Verzepingsgetallen
Hier vind je de verhoudingen voor de verschillende vetten t.o.v. de NaOH. Met dank aan en met toestemming van Elaine White, auteur van het boek "Soap Recipes".
Het gebruik van de tabel is eenvoudig. Neem de hoeveelheid vet (het gewicht)die je hebt en vermenigvuldig dit met het getal. Het resultaat geeft aan hoeveel NaOH (het gewicht) je moet gebruiken. Gebruik je meerdere vetten tegelijkertijd, tel dan je berekende hoeveelheden NaOH bij elkaar op.
Om te bepalen hoeveel water je nodig hebt (ook weer gewicht), vermenigvuldig het gewicht van de NaOH met 2,8. Hiermee krijg je een oplossing van ongeveer 36%.
Tip: Deze getallen zijn zeer nauwkeurig. Om een voor de huid extra zachte zeep te maken, neem dan 5% meer vetten. Hierdoor droogt de huid minder uit, en loop je minder het risico dat er NaOH achter blijft.
