Ingredient review
Sodium Rapeseedate
INCI: Sodium Rapeseedate
A mild, plant-derived cleanser that effectively removes dirt and oil without stripping the skin's natural moisture barrier.
In plain English
Sodium Rapeseedate is a soap-like ingredient made from rapeseed oil (canola oil). It works as a gentle cleanser, helping to wash away dirt, oil, and makeup from your skin. Unlike some harsh soaps, it tends to be less drying and can leave skin feeling soft rather than tight. It's often found in cleansers for sensitive or dry skin.

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 Sodium Rapeseedate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
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
Sodium Rapeseedate is the sodium salt of fatty acids derived from rapeseed oil. It is a natural surfactant that creates a mild lather and helps water mix with oil and dirt so they can be rinsed away.
How it works
In a cosmetic product, Sodium Rapeseedate reduces the surface tension of water, allowing it to penetrate oils and lift impurities from the skin. It forms micelles that trap dirt and oil, which are then rinsed off with water. Its mild nature means it cleanses without disrupting the skin's protective barrier as much as stronger surfactants.
Pros
Gentle on skin
Sodium Rapeseedate is much milder than traditional soaps, making it ideal for daily use on sensitive or dry skin without causing irritation or tightness.
Plant-derived
Sourced from rapeseed oil, it is a renewable and biodegradable ingredient, appealing to eco-conscious consumers.
Cons and cautions
Lower foaming
It produces a modest lather compared to synthetic surfactants, which may not satisfy those who prefer a rich, bubbly cleanser.
Limited efficacy on heavy makeup
It may struggle to remove long-wear or waterproof makeup in a single cleanse, often requiring a double-cleansing routine.
Best for
- People with dry or sensitive skin
- Those looking for a gentle, non-stripping cleanser
- Individuals seeking plant-based skincare options
Use caution if
- Those with very oily skin who prefer a stronger, foaming cleanser
- Anyone with a known allergy to rapeseed or canola oil (rare)
Usage tips
Safety summary
Sodium Rapeseedate is considered safe for use in cosmetics. It has a low irritation and comedogenic risk, making it suitable for most skin types, including sensitive skin. Allergic reactions are rare.
Research notes
While specific studies on Sodium Rapeseedate are limited, the fatty acids it is derived from (e.g., oleic, linoleic) are well-studied and known to be safe and mild for topical use. Its performance as a surfactant is supported by its widespread use in gentle cleansers.
Common label clues
