Abstract
Dermatological compositions containing, in a physiologically acceptable medium, at least one retinoid, dispersed benzoyl peroxide and at least one gelling agent of the family of the carrageenans, are useful for treating dermatological conditions and afflictions linked to disorders of cell differentiation and/or proliferation and/or keratinization, notably for treating acne vulgaris.
Claims46
A topically applicable dermatological composition suited for treating acne, said composition comprising thus effective amounts of at least one retinoid and dispersed benzoyl peroxide, at least one iota carrageenan gelling agent, and at least one cation selected from the group consisting of potassium cations and calcium cations, formulated together in the same topically applicable, physiologically acceptable medium therefor, said composition being chemically, physically and rheologically stable for three months at ambient temperature.
A topically applicable dermatological composition suited for treating acne, said composition comprising thus effective amounts of at least one retinoid and dispersed benzoyl peroxide, from 0.1% to 20% by weight of at least one iota carrageenan gelling agent, and from 0.001% to 10% by weight of cations, the cations being selected from the group consisting of potassium cations and calcium cations, formulated together in the same topically applicable, physiologically acceptable medium therefor, the percents by weight being relative to the total weight of the composition, said composition being chemically, physically and rheologically stable for three months at ambient temperature.
A topically applicable dermatological composition suited for treating acne, said composition comprising from 0.01% to 0.5% by weight of adapalene, from 1% to 7% by weight of dispersed benzoyl peroxide, from 0.1% to 10% by weight of at least one iota carrageenan gelling agent and from 0.001% to 8% by weight of cations, the cations being selected from the group consisting of potassium cations and calcium cations, formulated together in the same topically applicable, physiologically acceptable medium therefor, the percents by weight being relative to the total weight of the composition, said composition being chemically, physically and rheologically stable for three months at ambient temperature.
