Ingredient review
Oleic/Stearic Glycerides Crosspolymer
INCI: OLEIC/STEARIC GLYCERIDES/DIMER DILINOLEATE CROSSPOLYMER
A gentle, plant-derived thickener that helps create a smooth, non-greasy feel in creams and lotions.
In plain English
This ingredient is a modified fat molecule that acts like a thickening and stabilizing agent in skincare products. It helps create a smooth, creamy texture and can form a light, breathable film on the skin to help other ingredients stay put. Because it's derived from fatty acids found in olive oil and other plant oils, it's generally very gentle and unlikely to clog pores.

Quick decision guide
Useful, but context matters
Oleic/Stearic Glycerides Crosspolymer 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 Oleic/Stearic Glycerides Crosspolymer.
- 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 crosspolymer made by chemically linking oleic and stearic glycerides (fatty compounds from plant oils) with dimer dilinoleate (a fatty acid from linoleic acid). This creates a large, stable molecule that thickens and stabilizes formulas.
How it works
In a cosmetic product, it acts as a thickener and emulsion stabilizer. It helps oil and water phases mix smoothly and stay blended, preventing separation. It also forms a thin, flexible film on the skin that can improve the wear of makeup or sunscreen and reduce water loss without feeling heavy.
Pros
Gentle and non-irritating
Derived from plant-based fatty acids, it has a low irritation risk and is unlikely to cause stinging or redness, making it suitable for sensitive skin.
Improves product feel
It gives creams and lotions a silky, spreadable texture without leaving a greasy residue, enhancing the user experience.
Cons and cautions
May feel tacky on oily skin
The film it forms can feel slightly sticky or heavy on very oily skin types, potentially contributing to a shiny look.
Limited independent research
Most safety data comes from manufacturer studies, and there are fewer peer-reviewed studies on this specific crosspolymer compared to more common thickeners.
Best for
- People who prefer lightweight, non-greasy moisturizers
- Those with normal to dry skin looking for a smooth texture
Use caution if
- Individuals with very oily or acne-prone skin who may find film-forming agents too heavy
Usage tips
Safety summary
Generally recognized as safe for cosmetic use. Low irritation and comedogenic risk. No significant safety concerns reported in available literature.
Research notes
Safety data is primarily from manufacturer and regulatory assessments. Peer-reviewed studies on this exact ingredient are limited, but similar crosspolymers have been well-studied and found safe.
Common label clues
- Typical concentration
- 0.5–5%
- Regulatory status
- Approved for use in cosmetics in the EU, US, and other major markets. The Cosmetic Ingredient Review (CIR) panel has evaluated similar glyceride crosspolymers and found them safe at typical use levels.
- Common uses
- Moisturizers, Sunscreens, Foundations, Serums
- Environmental note
- Sourced from renewable plant oils (like olive or sunflower) and is biodegradable, making it a more eco-friendly thickener compared to some synthetic alternatives.
Good to know
- This ingredient is often used in 'natural' or 'green' beauty products because it's derived from plant oils.
- It is biodegradable and not considered a microplastic.
