Ingredient review
PEG-60 Glyceryl Diisostearate
INCI: PEG-60 Glyceryl Diisostearate
A reliable synthetic emulsifier that helps create smooth, stable creams and lotions with low irritation potential.
In plain English
PEG-60 Glyceryl Diisostearate is a man-made ingredient that acts like a bridge between oil and water. In skincare, it helps mix ingredients that normally separate, so your lotion or cream stays smooth and doesn't split into layers. It's a gentle emulsifier, meaning it's unlikely to cause irritation or clog pores for most people.

Quick decision guide
Useful, but context matters
PEG-60 Glyceryl Diisostearate 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-60 Glyceryl Diisostearate.
- 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
PEG-60 Glyceryl Diisostearate is a synthetic compound made by reacting ethylene oxide (PEG) with glyceryl diisostearate, a fatty acid derivative. It belongs to the PEG (polyethylene glycol) family and is designed to stabilize oil-and-water mixtures.
How it works
In a cosmetic product, this ingredient reduces the surface tension between oil and water droplets, allowing them to blend into a uniform emulsion. It also helps improve the texture and spreadability of creams and lotions, making them feel smoother on the skin.
Pros
Gentle on skin
PEG-60 Glyceryl Diisostearate has a low irritation risk, making it suitable for most skin types, including sensitive skin.
Improves product stability
It prevents oil and water from separating, so your moisturizer or cleanser stays effective and consistent throughout its shelf life.
Cons and cautions
Synthetic origin
As a PEG-based compound, it is not natural or biodegradable, which may be a concern for those seeking eco-friendly or clean beauty products.
Potential tackiness at high levels
In formulas with very high concentrations, it can leave a slightly sticky or heavy feel on the skin, though this is rare in typical skincare.
Best for
- People who use creams, lotions, or sunscreens and want a stable formula
- Those with normal to combination skin looking for a gentle emulsifier
Use caution if
- Individuals who strictly avoid PEG-based ingredients due to personal preference
Usage tips
Safety summary
PEG-60 Glyceryl Diisostearate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. Some consumers avoid PEGs due to concerns about ethylene oxide residues, but cosmetic-grade PEGs are purified to meet safety standards.
Research notes
Research on PEG-60 Glyceryl Diisostearate is limited, but it is a well-established emulsifier in the cosmetics industry. Safety assessments by expert panels (e.g., CIR) have found PEG derivatives to be safe in cosmetics when used as intended. No significant adverse effects have been reported in routine use.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng). Generally recognized as safe at typical concentrations.
- Common uses
- Cleansers, Moisturizers, Sunscreens, Makeup removers
- Environmental note
- PEG compounds are synthetic and may not be readily biodegradable. However, they are used in low amounts and are not known to accumulate in the environment.
Good to know
- PEG-60 Glyceryl Diisostearate is often used in combination with other emulsifiers to fine-tune texture.
- The '60' refers to the number of ethylene oxide units, which influences its water-loving properties.
