Ingredient review
PPG-6 Laureth-3
INCI: PPG-6-Laureth-3
An effective emulsifier and mild surfactant, but may cause irritation in sensitive skin at higher concentrations.
In plain English
PPG-6 Laureth-3 is a synthetic ingredient that helps oil and water mix together in products like cleansers and shampoos. It also helps create a nice lather and makes the product spread easily. While it is generally considered safe, it can be slightly drying or irritating for very sensitive skin if used in high amounts.

Quick decision guide
Useful, but context matters
PPG-6 Laureth-3 can be useful, but watch for some irritation potential.
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-6 Laureth-3.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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-6 Laureth-3 is a polyethylene glycol (PEG) derivative combined with lauryl alcohol. It belongs to a class of surfactants that reduce surface tension, allowing oil and water to blend. It is produced synthetically and is commonly used in rinse-off personal care products.
How it works
In a cosmetic product, PPG-6 Laureth-3 acts as an emulsifier, stabilizing mixtures of oil and water so they don't separate. It also functions as a surfactant, helping to lift dirt and oil from the skin or hair so they can be rinsed away. Its mildness makes it suitable for daily cleansing routines.
Pros
Effective emulsifier
Helps create stable, uniform formulas that feel smooth and spread easily on skin and hair.
Mild cleansing action
Provides gentle cleansing without stripping the skin's natural moisture barrier when used at typical concentrations.
Cons and cautions
Potential irritation
At higher concentrations or in leave-on products, it may cause stinging or dryness, especially for sensitive skin types.
Synthetic origin
Derived from petrochemicals, which may be a concern for those seeking natural or biodegradable ingredients.
Best for
- People with normal to oily skin looking for effective daily cleansers
- Those who use conventional shampoos and body washes without sensitivity issues
Use caution if
- Individuals with very dry, irritated, or eczema-prone skin may want to patch-test first
- Anyone seeking a completely natural or PEG-free routine
Usage tips
Safety summary
PPG-6 Laureth-3 is considered safe for use in cosmetics at typical concentrations. It may cause mild irritation in sensitive individuals, especially in leave-on products. Regulatory bodies like the CIR have reviewed similar ingredients and found them safe when formulated properly.
Research notes
Studies on PEG-based surfactants indicate low acute toxicity and skin sensitization potential. However, individual sensitivity varies. The CIR panel has concluded that PEG ethers are safe in rinse-off and leave-on products at concentrations up to 10%.
Common label clues
- Typical concentration
- 1–5% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other regions. The Cosmetic Ingredient Review (CIR) panel has evaluated similar PEG ethers and found them safe at typical use levels.
- Common uses
- Cleansers, Shampoos, Body washes, Conditioners
- Environmental note
- As a synthetic surfactant, it may not be fully biodegradable in all aquatic environments. Some consumers prefer plant-based alternatives for lower ecological impact.
Good to know
- PPG-6 Laureth-3 is often found in sulfate-free cleansers as a milder alternative to sodium lauryl sulfate.
- It is considered biodegradable under certain conditions, but its environmental impact is still studied.
