METHOD AND SYSTEM FOR PREPARING HYPOCHLOROUS ACID SOLUTIONS WITH PROLONGED SHELF-LIFE
The invention relates generally to disinfecting solutions and, more particularly, to systems and methods for producing disinfecting solutions having a prolonged shelf life. One embodiment provides a system comprising: a dispensing device; a chlorine-containing liquid or powder contained within the dispensing device; a container affixed to the dispensing device; and a receiving liquid within the container, wherein the dispensing device is adapted to deliver the chlorine-containing liquid or powder directly into the container.
LOW REACTIVITY CALCIUM HYPOCHLORITE SHAPED ARTICLE
It has now been discovered that a shaped article containing calcium hypochlorite has low reactivity in handling, storage and transportation as well as has a favorable dissolution (solubility) profile, when the shaped article contains lime and a hydrated magnesium sulfate. The shaped article has a NFPA rating of Class 1 oxidizer and is a non-Division 5.1 oxidizer.
Intercalated bleach compositions, related methods of manufacture and use
The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula M.sub.x(OCl).sub.y(O).sub.m(OH).sub.n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is 3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.
