The present invention relates to compositions for personal care products which have a composition containing hydroxyalkylurea in combination with at least one or more other moisturizing agents in a ratio, which synergistically increases moisturization efficacy. Hydroxyalkylurea is derived from urea, wherein the 4 hydrogen radicals on the nitrogen atoms of a urea molecule may be replaced by a C1-4 alkyl or a lower C2-6 hydroxyalkyl group, which may contain from 1 to 5 hydroxyl or hydroxyalkyl groups, providing at least one of the radicals on one of the nitrogen atom of a urea molecule is a hydroxyalkyl or oligohydroxyalkyl group. Preference is given to N-2-hydroxyethylurea with a hydroxyethyl group on one of the nitrogen atom of a urea molecule. Hydroxyalkylurea can also be used alone as a moisturizer for skin and hair. This topic will be the subject of future publications.
