**Introduction to GLYCERIN BASE** GLYCERIN BASE is a versatile and high-purity glycerin formulation designed for a wide range of applications in cosmetics, pharmaceuticals, and personal care products. Known for its exceptional humectant properties, it effectively attracts and retains moisture, making it ideal for hydrating skin, hair, and sensitive formulations. Its non-irritating, hypoallergenic nature ensures compatibility with all skin types, including dry and sensitive skin. GLYCERIN BASE serves as a key ingredient in creams, lotions, soaps, and medicinal syrups, enhancing texture, stability, and shelf life. With its superior viscosity and solubility, it is a preferred choice for formulators seeking a reliable, multifunctional base for high-quality end products.
Preparation Process: **Preparation Method of Glycerin Base:** 1. **Ingredients:** Gather glycerin (85–90% purity), purified water (10–15%), and optional additives like preservatives (e.g., phenoxyethanol) or humectants (e.g., propylene glycol). 2. **Mixing:** Combine glycerin and purified water in a stainless-steel or glass container at a ratio of 9:1 (glycerin to water). 3. **Heating:** Warm the mixture to 40–50°C while stirring continuously to ensure homogeneity. 4. **Cooling:** Allow the solution to cool to room temperature while stirring to prevent separation. 5. **Adjustment:** Check viscosity and adjust with additional water or glycerin if needed. 6. **Filtration:** Filter the mixture through a 0.45-micron filter to remove impurities. 7. **Storage:** Transfer to airtight, light-resistant containers. Label and store in a cool, dry place.
Usage Scenarios: Glycerin Base is widely used in pharmaceuticals, cosmetics, and food industries due to its humectant, solvent, and emollient properties. In pharmaceuticals, it serves as a vehicle for suppositories, cough syrups, and topical formulations, enhancing drug stability and absorption. In cosmetics, it moisturizes skin and hair, preventing dryness while improving product texture. The food industry employs it as a sweetener, preservative, and thickening agent in confectionery and beverages. Additionally, glycerin base acts as a lubricant in medical devices and industrial applications. Its non-toxic, hypoallergenic nature makes it suitable for sensitive formulations, ensuring safety and efficacy across diverse applications.
