This article focuses on the synthesis of hydroxyethyl potato starch (HEPS) for liquid hand soap by evaluating waste potato starch (WPS), a byproduct in potato chips production. It is a cheap, biodegradable, non-toxic and renewable natural polymer, available in great quantities on a global level. In a factory producing potato chips, WPS, which remained in the aqueous medium during peeling, slicing, and washing the potatoes, was purified at the desired temperature with H2O2 and NaOH. HEPSs with the molar substitution (MS) in the range from 0.298 to 0.670, were synthesized under microwave irradia ...More
Chitin, the main component of shellfish such as crab and shrimp, is one of the most used biopolymers after cellulose. Today, although recycling of waste is becoming increasingly important, large quantities of seafood shells such as crab and shrimp are being destroyed around the world without much evaluation. Chitosan, which is non-toxic, biodegradable-biocompatible and has many application advantages compared to chitin, is used in many sectors, especially cosmetics, pharmaceuticals and agriculture, as it shows superior properties compared to other biopolymers in terms of chemical and physical ...More
