Introducing New Kester Wax K42 and EcoWax JP!

Two new launches. Both medium-melting-point waxes. Both are designed to change the way you think about texture, structure, and feel.

At in-cosmetics global this year, Koster Keunen added two new waxes to their portfolio, each bringing distinct benefits to cosmetic formulations.

Their Kester Wax K42 was designed to bridge the melting point gap between K24 and K62 offering formulators a precise intermediate thermal option. Their Eco Wax JP offers a thermally superior, more consistent and sustainable alternative to Japan Wax.

Both waxes can be used for a variety of personal care applications including: skin, hair, body, lip, sun, and colour cosmetics.
