摘要:
Anhydrous fatty alcohol sulfuric acid or ethoxylated fatty alcohol sulfuric acid is neutralized with dry sodium carbonate powder in the presence of powdered sodium tripolyphosphate in a high shear mixer. The dry, powdered, neutralized reaction product is stored until required for use in the manufacture of a detergent bar whereupon the powder is mixed with liquid ingredients for the detergent bar and subjected to conventional manufacturing steps for a detergent bar. Other dry, powdered ingredients for the detergent bar may be introduced at the high shear mixer.
摘要:
Mixtures of C.sub.6 -C.sub.20 alkane and olefin sulphonates having better colour than mixtures of the individually produced detergent actives are prepared by subjecting an alpha-olefin feedstock to sequential sulphonation and sulphitation.
摘要:
A heavy duty detergent powder and a process for producing the heavy duty detergent powder which comprises neutralizing a fatty acid having, optionally, dissolved therein at least one nonionic surface active agent with a powdered hydrous sodium carbonate at a temperature higher than the melting point of the fatty acid are disclosed.
摘要:
Flowable pasty raw materials for detergents capable of being pumped and having a content of washing active substance of more than 60% are obtained by neutralizing organic sulfuric acid semiesters or sulfonic acids with alkalies. Before neutralization the sulfuric acid semi-esters or sulfonic acids are degassed and neutralization is carried out in a continuous flow mixer. The greater proportion of the mixture is conducted in a cycle whereas a smaller proportion is withdrawn as finished product. In the continuous flow mixer the usual buffer substances and preserving agents may be added to the products.

NOVEL PARTICULATE BLENDS OF SOAP AND LIQUID NONIONIC SURFACTANTS AND A METHOD FOR PREPARING SAME, IS DISCLOSED. THE NEW METHOD INCLUDES THE COMBINATION OF AN APPROPPRIATE FATTY ACID WITH THE LIQUID NONIONIC SURFACTANT BEFORE SAPONIFICATION OF THE AICD. THE NOVEL PARTICULATE BLENDS ARE DRY, NON-TACKY AND FREE FLOWING AND ARE SUITABLE FOR POST ADDITION TO SPRAY DRIED DETERGENT POWDERS OR FOR USE BY THEMSELVES OR WITH BUILDERS AS FINAL DETERGENT FORMULATIONS.
