5 is often used in combination with other surfactants to create a milder overall cleansing system.
- It is not a common standalone ingredient; you'll usually find it as part of a blend in commercial formulas.
