Ingredient review
Bis-Gluconamidoethylaminopropyl Dimethicone
INCI: BIS-GLUCONAMIDOETHYLAMINOPROPYL DIMETHICONE
A gentle, water-soluble silicone that smooths hair and skin without the heavy feel of traditional silicones.
In plain English
This is a silicone ingredient that has been modified with sugar-derived molecules (gluconamide) to make it more water-friendly. Unlike older silicones that can build up and require harsh sulfates to remove, this one rinses out more easily. It coats the hair or skin with a thin, flexible film that reduces friction, adds shine, and helps prevent moisture loss. Think of it as a lightweight, breathable shield that leaves surfaces silky without feeling greasy or sticky.

Quick decision guide
Useful, but context matters
Bis-Gluconamidoethylaminopropyl 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 Bis-Gluconamidoethylaminopropyl 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 combines a silicone backbone with gluconamide groups (derived from glucose). This structure gives it both water-attracting and water-repelling properties, making it a versatile conditioning agent.
How it works
When applied, it forms a thin, even film on the surface of hair or skin. The gluconamide part helps the ingredient spread easily and adhere to the surface, while the silicone part provides slip and smoothness. Because it is partially water-soluble, it does not accumulate as stubbornly as pure dimethicone, so it rinses off more completely with regular shampoo or cleanser.
Pros
Lightweight conditioning
Provides the slip and smoothness of silicone without the heavy, greasy feel that can weigh down fine hair.
Easier to wash out
The gluconamide modification makes it more water-soluble than standard dimethicone, so it rinses out with milder shampoos and reduces the need for harsh sulfates.
Cons and cautions
Potential for minor buildup
While less buildup-prone than pure dimethicone, very fine or low-porosity hair may still experience some accumulation after repeated use.
Less research available
Compared to classic silicones like dimethicone, this modified version has fewer independent studies on long-term effects or environmental impact.
Best for
- People with dry or damaged hair looking for lightweight smoothing
- Those who want silicone benefits but prefer easier wash-out
Use caution if
- Individuals strictly avoiding all silicones (e.g., for curly girl method)
Usage tips
Safety summary
Considered safe for topical use at typical cosmetic concentrations. Low irritation and comedogenic potential. No known serious safety concerns, but long-term environmental data is still emerging.
Research notes
Most evidence comes from manufacturer safety data and formulation studies. Independent peer-reviewed research on this specific molecule is limited, but it is structurally similar to other well-studied silicone conditioning agents.
Common label clues
- Typical concentration
- 0.5% to 5% in rinse-off products; lower in leave-on formulations
- Regulatory status
- Approved for use in cosmetics in the EU, US, and most major markets. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Conditioners, Hair Serums, Leave-in Treatments, Skincare Lotions
- Environmental note
- Silicones in general can persist in the environment, but modified versions like this one may degrade more readily due to the sugar-derived component. However, comprehensive biodegradation data is limited.
Good to know
- This ingredient is often listed near the end of an ingredient list, meaning it is used in low concentrations.
- It is compatible with both sulfate and sulfate-free cleansers.
