## Abstract

The present invention relates to a sprayable composition for providing a translucent, transparent, semi-transparent or opaque sprayable hair product which exhibits a high level of hold and rigidity to hair such that hair can be held in a particular position for prolonged periods of time without unnatural hardness, superior retention of shape in conditions of heat and humidity, and imparting thickness and body compared to current hairsprays; the composition comprising: a propellant and at least one binder, wherein at least one binder comprises an ethylene vinyl alkanoate copolymer with a weight percent of vinyl alkanoate in the copolymer within the range of 19 wt % to 42 wt %. The invention is also related to the apparatus comprising a container containing the sprayable composition, the methods for forming a coating on a surface and, particularly, the corresponding methods for styling hair, as well as the use of at least one binder in a manufacture of a sprayable composition for styling hair, wherein at least one binder is an ethylene-vinyl alkanoate copolymer with a weight percent of vinyl alkanoate in the copolymer within the range of 19 wt % to 42 wt %.

## Claims

### Claim 1

A sprayable composition comprising a propellant and at least one binder being an ethylene vinly alkanoate copolymer, characterised in that the ethylene vinyl alkanoate copolymer is a random copolymer of ethylene and vinyl alkanoate having a vinyl acetate content within the range of 40 wt % to 42 wt %.

### Claim 2 (depends on 1)

The sprayable composition of claim 1, wherein the propellant is present in an amount within the range of 80 wt % to 99 wt %.

### Claim 3 (depends on 1)

The sprayable composition of claim 1, wherein the propellant is selected from dimethyl ether, liquefied petroleum gas, or a combination thereof.

### Claim 4 (depends on 1)

The sprayable composition of claim 1, wherein the composition further comprises a solvent.

### Claim 5 (depends on 1)

The sprayable composition of claim 1, wherein the composition further comprising an additive selected from the group consisting of dyes, oils, perfumes, surfactants, fire retardants, metal powders/particles such as copper, silver and gold, conditioners such as humectants, sunscreen, moisturisers, acidifiers, lubricants, preservatives, antistatic agents, and wax.

### Claim 6 (depends on 1)

The sprayable composition of claim 1, wherein the composition further comprising fibres.

### Claim 7 (depends on 1)

A method for forming a coating on a surface, the method comprising:
(i) spraying the composition of claim 1 on to the surface; and
(ii) allowing the propellant in the composition sprayed on the surface to evaporate.

### Claim 8 (depends on 7)

The method according to claim 7, wherein the surface is human or animal hair.

### Claim 9 (depends on 1)

A method for styling hair, the method comprising:
(i) spraying the composition of claim 1 on hair;
(ii) styling the hair; and
(iii) allowing the propellant to evaporate.
