Abstract
A new stable liquid suspension containing non-soluble particles dispersed in a non-aqueous liquid medium having a concentration of a suspension aid and a method of making and use thereof.
Claims36
A non-aqueous suspension comprising:
- non-soluble particles dispersed in a non-aqueous liquid medium having a concentration of a suspension aid wherein said non-aqueous liquid medium is selected from the group consisting of glycols, polyglycols, glycol ethers, glycol esters, and glycol ether esters and wherein said suspension aid is selected from the group consisting of hydroxypropyl cellulose, ethyl cellulose, polyvinyl pyrrolidone, polyacrylic acid and copolymers of polyvinyl pyrrolidone and acrylic acid.
A stable liquid suspension comprising:
- a liquid phase comprising a liquid medium selected from the group consisting of glycols, polyglycols, glycol ethers, glycol esters and glycol ether esters;
- non-soluble particles;
- and
- a stabilizing amount of a suspension aid sufficient to enhance the suspension of said non-soluble polymer particles in said liquid phase.
1 more element
A method of preparing a non-aqueous suspension, comprising the steps of:
- mixing non-soluble particles, a suspension aid, and a liquid medium selected from the group consisting of glycols, polyglycols, glycol ethers, glycol esters and glycol ether esters to thereby form said non-aqueous suspension.
A method of preparing a non-aqueous liquid suspension, said method comprises the steps of:
- mixing non-soluble particles with a liquid medium and adding thereto a stabilizing amount of a suspension aid sufficient to enhance the suspension of said non-soluble particles in said liquid medium.
