Ingredient review
Manketti Oil Polyglyceryl-6 Esters
INCI: SCHINZIOPHYTON RAUTANENII KERNEL OIL POLYGLYCERYL-6 ESTERS
A mild, plant-based emulsifier that helps blend oil and water while leaving skin soft and smooth.
In plain English
This ingredient is a modified version of Manketti nut oil, a traditional African oil rich in fatty acids. By attaching polyglyceryl-6 groups, it becomes water-friendly and can act as an emulsifier—meaning it helps oil and water mix in a lotion or cream. It also stays on the skin to provide light moisture and a silky feel without being greasy.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
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 Manketti (Schinziophyton rautanenii) kernel oil with polyglycerol. The result is a mild, biodegradable emulsifier that also conditions the skin.
How it works
In a formula, its polyglycerol head loves water while its fatty-acid tail loves oil, so it stabilizes oil-in-water emulsions. On skin, the fatty chains deposit a thin, non-occlusive film that reduces water loss and leaves a soft, velvety texture.
Pros
Gentle on skin
Unlike some synthetic emulsifiers, this ingredient has a low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin.
Eco-friendly sourcing
Manketti nuts are harvested from wild trees in Southern Africa, supporting local communities and biodiversity without deforestation.
Cons and cautions
Limited research
Compared to classic emulsifiers like cetearyl alcohol, there are fewer peer-reviewed studies on long-term safety and efficacy for this specific ester.
Not for heavy moisture needs
It provides light conditioning but lacks the occlusive power of petrolatum or shea butter, so very dry skin may need a richer product on top.
Best for
- Anyone looking for a gentle, plant-derived emulsifier in their skincare
- People with normal to combination skin who prefer lightweight textures
Use caution if
- Those with known allergies to Manketti nut or related tree nuts should patch test first
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. Low irritation and comedogenic potential. As with any new ingredient, patch test if you have sensitive skin or nut allergies.
Research notes
Clinical data is limited, but the fatty acid profile (high in linoleic and oleic acids) is well-known for skin barrier support. The polyglyceryl ester form is widely used in 'green' cosmetics with a good safety record.
Common label clues
- Typical concentration
- 1–5% in leave-on products; up to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. Not classified as a hazardous substance under GHS.
- Common uses
- Moisturizers, Cleansers, Serums, Sunscreens
- Environmental note
- Manketti trees grow wild and are drought-resistant, requiring no irrigation or pesticides. The oil is cold-pressed, and the polyglyceryl modification is biodegradable.
Good to know
- Manketti oil is also known as Mungongo oil and has been used traditionally in Southern Africa for skin and hair care.
- This ingredient is often listed as 'Polyglyceryl-6 Mankettiate' on some product labels.
