Ingredient review
Broccoli Seed Oil Unsaponifiables
INCI: Brassica Oleracea Botrytis Oil Unsaponifiables
A lightweight, plant-derived emollient that mimics silicones and offers antioxidant benefits without clogging pores.
In plain English
This is a special part of broccoli seed oil that has had the fatty acids removed, leaving behind a waxy, non-greasy fraction. It feels silky on skin and hair, similar to silicones, but comes from a vegetable source. It helps soften and smooth without leaving a heavy or sticky feel, and it contains natural antioxidants that can help protect against environmental stress.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
The unsaponifiable fraction of broccoli seed oil, meaning the portion that does not turn into soap when mixed with an alkali. It is rich in phytosterols, tocopherols (vitamin E), and other bioactive compounds that provide emollient and antioxidant properties.
How it works
It forms a thin, breathable film on the skin or hair surface, reducing water loss and improving softness. The phytosterols help calm and support the skin barrier, while the tocopherols neutralize free radicals that can cause premature aging.
Pros
Lightweight feel
Unlike many plant oils, this fraction is very light and non-greasy, making it ideal for those who dislike heavy textures.
Antioxidant support
Contains natural vitamin E and other antioxidants that help defend skin from daily pollution and UV stress.
Cons and cautions
Limited research
Most studies focus on whole broccoli seed oil, so the specific benefits of the unsaponifiable fraction are less documented.
Not a heavy moisturizer
For very dry or dehydrated skin, this ingredient may need to be paired with richer emollients or occlusives.
Best for
- People with oily or combination skin who want lightweight moisture
- Those looking for a plant-based alternative to silicones in hair products
Use caution if
- Individuals with a known allergy to broccoli or Brassicaceae family plants
Usage tips
Safety summary
Considered safe for topical use with a very low risk of irritation or clogged pores. As with any plant-derived ingredient, patch test if you have a known allergy to broccoli or related plants.
Research notes
Broccoli seed oil has been studied for its emollient and antioxidant properties. The unsaponifiable fraction is less researched but is widely used in cosmetics for its sensory benefits. A 2017 study found broccoli seed oil reduced transepidermal water loss and improved skin hydration.
