Summary
Alkyl glucosides, used in cosmetics, can cause allergic contact dermatitis (ACD) despite low predicted allergenicity. Decyl glucoside shows a 2.4% positive reaction rate in U.S. patch testing, often linked to personal care products.
Area of Science:
- Dermatology
- Toxicology
- Cosmetic Science
Background:
- Alkyl glucosides are nonionic surfactants derived from glucose and fatty alcohols, increasingly used in cosmetics due to favorable irritation and ecological profiles.
- Despite chemical stability and lack of reactive sites, alkyl glucosides were not initially predicted to possess allergenic potential.
- Recent findings indicate that alkyl glucosides can induce contact sensitization, a phenomenon gaining recognition.
Purpose of the Study:
- To review the nature, properties, and applications of alkyl glucosides, focusing on contact allergy and allergic contact dermatitis (ACD).
- To analyze patch testing results for alkyl glucosides in routine and selected patient groups.
- To present case series and reports of ACD specifically related to decyl and lauryl glucoside.
Main Methods:
- Literature review of alkyl glucosides, contact allergy, and allergic contact dermatitis.
- Analysis of patch test data from routine testing and specialized patient cohorts.
- Compilation and summary of reported case studies involving ACD from decyl and lauryl glucoside.
Main Results:
- Decyl glucoside demonstrates a 2.4% positive reaction rate in routine patch testing in the United States.
- Over 80% of positive patch test reactions to alkyl glucosides are currently relevant, primarily due to their presence in personal care products.
- Case reports and series confirm ACD induction by decyl and lauryl glucoside, contrary to initial predictions.
Conclusions:
- Alkyl glucosides, particularly decyl and lauryl glucoside, are recognized causes of allergic contact dermatitis.
- The increasing use of alkyl glucosides in cosmetics necessitates awareness of their allergenic potential.
- Further investigation into patient demographics and product-specific reactions is warranted (as detailed in Part 2).

Overview
01:23Protecting Groups for Aldehydes and Ketones: Introduction
Protecting groups are compounds that can bind to a specific functional group in the presence of other functional groups to protect them from undesired chemical reactions. These compounds can selectively bind to particular functional groups and advance chemoselective reactions in polyfunctional systems (Figure 1). After the functional group has served its purpose, it is removed by reacting it with specific compounds.
02:31Protection of Alcohols
This lesson delves into the concept of protection and deprotection of a functional group fundamental to synthetic organic chemistry. These phenomena are explained in the context of aliphatic and aromatic alcohols.
Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...
