Benefits of technology

This new type of liquid oily substance called alpha hydroxypropyltrimethylammonium chloride (αHTPAM) can be used for making products that are easy to dissolve or disintegrate when mixed into water without losing their effectiveness due to its low solubility properties during use. By doing this, it becomes easier than previous methods like adding surfactants to make them work better.

Problems solved by technology

This patented describes how certain types of compounds called aminosilsoluble organopolymers (AOS) have been found that could form microsphericles when mixed together during solid phase reactions or dissolved in solvents like water. These particles were able to stick tightly onto fibers without sticking them out from their surfaces. They also had good properties such as being easy to handle at different stages of processing steps.
