Solidifying Glycerin

Glycerin (USP/Food Grade) is naturally a liquid at room temperature and only solidifies at temperatures below 18°C (64°F), which is not a practical method for most applications.

Mixing Glycerin with Sodium Hydroxide is not a method to solidify it and can be dangerous due to the chemical reaction that may occur. It is strongly advised against.

To create a solid or gel-like texture using Glycerin in formulations, you typically need to use gelling agents or thickeners. One product designed for this purpose is Glycerin Gel (Glyceryl Polyacrylate). This product is a gel base that can be mixed with water to create a gel texture, leveraging the moisturizing properties of Glycerin.

Using Glycerin Gel (Glyceryl Polyacrylate):

• It can be mixed with water at a ratio of approximately 1 part Glycerin Gel to 20 parts water to achieve a gel texture.
• Recommended usage rate is typically 1-20% in your formulation, depending on the desired thickness.

Therefore, while pure Glycerin doesn't solidify easily with simple additives like Sodium Hydroxide, you can achieve a solid or gel-like consistency in a formulation by using appropriate gelling agents or pre-made bases like Glycerin Gel.
