What is Glycerin?
Glycerin, also known as glycerol, is a naturally occurring compound found in both plant and animal fats. It is a byproduct of the soap-making process and can be derived from vegetable oils, such as palm or soy, or from petroleum sources. Its sweet taste and ability to attract moisture make glycerin a popular ingredient in cosmetics, personal care products, and even food.
In skincare, glycerin is highly valued for its humectant properties, meaning it attracts moisture from the environment and helps retain it in the skin. This makes it an excellent addition to moisturizers and serums, especially for those with dry or dehydrated skin.
The Benefits of Glycerin in Skincare
- Hydration: Glycerin draws moisture into the skin, aiding in hydration and keeping the skin plump and supple.
- Soothing: Its gentle nature makes glycerin suitable for sensitive skin, helping to alleviate dryness and irritation.
- Enhancing Formulations: Glycerin acts as a binder in formulations, ensuring a smooth and consistent texture in products.
At Moon and Skin, we incorporate glycerin in our formulations to ensure that our products not only hydrate but also support your skin’s overall health and appearance. For instance, our Hyaluronic Brightening Moisturizer is designed to deeply hydrate and brighten your skin, thanks to the inclusion of glycerin along with other powerful ingredients.
How Long Does Glycerin Last Once Opened?
When it comes to glycerin's shelf life, the good news is that it is notably stable. Glycerin does not have a strict expiration date, especially when stored properly. Once opened, glycerin can last for several years if kept in a cool, dry place away from direct sunlight.
Factors Affecting Shelf Life
- Storage Conditions: The longevity of glycerin is heavily influenced by how it is stored. Keeping it away from heat, moisture, and light is crucial for maintaining its quality. Ideally, glycerin should be stored in a dark, cool cabinet or pantry.
- Container Integrity: Ensure that the container is tightly sealed after each use. Exposure to air can lead to contamination and degradation over time.
- Purity: The purity of glycerin affects its shelf life. Pure vegetable glycerin, which is often used in cosmetics, has a longer shelf life compared to glycerin that contains additives or impurities.
- Signs of Spoilage: Although glycerin is stable, it’s wise to check for any changes in color, odor, or texture before use. If you notice any significant changes, it’s best to err on the side of caution and replace the product.
Summary of Glycerin Shelf Life
