Floor stripper/cleaner containing aliphatic acid-organic base pair
Floor finishes are stripped or deep scrubbed using a floor stripper/cleaner composition containing sparingly water-soluble floor finish solvent, water, C 10 aliphatic acid in an amount sufficient to provide a homogenous aqueous liquid phase during shaking, and sufficient organic amine so that the composition pH is more than 2 and less than 10 and the composition is not corrosive to skin.
1 . A floor finish stripper or scrub and recoat composition comprising:
a) sparingly water-soluble floor finish solvent;
b) water;
c) C 10 aliphatic acid in an amount sufficient to provide a homogenous aqueous liquid phase during shaking; and
d) sufficient organic amine so that the composition pH is more than 2 and less than 10 and the composition is not corrosive to skin.
2 . A composition according to claim 1 wherein the solvent comprises a dibasic ester, essential oil, dialkyl carbonate or mixture thereof.
3 . A composition according to claim 1 wherein the solvent comprises ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol phenyl ether, propylene glycol phenyl ether, or mixture thereof.
4 . A composition according to claim 1 wherein the solvent comprises benzyl alcohol.
5 . A composition according to claim 1 wherein the C 10 aliphatic acid comprises n-decanoic acid.
6 . A composition according to claim 1 wherein the amine comprises monoethanolamine.
7 . A composition according to claim 1 further comprising surfactant.
8 . A composition according to claim 1 having a pH more than 4 and less than 10.
9 . A composition according to claim 1 having a pH more than 5 and less than 9.
10 . A composition according to claim 1 comprising about 5 to about 85 wt. % solvent, about 1 to about 93 wt. % water, about 1 to about 25 wt. % C 10 aliphatic acid and about 1 to about 10 wt. % organic amine.
11 . A method for stripping or deep scrubbing a floor finish comprising:
a) applying to the floor finish a composition comprising sparingly water-soluble floor finish solvent, water, C 10 aliphatic acid in an amount sufficient to provide a homogenous aqueous liquid phase during shaking, and sufficient organic amine so that the composition pH is more than 2 and less than 10 and the composition is not corrosive to skin;
b) allowing the applied composition to soften, dissolve or clean the floor finish; and
c) removing the composition.
12 . A method according to claim 11 wherein the solvent comprises a dibasic ester, essential oil, dialkyl carbonate or mixture thereof.
13 . A method according to claim 11 wherein the solvent comprises ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, ethylene glycol phenyl ether, propylene glycol phenyl ether, or mixture thereof.
14 . A method according to claim 11 wherein the solvent comprises benzyl alcohol.
15 . A method according to claim 11 wherein the C 10 aliphatic acid comprises n-decanoic acid.
16 . A method according to claim 11 wherein the amine comprises monoethanolamine.
17 . A method according to claim 11 wherein the composition further comprises surfactant.
18 . A method according to claim 11 wherein the composition has a pH more than 4 and less than 10.
19 . A method according to claim 11 wherein the composition has a pH more than 5 and less than 9.
20 . A method according to claim 11 wherein the composition contains about 0.05 to about 25 wt. % solvent, about 25 to about 99 wt. % water, about 0.01 to about 6 wt. % C 10 aliphatic acid and about 0.01 to about 3 wt. % organic amine.
