Shampoo containing a gel network
A shampoo composition comprising: a) from about 5% to about 50% of one or more detersive surfactants, by weight of said shampoo composition; b) a dispersed solid crystalline gel network phase comprising: i) a first component comprising at least about 0.05% of one or more fatty acids by weight of said shampoo composition; ii) a second component comprising at least about 0.05% of one or more additional fatty amphiphiles by weight of said shampoo composition; iii) water; and c) at least about 20% of an aqueous carrier, by weight of said shampoo composition; wherein said first component is combined with said second component in the ratio of 10:1 to about 1:5 to form said solid crystalline gel network phase.
1. A shampoo composition comprising:
a) from about 5% to about 50% of one or more anionic detersive surfactants, by weight of said shampoo composition;
b) from about 5% to about 40% by weight of said shampoo composition of a pre-formed solid crystalline gel network phase consisting of:
i) a fatty acid or alkoxylated fatty acid having a structure of
wherein R1 is C10-40 and R 2 is a C 1 -C 5 carbon chain which can be branched or hydroxy substituted; and k is a number ranging from 0 to 5;
ii) from about 0.05% to about 14% of one or more fatty amphiphiles by weight of said shampoo composition, wherein said fatty amphiphile is a fatty alcohol comprising a hydrophobic tail group selected from an alkyl group of C 12 -C 70 length;
iii) water; and
wherein the weight ratio of said fatty acid or said alkoxylated fatty acid to said fatty alcohol is from about 10:1 to about 1:5 to form said pre-formed solid crystalline gel network phase; and
c) from about 20% to about 95% of an aqueous carrier, by weight of said shampoo composition.
2. A shampoo composition according to claim 1 , further comprising a deposition aid.
3. A shampoo composition according to claim 1 , wherein said deposition aid is a cationic polymer.
