## Abstract

Provided are compositions suitable as hair styling compositions. Said compositions may comprise (a) at least one salt selected from the group consisting of sodium chloride, magnesium sulfate, calcium chloride, calcium phosphate and combinations thereof; and (b) at least one polyglyceryl ester having a structure represented by: wherein: R1 and R2 are each independently an alkenyl group having 9-21 carbon atoms and at least one unsaturated carbon-carbon bond, G is CH2—CH(OH)—CH2O, and n ranges from 1 to 15. Also provided are kits and methods of using said compositions.

## Claims

### Claim 1

A composition comprising:
a. about 2 to 9% by weight of magnesium sulfate;
b. about 3 to 11% by weight of sodium chloride; and
c. about 0.4 to 5.0% by weight of a polyglyceryl dioleate ester,
wherein the composition does not comprise a surfactant other than the polyglyceryl ester and does not comprise terpolymers of vinyl pyrrolidone, and wherein the composition has a viscosity up to about 50 cP at 20° C., and
wherein the composition provides hair with curl definition, shine, and frizz control, while maintaining softness of the hair.

### Claim 2 (depends on 1)

The composition of claim 1, wherein the polyglyceryl dioleate ester comprises polyglyceryl-10 dioleate.

### Claim 3 (depends on 1)

The composition of claim 1, wherein the composition further comprises a cosmetically suitable additive.

### Claim 4 (depends on 1)

The composition of claim 1, further comprising about 60-95% by weight of the composition of water.

### Claim 5 (depends on 1)

The composition of claim 1, wherein the composition has a viscosity up to about 5 cP at 20° C.

### Claim 6

A hair styling composition consisting of:
a. water;
b. magnesium sulfate;
c. sodium chloride; and
wherein a total amount of magnesium sulfate and sodium chloride is from about 4 to 20% by weight,
d. about 0.4 to 5.0% by weight of a polyglyceryl dioleate ester;
e. one or more preservatives;
f. optionally, sodium hydroxide;
g. optionally, one or more natural extracts; and
h. optionally, dextrin.

### Claim 7 (depends on 6)

The composition of claim 6, wherein the polyglyceryl dioleate ester comprises polyglyceryl-10 dioleate.

### Claim 8

A hair styling composition consisting of:
a. about 60-95% by weight of the composition of water;
b. about 2 to 9% by weight of the composition of magnesium sulfate;
c. about 3 to 11% by weight of the composition of sodium chloride;
d. about 0.4 to 5.0% by weight of the composition of polyglyceryl-10 dioleate;
e. one or more preservatives;
f. sodium hydroxide;
g. one or more natural extracts; and
h. dextrin.

### Claim 9 (depends on 1)

A kit comprising the composition of claim 1 in a spray bottle.

### Claim 10 (depends on 1)

A method of styling hair, the method comprising applying to the hair the composition of claim 1.

### Claim 11 (depends on 10)

The method of claim 10, wherein applying the composition comprises spraying the composition onto the hair.

### Claim 12 (depends on 8)

A method of styling hair, the method comprising applying to the hair the composition of claim 8.

### Claim 13 (depends on 1)
