Abstract

Ulja i masti predstavljaju najvažnije sirovine u proizvodnji sapuna. Budući da sastav masnih kiselina uvelike utječe na kvalitetu i na karakteristike dobivenog sapuna, neće sva ulja, odnosno masti, odgovarati kao dobar izbor sirovine. Sapuni spadaju u skupinu površinski aktivnih tvari, te kao takvi pokazuju sposobnost pjenjenja, emulgiranja, dispergiranja, močenja i slično. Sapuni su soli viših masnih kiselina, koji se dobivaju postupkom saponifikacije masti natrijevim ili kalijevim hidroksidom, a kao produkt uz sapun nastaje i glicerol koji se dalje iskorištava u različitim industrijama, ovisno o namjeni. Obzirom na teksturu razlikujemo nekoliko vrsta sapuna: toaletni, tvrdi, sapuni ili kreme za brijanje, meki i tekući sapuni. U proizvodnji sapuna često se koriste biljna ulja kokosa, uljane palme, masline, ricinusa koja su opisana u ovom završnom radu.

Abstract (english)

Fats and oils are the most important raw materials in soap production. Since the composition of fatty acids greatly affects the quality and characteristics of the finished product, not all oils or fats will be suitable as raw materials. Soaps belong to the group of surface-active agents, and as such show, the ability to foam, emulsify, disperse and wet. Soaps are salts of fatty acids and are formed through the process of saponification of fats or oils in an alkaline solution of sodium or potassium hydroxide. This reaction produces glycerol as a by-product, which is further used in various industries, depending on the purpose. Depending on the texture, we distinguish several types of soaps: toilet, hard, soaps or shaving creams, soft and liquid soaps. Plant based oils that are often used in soap production are coconut oil, palm oil, olive oil, castor oil, some of which are presented in this thesis.
