Ingredient review
Dodecyl Gallate
INCI: DODECYL GALLATE
Dodecyl gallate is a synthetic antioxidant that helps preserve cosmetic formulas, but it has limited direct skin benefits and may be unnecessary in well-formulated products.
In plain English
Dodecyl gallate is a lab-made ingredient that stops oils and fats in your skincare products from going bad. It works like a preservative, keeping the product fresh longer. It doesn't actively improve your skin, but it helps the product stay effective. It's used in tiny amounts and is generally considered safe, though some people prefer to avoid synthetic antioxidants.

Quick decision guide
Useful, but context matters
Dodecyl Gallate 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 Dodecyl Gallate.
- 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
Dodecyl gallate is a synthetic ester of gallic acid, created in a lab. It belongs to a family of compounds called gallates, which are known for their ability to prevent oxidation. In cosmetics, it's added to protect oils and other easily spoiled ingredients.
How it works
Dodecyl gallate works by interrupting the chain reaction of oxidation. When oils in a product are exposed to air, they can start to break down, causing the product to smell bad or change color. Dodecyl gallate donates electrons to free radicals, stopping this process and keeping the product stable.
Pros
Effective preservative
Dodecyl gallate is very effective at preventing oils from oxidizing, which helps your products stay fresh and effective for longer.
Low irritation potential
At the very low concentrations used in cosmetics, dodecyl gallate is unlikely to cause skin irritation or allergic reactions for most people.
Cons and cautions
No direct skin benefit
Unlike some antioxidants, dodecyl gallate doesn't actively improve your skin's appearance or health. Its only job is to protect the product itself.
Synthetic origin
Being lab-made, it may not appeal to those who prefer naturally derived ingredients. Some consumers actively avoid synthetic antioxidants.
Best for
- Anyone using oil-based or lipid-rich products that need extra preservation
- People who prefer products with a longer shelf life
Use caution if
- Those with known allergies to gallates or related compounds
- Individuals seeking exclusively natural or plant-based preservative systems
Usage tips
Safety summary
Dodecyl gallate is considered safe for use in cosmetics at the low concentrations typically used. It has low irritation and sensitization potential. However, as with any ingredient, individuals with known allergies should avoid it.
Research notes
Research on dodecyl gallate primarily focuses on its antioxidant and preservative functions. It is well-studied in the context of food and cosmetic preservation, with a good safety profile at low doses. There is limited research on its direct effects on skin health.
