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 ester made from behenyl alcohol (from rapeseed oil), dimer dilinoleic acid (from sunflower oil), glycerin, and phytosterols (from plant oils). It forms a lightweight, non-occlusive film on the skin.

How it works

It spreads easily over the skin, forming a thin, breathable barrier that reduces water evaporation (transepidermal water loss, or TEWL). This helps keep skin hydrated and supple. The phytosterol component may also support the skin's natural barrier function.

Pros

Gentle on skin

Rated low for both irritation and comedogenicity, making it a safe choice for sensitive or acne-prone skin.

Improves skin feel

Leaves a silky, non-greasy finish that helps makeup apply smoothly and reduces dryness flakes.

Cons and cautions

May feel heavy for oily skin

While non-comedogenic, the film-forming nature can feel too rich for those with very oily skin, especially in humid climates.

Limited independent research

Most evidence comes from manufacturer studies; peer-reviewed data on this specific complex is sparse.

Best for

  • People with dry or dehydrated skin looking for a gentle moisturizer
  • Those with sensitive or reactive skin who want a low-irritation emollient

Use caution if

  • Individuals with extremely oily or acne-prone skin may prefer lighter humectants like glycerin

Usage tips

Apply to slightly damp skin to help the emollient spread evenly and lock in extra moisture.
Use in your nighttime routine for deeper conditioning, or layer under sunscreen in the morning.

Safety summary

Considered safe for cosmetic use. Low irritation and comedogenic potential. No significant safety concerns reported in standard use concentrations.
