Investigation of natural homemade soaps : bachelor thesis

Sapuni su organski kemijski spojevi dobiveni procesom saponifikacije tj. bazične hidrolize masnih kiselina. Od davnina koriste se kao sredstva za čišćenje i pri svakodnevnom održavanju higijene, nezamjenjivi su i u raznim industrijama poput tekstilne. Povećanjem svijesti ljudi o proizvodima koje koriste i o njihovom utjecaju na okoliš sve veća je potražnja za sapunima kućne izrade koji ne sadrže sintetske dodatke. Pripravljena su i analizirana tri sapuna različitih receptura čije su sastavne komponente ista ulja i to kokosovo, maslinovo, palmino i ricinusovo ulje. Sapuni su pripravljeni postupkom na hladno i bojani su prirodnim bojilima, a mirisna komponenta u njima su cvjetovi smilja. Kao bojila korišteni su sok od mrkve, crvena paprika i kurkuma. Dobiveni sapuni su analizirani i uspoređeni s komercijalnim sapunom kako bi se odredila najbolja receptura.Soaps are organic chemical compounds obtained by the process of saponification or alkaline fatty acid hydrolysis. Since ancient times they have been used as cleaning agents and in daily maintenance of personal hygiene, they are irreplaceable in various industries such as textile. With the increase of people's awareness of the products they use and their impact on the environment, there is an increasing demand for homemade soaps that do not contain synthetic additives. Three soaps of different formulations were prepared and analyzed. Each are made of same components and those components are coconut oil, olive oil, palm oil and castor oil. The soaps were prepared using the cold process. The fragrant components are flower buds of immortelle. Carrot juice, red pepper and turmeric were used as colourants. Three different soaps were analyzed and compared with commercial soap to determine the best recipe
