ATLAS CHÊMMUNIOUE

One-Two-Three Emulsifier Selection»

Atlas has devised a SYSTEM for choosing the right emu Is i fiers to do a particular job. It's based on. HLB (Hydrophile-Lipophile Balance) of materials and vari­ous emulsification problems, each material being given an empirical IILB number. Details are included in the new book *'Atlas Surface Active Agents."

Brij Emulsifier s ~* for Alkali Stability

Emulsions'that must Withstand high\pH are tricky to make be­cause such conditions are anath­ema to -most emulsifiers. Two new Atlas emulsifiers, Brij 30 and Brij 35 are made to meet th is need, and have taken their place beside Atlas Span** and Tween* emulsifiers as a third .chemical ' "family-V They,are soluble in water and lower alcohols, insol­uble in coal tar' hydrocarbons. Brij; 30 Js moderately lipophilic ;-Brij*35. is* h ydrophilic. -
