Ingredient review
Buriti Seed Oil Polyglyceryl-6 Esters
INCI: Mauritia Flexuosa Seed Oil Polyglyceryl-6 Esters
A skin-friendly, plant-based emulsifier that hydrates and stabilizes formulas without clogging pores or causing irritation.
In plain English
This ingredient is made by combining oil from the buriti fruit (a palm tree native to South America) with polyglyceryl-6, a gentle emulsifier derived from glycerin. It helps water and oil mix together in creams and lotions, so the product stays smooth and doesn't separate. At the same time, it softens and moisturizes the skin because the buriti oil is rich in fatty acids and antioxidants like beta-carotene.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

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
A semi-synthetic ester created by reacting buriti seed oil with polyglyceryl-6, producing a mild emulsifier and emollient that is biodegradable and suitable for sensitive skin.
How it works
It reduces surface tension between oil and water, allowing them to form a stable emulsion. On the skin, it spreads easily and forms a light, non-greasy film that locks in moisture and helps other ingredients absorb better.
Pros
Gentle on skin
Polyglyceryl-6 esters are known for being very mild, making this ingredient ideal for sensitive skin or baby care products.
Antioxidant boost
Buriti oil naturally contains beta-carotene and vitamin E, which can help protect skin from environmental stress.
Cons and cautions
Limited research
While buriti oil is well-studied, the specific ester form has less published data on long-term skin effects.
Sustainability concerns
Buriti palm harvesting can be sustainable, but not all sources are certified; look for brands that verify ethical sourcing.
Best for
- People with dry or dehydrated skin looking for a gentle moisturizer
- Those with sensitive or reactive skin who avoid common emulsifiers
Use caution if
- Individuals with a known allergy to palm-derived ingredients (rare)
