Abstract:

A green prospective based on the reuse of waste materials such as beef tallow and waste cooking vegetable oils to manufacture soap is presented. Beef tallow and waste cooking oils that is discarded as waste from households and restaurants after frying is reviewed for the production of toilet (bath) soap. The discarded oil is purified with a brine solution and bleached with Hydrogen Peroxide (H2O2.) Purified waste cooking oils and beef tallow is mixed with coconut oil commonly used oil in toilet soap manufacturing. The oils are normally mixed at different ratios for the preparation of toilet soap. The triglycerides in the vegetable oils and beef tallow are saponified with Sodium Hydroxide (NaOH) by hydrolysis. Cold process soap shows significant improvements in physical properties at different triglycerides ratios and storage time at room temperature. It could be recommended that discarded waste cooking vegetable oils can be used after purification and bleaching together with beef tallow that may be regarded as waste to produce toilet (bath) soaps.
