INCI: Polyglyceryl-6 Behenate

A mild, plant-derived emulsifier that creates stable, creamy textures without irritating the skin.

In plain English

Polyglyceryl-6 Behenate is an emulsifier, which means it helps water and oil mix together in a product so they don't separate. It's made from glycerin (a natural moisturizer) and behenic acid (a fatty acid found in oils like rapeseed). Because it's very gentle, it's often used in sensitive-skin formulas and leaves a smooth, non-greasy feel.

Quick decision guide

Easy yes for most routines

Polyglyceryl-6 Behenate 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Polyglyceryl-6 Behenate.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

A semi-synthetic emulsifier produced by esterifying polyglycerin-6 with behenic acid, a long-chain fatty acid derived from plant oils such as rapeseed or moringa.

How it works

It reduces the surface tension between water and oil phases, allowing them to form a stable emulsion. This creates a uniform, creamy texture that spreads easily and helps other ingredients penetrate the skin more evenly.

Pros

Gentle on skin

Polyglyceryl-6 Behenate has a very low irritation risk, making it ideal for sensitive skin and baby care products.

Improves product feel

It creates a smooth, silky texture that spreads easily and doesn't leave a heavy or sticky residue.

Cons and cautions

Limited to emulsion formulas

This ingredient works best in creams and lotions; it's not effective in water-only products like toners or serums without oils.

Less research on long-term effects

While generally considered safe, there are fewer long-term studies on this specific emulsifier compared to older ones like glyceryl stearate.

Best for

  • People with sensitive or reactive skin looking for gentle moisturizers
  • Anyone who prefers lightweight, non-greasy creams and lotions

Use caution if

  • Those with known allergies to glycerin or behenic acid (very rare)

Usage tips

Use in the oil phase of your formulation for best emulsification results.
Combine with a co-emulsifier like cetearyl alcohol for thicker creams.
Store in a cool, dry place away from direct sunlight to maintain stability.

Safety summary

Polyglyceryl-6 Behenate is considered very safe for topical use. It has low irritation and comedogenic potential, and no significant safety concerns have been reported in cosmetic applications.

Research notes

Research supports its role as a mild, effective emulsifier. Studies show it forms stable emulsions with low skin irritation, though long-term absorption data is limited. It is widely accepted by regulatory bodies.
