Solubility Guide

How the 3,232 materials in this catalogue behave in water, oil and the carrier systems in between — and which phase each one belongs in.

By solubility class

WATER SOLUBLE

Dissolves into the water phase. Add with stirring; most are stable at room temperature but check the pH window on the entry. Water-Soluble Actives 1099

OIL SOLUBLE

Goes into the oil phase. Several need gentle warming to dissolve fully before the emulsion is formed. Oil-Soluble Actives 885

GRADE DEPENDENT

A large part of the botanical range is supplied in more than one carrier system — powder, glycolic, glycerine or oil — and the solubility follows the carrier, not the plant. The entry for each material says so explicitly; confirm the carrier on the supplier data sheet before you design the phase it goes into.

Where it is recorded

Every one of the 3,232 entries in the Ingredient Dictionary carries a SOLUBILITY line, the phase to add the material in, and a pH window.

Everything on this page is derived from the MakeYourSkin catalogue and from supplier literature. It is a starting point for your own development work, not a specification. Confirm every figure against the technical data sheet and Certificate of Analysis for the grade and batch you buy.
