In the current view of consumption, some consumers want to buy are inexpensive, that means something cheap, but the quality is good. Then many people also raised the voice of opposition, the main view of this part of the crowd is that you want to buy good quality with low prices is not realistic, each object should have his value, like cosmetics which is used in the face,it should be more expensive. Then someone would ask,are there cheap things really existing?The answer is of course yes. But are this things more, no,they are definitely less.
This reminds me of a customer, I repeatedly dealt with him for a long time, and finally because of the price we did not make an cooperation. The customer he is the first type of consumer, who wants to use lower prices to buy high-quality goods. In fact, we have to provide him with the best price, but he is still not satisfied with the status quo. Then it is not necessary to struggle with someone like this.
In short, today we want to say that we can provide you with the best quality products at the same time the price is consistent with, in a way, our PVP K90 is also perfect. If you are interested, please contact us. What are the specific issues, we will provide you with detailed answers.
Report--what is PVP?
Povidone (polyvinylpyrrolidone, PVP) is used in the pharmaceutical industry as a synthetic polymer vehicle for dispersing and suspending drugs. It also acts as a disintegrant and tablet binder. It appears as white to off-white hygroscopic powder in its pure form and is readily soluble in water. Povidone has the molecular formula of (C6H9NO)n. Povidone formulations are widely used in the pharmaceutical industry due to their ability to dissolve in both water and oil solvents.(from Drugs.com)
Povidone’s most common use is in the topical povidone-iodine solution (Aerodine, Betadine), where iodine is released as an antiseptic. Povidone-iodine is often used to prevent surgical incision infections. Povidone has also been used as blood volume expander and as an antibacterial in dental procedures. Chlorhexidine-alcohol is also used topically as a pre-operative surgical antiseptic and has been shown in one study to have slightly better antimicrobial activity.(from Drugs.com)
PVP is cleared for the following uses : as a clarifying agent in beverages and vinegar; as a tableting adjuvant; and as a stabilizer, bodying agent, and dispersant in nonnutritive sweeteners in concentrated liquid form, and vitamin and mineral concentrates. It is also cleared for use in packaging that comes in contact with various foods (Rothschild 1991). Robinson et al. (1990) reported that PVP K30 (average MW 40, 000) is used as a food additive. In 1986, the 30th Joint Expert Committee on Food Additives (JECFA) set an acceptable daily intake (ADI) level for PVP of 0-50 mg/kg (World Health Organization 1986b). At the 29th meeting, the committee had acknowledged the possibility of a hydrazine contaminant in PVP K-30 (a possible by-product of the polymerization process). In a 1987 report on hydrazine, the LARC working group declared that although there was "inadequate" evidence of carcinogenicity in humans, there was "sufficient" evidence of carcinogenicity in animals, citing studies in which rodents were exposed via inhalation and the oral route. However, the 29th JECFA stated,"the probability of carcinogenic effects arising from such low levels of hydrazine seems remote in view of the large amount of data that indicate that polyvinylpyrrolidone itself is not a carcinogen"(World Health Organization 1986a).
