Abstract

This invention relates to plastic additives which are useful as nucleating agents and which are especially useful for improving the optical properties of polymeric materials. More particularly, this invention relates to certain bis-halogen-alkyl-benzylidene alditol acetals and polymer compositions thereof which are useful as materials for food or cosmetic containers and packaging. These bis-halogen-alkylbenzylidene alditol acetals are also useful as gelling agents for organic solvents, particularly those used in the preparation of antiperspirant gel sticks.
