Ingredient review
Hydrogenated Brassica Alcohol
INCI: Hydrogenated Brassica Alcohol
A gentle, plant-based fatty alcohol that softens skin and improves product texture without common irritation.
In plain English
Hydrogenated Brassica Alcohol is a fatty alcohol made from rapeseed (canola) oil. Unlike drying alcohols (like SD alcohol), fatty alcohols are waxy, soothing, and help moisturize the skin. In products, it acts as an emollient—meaning it fills in tiny gaps between skin cells to make the surface feel smoother and softer. It also helps thicken creams and lotions so they spread nicely without feeling greasy.

Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Hydrogenated Brassica Alcohol.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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
A hydrogenated (saturated) fatty alcohol derived from Brassica plants, primarily rapeseed. It is a white, waxy solid at room temperature and is used to improve the feel and stability of cosmetic formulations.
How it works
It sits on the skin's surface, forming a thin, protective layer that reduces water loss (transepidermal water loss, or TEWL—the moisture that evaporates from your skin). This helps keep skin hydrated. It also gives creams a rich, silky texture and helps other ingredients mix together smoothly.
Pros
Gentle on skin
Unlike short-chain alcohols that can sting or dry, Hydrogenated Brassica Alcohol is a fatty alcohol that soothes and softens, making it suitable for sensitive skin.
Improves product feel
It gives creams and lotions a luxurious, silky texture without leaving a greasy residue, so your moisturizer glides on smoothly.
Cons and cautions
Potential heaviness for oily skin
In high concentrations, it may feel too rich for very oily or acne-prone skin, though it is generally non-comedogenic.
Rare allergen risk
While extremely uncommon, people with a specific allergy to rapeseed could react; always patch test if you have known plant allergies.
Best for
- Anyone looking for a gentle, non-irritating moisturizer ingredient
- People with dry or normal skin who want richer creams
- Those who prefer plant-derived ingredients over synthetic alternatives
Use caution if
- Individuals with a known allergy to rapeseed or canola oil (extremely rare)
Usage tips
Safety summary
