The present disclosure is directed to novel derivatives of terpenes, particularly ester derivatives of terpene alcohols, and methods of making them, compositions comprising them, and methods for using them.

The present invention relates to a plasticizer composition and a resin composition including the same. The compositions comprise a terephthalate-based material, a dibenzoate-based material, and a citrate. The compositions and methods have a weight ratio of the terephthalate-based material to the benzoate-based material of 99:1 to 1:99. The citrate-based material is included at 1 to 80 parts by weight with respect to 100 parts by weight of the total weight of the terephthalate-based material and the dibenzoate-based material.

A system and method for data privacy in URL based context queries. A reference to a data object is received from a user. At least one entity that controls the data object is identified via the network. At least one permission for the data object is retrieved via the network, wherein the permission is associated with the entity that controls the data object. It is then determined, via the network, if the user is permitted to access to the data object using the permission for the data object and spatial data, temporal data social data and logical data available to the network that relates to the user and to the permission for the data object. If the user is permitted access to the data object, access is granted to the data object, and if the user is nor permitted access to the data object, access is denied to the data object.

Provided is a citrate-based plasticizer and a resin composition including the same. The citrate-based plasticizer includes one or more citrates having alkyl groups with 7 carbon atoms. The citrate-based plasticizer can solve limitations on migration and volatile loss inherent in the conventional plasticizer and limitations on characteristics of processing such as plasticizing efficiency and absorption rate.
