## Abstract

A personal care composition comprising: i) a cleaning phase comprising a cleansing anionic surfactant which is a salt and comprises an alkyl group with from 8 to 14 carbons; ii) an aqueous conditioning gel network having no overall charge or being anionic, the gel network comprising: (a) fatty material; (b) a gel network anionic surfactant comprising an alkyl group with from 16 to 30 carbons; (c) cationic surfactant; (d) an active material selected from fragrances, vitamins, sunscreens and cooling agents; and iii) a cationic deposition polymer.

## Claims

### Claim 1

A method of manufacturing a hair care composition comprising the steps of
i) forming an aqueous conditioning gel network which has no overall charge or is anionic, the gel network comprising:
(a) fatty material;
(b) a gel network anionic surfactant comprising an alkyl group with from 16 to 30 carbons;
(c) cationic surfactant;
(d) an active material selected from the group consisting of fragrances, pest repellents, vitamins, sunscreens and cooling agents and mixtures thereof; and
ii) adding the resulting gel network to diluted primary surfactant solution
wherein the fatty material is selected from a group consisting of fatty alcohols, fatty esters, fatty acids, and fatty amides, having straight chain or branched, and having from 14 to 30 carbons,
wherein the ratio between (a) and (b) within the conditioning gel network is from 1.2:1 to 50:1, and
wherein the ratio between (b) and (c) within the conditioning gel network is from 9:1 to 13:1.

### Claim 2 (depends on 1)

A method according to claim 1 wherein the gel network anionic surfactant has from 16 to 22 carbons.

### Claim 3 (depends on 1)

A method according to claim 1 wherein the gel network cationic surfactant has from 16 to 30 carbons.

### Claim 4 (depends on 1)

A method according to claim 1 in which the active material is a fragrance.

### Claim 5 (depends on 1)

A method according to claim 1 in which the composition further comprises a suspending agent.

### Claim 6 (depends on 1)

A method according to claim 1 wherein the composition further comprises a cleansing anionic surfactant which is a sulphate, sulphonate, sarcosinate or isethionate.

### Claim 7 (depends on 1)

A method as described in claim 1 in which the composition further comprises a cationic deposition polymer.

### Claim 8 (depends on 1)

A process for gradual release of an active material to the body and/or hair comprising the step of applying to the body and/or hair a composition as described in claim 1.
