Ingredient review
Cetyldimethylamine Hydrolyzed Hempseedate
INCI: Cetyldimethylamine Hydrolyzed Hempseedate
A gentle, plant-derived conditioning ingredient that leaves hair soft and skin smooth without heavy buildup.
In plain English
This ingredient is a modified version of hempseed oil, chemically tweaked to make it better at coating hair and skin. It works like a lightweight conditioner, reducing frizz and adding slip without feeling greasy. Because it's derived from hempseed oil, it also brings some of the fatty acids that help support a healthy skin barrier.

Quick decision guide
Useful, but context matters
Cetyldimethylamine Hydrolyzed Hempseedate is generally a lower-concern ingredient when the full formula suits your 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 Cetyldimethylamine Hydrolyzed Hempseedate.
- 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
A cationic (positively charged) conditioning agent made by reacting cetyldimethylamine (a fatty amine) with hydrolyzed hempseed protein. The result is a molecule that sticks to negatively charged hair and skin surfaces, providing conditioning benefits.
How it works
The positive charge on this molecule attracts it to the negative charge on damaged hair and skin. Once attached, it forms a thin, lubricating film that reduces friction, smooths the cuticle, and helps retain moisture. This makes hair easier to comb and less prone to breakage, while skin feels softer.
Pros
Gentle conditioning
Provides noticeable slip and softness without the heavy, waxy feel of some traditional conditioners, making it suitable for daily use.
Plant-derived origin
Sourced from hempseed oil, a renewable resource rich in omega fatty acids, appealing to those seeking more natural ingredients.
Cons and cautions
Potential buildup
Over time, especially with infrequent washing, the cationic film can accumulate, leading to limp or dull hair. Clarifying shampoos can help.
Variable performance
Results depend heavily on hair type and damage level; very porous hair may absorb too much, while low-porosity hair may not benefit as much.
Best for
- People with dry, damaged, or chemically treated hair
- Those looking for a lightweight, non-greasy conditioner
Use caution if
- Individuals with very fine or oily hair who may find any conditioning too heavy
Usage tips
Safety summary
Cetyldimethylamine Hydrolyzed Hempseedate is considered safe for use in rinse-off and leave-on products at typical concentrations. It has low irritation and comedogenic potential, though individuals with very sensitive skin should patch test first.
Research notes
While direct studies on this specific ingredient are limited, the safety of cationic conditioning agents derived from fatty amines and plant proteins is well-established. Hempseed oil itself has documented skin barrier benefits. The ingredient is widely used in commercial hair care products.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
