Organic Vegetable Glycerin

Also known as: Glycerol, Vegetable Glycerin, Glycerin

Overview

Vegetable glycerin, also known as glycerol, is a clear, odorless liquid derived from plant oils like soy, palm, and coconut. It is widely used in the food, cosmetic, and pharmaceutical industries due to its moisturizing and humectant properties. As a humectant, it attracts moisture from the air into the skin, making it a popular ingredient in skincare products. It's also used in e-cigarettes and as a sweetener. While generally considered safe, research on vegetable glycerin is still evolving, and more studies are needed to fully understand its effects on human health. Available evidence suggests potential benefits in hydration and skin health. It is available in various forms, including liquid and as an ingredient in creams and lotions.

Benefits

Vegetable glycerin primarily enhances hydration by increasing fluid retention, which can be particularly beneficial for athletes or individuals experiencing dehydration. Studies indicate that glycerin can improve skin hydration, reduce irritation, and promote wound healing due to its humectant properties. Some evidence suggests it may also help relieve constipation and improve athletic performance by maintaining hydration levels during intense exercise. One study demonstrated a 50% increase in fluid retention compared to water alone when using glycerin. The benefits for hydration are typically observed shortly after ingestion or topical application, making it a quick and effective option for improving moisture levels.

How it works

Glycerin functions primarily as a humectant, drawing moisture from the air into the skin and other tissues. This mechanism enhances skin hydration and can aid in wound healing by maintaining a moist environment. It interacts mainly with the skin and gastrointestinal systems. While specific molecular targets are not well-defined, its action as a humectant is well-established. Glycerin is readily absorbed both orally and topically, allowing for versatile application in various products. Its ability to attract and retain moisture contributes to its widespread use in cosmetics and therapeutic applications.

Side effects

Vegetable glycerin is generally considered safe for use in cosmetics and as a food additive. However, some individuals may experience gastrointestinal upset, such as bloating or diarrhea, particularly at high doses. Allergic reactions are rare but possible. No significant drug interactions have been reported. Caution is advised for individuals with severe gastrointestinal issues. Pregnant or breastfeeding women should consult healthcare providers before using glycerin supplements. A study in mice indicated potential respiratory risks when inhaled, suggesting caution with vaporized forms. Overall, vegetable glycerin has a good safety profile when used appropriately, but moderation and awareness of potential side effects are important.

Dosage

For hydration purposes, a dose of approximately 1.1 g/kg body weight (or 0.5 g/lb) is often recommended. In topical applications, glycerin is typically used in concentrations up to 30%. Oral doses vary depending on the intended use. While there is no established maximum safe dose, high doses may cause gastrointestinal discomfort. For hydration benefits, it is best taken before exercise. Vegetable glycerin is available in liquid form for both oral and topical use. Absorption is generally good but can vary based on individual factors. No specific cofactors are required for its activity.
