Stable aqueous detergent gels wholly or predominantly in hexagonal liquid crystal form contain a principal non-ethoxylated non-soap anionic surfactant in which the head group is positioned terminally or next-to-terminally on a hydrocarbon chain, for example, a primary alkyl sulphate or an alpha-olefin sulphonate, together with either an auxiliary surfactant or a specified additive. |
