Formulating personal care products demands attention to the finest details, and the end results must match the required esthetic while being stable and pleasurable to use. Choosing Kester Wax K-48 for your system offers superior opacity for all your bright white formulation needs.

Reliable Results – Flexible Formulation

Whether you are working toward a traditional formula, a natural or vegan product, Kester Wax K-48 provides a rich white color base for the final product. A plant-derived, long-chain ester, Kester Wax K-48 has proven its mettle when compared head-to-head to cetyl alcohol (a commonly used opacifier that adds thickness-even if not required) in both a mass-market hair conditioner formula and in a high-end, all-natural face cleanser formulation.

In both cases, the Kester Wax K-48 provided a truer white color without affecting the viscosity.  An added bonus, it provides better slip and bounce over the same formula with cetyl alcohol.

Opacity in Anhydrous or Emulsion Systems

Looking for an opacifier that will do double-duty in the lab? This one product can go from anhydrous, to emulsions to body washes. In anhydrous systems, Kester Wax K-48 is highly compatible with standard carrier oils, and gives a rich, solid look to both pigmented and unpigmented products.  In lotions, creams, and surfactant emulsions, it acts as an opacifier and supports consistency. In all cases, the opaque emollient creates luxurious texture while supporting the system. Kester Wax K-48 is a multi-tasking ester that manages to provide consistency and bright white formulas without affecting the overall thickness or texture of the system as shown in these example formulas.
