In various exemplary embodiments, a system and an associated method to retrieve information related to marketplace items within an electronic environment are disclosed. A network architecture comprises a listing module to store the information related to the marketplace items. The related information includes one or more user-created items such as an image of a model with one or more tagged items worn by the model. Each of the one or more tagged items has associated descriptive metadata. A communications module is arranged to receive a query including search terms related to social fashion items from an end-user. A query engine is coupled to the communications module to match the search terms contained within the query to the associated descriptive metadata of the tagged items in the listing module. A processing module then displays to the end-user the model and the one or more tagged items.

The present disclosure provides a polyetheramine alkoxylate compound containing aromatic groups in the hydrophobe allowing the compound to exhibit unique functionality, high performance and low cost, but without the toxicity and/or skin and eye irritation problems associated with conventional polyetheramine compounds.
