Lime Peel Can be Made into Environmentally Friendly Dishwashing Soap

 - Lemon oil as additional fragrFrance

First, weigh all the ingredients needed according to the basic formulation of 500 g of soap.  150 grams of lime peel infused oil is heated in a slow cooker at 75 C. The function of this infused oil is as a surfactant and emulsifier.  Next, add 103.5 g of 30% KOH solution little by little and stir until it forms a soap paste.  The function of the 30% KOH solution is as an alkali in the saponification process.  This soap paste cooking stage is carried out for 2 hours.  Color changes and clarity tests from the soap paste results were also observed.  Then the dilution process (dilution of the soap paste) was carried out by adding 279.5 g of distilled water, 20.5 g of glycerin and 45 g of propylene glycol and heating at 750C for 3 hours.  The function of distilled water is as a solvent, while glycerin and propyl glycol both function as moisturizers (humectants).  Next, cool down and reduce the temperature to 400C and finally 0.2 grams of lemon oil and mica coloring each are mixed into the soap mixture and stirred for 30 minutes.  The resulting liquid soap can be packaged directly into bottles and ready to use.

Conclusion

Lime peel-based dishwashing soap showed satisfactory results in tests for cleaning grease and bacteria.  The implication is that using this soap can support sustainable practices in daily life, while keeping the kitchen clean.  Utilizing lime peels in making dishwashing soap is an innovative solution that can reduce the negative impact of conventional products on the environment,
