Povidone—iodine is a brown, water-soluble powder containing approximately 10% iodine. However, the amount of free iodine, which is responsible for the antimicrobial activity, is low in a concentrated solution, but is released as the solution is diluted (41). Concentrated solutions have actually been contaminated with bacteria (42). For use as an antiseptic, povidine—iodine is diluted with water or alcohol to a concentration of 1% iodine. Detergents are added if it is used as a surgical scmb. lodophors are important as broad-spectmm antiseptics for the skin, although they do not have the persistent action of some other antiseptics. They are also used as disinfectants for clinical thermometers that have been used by tuberculous patients, for surface disinfection of tables, etc, and for clean equipment in hospitals, food plants, and dairies, much as chlorine disinfectants are used.

Water-soluble powder admixtures which require mixing at the job site or point of use. Such job mixing may require that low-concentration solutions be made due to difficulty in mixing. 

Zinc Dithionite. Zinc dithionite [7779-86-4], ZnS204, is a white, water-soluble powder. Although it exhibits somewhat greater stability in aqueous solution compared to sodium dithionite at a given temperature and pH, it is no longer used in the United States because of regulatory constraints on pollution of water by zinc. 

Creatine monohydrate, the most popular form of off-the-shelf creatine supplementation, is an odorless, white, water-soluble powder. Its chemical name is N-(ammoimmomethyl)-N-methylglycine monohydrate.

The sodium salt of this acid may be prepared by dissolving 2.5 g of the acid in a solution of 0.23 g of sodium in 20 cc of ethyl alcohol, and the salt forms, after evaporating the alcohol, a colorless, water-soluble powder. 

The water resistance of partly water - soluble, powder-form explosives (e.g. ammonium nitrate explosives or blasting agents) can be improved by the addition of hydrophobic or gelling agents. If e.g. - Guar Gum is added, the water entering immediately forms a gel which blocks the penetration of more water. 

Pancreatin Obtained from porcine or bovine (ox) pancreatic tissue. Produced as a white to tan, water-soluble powder. Major active principles (1) a-amylase, (2) protease, and (3) lipase. Typical applications used in the preparation of precooked cereals, infant foods, and protein hydrolysates. 

Pepsin Obtained from the glandular layer of hog stomach. Produced as a white to light tan, water-soluble powder amber paste or clear, amber to brown, aqueous liquids. Major active principle pepsin. Typical applications used in the preparation of fishmeal and other protein hydrolysates and in the clotting of milk in manufacture of cheese (in combination with rennet). 

Synthetic colours can be supplied as water soluble powders, prepared solutions, easily dispersed granules, pastes or gelatine sticks. Blocks of colour in vegetable fat are also available for use in fat-based products. The attraction of soluble powders is that they are the least expensive and can be made up as required for use although the other forms have the advantage that they are at a concentration that is ready to use - the disadvantage with the pre-prepared versions is, however, usually financial.
