Score terms in plain English

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

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

What it is

A semi-synthetic emulsifier created by reacting fatty acids from safflower oil and palm oil with aminopropanediol, a small organic compound. The result is a molecule that has both water-loving and oil-loving parts, making it ideal for blending oil and water phases in cosmetic formulas.

How it works

When you apply a cream containing this ingredient, it helps the product spread evenly across your skin. The emulsifier molecules arrange themselves at the boundary between oil and water droplets, preventing them from separating. This creates a stable, uniform mixture that feels smooth and non-greasy when applied.

Pros

Gentle on skin

This emulsifier has a low irritation risk and is unlikely to clog pores, making it suitable for sensitive and acne-prone skin types.

Improves product feel

It helps creams and lotions feel silky and smooth on the skin, without leaving a heavy or greasy residue.

Cons and cautions

Sustainability concerns

Palm oil sourcing can be linked to deforestation and habitat loss, so look for products with certified sustainable palm oil if this matters to you.

Limited independent research

While safe for use, there are few peer-reviewed studies specifically on this ingredient's long-term effects on skin health.

Best for

  • Anyone looking for a gentle, plant-derived emulsifier in their moisturizer
  • People with normal to dry skin who want a smooth, non-greasy texture

Use caution if

  • Those with a known allergy to safflower or palm oil derivatives

Usage tips

Use products containing this ingredient as part of your daily moisturizing routine, applying after serums and before sunscreen.
Store creams and lotions in a cool, dry place to maintain the stability of the emulsifier system.

Safety summary

This ingredient is considered safe for use in cosmetics at typical concentrations. It has low irritation and comedogenic potential, making it suitable for most skin types. As with any ingredient, patch test if you have sensitive skin or known allergies.
