Kester Wax
| Kester Wax Explained |
|
Ester chemistry used in personal care and cosmetics can range from oils to waxy solids depending on their molecular weight. The differences in composition will affect the product form, its properties, and its behavior in finished formulas.
Each of Koster Keunen’s Kester Waxes are created for different performances in finished products.
FORMULATION GUIDELINES
Each Kester Wax follow the same basic guidelines. Melt into oil phase. Best practices for working with wax chemistries is to melt 5-10 degrees over melt point.

Kester Wax K-24
Wax No. 6358B
A non-traditional wax ester, Kester Wax K-24 is a solid at room temperature with performances comparable to a liquid ester in formulations. This product will not structure systems. Kester K-24 is highly compatible in all systems, similar to most cosmetic oils and liquid esters.
Solid to Liquid in a Blink
Kester Wax K-24 has a fast phase change allowing this ester to transition from solid to liquid instantly. The chemistry lends an initial cooling effect in some emulsion formulas, and provides that “instant slip” in formulation provided by the low melt point (25°C).
Applications
Highly versatile ester wax that can be used in all applications including Skin Care, Hair Care, Color Cosmetics, Sunscreens, AP/DEO, Wash-off or Leave-on products. Acceptable for natural, clean beauty and vegan formulas.

Formulation Guidelines
- Easy to use. Combine emulsifier with the oil phase and heat until phase is melted and homogeneous. Add to hot water phase and mix with conventional mixer (propeller or paddle) at high speed until emulsion is formed. Cool with medium speed until pour temp (40°C or lower).
- Lab results show homogenization does not negatively affect the emulsifier and can be used as needed for complex and stabilizers.
- Need to increase the oil to emulsifier ration beyond 3:1? This is attainable by using additional support thickeners and stabilizers.
