Ingredient review
PEG-7 Glyceryl Soyate
INCI: PEG-7 Glyceryl Soyate
A gentle, non-stripping surfactant derived from soybean oil that effectively cleanses while respecting the skin barrier.
In plain English
PEG-7 Glyceryl Soyate is a mild cleansing ingredient made from soybean oil and a small amount of polyethylene glycol (PEG). It helps water and oil mix together so that dirt, makeup, and excess oil can be rinsed away easily. Unlike harsh soaps, it cleans without leaving your skin feeling tight or dry, making it a popular choice for sensitive skin and gentle cleansers.

Quick decision guide
Useful, but context matters
PEG-7 Glyceryl Soyate 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 PEG-7 Glyceryl Soyate.
- 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 semi-synthetic surfactant created by reacting glycerin from soybean oil with ethylene oxide (PEG). It belongs to the class of non-ionic surfactants, which are known for being very mild and compatible with other ingredients.
How it works
It reduces the surface tension between water and oil, allowing oily impurities to be lifted off the skin and suspended in water so they can be rinsed away. Because it is non-ionic, it does not carry a charge and is less likely to irritate or disrupt the skin's natural barrier.
Pros
Very gentle on skin
Its non-ionic nature means it cleans without stripping the skin's natural oils, making it ideal for dry or sensitive skin types.
Plant-derived base
Made from soybean oil, it appeals to consumers looking for renewable, plant-based ingredients in their skincare.
Cons and cautions
PEG processing concerns
The manufacturing process uses ethylene oxide, which can leave trace impurities if not properly purified. High-quality cosmetic grades are considered safe.
Limited cleansing power
It may not fully remove heavy, long-wear makeup or very water-resistant sunscreens on its own, often requiring a double-cleanse step.
Best for
- People with dry or sensitive skin who need a gentle cleanser
- Anyone looking for a sulfate-free cleansing option
Use caution if
- Those with a known allergy to soy or soybean-derived ingredients (rare, but possible)
Usage tips
Safety summary
PEG-7 Glyceryl Soyate is considered safe for use in cosmetics at typical concentrations. The main safety consideration is the potential for trace impurities from the PEG manufacturing process, but reputable suppliers use purified grades that meet safety standards. It is non-irritating and non-comedogenic for most people.
Research notes
Research on PEG-7 Glyceryl Soyate specifically is limited, but it belongs to a well-studied class of non-ionic surfactants. Studies confirm that non-ionic surfactants are among the mildest for skin and are widely used in gentle cleansers. The Cosmetic Ingredient Review has evaluated similar PEG compounds and found them safe for cosmetic use.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics by the FDA and EU CosIng database. The Cosmetic Ingredient Review (CIR) panel has reviewed PEG compounds and found them safe when used as directed.
- Common uses
- Cleansers, Body washes, Shampoos, Makeup removers
- Environmental note
- Derived from renewable soybean oil and generally biodegradable, though the PEG portion is synthetic and not fully renewable.
Good to know
- PEG-7 Glyceryl Soyate is often used in 'soap-free' cleansers because it creates a light foam without the high pH of traditional soap.
- It is biodegradable and considered environmentally friendlier than some harsher surfactants.
