What Is Polyglyceryl-10 Dodecabehenate?
Polyglyceryl-10 Dodecabehenate is an ingredient made by joining ten linked glycerin units with behenic acid, a long chain fatty acid that can be sourced from plant oils such as rapeseed or peanut. The result is a gentle, plant-derived molecule known as a polyglycerol ester. Chemists began exploring these esters in the late twentieth century as a way to replace harsher synthetic emulsifiers in skin care. The manufacturing process typically starts with food-grade glycerin that is polymerized into decaglycerol, then reacted with purified behenic acid under controlled heat and vacuum to form a stable ester without the need for strong solvents.
Thanks to its mild nature and ability to keep oil and water mixed, Polyglyceryl-10 Dodecabehenate shows up in a wide range of products. You will often find it in facial moisturizers, sunscreens, makeup primers, cream cleansers, sheet mask essences and rich body balms where a smooth, non-greasy feel is important.
Polyglyceryl-10 Dodecabehenate’s Cosmetic Benefits/Uses
This ingredient serves as an emulsifying agent, meaning it helps oils and water blend into a uniform, stable mixture. By doing so it prevents products from separating in the jar, improves texture, allows for a lighter skin feel and helps deliver both oil-based and water-based actives evenly across the skin.
Who Can Use Polyglyceryl-10 Dodecabehenate
This gentle emulsifier is generally suitable for every skin type including dry, normal, combination, oily and sensitive. Its lightweight, non clogging texture means even acne-prone skin usually tolerates it well. There are no known reasons for people with eczema, rosacea or easily irritated skin to avoid it unless they have a rare allergy to one of its plant sources.
Because both the glycerin backbone and the behenic acid are typically sourced from plants, Polyglyceryl-10 Dodecabehenate is considered vegan and vegetarian friendly. No animal by-products are used in its standard production.
The ingredient is classed as low risk for pregnant or breastfeeding women when applied topically. Still, this is not medical advice and anyone who is expecting or nursing should show the full product ingredient list to a doctor before use just to be safe.
Polyglyceryl-10 Dodecabehenate is not known to cause photosensitivity so it will not make skin more prone to sunburn. It also plays well with common actives like retinoids, vitamin C and niacinamide without altering their effectiveness.
Potential Side Effects/Adverse Reactions
Responses to any cosmetic ingredient can differ from person to person. The issues listed below are possible yet uncommon when Polyglyceryl-10 Dodecabehenate is used at the levels normally found in skin care formulas.
- Mild redness or irritation in individuals with extremely reactive skin
- Allergic contact dermatitis if someone is sensitized to behenic acid or the plant oil it is sourced from
- Temporary stinging when applied to broken or freshly exfoliated skin
- Clogged pores or surface bumps in very oily skin if used within a heavy balm that also contains other rich lipids
- Eye watering if the raw ingredient gets into the eyes during manufacturing or decanting
If a negative reaction occurs discontinue use and seek advice from a healthcare professional.
Comedogenic Rating
Rating: 1 / 5. Polyglyceryl-10 Dodecabehenate is built on a highly water-friendly glycerin backbone that keeps it from forming a thick, pore-blocking film. While behenic acid on its own is a fatty acid that could feel heavy, turning it into a polyglycerol ester greatly lowers its tendency to sit inside pores. In most formulas it helps oils disperse more evenly rather than pool on the skin, which further trims down clogging risk.
Because of this low rating it is generally fine for people who get acne or frequent breakouts, especially when used in lightweight lotions, gels or milky sunscreens.
Only in very rich balms that pair it with multiple heavy butters could the overall recipe nudge congestion-prone skin, so the full product context matters more than the emulsifier itself.
Summary
Polyglyceryl-10 Dodecabehenate is a plant-derived emulsifier that keeps oil and water blended, improves product texture and helps carry both oil-soluble and water-soluble ingredients evenly across the skin. It does this by combining ten linked glycerin units with behenic acid, creating a molecule that can grab onto both phases and lock them together in a stable mix.
Although it is not a household name like glycerin or hyaluronic acid, it is quietly gaining ground in modern moisturizers, sunscreens and makeup where a smooth non greasy feel is prized, especially within clean beauty and vegan-friendly lines.
Safety profiles rate it as low-risk for irritation or clogging, with no major red flags for pregnancy or sensitive skin. Still, everyone’s skin is unique so it is smart to perform a quick patch test whenever you try a new product containing Polyglyceryl-10 Dodecabehenate or any other unfamiliar ingredient.
