Microcrystalline Wax Yellow (Serwax) – Cosmetic Grade Slab

Microcrystalline Wax Yellow (Serwax) is the kind of ingredient that quietly holds everything together. Where paraffin wax is coarse and brittle, microcrystalline wax is fine, dense, and remarkably flexible — its tightly packed crystal structure giving it a binding strength and elasticity that makes it indispensable in both cosmetic and industrial formulations.

In the cosmetic lab, it’s the ingredient that gives a lipstick its smooth glide without cracking, a balm its satisfying body, and a cream its structural integrity at higher temperatures. In industrial applications, it brings the same reliability to polishes, coatings, and adhesive blends. Wherever you need a wax that performs under pressure, Micro Wax Yellow delivers.

Formulation Tips

Always melt fully before incorporating into your formulation. Combine with beeswax or paraffin to create custom wax blends with tailored hardness and flexibility profiles. Ideal for improving structural stability in stick and slab formats. Adjust the ratio of microcrystalline to other waxes to fine-tune the final texture and performance of your product.
