TIME SAVING GUIDE TO SURFACTANT SELECTION
THE HLB SYSTEMTHE HLB SYSTEMA time SAVING GUIDETO SURFACTANT SELECTIONP resentation to the Midwest chapter of the Society of Cosmetic ChemistsMarch 9th2004 WHAT DO WE MEAN BYSURFACTANTSELECTION First -selecting between the available chemical types anionic, Negative charge cationic, Positive charge amphoteric Charge depends on pH Nonionic No chargeWHAT DO WE MEAN BYSURFACTANTSELECTION Second once having selected the chemical family You must select a SURFACTANT or SURFACTANT pair with the correct solubility for your unique applicationWHAT DO WE MEAN BYSURFACTANTSELECTION How does SURFACTANT solubility affect performance ? For example ( very general rules ) You need high water solubility for cleansing and detergency You need medium solubility for spreading and dispersion You need low solubility for invert emulsions and coupling immiscible oils You need a blend of solubilities for O/W emulsionsWHAT DO WE MEAN BYSURFACTANTSELECTION Is there a way to predict SURFACTANT solubility by merely looking at its chemistry?
