Combinations of well-known paraben-Phenoxyethanol blends with Caprylyl Glycol have proven to be very effective as broad-spectrum preservative system. This strength is used in the Dekaben POEM. The Dekaben POEM is a combination of Phenoxyethanol, which safety has been reconfirmed in 2016, the two shortest parabens Methylparaben and Ethylparaben, and the moisturiser Caprylyl Glycol. Dekaben POEM is meant for cosmetic products, and is halal certified.
