Estimating the term…
Cosmetic or dermatological compositions comprising an oil-in-water type emulsion containing oily globules which are coated with a lamellar liquid crystal coating and are dispersed in an aqueous phase, in which each oily globule contains at least one lipophilic compound which is cosmetically or dermatologically active and is individually coated with a monolamellar or oligolamellar layer of at least one lipophilic surface-active agent, at least one hydrophilic surface-active agent, and at least one fatty acid, the coated oily globules having a mean diameter of less than 500 nanometers, preferably less than 200 nanometers, and the oily phase contains a basic agent in the dissolved state, exhibit good skin and hair penetration.
A cosmetic or dermatological composition, comprising an oil-in-water emulsion comprising oily globules which are each coated with a lamellar liquid crystal coating and are dispersed in an aqueous phase, each oil globule comprising at least one lipophilic compound which is cosmetically or dermatologically active and is individually coated with a monolamellar or oligolamellar layer of a mixture of at least one lipophilic surface active agent, at least one hydrophilic surface-active agent, and at least one fatty acid, said coated oil globules having a mean diameter of less than 500 nanometers, and said aqueous phase comprising a basic agent in the dissolved state, wherein said lipophilic surface-active agent, said hydrophilic surface-active agent, and said fatty acid are present in a combined amount of between 2 and 6% by weight based on the total weight of said composition.
An oil-in-water emulsion which comprises oily globules each coated with a coating of lamellar liquid crystal and dispersed in an aqueous phase, wherein each oil globule is individually coated with a monolamellar or oligolamellar layer of a mixture of at least one lipophilic surface-active agent, at least one hydrophilic surface-active agent and at least one fatty acid, the coated globules have a mean diameter of less than 500 nanometers and the aqueous phase contains a basic agent in a dissolved state, wherein said lipophilic surface-active agent, said hydrophilic surface-active agent, and said fatty acid are present in a combined amount of between 2 and 6% by weight based on the total weight of said composition.
A method of treating skin, comprising applying to skin a composition comprising an oil-in-water emulsion comprising oily globules which are each coated with a lamellar liquid crystal coating and are dispersed in an aqueous phase, each oily globule comprising at least one lipophilic compound which is cosmetically or dermatologically active and is individually coated with a monolamellar or oligolamellar layer of a mixture of at last one lipophilic surface-active agent, at least one hydrophilic surface-active agent, and at least one fatty acid, said coated oily globules having a mean diameter of less than 500 nanometers, and said aqueous phase comprising a basic agent in the dissolved state, wherein said lipophilic surface active agent, said hydrophilic surface-active agent, and said fatty acid are present in a combined amount of between 2 and 6% by weight based on the total weight of said composition.
A method of treating hair, comprising applying to hair a composition comprising an oil-in-water emulsion comprising oily globules which are each coated with a lamellar liquid crystal coating and are dispersed in a aqueous phase, each oily globule comprising at least one lipophilic compound which is cosmetically or dermatologically active and is individually coated with a monolamellar or oligolamellar layer of a mixture of at least one lipophilic surface-active agent, at least one hydrophilic surface-active agent, and at least one fatty acid, said coated oily globules having a mean diameter of less than 500 nanometers, and said aqueous phase comprising a basic agent in the dissolved state, wherein said lipophilic surface-active agent, said hydrophilic surface-active agent, and said fatty acid are present in a combined amount of between 2 and 6% by weight based on the total weight of said composition.
