    摘要: A method to enhance solubility of an active compound comprises combining an active compound, having an aqueous solubility that is less than or equal to about 10 mg/mL, and an amount of methoxypolyethylene glycol that is sufficient to increase the aqueous solubility of the active compound. Enhancement of aqueous solubility for this combination may be significantly greater than that of an active compound in combination with an equivalent amount of polyethylene glycol. Particularly enhanced solubility is shown where a small amount of water is also included. The invention may be used in a wide variety of applications, such as for pharmaceutical, agricultural, antimicrobial, and personal care products.

    摘要: Disclosed are compositions of the formula wherein R1 and R2 are each independently hydrogen or a linear or branched alkyl group containing from (1) to about (18) carbon atoms, provided that R1 and R2 together contain from about (8) to about (18) carbon atoms, and further provided that less than about 10 mole percent of R1 or R2 is hydrogen; R3 is hydrogen or an alkyl radical containing from (1) to about (6) carbon atoms; R4 and R5 are each independently hydrogen or an alkyl radical containing from (2) to about (6) carbon atoms, provided that R4 and R5 together contain from (2) to about (6) carbon atoms; m is an average value ranging from (0) to about (10), and n is an average value ranging from about (3) to (about 40), provided that the group containing m and the group containing n may be exchanged with one another as to position; and z is an average value ranging from about (0.5) to about (5). These compositions are conveniently prepared by a process including at least two steps and are useful as surfactants.
