Detailed Description

Among what we manufacture is Pharmaceutical Grade Urea. Urea-containing creams are used as topical dermatological products to promote rehydration of the skin. Urea 40% is indicated for psoriasisxerosisonychomycosisichthyosiseczemakeratosiskeratoderma, corns, and calluses. If covered by an occlusive dressing, 40% urea preparations may also be used for nonsurgical debridement of nails. Urea 40% "dissolves the intercellular matrix"[10] of the nail plate. Only diseased or dystrophic nails are removed, as there is no effect on healthy portions of the nail. This drug is also used as an earwax removal aid.

Urea has also been studied as a diuretic. It was first used Dr. W. Friedrich in 1892. In a 2010 study of ICU patients, urea was used to treat euvolemic hyponatremia and was found a safe, inexpensive, and simple.

Like saline, urea injection has previously been used to perform abortion.

The blood urea nitrogen (BUN) test is a measure of the amount of nitrogen in the blood that comes from urea. It is used as a marker of renal function, though it is inferior to other markers such as creatinine because blood urea levels are influenced by other factors such as diet and dehydration.

Urea labeled with carbon-14 or carbon-13 is used in the urea breath test, which is used to detect the presence of the bacteria Helicobacter pylori (H. pylori) in the stomach and duodenum of humans, associated with peptic ulcers. The test detects the characteristic enzyme urease, produced by H. pylori, by a reaction that produces ammonia from urea. This increases the pH (reduces acidity) of the stomach environment around the bacteria. Similar bacteria species to H. pylori can be identified by the same test in animals such as apesdogs, and cats (including big cats).

Beijing Keephway Technology Co. has been engaged in R&D and manufacture of Fine Chemicals since its establishment in 2009.

Since the first day we entered the industry, all procedures from raw materials procurement, production and inspection, to the last step of packaging are conducted with the state-of-the-art technologies and highest standards.

We provide fine chemicals to a variety of industries, e.g. Cosmetics, Water Treatment, Pharmaceuticals, Printing & Dyeing, Agriculture, etc.

In 2014, we were awarded the title AAA First-class Enterprise (it means business is a demonstration unit with top-ranking expertise and credibility) and in the same year we were invited to be a member of the CFCRMIIA (The China Fine Chemical Raw Materials & Intermediate Industry Association).

Over the years, we have exported fine chemicals to markets all over the world, amongst are that of U.S., Germany, Republic of Korea, Malaysia, India, etc. and received a lot of positive feedback.
