Triolein PEG-6 Esters
INCI: TRIOLEIN PEG-6 ESTERS
A gentle synthetic emulsifier that helps mix oil and water, but may not suit those avoiding PEG compounds.
In plain English
Triolein PEG-6 Esters is a man-made ingredient that acts like a bridge between oil and water. In skincare, it helps oils blend into water-based formulas so products feel smooth and rinse off easily. It is often used in cleansers and makeup removers to dissolve makeup and excess oil without leaving a heavy residue.

Quick decision guide
Useful, but context matters
Triolein PEG-6 Esters 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 Triolein PEG-6 Esters.
- 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 ester created by reacting triolein (a natural fat from oils like olive oil) with polyethylene glycol (PEG). The result is a water-soluble emulsifier that stabilizes oil-in-water mixtures.
How it works
Its molecular structure has both water-loving (hydrophilic) and oil-loving (lipophilic) parts. When added to a formula, it surrounds oil droplets and suspends them in water, creating a stable, uniform mixture. This helps products spread easily and rinse off cleanly.
Pros
Effective emulsifier
Stabilizes oil-and-water blends, making cleansers and moisturizers feel smooth and rinse off easily without greasiness.
Low irritation potential
Generally well-tolerated on skin, with a low risk of stinging or redness, even for sensitive skin types.
Cons and cautions
PEG-related purity concerns
Manufacturing can introduce trace impurities like 1,4-dioxane, though reputable brands use purified grades to minimize risk.
Not natural or biodegradable
As a synthetic compound, it does not appeal to those seeking fully natural or eco-friendly formulations.
Best for
- People who use oil-based cleansers or makeup removers
- Those with normal to combination skin looking for gentle cleansing
Use caution if
- Individuals who strictly avoid PEG-derived ingredients due to personal preference or ethical concerns
Usage tips
Safety summary
Triolein PEG-6 Esters is considered safe for cosmetic use at typical concentrations. The main concern is potential contamination with 1,4-dioxane during manufacturing, but reputable suppliers ensure purification. Overall, it poses low irritation and comedogenic risk.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found PEG esters to be safe when formulated to meet purity standards. No significant human or animal studies specifically on Triolein PEG-6 Esters were identified, but its class is well-studied.
Common label clues
- Typical concentration
- Typically 1–5% in rinse-off products, lower in leave-on formulas
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU, and other major markets. Manufacturers are expected to follow purity guidelines to limit impurities like 1,4-dioxane.
- Common uses
- Cleansers, Moisturizers, Makeup removers, Bath oils
- Environmental note
- PEG compounds are generally not readily biodegradable, but they are used in low concentrations and are often removed during wastewater treatment.
Good to know
- Triolein PEG-6 Esters is often listed alongside other PEG esters in ingredient lists; it is not a standalone active ingredient.
- PEG numbers (like 6) indicate the length of the PEG chain, which affects water solubility and mildness.
