Cleaning composition for recycling of plastics

A cleaning mixture, comprising:

• 0.01 wt % to 2.00 wt % based on the total weight of the cleaning mixture, a cleaning composition comprising a glycol ether selected from the group consisting of diethylene glycol mono hexyl ether and tripropylene glycol mono n-butyl ether;
• and a surfactant selected from C12-C15 secondary alcohols having an average of 15 moles of ethylene oxide;
• 0.01 wt % to 3.00 wt % an alkali salt based on the total weight of the cleaning mixture;
• and
• water.

A cleaning method, comprising the steps of:

• adding a polymeric material to a cleaning mixture comprising:
• a cleaning composition at a percent by weight (wt %) of the cleaning mixture ranging from 0.01 wt % to 2.00 wt %;
• and
• an alkali salt in a range of 0.01 wt % to 3.00 wt %;
• wherein the cleaning composition comprises a surfactant having a cloud point of 60° C. or greater at a percent by weight (wt %) of the cleaning composition ranging from 25 wt % to 75 wt %;
• and a glycol ether having a hydrophilic-lipophilic balance (HLB) from 6 to 10 and ranging from 25 wt % to 75 wt %;
• and
• washing the polymeric material in the cleaning mixture at a temperature from 60° C. to 90° C.
