Preservative actives for personal care products require high standards of safety and compatibility. Just a few of the numerous well-known and permitted preservative actives are used in the majority of cosmetic products throughout the world.

Today, however, more and more of the well-known and accepted preservative actives are being regarded increasingly critically, both by specialists and by public. Among those are the parabens, used safely and effectively for many years in cosmetics, pharmaceuticals and even food. To a certain extend the cosmetic industry is looking to replace parabens in their products by less “critical” actives.

Organic acids could be an ideal replacement. The use of organic acids is limited to a pH below 6, while numerous cosmetic products are formulated in pH ranges between 6 – 7.  With Euxyl® K 500 Schülke & Mayr has launched an organic acid based product, which boosts the efficacy of organic acids up to pH 7.

Euxyl® K 500 is an solvent-free aqueous combination of diazolidinyl urea, sodium benzoate and potassium sorbate.
