Abstract

A cleansing article having a substrate capable of absorbing and retaining a fluid therein, the substrate being impregnated with a cleaning composition containing a hydroxy mixed ether.

Claims (18)

1. A wet wipe comprising a substrate capable of absorbing and retaining a fluid therein, the substrate being impregnated with a cleaning composition comprising:

(a) from about 0.01 to about 2% by weight, based on the weight of the wet wipe, of at least one hydroxy mixed ether of formula (I),

wherein R 1 is a linear or branched alkyl moiety having 2 to 18 carbon atoms, R 2 is hydrogen or a linear or branched alkyl moiety having 2 to 18 carbon atoms, R 3 is hydrogen, R 4 is a linear or branched, alkyl and/or alkenyl moiety having 1 to 22 carbon atoms and n is a number from 1 to 50, provided that the sum of the carbon atoms in the moieties R 1 and R 2 is at least 4, and

(b) at least one surfactant other than (a), selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and combinations thereof;

wherein, when contacting a surface, said wet wipe provides improved cleaning and shine retention compared to wipes impregnated with alcohol ethoxylates.

2. The wet wipe of claim 1 wherein the hydroxy mixed ether (a) is present in the composition in an amount of from about 0.5 to 1% by weight, based on the weight of the wet wipe.

3. The wet wipe of claim 1 wherein the surfactant (b) comprises an alkyl and/or alkenyl oligoglycoside.

4. The wet wipe of claim 3 wherein said alkyl and/or alkenyl oligoglycoside is present in the composition in an amount of from about 0.05 to 2% by weight, based on the weight of the wet wipe.

5. The wet wipe of claim 3 wherein said alkyl and/or alkenyl oligoglycoside is present in the composition in an amount of from about 0.5 to 1% by weight, based on the weight of the wet wipe.

6. A process for cleaning a hard surface comprising contacting the hard surface with a wet wipe comprising a substrate capable of absorbing and retaining a fluid therein, the substrate being impregnated with a cleaning composition comprising:

(a) from about 0.01 to about 2% by weight, based on the weight of the wet wipe, of at least one hydroxy mixed ether of formula (I),

wherein R 1 is a linear or branched alkyl moiety having 2 to 18 carbon atoms, R 2 is hydrogen or a linear or branched alkyl moiety having 2 to 18 carbon atoms, R 3 is hydrogen, R 4 is a linear or branched, alkyl and/or alkenyl moiety having 1 to 22 carbon atoms and n is a number from 1 to 50, provided that the sum of the carbon atoms in the moieties R 1 and R 2 is at least 4, and

(b) at least one surfactant other than (a), selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and combinations thereof;

whereby improved cleaning and shine retention are provided compared to wipes impregnated with alcohol ethoxylate.

7. The process of claim 6 wherein the hydroxy mixed ether (a) is present in the composition in an amount of from about 0.5 to 1% by weight, based on the weight of the wet wipe.

8. The process of claim 6 wherein the surfactant (b) comprises an alkyl and/or alkenyl oligoglycoside.

9. The process of claim 8 wherein said alkyl and/or alkenyl oligoglycoside is present in the composition in an amount of from about 0.05 to 2% by weight, based on the weight of the wet wipe.

10. The process of claim 8 wherein said alkyl and/or alkenyl oligoglycoside is present in the composition in an amount of from about 0.5 to 1% by weight, based on the weight of the wet wipe.
