Ingredient review
Black Currant & Olive Oil Esters
INCI: Black Currant Seed Oil/Olive Oil/Aminopropanediol Esters
A gentle, stable emollient that combines the fatty acid benefits of black currant seed oil and olive oil in a non-greasy ester form.
In plain English
This ingredient is a modified oil blend. Black currant seed oil is rich in gamma-linolenic acid (GLA), an omega-6 fatty acid that helps support the skin barrier. Olive oil provides squalene and oleic acid for deep moisturizing. By reacting these oils with aminopropanediol, the ingredient becomes a stable ester that feels lighter and less greasy than the original oils, making it easier to formulate into modern skincare products.

What it is
A semi-synthetic ester created by combining black currant seed oil and olive oil with aminopropanediol, resulting in a stable, skin-friendly emollient.
How it works
It sits on the skin's surface to reduce water loss (transepidermal water loss, or TEWL) while delivering fatty acids that support the skin barrier. The ester form allows it to spread easily and absorb without a heavy, oily feel.
Pros
Lightweight feel
Unlike raw black currant seed oil, this ester is less greasy and absorbs quickly, making it suitable for daytime use and combination skin.
Barrier support
Delivers GLA and oleic acid, which help maintain a healthy skin barrier and reduce moisture loss over time.
Cons and cautions
Potential allergen
If you are allergic to olive oil or black currant, this ingredient could cause irritation. Patch test if you have known sensitivities.
Limited research
While the component oils are well-studied, there are few peer-reviewed studies on this specific ester blend, so its unique benefits are less documented.
Best for
- People with dry or dehydrated skin looking for a lightweight moisturizer
- Those who want the benefits of black currant seed oil without the heavy texture
Use caution if
- Individuals with a known allergy to black currant or olive oil
Usage tips
Safety summary
Considered safe for topical use in cosmetics at typical concentrations. The component oils have a long history of safe use. As with any new ingredient, patch test if you have sensitive skin or known allergies.
Research notes

- 1% to 10%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions.

- Environmental note
- Both black currant seed oil and olive oil are plant-derived, but the esterification process involves synthetic chemistry. Sourcing of olive oil can vary in sustainability.
Good to know

- It is not the same as pure black currant seed oil—the ester form changes how it behaves on skin.
