Ingredient review
Polyglyceryl-10 Tetradecanedioate
INCI: Polyglyceryl-10 Tetradecanedioate
A mild, multi-tasking emulsifier that helps create stable, lightweight textures while also softening the skin.
In plain English
This ingredient is a helper molecule that allows water and oil to mix smoothly in your skincare products, so they don't separate. It's made from glycerin (a natural humectant) and a plant-derived fatty acid. Because it's gentle and non-irritating, it's often used in sensitive-skin formulas. It also leaves a light, non-greasy feel on the skin.

Quick decision guide
Easy yes for most routines
Polyglyceryl-10 Tetradecanedioate 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 Polyglyceryl-10 Tetradecanedioate.
- 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
Polyglyceryl-10 Tetradecanedioate is a semi-synthetic emulsifier created by combining polyglycerin-10 (a chain of glycerin units) with tetradecanedioic acid (a plant-derived fatty acid). It belongs to the polyglyceryl ester family, known for being mild and biodegradable.
How it works
In a cosmetic product, this molecule positions itself at the boundary between oil and water droplets, reducing surface tension so they blend into a stable emulsion. This prevents the product from separating into layers. Additionally, its fatty acid portion can deposit onto the skin, providing a light conditioning effect that helps maintain softness.
Pros
Gentle on skin
This emulsifier has a very low irritation score, making it ideal for sensitive-skin products and daily-use moisturizers.
Lightweight feel
Unlike some heavy wax emulsifiers, it leaves a non-greasy, silky finish that works well for lotions and gel-creams.
Cons and cautions
Limited research
While safe, there are fewer independent studies on this specific ingredient compared to classic emulsifiers like glyceryl stearate.
Formula-dependent
Its emulsifying power can be influenced by the pH and salt content of the formula, so not all products will feel the same.
Best for
- Anyone looking for a gentle, non-irritating moisturizer or serum
- People with sensitive or reactive skin who want stable, lightweight formulas
Use caution if
- Those with a known allergy to polyglycerin esters (very rare)
Usage tips
Safety summary
Polyglyceryl-10 Tetradecanedioate is considered safe for use in cosmetics. It has a low irritation and comedogenic risk, and no significant safety concerns have been reported in the available literature. It is not a common allergen.
Research notes
Research on polyglyceryl esters as a class supports their safety and mildness. Specific studies on this exact ingredient are limited, but its chemical structure is well-understood and similar to other safe polyglyceryl emulsifiers. It is included in the EU CosIng database with no safety warnings.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and the US FDA (as part of generally recognized safe emulsifiers). No concentration restrictions are typically imposed.
- Common uses
- Moisturizers, Serums, Cleansers, Sunscreens
- Environmental note
- Polyglyceryl esters are generally biodegradable and have a low aquatic toxicity profile, making them a more eco-friendly emulsifier choice.
Good to know
- Polyglyceryl esters are often derived from vegetable glycerin, making them a popular choice for 'clean beauty' formulations.
- This ingredient is biodegradable and considered environmentally friendly compared to some synthetic emulsifiers.
