Ingredient review
Polyglyceryl-5 Hexastearate
INCI: Polyglyceryl-5 Hexastearate
A mild, plant-derived emulsifier that helps create stable, creamy textures without clogging pores or irritating sensitive skin.
In plain English
Polyglyceryl-5 Hexastearate is a gentle emulsifier made from glycerin (a natural humectant) and stearic acid (a fatty acid found in coconut or palm oil). Its job is to mix water and oil together so your moisturizer or cream stays smooth and doesn't separate. Because it's derived from familiar, skin-friendly ingredients, it's considered very safe and non-irritating, even for sensitive or acne-prone skin.

Quick decision guide
Easy yes for most routines
Polyglyceryl-5 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-5 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 semi-synthetic emulsifier created by esterifying polyglycerol (a chain of glycerin units) with stearic acid. It belongs to the polyglyceryl ester family, known for being milder than traditional emulsifiers like sodium lauryl sulfate.
How it works
It reduces the surface tension between oil and water, allowing them to form a stable emulsion. This creates a uniform, creamy texture that spreads easily on the skin and helps deliver both water-soluble and oil-soluble ingredients effectively.
Pros
Gentle on skin
Polyglyceryl-5 Hexastearate has a low irritation risk, making it ideal for sensitive skin and daily use products.
Non-comedogenic
It does not clog pores, so it's safe for acne-prone skin and won't contribute to breakouts.
Cons and cautions
Potential tackiness
In high concentrations or in very dry climates, it can leave a slightly sticky or tacky feel on the skin.
Sustainability concerns
It is often derived from palm or coconut oil, which may involve deforestation or habitat loss unless sourced responsibly.
Best for
- Anyone with normal, dry, or combination skin
- People with sensitive or reactive skin
- Those looking for a non-comedogenic emulsifier
Use caution if
- Individuals with a known allergy to stearic acid or glycerin derivatives (rare)
Usage tips
Safety summary
Polyglyceryl-5 Hexastearate is considered very safe for cosmetic use. It has low irritation and comedogenic potential, and no significant toxicity concerns have been reported in standard safety assessments.
Research notes
Safety evaluations by the Cosmetic Ingredient Review (CIR) panel have concluded that polyglyceryl esters are safe as used in cosmetics. Studies show they are mild to the skin and eyes, with no evidence of sensitization or phototoxicity.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics worldwide, including by the FDA (USA) and the European Commission. No concentration restrictions are typically imposed.
- Common uses
- Moisturizers, Creams, Lotions, Cleansers
- Environmental note
- Derived from renewable plant sources, but sustainability depends on the sourcing of palm or coconut oil. Look for RSPO-certified palm oil or coconut oil from sustainable farms.
Good to know
- Polyglyceryl esters are often used in 'clean beauty' formulations because they are considered milder than ethoxylated emulsifiers.
- This ingredient is not a preservative, so products containing it still require a proper preservation system.
