## Abstract

A method of preparing a component of a personal care bar, the method comprising: (a) providing a composition comprising an isethionate surfactant at a temperature of at least 20° C.; (b) combining the composition comprising the isethionate surfactant with a synthetic 5 wax and optional further components at a temperature of at least 120° C.; and (c) cooling the mixture obtained in step (b).

## Claims

### Claim 1

A method of preparing a component of a personal care bar, the method comprising:
(a) providing a composition comprising an isethionate surfactant at a temperature of at least 120° C.;
(b) combining the composition comprising the isethionate surfactant with a synthetic wax and optional further components at a temperature of at least 120° C.; and
(c) cooling the mixture obtained in step (b).

### Claim 2 (depends on 1)

A method of preparing a personal care bar, the method comprising preparing a component of a personal care bar according to claim 1 and combining the component with a soap component and optional further ingredients.

### Claim 3

A method of preparing a personal care bar, the method comprising:
(a) providing a composition comprising an isethionate surfactant at a temperature of at least 120° C.;
(b) combining the composition comprising the isethionate surfactant with a synthetic wax and optional further components at a temperature of at least 120° C.; and
(c) cooling the mixture obtained in step (b) forming into chips; and
(d) combining the chips obtained in step (c) with chips of a soap component and optional further ingredients.

### Claim 4

A composition comprising an isethionate surfactant and an ethylene vinyl acetate copolymer.

### Claim 5 (depends on 4)

A component for a personal cleansing bar comprising a composition as claimed in claim 4.

### Claim 6

A personal cleansing bar comprising:
(i) an isethionate surfactant;
(ii) an ethylene vinyl acetate co-polymer; and
(iii) a soap component.

### Claim 7 (depends on 6)

A personal care bar according to claim 6 which further comprises one or more components selected from: fatty acids; salts of fatty acids; polyalkylene glycols and derivatives; starches and dextrins, maltodextrin and other carbohydrates; inorganic particulate materials for example talc, kaolin, bentonite clay, aluminosilicate clays or other clays; carbonate or sulphate salts; glycerol esters or ethylene glycol esters; sugars and crystalline polyols; other waxes and fatty alcohols; fragrances or perfumes; germicides; antimicrobial agents; antioxidants; cationic polymers; sequestering agents for example sodium ethylenediaminetetraacetate (EDTA) and trisodium ethylenediamine disuccinate (EDDS); pigments, colorants and dyes; opacifiers and pearlizers for example titanium dioxide, zinc stearate or magnesium stearate; emollients for example benzoate esters; additional anionic, cationic or amphoteric surfactants for example, betaines, taurates, alkyl ether carhoxylates, acyl glutamates, acyl sarcosinates, alkyl sulfates and alkyl ether sulfates; and additional water.

### Claim 8 (depends on 6, 7)

A personal cleansing bar according to claim 6 or claim 7 having a non-gritty feel.

### Claim 9 (depends on 1)

A method of producing a soap free personal cleansing bar, the method comprising forming the synthetic detergent containing component obtained by the method of claim 1 into a bar.

### Claim 10

A soap free personal cleansing bar comprising an isethionate surfactant and an ethylene vinyl acetate co-polymer.
