What Is Polyglyceryl-6 Dicaprate?
Polyglyceryl-6 Dicaprate is a plant derived ingredient created by linking six glycerin units (hexaglycerol) and attaching two molecules of capric acid, a fatty acid found in coconut and palm kernel oils. The result is a mild, biodegradable diester that is both water friendly and oil loving, which makes it useful for mixing ingredients that normally do not blend well.
The first polyglyceryl esters were developed in the late 20th century as safer, more sustainable alternatives to traditional surfactants. Advances in green chemistry soon led to the commercial use of Polyglyceryl-6 Dicaprate in personal care formulas. To produce it, manufacturers heat glycerin in the presence of a food grade catalyst so the molecules join, then react the resulting hexaglycerol with purified capric acid. This process avoids harsh solvents and yields a product that meets natural and organic certification standards.
Thanks to its gentle profile and strong performance, this ingredient appears in a wide range of cosmetics. You will most often find it in light facial moisturizers, cleansing balms, makeup removers, serums, sheet masks and leave on treatments that target dehydration or dullness. It is also popular in sunscreen lotions and baby care products where mildness is key.
Polyglyceryl-6 Dicaprate’s Cosmetic Benefits/Uses
In skin care formulas Polyglyceryl-6 Dicaprate serves a single yet important role.
As an emulsifying agent it binds oil and water into a stable uniform mixture so the product feels smooth and stays blended over time. This improves texture, prevents separation and helps active ingredients spread evenly across the skin for consistent results.
Who Can Use Polyglyceryl-6 Dicaprate
This emulsifier is considered gentle enough for all skin types, including sensitive, oily, combination, normal and dry skin. Its lightweight feel and low oil content mean it will not leave a greasy residue, making it comfortable for acne-prone or easily congested complexions. There are no known concerns for reactive or highly sensitized skin beyond the general caution that any ingredient can trigger an individual allergy.
Polyglyceryl-6 Dicaprate is made from plant sourced glycerin and capric acid so it is suitable for vegans and vegetarians. No animal by-products or animal testing are needed to produce it.
Current safety data show no issues for people who are pregnant or breastfeeding when the ingredient is used topically in cosmetic concentrations. This is not medical advice and anyone who is expecting or nursing should discuss all personal care products with a qualified healthcare provider to be extra careful.
The ingredient does not make skin more sensitive to sunlight and has no known interactions with UV exposure. It is also free from common allergens such as gluten soy and nuts.
Potential Side Effects/Adverse Reactions
Reactions to topical Polyglyceryl-6 Dicaprate vary from person to person. The following is a list of potential side effects but most users will not experience any problems when the ingredient is properly formulated and used as directed.
- Mild skin irritation such as temporary redness or stinging
- Allergic contact dermatitis in individuals allergic to glycerin derivatives
- Eye irritation if the product accidentally gets into the eyes
- Rare clogged pores when used in very heavy formulations on highly acne-prone skin
If any discomfort or unusual reaction occurs stop using the product and consult a healthcare professional.
Comedogenic Rating
Polyglyceryl-6 Dicaprate scores a 1 on the comedogenic scale, meaning it is considered very unlikely to clog pores. Its large, water-attracting polyglycerin backbone keeps the molecule lightweight and easily rinsed from the skin, while the two small capric acid tails are less greasy than longer chain fatty acids that often cause congestion. Most acne-prone individuals should tolerate it well, though exceptionally heavy or occlusive formulas that contain a high percentage of this ester could still feel too rich for some.
In short, this ingredient is generally suitable for breakout-prone skin.
Summary
Polyglyceryl-6 Dicaprate is a plant based emulsifier that unites oil and water so lotions, creams and cleansers stay smooth and stable. It performs this job by using its water loving glycerin chain to interact with the aqueous phase and its oil loving capric acid ends to anchor into the lipid phase, creating a uniform blend that spreads evenly across the skin.
The ingredient has gained steady popularity in modern formulations thanks to its gentle nature, biodegradable profile and compatibility with natural certification standards, though it remains less well known to shoppers than classic emulsifiers like polysorbates.
Safety studies and real-world use show a very low risk of irritation, sensitization or pore blockage. As with any new cosmetic it is wise to perform a quick patch test when trying products that contain Polyglyceryl-6 Dicaprate to confirm personal tolerance.
