GLYCERIN VEGETAL USP

USP Vegetable Glycerin in Bulk for Cosmetics

USP Vegetable Glycerin is one of the most versatile raw materials in cosmetic formulation, found in creams, gels, soaps and personal care products. This guide covers what it is, how it is produced, and its main applications in professional cosmetics, aimed at labs, artisan soap makers and formulators sourcing raw material in bulk.

What is USP Vegetable Glycerin?

USP Vegetable Glycerin (United States Pharmacopeia grade) is a clear, colorless and odorless liquid obtained through hydrolysis of 100% pure vegetable oils, free from palm oil. Glycerol is concentrated through physical settling of sweet water and further purified by vacuum distillation, ensuring a purity grade suitable for cosmetic and pharmaceutical formulation.

Its most valued property is its humectant capacity: it draws moisture from the surrounding environment and helps transfer it to the skin. This makes it a reference moisturizing agent, compatible with most aqueous and anhydrous bases used in formulation.

Main Cosmetic Uses of USP Vegetable Glycerin

Moisturizer in creams and lotions. It is added to the aqueous phase of emulsions to improve water retention in the skin, delivering an immediate and lasting soft feel without a greasy residue.

Handmade soap formulation. It is a key ingredient in cold-process soap making and in producing transparent glycerin soap bars, giving clarity, a smooth touch and emollient properties to the finished product.

Carrier and solvent in formulas. It works as a solvent for plant extracts, water-soluble actives and preservatives, allowing even dispersion within the system and improving overall formula stability.

Viscosity and texture adjustment. In gels, toothpaste and oral care products, it adds body and a silky texture while contributing to shelf stability. Request a quote or technical sample from Royal Bio to evaluate this raw material for your formulation.
