Calculating Cleaning Agent Safety Based Limits

01 October 2014

Q. Does Alconox provide information on calculating cleaning agent safety based limits? A. Cleaning agent safety based limits are typically calculated from a safety factor of an acceptable daily intake (ADI), a (1/1000 or more) reduction of an LD50 preferably by the same route of administration, or reproductive hazard levels. Alconox, Inc Pharmaceutical Cleaning Validation References PDF has an entire section dedicated to cleaning agent safety based limits.

Water Hardness and Alconox Texture

30 September 2014

Q. We have had a customer call and say the product is not “sudsy & slimy” like it usually is. A. Variations in normal water hardness will not impact the detergency of Alconox, but they can change the foam and feel of a solution. If the client has had any change in the hardness (amount of calcium and magnesium in the water) of their water used to make solutions, this can cause changes in the "slipperyness" and foaminess of the solution. Harder water will make less foam because the calcium and magnesium ions in the water form insoluble dodecylbenzene sulfonate soaps that must be dispersed and emulsified by the cleaner, thereby depleting available foam making ingredients.

Cleaning Aluminum without Corrosion

24 September 2014

Q. How is galvanic corrosion prevented when cleaning aluminum? A. Aluminum is an active metal that is somewhat high on the "anodic index" of the galvanic series. If aluminum is cleaned with other metals present, you can create a battery and get galvanic corrosion. Aluminum should not be cleaned in the presence of metals that are significantly higher or lower on the anodic series; higher on the anodic scale such as zinc, magnesium or beryllium metals and lower on the anodic scale such as tin, brass, bronze, copper, silver, nickel and rhodium.

Cleaning Aluminum with Alconox

18 September 2014

Q. Which Alconox cleaners can be used on Aluminum? A. The Alconox brand cleaners recommended for cleaning aluminum are Alconox, Liquinox, Tergazyme, Alcojet, Alcotabs, Detojet, Citranox, Luminox, Citrajet, Solujet and Tergajet. Detergent 8 is not recommended for cleaning aluminum. Aluminum forms a natural passive layer in air that allows it to be successfully cleaned without adverse reactions with cleaner. A passive layer forms in under an hour, provided there is no oily film present. Once the passive layer is formed, the recommended Alconox brand cleaners can be used to clean the aluminum at concentrations of less than 5% at 90 deg C or less for up to one hour.
