In the form of packets, yodofor formula has a long shelf life. However, iodine can be lost from the solution by evaporation. The rapid shrinkage occurs especially when the temperature exceeds 50⁰C solution because iodine tends to sublimate. Iodine can be absorbed by the objects of plastic and rubber from the heat exchanger to cause color. By iodine staining can be beneficial because most organic contaminants and minerals will be yellow, thus showing the locations where cleaning is not enough.
The red color of iodine solution provides visual evidence of the existence of sanitation, but the intensity of the color is not a reliable indicator of iodine concentration. Because yodofor acidic solution, this solution will prevent the accumulation of minerals, when used regularly. Mineral deposits are not removed by the application sanitaiser iodine. Organic materials (mainly milk) inactivation of iodine in solution memucatkan yodofor with red color.
The loss of iodine from a mild solution unless there is an organic contaminant in large quantities. Therefore, the loss of iodine increases during storage, this solution should be checked and regulated in accordance with the required strength. Iodine compounds are more expensive than chlorine. Loss of iodine compounds are these compounds volatile at 50 ° C and is very sensitive to changes in pH.
Sanitaiser iodine is effective for hand sanitation because these compounds do not irritate the skin. These compounds are especially recommended for those jobs in the hand dyeing plant is often used in the food and food handling equipment. Yodofor consists of a mixture of iodine with a surfactant that dissolves (usually non-ionic, anionic and cationic surfactants although it can be used) which acts as a carrier of iodine; This iodine which provide bactericidal activity.
Therefore, it can be referred to as sanitaiser yodofor-sterilizer though deterjennya power depends on the amount of surfactant in the mix. When yodofor used as a disinfectant, the surfactant is added to be more to improve deterjennya. Even though yodofor less affected by changes in pH than QACs, in practice, a component of acid, usually acid phosphate, is added to yodofor to lower the pH. This is because yodofor most active in the pH range 3-5 and phosphoric acid buffer in this range.
Yodofor rapidly lethal effect against a broad spektran bacteria and resembles hypochlorite in this regard, but these compounds also retain considerable activity in the presence of organic effluent with a pH of no more than 4 and the quantity of waste is not excessive, but yodofor, more or less active against spores than hypochlorite. Yodofor expensive and therefore not widely used; but these compounds are not corrosive, not irritant, not toxic and slightly smelly but should be rinsed well after use.
Some plastic materials can absorb iodine and become change color when exposed to these compounds; rubber also tend to absorb iodine so long time yodofor contact should be avoided to prevent the possibility of corrosion on the food. Yodofor One advantage of these compounds is not affected by hard water salts. Stable in concentrated form even with prolonged storage at room temperature high is still possible loss of activity.
Yodofor mainly used in the dairy industry, in which to add bakterisidalnya, phosphoric acid are useful in regulating the stone milk (milk stone); yodofor also used in the beer industry. In the CIP system may need to be added so that the foam formed by foaming surfactant that is easy / low for this purpose in the formulation. Operating temperatures up to 50⁰C can be used with iodine concentrations varying between 10 and 100 ppm.
