Methods of cleaning equipment such as hand tools dirtied by bituminous mixture. A biodiesel emulsion comprising biodiesel, water and emulsifier(s), is applied to the surface of the equipment for a period of time (e.g., at least about 15 minutes) and optionally agitated. The biodiesel emulsion produces cleaning properties comparable to straight biodiesel, at a cost reduction, due to the replacement of biodiesel with water.

The disclosed invention relates to a two-part liquid composition for cleaning and disinfecting a substrate, comprising: (A) a disinfectant medium comprising peracetic acid; and (B) a supplemental medium comprising a non-enzymatic cleaner, a corrosion inhibitor, and a chelator. The supplemental medium (B) may further comprise an enzymatic cleaner, a surfactant, a buffer, a pH modifier, or a mixture of two or more thereof. The substrate may be a medical device, for example, an endoscope.

A system, non-transitory computer readable medium, and method are provided for determining patient care services for a patient being treated for a life-threatening or life-limiting progressive illness. Patient symptoms are identified by receiving data comprising personal health information of a patient. The level of distress of the patient is determined by analyzing the data comprising personal health information of the patent. A score is established based on criteria comprising the level of distress of the patient and a severity of the patient symptoms. The score correlates the level of distress of the patient with a clinical course of the life-threatening or life-limiting progressive illness. One or more patient care services appropriate for the clinical course of the life-threatening or life-limiting progressive illness and the level of distress of the patient is determined based on the score.

Solid rinsing, cleaning and/or sanitizing compositions for various applications are provided. In particular, solid compositions include a complex of urea and an acid having desirable storage stability previously unavailable in solid urea/acid compositions. Stable solid compositions are disclosed and methods of making the same to overcome conventional limitations associated with forming kinetically and thermodynamically stable solids that utilize urea/acid compositions.

Methods employing detergent compositions effective for reducing hard water scale and accumulation on hard surfaces, namely within food, beverage and pharmaceutical applications are disclosed. The detergent compositions employ phosphinosuccinic acid adducts in combination with an alkalinity source and optionally polymers, surfactants and/or oxidizers, providing alkaline compositions having a pH between about 10 and 13.5.

A solution for treating contact lens is provided. The solution includes about 0.01-1.0 parts by weight (pbw) of a polymer having phosphorylcholine groups, about 0.01-1 pbw of an inorganic salt, and about 100 pbw of water. The polymer has a number-average molecular weight of about 4,000 to about 1,000,000 daltons and has a structure of formula (I): ##STR00001##
wherein, in formula (I), m is a positive integer, n is zero or a positive integer, and R is C.sub.2-C.sub.12 alkyl group or C.sub.2-C.sub.12 hydroxyalkyl group. When n is a positive integer, m/n is greater than 1.
