Common Name(s): Polyglyceryl-3 stearate/oleate/dimer dilinoleate crosspolymer

DESCRIPTION

What It Does: Creates stable w/o emulsions with silicone-elastomer-like texture from a naturally-derived crosslinked emulsifier.

Why It's Used: Used as a natural alternative to silicone elastomers in w/o emulsions; the dimer acid crosslinks create an elastomeric texture.

How It Works: Crosslinked ester polymer from polyglyceryl-3 stearate/oleate with dimer dilinoleic acid crosslinks forms elastomeric network providing silicone-like texture.

Typically Found In: Premium w/o emulsions,natural luxury skin care,silicone-alternative formulas

SOURCING & ETHICS

Vegan Status: Conditional - feedstock declaration required

Halal Status: Unverified - feedstock declaration required (plant, animal and petrochemical routes all exist)

Source Notes: Polyglyceryl-3 from vegetable glycerol; stearate/oleate from plant; dimer acid from plant linoleic; naturally-derived. [audit 2026-07-29 rev2: origin-dependent: the same inci exists in plant, animal and petrochemical versions and the name does not discriminate. determination requires shariah-panel sign-off.]

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 1/5 – low

Sensitivity Concerns: Generally well tolerated.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile. ewg score: 1.

Works Well With: Other natural emulsifiers

Avoid Combining With: No significant incompatibilities

SCIENTIFIC NOTE

Crosslinked polyglyceryl ester polymers are growing natural-origin alternatives to silicone elastomers; dimer acid crosslinks create a 3d ester network with elastomeric texture.
