What it is
Methyl 2,6-dihydroxybenzoate is a synthetic ester derived from benzoic acid. It is used in cosmetics as a fragrance component and to support the preservative system, helping to prevent microbial growth.
How it works
In a cosmetic product, this ingredient contributes to the overall scent profile and works alongside other preservatives to keep the formula stable and free from bacteria and mold. It does not actively kill microbes on its own but enhances the effectiveness of the main preservative system.
Pros
Enhances product scent
Adds a pleasant aroma to skincare and beauty products, improving the user experience.
Supports preservation
Helps the main preservatives work more effectively, extending the shelf life of the product.
Cons and cautions
Irritation risk
Can cause redness, itching, or stinging in people with sensitive skin or fragrance allergies.
Limited function
Its primary role is fragrance and preservation support, so it offers no direct skin benefit like hydration or anti-aging.
Best for
- People who enjoy scented products and have no history of fragrance allergies
- Those with normal to oily skin that tolerates synthetic fragrances
Use caution if
- Individuals with sensitive skin or known fragrance allergies
- People with eczema or rosacea who may react to aromatic compounds

Research notes
Limited peer-reviewed studies exist specifically on this compound in cosmetics. It is structurally related to other benzoate esters that have been evaluated for skin sensitization. The Cosmetic Ingredient Review (CIR) has assessed similar benzoates and found them safe at low levels, but direct data on this exact ester is sparse.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1%
- Regulatory status
- Approved for use in cosmetics in the EU and US at low concentrations, but must be listed on the label as a fragrance allergen if present above certain thresholds in the EU.
- Common uses
- Fragranced products, Preserved formulations
- Environmental note
- As a synthetic compound, its environmental impact is not well-studied, but it is used in very low concentrations in rinse-off and leave-on products.
Good to know
- This ingredient is often listed near the end of the ingredient list, indicating it is used in small amounts.
- It is not a primary preservative but works in synergy with others like phenoxyethanol.
