- the invention relates to an aqueous dispersion of multiphase particles of polymers, and to its use in film-forming compositions that may for example be applied to skin, mucous membranes, wounds, lesions and / or skin disorders.
- the invention also relates to the use of said dispersions to form physiologically acceptable films that can be applied to the skin.
- Physiologically acceptable formulations comprising latex type film forming compositions (aqueous polymer dispersions) are well known to those skilled in the art.
- compositions for use as a shaving foam comprises one or more film-forming materials dispersed in an aqueous phase by surfactants.
- the film-forming materials may be polymers such as polyvinylpyrrolidone or hydroxyethylcellulose or copolymers such as a styrene-acrylate or styrene-butadiene latex.
- surfactants are described such as in particular sarcosinic acid derivatives and more particularly sodium W-myristoylsarcosinate.
- the compositions according to this document are shaving foams and in particular do not make it possible to form an isolatable film which is elastic, water-resistant, which has good breaking strength and durably protects surfaces such as, for example, the skin.
- Latex may in particular be used to form isolable films.
- 3M discloses a latex composition comprising an aqueous copolymer dispersion comprising:
- a "soft" monomer whose homopolymer corresponds to a Tg of less than -15 ° C., such as butyl acrylate,
- a "hard” monomer whose homopolymer corresponds to a Tg greater than -5 ° C., such as methylmethacrylate, and
- composition also comprising iodine for its antimicrobial properties and for stabilizing the aqueous dispersion as well as a surfactant to help disperse the latex particles in the aqueous phase.
- iodine such as N-vinylpyrrolidinone
- This film-forming composition is intended to form a protective film on the skin, such as in particular a dressing.
- films formed using these compositions have limited mechanical properties, especially in terms of elasticity and breaking strength.
- the invention thus has, according to a first aspect of the invention, an aqueous dispersion of multiphase particles of polymers in which the polymer particles comprise at least two distinct phases:
- the invention also relates to a film-forming composition
- a film-forming composition comprising, in a physiologically acceptable medium, an aqueous dispersion of multiphase particles of polymers.
- the invention also relates, according to a 3 rd aspect, a film having at least two different Tg, said film comprising multiphase polymer particles and a surfactant, wherein the polymer particles comprise at least two distinct phases:
- said surfactant is selected from amino acid derivatives and wherein the polymer Pi is formed by polymerization in the presence of a crosslinking agent.
- the subject of the invention is the use of the film previously described, for protecting skin surfaces, mucous membranes, wounds, lesions and / or skin conditions.
- the present invention relates to an aqueous dispersion of multiphase particles of polymers.
- aqueous dispersion means a suspension of solid particles in a liquid phase comprising at least water.
- the aqueous phase also comprises at least one surfactant chosen from amino acid derivatives, and optionally an oxidation / reduction system and / or a pH regulator and / or one or more pharmaceutical or cosmetic agents and / or one or more physiologically additive additives. acceptable.
- the aqueous phase may especially be present in the dispersion according to the invention in a content ranging from 20 to 75%, preferably from 40 to 70% by weight, relative to the weight of the aqueous dispersion.
- Multiphasic polymer particles may especially be present in the dispersion according to the invention in a content ranging from 20 to 75%, preferably from 40 to 70% by weight, relative to the weight of the aqueous dispersion.
- the multiphase particles of polymers are solid particles of polymers which are dispersed in the aqueous phase.
- polymer is meant, in the sense of the present invention, a homopolymer or a copolymer.
- Said multiphasic particles comprise at least two phases, each phase consisting of a polymer having very distinct properties, such as, in particular, different glass transition temperatures (Tg) for each phase.
- Tg glass transition temperatures
- glass transition temperature (Tg) of each phase of multiphase polymer particles is meant either the Tg of the homopolymer as referenced in the literature, or the Tg of the copolymer calculated by the law of the Fox-Flory blends. Indeed, the Tg of each phase is not directly measurable on the multiphase particles as such.
- a phase of the particle consists of a copolymer
- the skilled person can easily calculate the Tg of this phase using in particular the law of Fox-Flory mixtures.
- Tg glass transition temperature
- AB glass transition temperature of the copolymer
