Ingredient review
Linoleamidopropyl PG-Dimonium Chloride Phosphate
INCI: LINOLEAMIDOPROPYL PG-DIMONIUM CHLORIDE PHOSPHATE
A gentle conditioning ingredient that helps reduce static and improve softness in hair and skin products.
In plain English
This is a synthetic ingredient that helps hair and skin feel softer and smoother. It works by coating the surface of hair strands or skin cells, reducing static electricity and making them easier to comb or touch. It is often used in conditioners and cleansers because it is mild and unlikely to cause irritation.

Quick decision guide
Useful, but context matters
Linoleamidopropyl PG-Dimonium Chloride Phosphate 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 Linoleamidopropyl PG-Dimonium Chloride Phosphate.
- 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 quaternary ammonium compound derived from linoleic acid (an omega-6 fatty acid) and modified with phosphate and propylene glycol groups. It is a cationic surfactant, meaning it carries a positive charge that helps it bind to negatively charged hair and skin surfaces.
How it works
The positively charged part of the molecule attaches to the negatively charged surface of hair or skin, forming a thin film. This film reduces friction, prevents static buildup, and leaves a smooth, conditioned feel. In cleansers, it also helps stabilize foam and improve the sensory experience.
Pros
Excellent static control
Reduces flyaways and makes hair easier to manage, especially in dry climates or after washing.
Gentle on skin
Has a low irritation and comedogenic risk, making it suitable for sensitive skin and daily use.
Cons and cautions
Potential buildup
With frequent use on fine or low-porosity hair, it can accumulate and lead to dullness or limpness.
Synthetic origin
Not derived from natural sources, which may be a drawback for consumers seeking plant-based ingredients.
Best for
- People with dry or damaged hair needing extra conditioning
- Those with sensitive skin who want a mild cleanser or conditioner
Use caution if
- People following a strictly natural or plant-based routine
- Those with very fine hair who may experience buildup
Usage tips
Safety summary
Considered safe for use in cosmetics at typical concentrations. Low irritation and sensitization potential. No known carcinogenicity or reproductive toxicity. Some individuals with very sensitive skin may experience mild irritation, but this is rare.
Research notes
Safety assessments by the Cosmetic Ingredient Review (CIR) panel have found quaternary ammonium compounds like this one to be safe when formulated appropriately. Studies show good conditioning performance with minimal irritation. Long-term environmental impact data is limited.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Conditioners, Hair masks, Leave-in treatments, Body washes, Facial cleansers
- Environmental note
- As a synthetic quaternary ammonium compound, it may not be readily biodegradable. However, it is used in low concentrations and is generally considered safe for aquatic environments at typical usage levels.
Good to know
- Often listed near the middle or end of ingredient lists, indicating moderate use levels.
- Works well in combination with other conditioning agents like fatty alcohols.
