Ingredient review
PEG-23 Glyceryl Distearate
INCI: PEG-23 Glyceryl Distearate
A reliable synthetic emulsifier that helps create stable, creamy formulas, but may not suit those avoiding PEG compounds.
In plain English
PEG-23 Glyceryl Distearate is a man-made ingredient that acts like a bridge between oil and water. In a moisturizer or lotion, it keeps the formula from separating into oily and watery layers, so you get a smooth, consistent cream every time you use it. The 'PEG' part stands for polyethylene glycol, a chain of molecules that helps the ingredient dissolve in water, while 'glyceryl distearate' is a fatty compound that mixes with oils. Together, they make the product feel rich and spread easily on skin.

Quick decision guide
Useful, but context matters
PEG-23 Glyceryl Distearate 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-23 Glyceryl Distearate.
- 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 synthetic emulsifier created by reacting polyethylene glycol (PEG) with glyceryl distearate, a fatty acid derivative. It belongs to the PEG family of compounds, which are widely used in cosmetics for their ability to blend oil and water.
How it works
When you apply a cream containing PEG-23 Glyceryl Distearate, the ingredient positions itself at the boundary between oil droplets and water. Its water-loving (hydrophilic) PEG chain pulls toward water, while its oil-loving (lipophilic) glyceryl distearate part anchors into oil. This stabilizes the emulsion, preventing separation and giving the product a uniform, silky texture that spreads easily without feeling greasy.
Pros
Excellent emulsifier
Effectively blends oil and water, preventing separation and ensuring a uniform texture in creams and lotions.
Skin-friendly feel
Imparts a smooth, non-greasy finish that makes products pleasant to apply and wear.
Cons and cautions
Synthetic origin
Made from petrochemical-derived PEG, which may not appeal to those seeking natural or minimal-ingredient routines.
Potential trace impurities
Manufacturing can produce trace amounts of ethylene oxide or 1,4-dioxane, though reputable suppliers purify to safe levels.
Best for
- Anyone using standard moisturizers, creams, or sunscreens
- People who want a stable, consistent product texture
Use caution if
- Those who specifically avoid PEG compounds due to personal preference or ethical sourcing concerns
Usage tips
Safety summary
PEG-23 Glyceryl Distearate is considered safe for use in cosmetics at typical concentrations. The main concern is potential contamination with ethylene oxide or 1,4-dioxane during manufacturing, but purified grades used in reputable products are well within safety limits. It has low irritation and comedogenic potential, making it suitable for most skin types.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have concluded that PEG compounds, including PEG-23 Glyceryl Distearate, are safe for use in cosmetics when formulated to minimize impurities. Studies show low acute toxicity and skin irritation. No significant human or animal data specifically for this ingredient were found, but the class is well-studied.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics by the U.S. FDA and the European Commission, with concentration limits generally not specified due to low irritation potential.
- Common uses
- Moisturizers, Creams, Lotions, Sunscreens, Makeup removers
- Environmental note
- PEG compounds are synthetic and not readily biodegradable, but they are used in low concentrations and are not considered major environmental pollutants.
Good to know
- PEG-23 Glyceryl Distearate is often found in 'cream' or 'lotion' textures rather than gels or serums.
- The number '23' refers to the average number of ethylene glycol units in the PEG chain, which affects water solubility.
