Ingredient review
Alkyl Glucoside Dimethicone
INCI: C6-8 Alkyl C3-6 Alkyl Glucoside Dimethicone
A gentle silicone emulsifier that creates smooth, stable formulas without heavy residue.
In plain English
This ingredient is a hybrid molecule that combines a sugar-based part (glucoside) with a silicone part. The sugar side loves water, and the silicone side loves oil, so it helps mix water and oil together into a stable, creamy product. It's often used in lotions, sunscreens, and makeup to give a silky, spreadable texture that doesn't feel greasy or heavy.

Quick decision guide
Useful, but context matters
Alkyl Glucoside 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 Alkyl Glucoside 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 emulsifier made by attaching short-chain alkyl groups and a glucoside (sugar-derived) head to a dimethicone (silicone) backbone. It is designed to stabilize water-in-oil or oil-in-water emulsions.
How it works
It positions itself at the boundary between water and oil droplets in a formula, reducing surface tension so the two phases mix evenly. The silicone portion provides a smooth, spreadable feel, while the glucoside portion helps the ingredient rinse off more easily than traditional silicones.
Pros
Gentle on skin
Low irritation and comedogenic risk, making it suitable for sensitive and acne-prone skin types.
Improves texture
Creates a smooth, silky feel in creams and lotions without leaving a heavy or sticky residue.
Cons and cautions
Silicone content
Some consumers prefer silicone-free products due to environmental concerns or personal preference, even though this ingredient is generally safe.
Limited biodegradability
As a silicone derivative, it may not break down as quickly in the environment as plant-based emulsifiers.
Best for
- People who want lightweight, silky moisturizers
- Those with normal to combination skin looking for stable emulsions
Use caution if
- Those strictly avoiding all silicones
- Individuals with known silicone sensitivity (rare)
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic potential. No significant safety concerns reported in cosmetic use.
Research notes
Limited peer-reviewed studies specific to this exact molecule, but silicone emulsifiers as a class are well-studied and widely used. Safety assessments by cosmetic ingredient review panels support its use.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics globally, including by the EU CosIng database and US FDA (as part of cosmetic ingredients generally recognized as safe).
- Common uses
- Moisturizers, Sunscreens, Foundations, Serums
- Environmental note
- Silicone derivatives can persist in aquatic environments; however, this ingredient's glucoside portion may improve biodegradability compared to pure dimethicone.
Good to know
- This ingredient is often found in 'silky' or 'velvet' texture products.
- It is considered a 'silicone glucoside,' a newer class of emulsifiers designed to be more rinse-friendly than traditional silicones.
