We recommend you store the product at room temperature, with the cap tightly closed. Avoid direct sunlight and heat sources. These measures will help extend the quality of the product.

Vegetable Glycerin is highly stable, and the product will be best up to 3 years after the manufacturing date. See our storage recommendations to maximize quality of the oil.

Pure Glycerin is stable and cannot go easily rancid. The storage conditions are important though. The container must be kept sealed at room temperature because Glycerin can easily absorb water from moisture in the air. If there is more water in the bottle, there is more opportunity for bacteria to proliferate.

Vegetable Glycerin is made by steam hydrolysis of fatty acids derived from plant-based materials at high temperature. The split fatty acids are pre-concentrated through water evaporation to obtain crude glycerin, which then is further refined to achieve high purity.

Yes.

It means we comply with the purity and quality standards set by the United States Pharmacopeia Convention (USP), a nonprofit scientific organization. They develop strict standards that ensure stability, safety, and efficacy of the chemical(s) used in medicines and other articles.

We do not recommend you heat Glycerin unless it's necessary for specific applications. The oxidation or rancidity rate will accelerate due to high temperature.

Although our Vegetable Glycerin is food grade and fit for human consumption, it is intended for cosmetic use on the skin, hair or nails. It does not have nutrition facts on the label.

When Vegetable Glycerin remain open without the cap, oxidation will occur more quickly.

No.
