Ingredient review
Polyglyceryl-6 Hexastearate
INCI: Polyglyceryl-6 Hexastearate
A mild, plant-derived emulsifier that creates stable, creamy textures without stripping the skin.
In plain English
Polyglyceryl-6 Hexastearate is an emulsifier made from glycerin (a natural humectant) and stearic acid (a fatty acid found in cocoa butter and shea butter). Its job is to help water and oil mix together so your lotion or cream stays smooth and doesn't separate. It's considered very gentle and is often used in formulas for sensitive or dry skin because it doesn't foam aggressively or strip natural oils.

Quick decision guide
Easy yes for most routines
Polyglyceryl-6 Hexastearate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Polyglyceryl-6 Hexastearate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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 polyglycerol ester of stearic acid, produced by reacting glycerin with stearic acid to form a molecule with six stearate groups. It is a non-ionic emulsifier, meaning it works without relying on charged particles, making it compatible with a wide range of other ingredients.
How it works
In a cosmetic formula, Polyglyceryl-6 Hexastearate sits at the interface between oil and water droplets, reducing surface tension so the two phases can blend into a stable emulsion. It helps create a rich, creamy texture and can also improve the spreadability and feel of a product on the skin. Because it is non-ionic, it is less likely to cause irritation compared to some other emulsifiers.
Pros
Gentle on skin
Non-ionic structure means it is unlikely to disrupt the skin barrier or cause stinging, even for sensitive or compromised skin.
Stable emulsions
Helps creams and lotions maintain their texture over time, reducing the need for additional stabilizers or preservatives.
Cons and cautions
Limited to emulsifier role
It does not provide active skincare benefits like hydration or exfoliation; its main purpose is texture and stability.
May feel heavy in lightweight formulas
In very thin serums or gel-creams, this ingredient can make the product feel richer than intended, which may not suit oily skin types.
Best for
- People with dry or sensitive skin looking for a rich, gentle moisturizer
- Anyone who prefers products with mild, plant-derived emulsifiers
Use caution if
- Those with a known allergy to stearic acid or glycerin derivatives (very rare)
Usage tips
Safety summary
Polyglyceryl-6 Hexastearate is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for sensitive and acne-prone skin. No significant safety concerns have been reported in regulatory reviews.
Research notes
Polyglycerol esters like Polyglyceryl-6 Hexastearate have been studied for their emulsifying properties and skin compatibility. They are generally recognized as safe by the Cosmetic Ingredient Review (CIR) panel. Research indicates they are mild and well-tolerated, even in formulations for compromised skin.
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. Listed in the CosIng database as a safe emulsifier.
- Common uses
- Moisturizers, Creams, Lotions, Cleansers
- Environmental note
- Derived from renewable plant sources (glycerin and stearic acid). Biodegradable and not known to bioaccumulate.
Good to know
- Polyglyceryl-6 Hexastearate is often used in 'natural' or 'clean' beauty products because it is derived from plant-based glycerin and fatty acids.
- It is biodegradable and generally considered environmentally friendly.
