What is Lauryl Glucoside?
Lauryl Glucoside (INCI: Lauryl Glucoside; trade name: APG 600; also called Lauryl Polyglucoside) is a non-ionic surfactant in the alkyl polyglucoside (APG) family, synthesized from lauryl alcohol (C12 fatty alcohol derived from coconut oil) and glucose. It is closely related to decyl glucoside (APG 100, C10 chain), differing only in its longer alkyl chain length.
Like decyl glucoside, lauryl glucoside is derived from renewable natural sources (coconut and plant sugars) and is marketed as a mild, biodegradable, and environmentally friendly surfactant. It is a component of many "natural," "organic," and "gentle" personal care products, particularly shampoos, baby washes, and body washes.
The ACDS has documented lauryl glucoside as a contact allergen, consistent with the broader pattern of APG family sensitization described for decyl glucoside.
Why does Lauryl Glucoside cause reactions?
The sensitization mechanism for lauryl glucoside parallels that of decyl glucoside — reactive hapten formation under skin conditions. Cross-reactivity between lauryl glucoside and decyl glucoside is expected given their structural similarity (same glucose head group, slightly different chain length). Patients sensitized to one APG member should be considered at risk for reactions to other APGs.
The clinical presentation is typically contact dermatitis correlating with shampoo, body wash, or baby product use. Scalp dermatitis, facial dermatitis from rinse water, and hand dermatitis from hand wash are the most common manifestations.
Where is Lauryl Glucoside found in products?
- Natural and organic shampoos: Extremely common in the natural hair care segment
- Baby shampoos and washes: Marketed for gentle cleansing
- Body wash: Natural body care formulations
- Face cleansers: Natural cleansers using APG surfactants
How to spot Lauryl Glucoside on labels
- Lauryl Glucoside — INCI name
- APG 600 — industry name (not on product labels)
Frequently appears alongside decyl glucoside or coco glucoside in ingredient lists.
In Indian products 🇮🇳
Lauryl glucoside is widely used in Indian natural and organic personal care products. Many of the same Indian brands that use decyl glucoside also use lauryl glucoside — Mamaearth, WOW, The Moms Co., Plum, and Biotique (selected ranges). Imported natural brands available through Nykaa and Amazon India also commonly contain it.
For Indian consumers investigating natural shampoo or baby product reactions, both decyl glucoside and lauryl glucoside should be checked in the ingredient list, as they frequently appear together.
Safer alternatives
- Sodium cocoyl isethionate: Different chemical family; generally gentle
- Sodium lauroyl sarcosinate: Amino acid-derived; different chemistry from APGs
- Simple soap bars: For hand washing, traditional soap avoids both APGs and sulfates
- Patch-test new products: Any switch to a new "natural" surfactant system deserves a forearm patch test before full use, particularly if APG allergy has been demonstrated
