Ingredient review
Polyglyceryl-35 Lauryl Ether
INCI: POLYGLYCERYL-35 LAURYL ETHER
A mild, PEG-free emulsifier that creates stable, creamy textures without stripping the skin.
In plain English
Polyglyceryl-35 Lauryl Ether is a gentle emulsifier made from glycerin and lauric acid (a fatty acid from coconut or palm oil). It helps water and oil mix together in creams and lotions, so you get a smooth, stable product. Unlike some older emulsifiers, it doesn't contain PEG (polyethylene glycol) and is considered very mild on the skin, making it a favorite for sensitive-skin formulas.

Quick decision guide
Easy yes for most routines
Polyglyceryl-35 Lauryl Ether 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 Polyglyceryl-35 Lauryl Ether.
- 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 non-ionic emulsifier derived from polyglycerin (a polymer of glycerin) and lauryl alcohol (a fatty alcohol from plant oils). It belongs to the polyglyceryl ester family, known for being gentle and biodegradable.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable emulsion. Its large polyglyceryl head group creates a mild, non-stripping cleansing action, and it helps deliver a creamy, luxurious feel without leaving a greasy residue.
Pros
Gentle on skin
Its large molecular structure means it sits on the skin's surface without penetrating deeply, reducing the chance of irritation or stinging.
PEG-free alternative
For those avoiding PEG compounds due to contamination concerns, this ingredient offers a similar emulsifying power without the potential 1,4-dioxane impurities.
Cons and cautions
Potential palm oil sourcing
Lauric acid is often derived from palm or coconut oil. If not sustainably sourced, it can contribute to deforestation concerns.
Limited high-temperature stability
In very hot climates or during long storage, emulsions made with this ingredient may be less stable than those with synthetic alternatives.
Best for
- People with sensitive or reactive skin
- Those looking for PEG-free or more natural formulations
Use caution if
- Individuals with a known allergy to coconut-derived ingredients (rare)
Usage tips
Safety summary
Polyglyceryl-35 Lauryl Ether is considered very safe for cosmetic use. It has a low irritation and comedogenic risk, and no significant toxicity concerns have been reported in the available literature. It is a well-tolerated alternative to PEG-based emulsifiers.
Research notes
Research on polyglyceryl esters indicates they are mild surfactants with good skin compatibility. Specific studies on polyglyceryl-35 lauryl ether are limited, but the broader class is well-documented for low irritation and biodegradability.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as a generally recognized safe ingredient). No concentration restrictions are typically imposed.
- Common uses
- Cleansers, Moisturizers, Serums, Sunscreens
- Environmental note
- Biodegradable and derived from renewable plant sources. However, if palm-derived, look for RSPO-certified sustainable palm oil to minimize environmental impact.
Good to know
- It is often listed as 'polyglyceryl-35 lauryl ether' on INCI labels, but may appear as part of a blend.
- It is considered a 'green' emulsifier and is commonly used in natural and organic skincare lines.
