What Is Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters?
Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters is a plant-based ingredient made by joining the rich seed oil of the buriti palm (Mauritia flexuosa) with polyglycerin-6, a chain of six glycerin units. The buriti palm grows in the wetlands of South America where its bright orange fruit has long been used for food, skin care and hair care. When the beauty industry noticed the oil’s high level of beta-carotene and fatty acids, suppliers began to refine and adapt it for modern formulas. Through a process called transesterification, chemists link the oil’s fatty acids to polyglycerin-6, creating a smooth, water-friendly liquid that can blend oil and water without extra surfactants.
The resulting material keeps the nourishing feel of the original oil but gains a lighter texture and better spreading power. You will find it in moisturizers, facial oils, lotions, balms, creamy cleansers, hair conditioners and makeup like foundations or tinted balms where a soft skin finish is desired.
Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters’s Cosmetic Benefits/Uses
This multitasker improves both the feel and stability of a formula.
- Emollient: Softens and smooths the skin surface, helping to reduce dry, rough spots while giving products a silky glide
- Emulsifying: Helps oil and water mix evenly so creams stay stable, resist separation and feel light rather than greasy
Who Can Use Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters
This ingredient is generally well suited to all skin types. Dry and mature skin benefit from its cushioning moisture while normal and combination skin enjoy its light, non-greasy slip. Even sensitive skin tends to tolerate it because it is free of common irritants, although those with very oily or acne-prone skin may want to watch how their skin responds to rich emollients in general.

Comedogenic Rating
Rating: 2 (low)
This score reflects the balance between the original buriti seed oil, which is rich in oleic and palmitic acids that can occasionally block pores, and the added polyglycerin-6 that makes the molecule more water friendly and less likely to sit heavily on the skin. Most people will not notice clogged pores from this ingredient, though those with very oily skin should keep an eye on how their skin reacts.
Overall, Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters is generally fine for acne-prone users but it is not completely risk free for those who break out easily.
Formulation matters too: when used at lower levels in light creams or lotions the chance of congestion drops even more while thick balms that rely on higher amounts may feel heavier.
Summary
Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters works as a two-in-one helper. As an emollient it fills in tiny surface gaps to leave skin soft and smooth, and as a natural-leaning emulsifier it lets water and oil stay mixed so products stay creamy and spread well. It does both jobs thanks to its split personality: the buriti-derived fatty side loves oil while the polyglycerin side loves water, letting it nestle between the two.
The ingredient is still a bit of an insider choice rather than a household name, but its plant origin and pleasing texture are making it pop up more in mid-range and indie formulas.
Safety wise it is considered low risk with only rare reports of irritation or sensitivity. Like any new cosmetic though, it is smart to run a quick patch test when you try a product containing this ingredient just to make sure your skin agrees with it.
