Fully water-dilutable microemulsions. |
摘要 |
Fully water-dilutable microemulsions are disclosed comprising comprising (A) an active ingredient which has a solubility in water of less than 1% at room temperature and a melting point of less than 100 DEG C; (B) a non-polar, water immiscible solvent capable of dissolving at least 5% by weight of (A) at room temperature; (C) a surfactant system comprising: (C1) at least one sulfated of sulfonated anionic surfactant having about 3-17% sulfation or sulfonation; and (C2) at least one ethoxylated surfactant; and (D) 0 to 99.9 % by weight water; the weight ratio of (C1) to (C2) being from 10/90 to 90/10; the weight ratio of said (A) to (B) being from 95/5 to 1/99, and the weight ratio of said (A) to (C) being from 1/99 to 86/14; said composition being thermodynamically stable and clear, opalescent, or only slightly cloudy at all levels of water dilution up to 99.9%. The microemulsions are particularly useful in areas where preservation is required. |
