  • Publication number: 20200377716
    Abstract: The hot melt compositions of this invention include from 15% by weight to 60% by weight of a styrene block copolymer, from 15% to 75% by weight of a wax having a Congealing Point (ASTM D938) of from 45° C. to 90° C. and optionally a propylene based polymer. The hot melt composition can be free of both tackifying agent and plasticizer and is useful in a variety of hygiene applications.
