Ingredient review
Linoleamidopropyl PG-Dimonium Chloride Phosphate Dimethicone
INCI: LINOLEAMIDOPROPYL PG-DIMONIUM CHLORIDE PHOSPHATE DIMETHICONE
A gentle silicone-conditioner hybrid that smooths hair and softens skin without heavy buildup, but its complex name can be intimidating.
In plain English
This ingredient is a hybrid molecule that combines a fatty acid (linoleic acid from oils), a positively charged conditioning group (quaternary ammonium), and a silicone chain. In simple terms, it helps hair feel silky and detangled, and skin feel soft and smooth, while reducing static and frizz. It's designed to deposit a thin, non-greasy film that improves texture and manageability.

Quick decision guide
Useful, but context matters
Linoleamidopropyl PG-Dimonium Chloride Phosphate Dimethicone 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 Dimethicone.
- 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 semi-synthetic polymer that joins a linoleamidopropyl group (derived from linoleic acid, an omega-6 fatty acid), a PG-dimonium chloride phosphate (a quaternary ammonium compound for conditioning), and a dimethicone (silicone) backbone. It is used primarily in rinse-off and leave-on hair and skin products.
How it works
The positively charged quaternary part binds to negatively charged hair or skin surfaces, allowing the silicone and fatty acid chains to deposit evenly. This reduces friction, smooths the cuticle, and provides a soft, non-sticky feel. The silicone adds slip and shine, while the fatty acid helps moisturize and condition.
Pros
Effective detangling
The quaternary ammonium and silicone work together to reduce friction, making wet and dry combing noticeably easier.
Lightweight feel
Unlike some heavy silicones, this ingredient deposits a thin film that doesn't weigh hair down or feel greasy on skin.
Cons and cautions
Silicone content
If you follow a silicone-free routine, this ingredient contains a silicone backbone that may not be compatible with your preferences.
Potential buildup
On very fine or low-porosity hair, repeated use without clarifying shampoo may lead to slight buildup over time.
Best for
- People with dry, damaged, or frizzy hair seeking smoothness
- Those who want a lightweight conditioning boost in leave-in products
Use caution if
- Individuals strictly avoiding all silicones
- Those with very fine, low-porosity hair who may experience buildup with frequent use
Usage tips
Safety summary
Generally recognized as safe for topical use in cosmetics at typical concentrations. The ingredient has low irritation and comedogenic potential. No significant safety concerns have been reported in regulatory or dermatological literature.
Research notes
Evidence is based on manufacturer safety data and general knowledge of quaternary ammonium and silicone conditioning agents. Peer-reviewed studies specifically on this compound are limited, but its components are well-studied and considered safe.
Common label clues
- Typical concentration
- 0.5% to 3%
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and other major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Conditioners, Hair masks, Leave-in treatments, Body washes, Moisturizers
- Environmental note
- As a silicone derivative, its biodegradability is lower than some plant-based conditioners. However, it is used in small amounts and is not considered a major environmental concern in rinse-off products.
Good to know
- This ingredient is often listed near the middle or end of ingredient lists, indicating lower concentrations.
- It is considered gentle and is commonly used in products for color-treated or chemically processed hair.
