Linum Alticum Amidopropyl Betaine
INCI: LINUM ALTICUMAMIDOPROPYL BETAINE
A gentle, plant-based surfactant that cleanses effectively while being kind to sensitive skin.
In plain English
This ingredient is a mild soap-like molecule made from linseed (flax) oil. It helps water mix with oil and dirt so they can be rinsed away, but it's much less harsh than traditional soaps. Think of it as a gentle cleaner that won't leave your skin feeling tight or dry.

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 zwitterionic surfactant derived from linseed (Linum alticum) oil, chemically modified with a betaine group to create a mild cleansing agent.
How it works
It reduces the surface tension between water and oil, allowing impurities and excess sebum to be emulsified and rinsed away. Its amphoteric nature means it works well in a wide pH range and is less irritating than anionic surfactants like sodium lauryl sulfate.
Pros
Mild on skin
This surfactant is much gentler than traditional soaps, making it ideal for daily use on sensitive or dry skin without causing tightness or irritation.
Plant-based origin
Derived from linseed oil, it appeals to consumers seeking natural, renewable ingredients in their skincare routine.
Cons and cautions
Lower foam volume
It produces a less rich lather compared to harsher cleansers, which some users may perceive as less effective even though it cleans just as well.
Limited research
There are fewer published studies on this specific ingredient compared to more common betaines, so long-term data is less robust.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals with known flaxseed allergy (rare)
Usage tips
Safety summary
