Abstract
Storage-stable, pseudoplastic free-flowing cosmetic compositions/formulations, for example shampoos, shower and exfoliating gels and hair lotions, comprise a stable and homogeneous suspension, in water, of water-insoluble particulates, and which further comprise at least one anionic surfactant, at least one nonionic or amphoteric cosurfactant and at least one electrolyte, these surfactants being present in such amounts as to impart pseudoplasticity thereto with a yield point of at least 0.2 Pa and constituting spherulites suspended within a lamellar phase.
Claims15
A pseudoplastic free-flowing cosmetic composition comprising a stable and homogeneous suspension in water of water-insoluble particulates;
- the anionic surfactant sodium lauryl ether sulfate, a nonionic or amphoteric cosurfactant selected from the group consisting of a sucroglyceride, an ethoxylated fatty acid alcohol, a betaine, a sultaine, and an imadazoline compound;
- and an electrolyte;
- wherein said surfactant and cosurfactant are present in such amounts as to impart pseudoplasticity thereto with a yield point of at least 0.2 Pa and constituting spherulites suspended within a lamellar phase, and further wherein the suspension is in water devoid of organic solvent.
A pseudoplastic free-flowing cosmetic composition comprising a stable and homogeneous suspension in water of water-insoluble emulsified droplets of oil, the anionic surfactant sodium lauryl ether sulfate, a nonionic or amphoteric cosurfactant selected from the group consisting of a sucroglyceride, an ethoxylated fatty acid alcohol, a betaine, a sultaine, and an imadazoline compound;
- and an electrolyte;
- wherein said surfactant and cosurfactant are present in such amounts as to impart pseudoplasticity thereto with a yield point of at least 0.2 Pa and constituting spherulites suspended within a lamellar phase, and further wherein the suspension is in water devoid of organic solvent.
