Ethoduomeens are also cationic in nature, and react as the Ethomeens do—but with increased cationic properties. Gen erally, their water solubility is somewhat greater than that of the corresponding Ethorneen containing the same ethylene oxide content. Mono- and di- substituted ammonium salts can be prepared by reacting the Ethoduomeens with organic or inor ganic acids.
Ethoquads a r e water soluble, cationic surface-active agents. They differ from usual quaternary ammonium compounds since the quaternized nitrogen holds two polyoxyethylene and two alkyl groups instead of four alkyl groups. T h e two polyoxyethylene groups impart additional water solubility over that obtained with similar Arquads or Ethomeens. At present Ethoquad 0/12, 0/15, C/12, C/15, 18/12, and 18/25 derived from t h e corresponding Ethomeens are available.
T h e E t h o m i d s ® are N , N-substituted fatty acid amides. The substituents being polyoxyethylene groups, T h e Ethomids are chemically neutral and rather unreactive.
T h e E t h o m e e n s " 3 are prepared from n-alkyl primary amines. They have a n ethylene oxide content ranging from 2 t o 50 moles per mole of amine.
Ethomids are stable in acid or alkaline solutions. They can be hydrolyzed with concentrated bases and acids under strenuous reaction conditions—the products of such hydrolysis are fatty acids and di-polyoxyethylene amines.

There are four Ethorneen groups, differing in t h e chain length and unsaturatioo of the n-alkyl chain. Members in each group differ in polyoxyethylene content. The " C " series comes from a primary coco amine; t h e " S " series from primary soya amine; the " T " series from tallow amine; the " 1 8 " series from stearylamine. The Ethomeens are cationic in nature, the degree depending on the ethylene oxide content. By reacting them with either organic or inorganic acids, substituted ammonium salts can be formed. T h e E t h o d u o m e e n s R } like Ethomeens, are reaction products of amines and ethylene oxide. The difference: Etfao-

T h e E t h o f a t s ® are a series of mono-fatty or rosin acid esters of polyoxyethylene glycols. These surface actrve agents are essentially 100 % active materials and being nonionics, they are compatible with anionic and cationic agents. RC—Ο

The Ethofats have emulsifying properties and some may be used alone as emulsifiers, whereas other members may be used with other agents to obtain improved emulsions. Besides serving as emulsifiers, the Ethofats are used as wetting a n d dispersing agents. Although fairly stable in mildly acid or alkaline solu tions, the Ethofats can be hydrolyzed with strong acids or alkalies. We urge you to investigate the Ethoquads, Ethomeens, Etho duomeens, Ethomids and Ethofats. Send today for samples and detailed information. Please indicate the application you are interested in so our technical staff can recommend specific chemicals for your testing.
