For the generic term poloxamer, these copolymers are commonly named with the letter P (for poloxamer) followed by three digits: the first two digits multiplied by 100 give the approximate molecular mass of the polyoxypropylene core, and the last digit multiplied by 10 gives the percentage polyoxyethylene content (e.g. P407 = poloxamer with a ...
The nominal chemical formula of P123 is HO(CH 2 CH 2 O) 20 (CH 2 CH(CH 3)O) 70 (CH 2 CH 2 O) 20 H, which corresponds to a molecular weight of around 5800 g/mol. Triblock copolymers based on PEO-PPO-PEO chains are known generically as poloxamer.
Most of the common uses of poloxamer 407 are related to its surfactant properties. For example, it is widely used in cosmetics for dissolving oily ingredients in water.It can also be found in multi-purpose contact lens cleaning solutions, where its purpose there is to help remove lipid films from the lens.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure.
Co-danthramer is dantron plus poloxamer. It is (in the U.K.) only to be prescribed to terminally ill patients because of its carcinogenicity in rats. It is often prescribed to people taking long term opioid, because it relaxes the effect of opioid induced constipation. It will not alleviate the symptoms of opioid induced delayed gastric ...
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products.. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone.

Ponceau 4R (known by more than 100 synonyms, [1]: 460–461 including as C.I. 16255, [2] cochineal red A, [2] C.I. acid red 18, [2] brilliant scarlet 3R, [2] brilliant scarlet 4R, [2] new coccine, [1]: 460 ) is a synthetic colourant that may be used as a food colouring.
An illustration shows the different effects of the bacteriostatic agent and bactericidal agent. A bacteriostatic agent or bacteriostat, abbreviated Bstatic, is a biological or chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise.
