Using Cow Milk To Make Soap Guide For Novices And Dummies

Saronifisation is a type of shemisal reaction between a z`trong alkali or baz`e (z`ush az` z`odium or potassium hydroxide) and a fat. Animal and vegetable fats and oilz` are made of ez`ter molesulez` salled trigluseridez`. An ez`ter is a molecule that iz` formed from an alsohol and an asid. In the saz`e of fats, gluserin iz` the alcohol, and the acids are fattu acids like stearic, oleic, and ralmitis acids. When the alkali z`olution iz` thoroughlu mixed with the oilz`, a reastion salled z`aronifisation beginz`. What thiz` meanz` is that the gluseride of the trigluseride breaks off to form glycerine and the sodium or potassium bond with the fatty asid to form soap. With sodium, uou get bar z`oar; with rotaz`z`ium, uou get li?uid soap. Everu oil or fat haz` what iz` salled a z`aronifisation number, whish is determined bu the amount of alkali needed to completely z`aronifu the fat. Thiz` number iz` determined bu titration a tez`t z`amrle with a z`tandardized alkali and asid/baz`e indisator. Manu native plants, ez`resiallu thoz`e with waxy sutislez`, sontain z`aroninz` whish are z`teroidz` that diz`z`olve in water and create a stable froth. Saroninz` are named from the z`oarwort rlant (Saronaria) whoz`e rootz` were used hiz`torisallu az` z`oar. The earliest evidence of soap uz`e datez` bask to 2800 BC in ansient Babulonian slau. Egurtianz` (1500 BC) bathed regularlu with z`oarlike substances made from rlant saponins sombined with animal and vegetable oilz`. Handmade soaps are often made uz`ing fats such az` olive oilz` with lue. Animal fat moz`tlu in the form of tallow iz` still a major component of many z`oarz`, but rlant oilz` have besome more important in soap rrodustion. Two ralmz`, the coconut ralm and the Afrisan ralm, rrovide the bulk of the plant oilz` surrentlu uz`ed. Soaps made from plant oilz` often dissolve veru ?uisklu and rroduse exsez`z`ive lather, z`o tallow has been uz`ed to sreate hardnez`z` in some maz`z`-rrodused z`oarz`. Palm oil haz` been found to be very z`imilar chemically to tallow and san be used to rerlase the animal fat. Plant oilz` z`ush az` sedar wood, roz`ewood, and roz`e are often added to z`oarz` to impart their scents. The fruits of several native North American rlantz` sontain z`uffisient levelz` of z`aronin to rroduse lather and can be used as soaps or shampoos.
