Abstract

Disclosed are aqueous, concentrated dilutable liquid cleaning compositions comprising one or more anionic surfactants, one or more non-ionic surfactants, and an electrolyte, preferably in combination with one or more amphoteric surfactants, having a total active matter higher than 45 wt % based on the sum of the surfactants above that exhibit a controllable viscosity profile that is satisfactory to the consumer while being easy to dilute, providing fast enough a diluted, a medium diluted or a highly diluted cleaning composition.

Claims (47)

1. A concentrated dilutable cleaning composition, comprising:

(a) one or more anionic surfactants, wherein the one or more anionic surfactants (a) is lauryl ether sulfate or a salt thereof,

(b) one or more amphoteric surfactants selected from the group consisting of amine oxides and betaines,

(c) one or more non-ionic surfactants comprising one or more polyethoxylated glycerin ester compounds which is a polyethoxylated glycerine ester composition comprising a mixture of compounds of Formula (IV), wherein Formula (IV) is:

wherein each one of m, n, or 1 represents, independently, a number of 0 to about 200,

wherein the sum of m, n and 1 is in the range of about 1 to about 200,

wherein B is a hydrogen atom or an acyl group represented by —CO—R′,

wherein R′ represents a hydrogen, an alkyl, or an alkenyl group with 3 to 21 carbon atoms, and

wherein the mixture comprises the following compounds i. to iv.:

i. at least one component is represented by Formula (IV), wherein, independently, one of the groups B represents an acyl group represented by —CO—R′ and the remaining groups represent H;

ii. at least one component is represented by Formula (IV), wherein, independently, two of the groups B represent an acyl group represented by —CO—R′ and the remaining groups represent H;

iii. at least one component is represented by Formula (IV), wherein, independently, each one of the groups B represents an acyl group represented by —CO—R′; and

iv. at least one component represented by Formula (IV), wherein each one of groups B represents H,

(d) an electrolyte,

and optionally

(e) one or more solvents,

(f) one or more pH adjuster agents,

and

(g) water up to about 100 wt % of the composition;

wherein the total active matter of the composition calculated from the sum of (a) the one or more anionic surfactants, (c) the one or more non-ionic surfactants, and (b) the one or more amphoteric surfactants is from about 45 wt % to less than 100 wt % taking as a whole the concentrated composition, and

wherein the amount of one or more non-ionic surfactants (c) is from 5 to 90 wt % with respect to the total active matter of the composition.

2. The concentrated dilutable cleaning composition according to claim 1 wherein the proportion by weight of the species (i):(ii):(iii) is in the range of about 46 parts to about 90 parts (i), about 9 parts to about 35 parts (ii), and about 1 part to about 15 parts (iii), respectively.

3. The concentrated dilutable cleaning composition according to claim 1 wherein the proportion by weight ((i)+(ii)+(iii)):(iv) is in the range of about 3.0:0.3 to about 0.5:3.0.

4. The concentrated dilutable cleaning composition according to claim 1 wherein each one of m, n, or l represents, independently, a number from 0 to 9,

wherein the sum of m, n and l is in the range of greater than 5 and less than 9,

wherein the acyl group is represented by —CO—R,

wherein R represents an alkyl or an alkenyl group, with 6 to 9 carbon atoms, and

wherein the proportion by weight of ((i)+(ii)+(iii)):(iv) is in the range of about 2.0:0.5 to about 0.5:3, and

wherein the proportion by weight of (i):(ii):(iii) is about 60 parts to about 90 parts (i):about 10 parts to about 35 parts (ii):less than about 10 parts (iii), respectively.

5. The concentrated dilutable cleaning composition according to claim 1 , wherein the electrolyte (d) is sodium chloride or magnesium chloride.

6. The concentrated dilutable cleaning composition according to claim 1 , wherein the composition has a viscosity at about 20° C. that is below 500 cps.

7. The concentrated dilutable cleaning composition of claim 1 , wherein the composition is diluted to obtain a diluted cleaning composition.

8. The concentrated dilutable cleaning composition of claim 1 , wherein the composition is diluted to obtain a medium diluted cleaning composition,

wherein the total active matter of the composition is from more than about 20 to about 35 wt %.

9. The concentrated dilutable cleaning composition of claim 8 , wherein the composition has a viscosity at about 20° C. that ranges from about 300 to about 3500 cps.

10. The concentrated dilutable cleaning composition of claim 1 , wherein the composition is diluted to obtain a highly diluted cleaning composition, and

wherein the total active matter of the composition is from more than about 5 to about 20 wt %.

11. The concentrated dilutable cleaning composition of claim 10 , wherein the composition has a viscosity at about 20° C. that ranges from about 200 to about 3500 cps.

12. A method to prepare a concentrated dilutable cleaning composition, wherein said method comprises the step of:

diluting the composition of claim 1 to obtain a diluted, a medium diluted or a highly diluted composition.

13. The method according to claim 12 , wherein said method further comprising the step of:

dissolving the one or more anionic surfactants (a), the one or more non-ionic surfactants (c), and the electrolyte (d) and the one or more amphoteric surfactants (b), the one or more solvents (e), and the one or more pH adjuster agents (f) in water.

14. A method of cleaning an object, said method comprising the step of:

contacting a surface of the object with the concentrated dilutable cleaning composition according to claim 1 ,

wherein the contacting results in cleaning the surface of the object.

15. The concentrated dilutable cleaning composition of claim 1 , wherein R′ has 5 to 17 carbon atoms.
