Quaternary ammonium salts or quaternary ammonium compounds called quaternary amines in oilfield parlance are salts of quaternary ammonium cations. Polyquats are a variety of engineered polymer forms which provide multiple quat molecules within a larger molecule. Quats are used in consumer applications including as antimicrobials such as detergents and disinfectants , fabric softeners , and hair conditioners. Quats tend to be gentler on surfaces than bleach -based disinfectants, and are generally fabric-safe. Quaternary ammonium compounds are prepared by the alkylation of tertiary amine.

This hormone is produced throughout pregnancy and is especially vital during the early stages. Because it begins to rise rapidly in early pregnancy, testing for the presence of hCG in urine is one of the primary ways to determine whether or not an individual is pregnant. Throughout pregnancy, doctors may also test hCG levels as a way to monitor the health of a pregnancy. To help, here is a look at everything you need to know about hCG including what it is, how to test for it, and how high your hCG levels should be throughout pregnancy. Its primary role is to stimulate the corpus luteum to increase the production of progesterone, which in turn helps to:. Initially, hCG is produced by the cells that surround a developing embryo. The placenta then takes over the production of hCG once it is formed, and it then continues to produce hCG throughout pregnancy.
