What Is Polyglyceryl-10 Dicocoate?
Polyglyceryl-10 Dicocoate is a plant-derived ingredient created by linking ten glycerin units with fatty acids that come from coconut oil. Chemically it is known as the diester of coconut acid and polyglycerin-10, giving it both water-loving and oil-loving sections that are valuable in skincare. Its use took off in the early 2000s when brands began looking for alternatives to traditional surfactants that could be labeled gentle and biodegradable. Manufacturers make it through an esterification process where purified coconut fatty acids are reacted with polyglycerin under controlled heat, producing a clear to pale yellow liquid.
You will most often find Polyglyceryl-10 Dicocoate in facial cleansers, micellar waters, cream or milk makeup removers, lightweight lotions, baby washes, and formulations aimed at sensitive skin. It can also appear in modern sheet mask serums and some water-in-oil creams that need a mild emulsifier.
Polyglyceryl-10 Dicocoate’s Cosmetic Benefits/Uses
This ingredient brings two main benefits to a formula
- Cleansing: Its surfactant nature lifts away dirt, sunscreen, and excess oil without stripping the skin’s natural moisture barrier which makes products feel gentle and non-tightening
- Emulsifying: It helps water and oil mix smoothly so lotions stay stable and clear cleansers rinse off easily leaving no greasy residue
Who Can Use Polyglyceryl-10 Dicocoate
This ingredient is classed as gentle and is generally well tolerated by every skin type including sensitive, dry, mature, combination and oily skin. Its mild cleansing action makes it especially helpful for those whose skin feels tight after washing, while its low film-forming tendency means it does not leave a heavy residue that could bother oilier complexions. At typical use levels it is unlikely to clog pores so even acne-prone users can usually enjoy it. There are no specific skin types that must avoid it unless a person has a known allergy to coconut-derived substances.
Because it is sourced from vegetable glycerin and coconut oil, Polyglyceryl-10 Dicocoate is suitable for both vegetarians and vegans and is not animal derived or animal tested by most reputable suppliers.
Current safety data show no issues for women who are pregnant or breastfeeding when the ingredient is used topically in cosmetics. Still, this is not medical advice and anyone expecting or nursing should consult a qualified health professional before adding new products to their routine, just to be on the safe side.
The molecule does not make skin more sensitive to sunlight so it does not add any extra risk of sunburn. It is also biodegradable which appeals to eco-conscious users.
Potential Side Effects/Adverse Reactions
Reactions to topical Polyglyceryl-10 Dicocoate differ from person to person. The points below cover potential issues yet these outcomes are uncommon when the ingredient is correctly formulated in a product.
- Mild skin irritation such as redness or itching, usually in individuals with an existing sensitivity to coconut derivatives
- Temporary stinging if applied to broken or overly dry skin
- Eye irritation if the product accidentally gets into the eyes
- Very rare cases of contact dermatitis due to an allergic response
- Possible increase in surface oiliness for users who already produce excessive sebum, though this is uncommon
If any uncomfortable reaction occurs stop using the product and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 1/5
Polyglyceryl-10 Dicocoate is highly water dispersible and leaves minimal oily residue, which keeps pore blockage risk low. Although it is derived from coconut fatty acids, the polyglycerin backbone increases solubility and reduces its tendency to sit on the skin, so it is generally suitable for people prone to acne or breakouts. Very oily skin types might still prefer to monitor how their skin responds, but most users will not notice extra congestion.
If you are formulating, remember that the overall comedogenicity of a product depends on the entire ingredient mix and not on a single component.
Summary
Polyglyceryl-10 Dicocoate acts mainly as a gentle cleanser and an emulsifier. Its structure contains both water-loving polyglycerin segments and oil-loving coconut fatty acid segments, allowing it to grab onto dirt and oils then rinse them away while also keeping water and oil phases blended in lotions and milky cleansers.
The ingredient has carved out a modest niche in natural and sensitive-skin formulas as brands look for PEG-free surfactants that are mild, biodegradable and vegan friendly. It is not as ubiquitous as classic PEG emulsifiers yet it is gaining steady traction in micellar waters baby washes and lightweight creams.
Current safety data rate it as low risk for irritation or allergy, and global regulatory bodies allow its use without strict concentration limits. As with any new skincare product it is wise to do a small patch test first to ensure personal compatibility.
