Ingredient review
Alkyl Glucosidyl Silicone Blend
INCI: C8-12 ALKYL GLUCOSIDYL HYDROXYCYCLOHEXYLETHYL PEG-18/PPG-6 DIMETHICONE
A gentle, silicone-based cleansing and texturizing ingredient that helps products spread smoothly without stripping the skin.
In plain English
This ingredient is a combination of a sugar-derived molecule (alkyl glucoside) and a silicone chain. It helps cleansers and shampoos foam gently, rinse off easily, and leave skin or hair feeling soft rather than tight or dry. It also helps other ingredients spread evenly across the skin.

Quick decision guide
Useful, but context matters
Alkyl Glucosidyl Silicone Blend 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 Glucosidyl Silicone Blend.
- 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 molecule made by attaching a sugar-based head (alkyl glucoside) to a silicone tail (dimethicone) with added water-loving groups (PEG/PPG). This structure allows it to act as both a mild cleanser and a skin conditioner.
How it works
In a formula, this ingredient sits at the boundary between water and oil. It helps lift dirt and oil from the skin so they can be rinsed away, while the silicone portion deposits a thin, non-greasy film that makes skin feel smooth and soft.
Pros
Mild on skin
Unlike harsh sulfates, this ingredient cleans without stripping the skin's natural moisture barrier, making it suitable for daily use.
Improves sensory feel
It gives products a silky, smooth texture and helps them rinse off cleanly, leaving skin soft rather than tight or sticky.
Cons and cautions
Not fully biodegradable
The silicone portion may persist in the environment longer than purely plant-based cleansers, though it is used in low concentrations.
Potential for buildup
In high-use or leave-on products, silicone-based ingredients can sometimes accumulate on hair or skin, requiring a clarifying wash occasionally.
Best for
- People with normal to dry skin who want a gentle cleanser
- Anyone looking for a non-stripping shampoo or body wash
Use caution if
- Those with known sensitivity to silicones or PEG compounds (very rare)
Usage tips
Safety summary
Generally recognized as safe for use in rinse-off cosmetics at typical concentrations. PEG components are purified in quality manufacturing to remove impurities. No significant irritation or allergy concerns reported in the scientific literature.
Research notes
Limited peer-reviewed studies specific to this exact molecule, but its components (alkyl glucosides and dimethicone derivatives) have a long history of safe use in cosmetics. Safety assessments rely on analog data from similar silicone surfactants.
Common label clues
- Typical concentration
- 0.5% to 5%
- 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
- Cleansers, Shampoos, Body washes, Makeup removers
- Environmental note
- The silicone component is not readily biodegradable, but the ingredient is used at low levels and many manufacturers are working on more eco-friendly silicone alternatives.
Good to know
- This ingredient is often found in 'gentle' or 'daily' cleansers marketed for sensitive skin
- It is considered a 'green' silicone alternative because the alkyl glucoside part is plant-derived
