How to Use Microcrystalline Wax in Formulations

Regarding your question about using Microcrystalline Wax, your understanding of melting it in oil with heat before adding it to your formula is correct.

Mixing Method

Microcrystalline Wax is typically added to the oil phase of a formulation and heated until it is fully melted. This allows it to properly incorporate into the oil and contribute to the desired texture and viscosity upon cooling.

Storage vs. Usage

The instruction on the packaging to avoid heat and sunlight refers to long-term storage of the raw ingredient. Prolonged exposure to heat and light during storage can potentially affect the quality or shelf life of the wax before it is used. However, applying heat temporarily during the formulation process to melt and mix the wax is the standard and necessary method for incorporating it into your product.

Using Microcrystalline Wax for Solid Deodorant Sticks

Microcrystalline Wax is an excellent choice for creating solid stick formulations like deodorant. It has a high oil absorption capacity and helps to structure the oil phase, providing hardness and stability to the stick. To make a solid deodorant stick, you would typically:

1. Combine Microcrystalline Wax with the oil phase ingredients (like carrier oils or silicones) in a heat-resistant container.
2. Heat the mixture gently, stirring until the wax is completely melted and the mixture is clear.
3. Add any heat-sensitive ingredients (like fragrances or active deodorant ingredients) once the mixture has cooled slightly but is still liquid.
4. Pour the liquid mixture into your deodorant stick molds or containers.
5. Allow the mixture to cool and solidify completely at room temperature or in the refrigerator to form the solid stick.

The amount of Microcrystalline Wax used will depend on the desired hardness of the final stick, typically ranging from 1% to 20% or more in some formulations.
