Lauryl Glucoside
Lauryl Glucoside is a non-ionic surfactant and alkyl polyglucoside (APG) derived from natural renewable sources like coconut or palm oil and glucose from corn or starch, commonly used as a mild cleansing agent, emulsifier, and foaming enhancer in cosmetic and skincare formulations. It is valued for its gentle, biodegradable nature, low irritation potential, and ability to create stable foams while effectively removing dirt, oil, and impurities without stripping the skin’s natural moisture barrier, making it a popular choice in eco-friendly and sensitive-skin products.
What is it Made of?
Lauryl Glucoside is synthesized through a green chemistry process involving the condensation of lauryl alcohol with glucose, resulting in a viscous, pale yellow aqueous solution typically containing 50-53% active ingredient; it is not a blend but a single compound that may include varying degrees of glucose polymerization for enhanced performance.

Overall Formulation: Lauryl Glucoside is generally supplied as a 50-53% active aqueous solution (e.g., as APG 1214 or Plantacare 1200 UP), with the remainder being water and minor impurities like free fatty alcohols (≤0.8%), free fatty acids (≤1%), and ash (≤2%); it forms a solid at room temperature but is soluble in both water and organic solvents for easy incorporation into formulations.
Active Lauryl Glucoside:
- Chemical Structure: An anomerically-alkyl-substituted D-glycopyranoside with the molecular formula C18H36O6 for the mono-glucoside form, featuring a C12 lauryl chain (dodecyl) attached to a glucose unit; it can include polyglucoside variants with a degree of polymerization (n=1-3 or higher), such as lauryl maltopyranoside, and has properties like a molecular weight of 343-420 Da, boiling point of 499.1°C, density of 1.12 g/cm³, and log P of 2.925.
- Derivation Process: Produced via acid-catalyzed alcoholysis (condensation) of lauryl alcohol—sourced from vegetable oils like coconut or palm through hydrolysis, distillation, and hydrogenation of fatty acids—with D-glucopyranose derived from starch hydrolysis of corn, potato, or wheat; this renewable, eco-friendly process avoids harsh chemicals and yields biodegradable APGs.
- Role in Formulations: Serves as the primary surfactant for gentle cleansing, foaming, and emulsification, breaking down into naturally occurring glucose and fatty alcohol via skin enzymes, while enhancing product stability and viscosity without causing dryness.
Best Skin Type for Using It:
Lauryl Glucoside is best suited for sensitive, dry, or atopic skin types in skincare due to its mild, non-drying cleansing properties:
-
- Sensitive/Atopic Skin: Extremely gentle with low irritation potential, tested safe on atopic patients and suitable for baby products.
- Dry/Dehydrated Skin: Cleanses without stripping natural oils, supporting moisture retention.
- Normal Skin: Provides balanced cleansing and foaming without disrupting the skin barrier.
- All Skin Types: Broadly compatible, including mucous membrane exposure, when formulated to be non-irritating.
-
Avoid:
Individuals with known sensitization to alkyl glucosides, though rare, as it may cause mild allergic reactions in patch tests.
Benefits of Lauryl Glucoside
Lauryl Glucoside offers gentle cleansing and emulsifying benefits by reducing surface tension to remove impurities while maintaining skin hydration:
-
- Mild Cleansing: Effectively lifts dirt, oil, and makeup without drying or irritating the skin.
- Foaming Enhancement: Creates stable, luxurious lather when combined with other surfactants.
- Emulsification and Stabilization: Blends oil and water phases for smooth, consistent textures in creams and lotions.
- Moisture Retention: Supports the skin’s natural barrier by metabolizing into hydrating glucose and fatty alcohols.
- Eco-Friendly Support: Biodegradable and derived from renewables, promoting sustainable skincare formulations.
Pros and Cons of Lauryl Glucoside
Pros:
-
- Naturally derived from renewable plant sources, making it biodegradable, eco-friendly, and aligned with clean beauty standards.
- Extremely mild with low irritation and sensitization potential (EWG score of 1), ideal for sensitive skin and baby products.
- Versatile surfactant that enhances foaming, cleansing, and emulsification without drying the skin or disrupting the microbiome.
- Safe across a wide range of concentrations (up to 10% in rinse-off products) with no genotoxic, reproductive, or carcinogenic concerns.
Cons:
-
- May cause mild dermal or ocular irritation at high concentrations if not properly formulated.
- Potential for rare allergic contact dermatitis in sensitized individuals, as seen in case reports with related glucosides.
- Can enhance skin penetration of other ingredients, requiring caution in formulations with actives.
- Less effective as a standalone thickener compared to harsher surfactants, often needing combination with others for optimal performance.
Lauryl Glucoside is a mild, plant-derived non-ionic surfactant widely used in skincare for its gentle cleansing and emulsifying properties, derived from lauryl alcohol and glucose through an eco-friendly condensation process. It is particularly beneficial for sensitive and dry skin types, offering hydration support and low irritation while being biodegradable and safe at typical concentrations. Despite rare sensitization risks, its versatility makes it a staple in rinse-off products like cleansers and body washes.

Always consult a qualified dermatologist or healthcare provider before using products containing Lauryl Glucoside, especially if you have sensitive, oily, acne-prone, or compromised skin (e.g., eczema, rosacea), are pregnant, or have pre-existing medical conditions. Individual results may vary, and while Lauryl Glucoside is generally well-tolerated, some users may experience allergic reactions, irritation, or stinging, particularly with high concentrations, very sensitive skin, or improper formulation. Patch testing is strongly recommended before use, especially for sensitive or allergy-prone skin or new products. Avoid applying to broken or inflamed skin, and use high-quality, sustainably sourced Lauryl Glucoside to minimize environmental impacts and ensure purity. Store products in a cool, dark place to prevent degradation. The author is not liable for any adverse effects resulting from the use of Lauryl Glucoside based on this information. Claims are based on peer-reviewed scientific research, but efficacy and safety depend on formulation, concentration, and individual skin type.
