## Abstract

Use of a serum comprising a lubricant for anti-aging of clothes.

## Claims

### Claim 1

(canceled)

### Claim 2 (depends on 17)

The method of claim 17, wherein the lubricant is a silicone.

### Claim 3 (depends on 17)

The method of claim 17, wherein the lubricant is a silicone having a molecular weight of 1,000 to 500,000.

### Claim 4 (depends on 2)

The method of claim 2, wherein the silicone is in the form of an emulsion.

### Claim 5 (depends on 4)

The method of claim 4, wherein the particle size of the emulsion is in the range from 1 nm to 100 microns.

### Claim 6 (depends on 17)

The method of claim 17, wherein the lubricant is selected from polydiakylsiloxanes and anionic functionalised silicones.

### Claim 7 (depends on 17)

The method of claim 17, wherein the lubricant is selected from polydimethylsiloxane (PDMS) and carboxy functionalised silicones.

### Claim 8 (depends on 17)

The method of claim 17, wherein the serum further comprises a cationic polymer.

### Claim 9 (depends on 8)

The method of claim 8, wherein the laundry composition comprises 0.25 to 10 w.t. % cationic polymer.

### Claim 10 (depends on 8)

The method of claim 8, wherein the cationic polymer has a molecular weight greater than 20 000 g/mol.

### Claim 11 (depends on 8)

The method of claim 8, wherein the cationic polymer is selected from cationic polysaccharide polymers and acrylate polymers.

### Claim 12 (depends on 17)

The method of claim 17, wherein the serum further comprises a perfume.

### Claim 13 (depends on 17)

The method of claim 17, wherein the serum floats on the laundry liquid with which it is used.

### Claim 14

(canceled)

### Claim 15 (depends on 17)

The method of claim 17, comprising the steps of:
a. Pouring the laundry liquid into a washing machine drawer, drum or a dosing shuttle and
b. Pouring the serum composition according to any preceding claim on top of the laundry liquid.

### Claim 16 (depends on 17)

The method of claim 17, wherein the serum is a Squid product which is added to the laundry process at the same time as the laundry detergent and/or a fabric conditioner.

### Claim 17

A method comprising applying to clothes a combined composition for anti-aging of clothes, wherein the combined composition comprises,
i) a liquid serum, and
ii) at least one laundry liquid selected from a laundry detergent and a fabric conditioner,
wherein the serum comprises 1-60 w.t. % lubricant; and
wherein the serum comprises less than 4 w.t. % surfactant.

### Claim 18 (depends on 17)

The method of claim 17, wherein the laundry liquid is a laundry detergent and a fabric conditioner.
