What it is

A semi-synthetic ester created by reacting andiroba oil (from the Carapa guaianensis tree) with polyglycerin-6, producing a mild emulsifier that is gentle on the skin.

How it works

It reduces the surface tension between oil and water, allowing them to form a stable, creamy mixture. It also deposits a thin, conditioning film on the skin, helping to lock in moisture without clogging pores.

Pros

Gentle emulsifier

It helps blend oil and water without harsh chemicals, making creams and lotions feel smooth and stable.

Skin conditioning

Leaves a light, moisturizing film that helps keep skin soft without feeling heavy or sticky.

Cons and cautions

Limited research

There are fewer studies on this specific ester compared to more common emulsifiers, so long-term effects are less documented.

Potential allergen

If you have a known allergy to andiroba oil or polyglycerin, this ingredient could cause irritation.

Best for

  • Anyone looking for a gentle, plant-derived emulsifier in their moisturizers or cleansers
  • People with normal to combination skin who prefer non-greasy textures

  • Those with known allergies to andiroba oil or polyglycerin compounds

Usage tips

Use in leave-on products like moisturizers for best conditioning benefits.
Start with lower concentrations if you have sensitive skin to test tolerance.
Store products containing this ingredient in a cool, dry place to maintain stability.

Safety summary
