Abstract

The need for a container and detergent composition which exhibit good cleaning, including on greasy soils, and good surface shine, while also maintaining spray visibility on the treated hard surface, is met by formulating an aqueous detergent composition using a low level of surfactant system, an aminoalcohol solvent, and a glycol ether solvent, at the specified ratios.

First claim

What is claimed is:

1. A container comprising a spray applicator and a container-body, wherein the container-body comprises a detergent composition, the detergent composition comprising:
from about 0.5 to 5 wt. % of a surfactant system by weight of the detergent composition, wherein the surfactant system comprises:
a nonionic surfactant selected from the group consisting of branched alkoxylated nonionic surfactants, amine oxide surfactants, and mixtures thereof, and
less than about 0.3 wt. % anionic surfactant, wherein the surfactant system is essentially free of cationic surfactants;

from 0.55 to 10 wt. % of a blend of organic solvents comprising aminoalcohol and from 0.05 to 2 wt % of a glycol ether of:
Formula 1: R 1 O(R 2 O) n R 3 wherein:
R 1 comprises a linear or branched C 4 , C 5 or C 6 alkyl or a substituted or unsubstituted phenyl,
R 2 comprises ethyl or isopropyl,
R 3 comprises hydrogen or methyl,
n ranges from 1 to 3, or

Formula 2: R 4 O(R 5 O) m R 6 wherein:
R 4 comprises n-propyl or isopropyl,
R 5 comprises isopropyl
R 6 comprises hydrogen or methyl,

m ranges from 1 to 3; and
water, wherein:
the surfactant system and aminoalcohol solvent are present at a weight ratio of from about 1:1 to about 1:5; and the aminoalcohol and glycol ether solvent are present at a weight ratio of from about 7:1 to about 3:1.

2. A method of treating a hard surface, wherein the method comprises the step of spraying the hard surface using the container according to claim 1 , wherein the spray applicator comprises:
a. a nozzle orifice having a diameter of from about 0.15 mm to about 0.40 mm; and
b. pressure regulation such that the spray is applied with a precompression pressure of between about 250 kPa and about 650 kPa.

3. The container according to claim 1 , wherein the branched alkoxylated alcohol comprises from 4 to 6 ethoxylate units and from 4 to 6 propoxylate units.

4. The container according to claim 1 , wherein the aminoalcohol and glycol ether solvent are present at a weight ratio of from about 5:1 to about 3:1.

5. The container of claim 1 , wherein the detergent composition comprises less than 1.0 wt % abrasive particles.

6. The container of claim 1 , wherein the detergent composition comprises from between about 0.1 wt % to about 1.0 wt % glycol ether.

7. The container of claim 1 , wherein the detergent composition comprises from between about 0.25 wt % to about 0.75 wt % glycol ether.

8. The container of claim 1 , wherein the detergent composition comprises less than about 0.15 wt % of anionic surfactant.

9. The container of claim 1 , wherein the surfactant system comprises the nonionic surfactant present at a level of from about 0.1 wt % to about 1.0 wt % by weight of the detergent composition.

10. The container of claim 1 , wherein the surfactant system comprises the nonionic surfactant present at a level of from about 0.20 wt % to about 0.60 wt % by weight of the detergent composition.
