Hydralay Surfactant
Description
Hydralay Surfactant - Biolipid with a structure similar to the skin's own lipids, for moisturizing and gentle cleansing formulations.
Hydralay Surfactant is primarily used as a lipid layer enhancer for surfactant-based cleansing preparations, contributing to a feeling of gentleness and comfort far beyond that of conventional cleansing formulas. It also enhances the viscosity of surfactant-based formulas.
It is a blend of an alkyl glucoside (Coco-Glucoside) and a fatty acid glycerol ester (Glyceryl Oleate). The latter, glyceryl monooleate, is structurally similar to a lipid naturally present in human skin, which is why the manufacturer describes it as a “biolipid”.
Ingredients (INCI): Coco Glucoside, Glyceryl Oleate, Aqua
Technical Characteristics
- Appearance: Slightly yellowish viscous liquid with a characteristic odor.
- Solubility: Dispersible in the aqueous phase of surfactant-based formulas.
- Quality: 100% plant-derived, renewable raw material, COSMOS-approved by the manufacturer, non-GMO, not tested on animals.
- Recommended dosage: 1-5%
Studies and Scientific Documentation
According to tests conducted by the manufacturer, lipid extraction from the skin showed a reduction in the level of glyceryl monooleate ("biolipid") immediately after washing, followed by a recovery of this level 4 hours after using a product formulated with this ingredient – data interpreted by the manufacturer as evidence of the deposition and persistence of the "biolipid" on the skin. Additionally, at a 5% dosage, the alkyl glucoside content (a surfactant with high dermatological value) contributes approximately 1.7% to the total active washing substance of the formula, allowing for a reduction in the amount of primary or secondary surfactant. These data originate from the manufacturer's internal testing, not from independent clinical studies.
Properties and Benefits
- Acts as a lipid layer enhancer in surfactant-based cleansing products.
- Contributes to strengthening the skin's barrier function.
- Softens and moisturizes skin and hair.
- Increases the viscosity of surfactant-based preparations.
- Improves the gentleness level of hygiene preparations.
- Imparts a soft, smooth feel to skin and hair.
- Compatible with PEG-free (EO-free) and cold-process formulas.
Applications
- Shower gels, bubble baths, liquid soaps, cleansing lotions.
- Baby care hygiene products, facial cleansers, wet wipes.
- Solid and liquid shampoos.
Formulation Guide
- Indicative dosage: 1% for a proven lipid layer enhancement effect in light care; 3% for soft, supple skin with a noticeable effect; 5% for an intensive moisturizing effect.
- Preferably processed at temperatures between 15 and 25°C.
- Used as a lipid layer fortifier in surfactant-based hygiene products, added together with the remaining surfactants in the formula.
- Contributes significantly to the viscosity of the final formula, adjusting other thickening agents accordingly is recommended.
Usage Safety and Storage
- Profile: Safe ingredient with good skin tolerance.
- Precautions: External cosmetic use.
- Storage: In closed original packaging, protected from moisture, at temperatures between 10 and 30°C.
