Oils and fats<\/h2>\n

Oil encyclopedia for soap making<\/h3>\n

You need to know the SAP numbers and the properties of the oils for a proper recipe.

Fragrances<\/h2>\n

Essential oils in soap: selection, usage rates, stability<\/h3>\n

Essential oils add fragrance and can speed up the trace. IFRA limits for the most common EOs, table of trace accelerators (clove, cinnamon, vanillin), citrus EOs and their volatility, phototoxic EOs, combining EOs in compositions - all in EO guides<\/a>. Where to buy in the Czech Republic.<\/p>\n

Fragrance oils in soap: soap safe, flash point, vanillin<\/h3>\n

The difference EO vs. FO is important for the choice of fragrance. Learn soap safe test<\/a>, flashpoint, trace acceleration in FO, vanillin browning, documentation for sale (SDS, IFRA certificate, INCI allergens). Soap testing protocol.<\/p>\n

Additives and supplements<\/h2>\n

Soap additives: honey, clays, silk, oatmeal<\/h3>\n

Ingredients transform soap - adding texture, scent or benefits. Encyclopedia Ingredients<\/a> with function, dosage and addition technique: honey, oatmeal (colloidal vs. coarse), kaolin, green clay, bentonite, rhassoul, silk fibers, panthenol, vitamin E, ROE, sodium lactate.<\/p>\n
