Lauryl glucoside
A 12-carbon alkyl glucoside that foams a little better than decyl glucoside and carries the same class contact-allergy profile.
What it is
Lauryl glucoside has a 12-carbon tail and is used as a primary or booster surfactant in sulfate-free and baby shampoos and cleansers, and as an emulsifier.
How it works
It forms non-ionic micelles like the other glucosides, and the longer tail gives better foam and cleaning than decyl glucoside.
What the studies show
- In a 19-year patch-test cohort of 11,842 people, 30 reacted to alkyl glucosides, with shampoos among the commonest causal products (Gijbels 2014).
- Patch testing with several glucosides is advised because cross-reaction between them is not automatic (Alfalah 2017).
- A 2026 review compiles reports of allergic contact dermatitis to alkyl glucosides including lauryl glucoside (de Groot 2026).
We found no hair-specific data, so the direct evidence is weak.
Bottom line
The same advice applies as for decyl glucoside: reasonable for dry or sensitive scalps without a known allergy, and best avoided if you have reacted to glucosides.

Gijbels D et al. Allergic contact dermatitis caused by alkyl glucosides. 2014
Result: Causal products were shampoos (12), skin cleansers (12), sunscreens (5) and skin-care products (4); 16 patients had multiple contact allergies.
Read the study ↗Alfalah M et al. Alkyl Glucosides. 2017
Result: Alkyl glucosides were assumed low in irritancy and allergenicity, but cases of allergic contact dermatitis have accumulated since the early 2000s; sensitisation to decyl glucoside is rising in North American data; cross-reactions are common but not automatic.

Result: Alkyl glucosides (mainly decyl, lauryl, cetearyl and coco-glucoside) have low irritation potential but can induce contact sensitisation.
