Ingredient review
Polysorbate 80 Dicinnamate
INCI: Polysorbate 80 Dicinnamate
A gentle emulsifier with antioxidant potential, but research on its skin benefits is still limited.
In plain English
Polysorbate 80 Dicinnamate is a lab-made ingredient that helps oil and water mix in creams and lotions. It also has antioxidant properties, meaning it can help protect your skin from damage caused by free radicals (unstable molecules from pollution or UV rays). However, it's not as well-studied as other common antioxidants like vitamin C or E.

Quick decision guide
Useful, but context matters
Polysorbate 80 Dicinnamate 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 Polysorbate 80 Dicinnamate.
- 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
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic compound created by combining polysorbate 80 (a common emulsifier) with dicinnamate (derived from cinnamic acid, found in cinnamon). It serves dual roles as an emulsifier and antioxidant.
How it works
As an emulsifier, it reduces surface tension between oil and water, allowing them to blend into a stable cream or lotion. As an antioxidant, it donates electrons to neutralize free radicals, potentially preventing oxidative damage to skin cells.
Pros
Dual function
Works as both an emulsifier and antioxidant, potentially simplifying formulas.
Low irritation risk
Generally considered gentle on skin, with low reported irritation in cosmetic use.
Cons and cautions
Limited research
Most evidence comes from lab studies; human skin benefits are not yet well-documented.
Redundant in some formulas
If a product already contains proven antioxidants, this ingredient may add little extra benefit.
Best for
- Anyone using oil-and-water based creams who wants added antioxidant support
- People with normal to dry skin looking for stable, well-mixed moisturizers
Use caution if
- Those with known sensitivities to polysorbates or cinnamic acid derivatives
Usage tips
Safety summary
Polysorbate 80 Dicinnamate is considered safe for topical use at typical cosmetic concentrations. It has low irritation and comedogenic potential, though individuals with rare allergies to polysorbates or cinnamates should patch test.
Research notes
Research is preliminary. In vitro studies suggest antioxidant activity, but peer-reviewed human trials are lacking. More evidence is needed to confirm efficacy in skincare.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for cosmetic use in many regions, including the EU and US, but not specifically reviewed by the Cosmetic Ingredient Review panel as of 2025.
- Common uses
- Moisturizers, Sunscreens, Anti-aging creams
- Environmental note
- Polysorbate derivatives can be slow to biodegrade; however, specific data on this variant is not available.
Good to know
- Polysorbate 80 Dicinnamate is not the same as plain polysorbate 80; the dicinnamate modification adds antioxidant activity.
- It is often used at low concentrations (under 3%) to avoid affecting product texture.
