Reduced misting alkaline and neutral cleaning, sanitizing & disinfecting compositions
U.S. Patent No. 10,392,587
Ecolab USA Inc.
Ecolab USA Inc., St. Paul, MN, has patented alkaline sprayable aqueous compositions for cleaning, sanitizing and
disinfecting. In particular, the sprayable compositions include an inverse emulsion polymer to modify the viscosity
of the composition and provide numerous benefits over dispersion polymer compositions used for rheology
modification to reduce misting and respiratory inhalation of cleaning compositions. Compositions and methods
of cleaning using the compositions have reduced amounts of airborne particulates of the composition during
spray applications.
Use of nonionics as rheology modifiers in liquid cleaning solutions
U.S. Patent No. 10,005,984
Ecolab USA Inc.
Ecolab USA Inc., St. Paul, MN, has patented a liquid cleaning composition that is cocamide DEA-free, comprising
a nonionic surfactant; one or more coupling agents including a protic solvent, an aromatic sulfonate or
mixture thereof; a neutral salt; and a foam promotion or stabilizing agent comprising an alkyl dimethyl amine
oxide and an olefin sulfonate. The neutral salt includes Na+, K+, Rb+, Cs+, Mg2+, Ca2+, Sr2+, or Ba2+ as a
cation and Cl–, Br–, I–, ClO4–, BrO4–, ClO3–, or NO3– as an ion. The composition has less than 0.5% weight
of cocamide DEA.
