Abstract
The present invention relates to a two-part cosmetic product that imparts a filling and/or swelling effect to hair, eyebrows or eyelashes, preferably a mascara. The invention uses an anhydrous base coat composition with a water absorbing ingredient being a salt of acrylic or polyacrylic acid and a CO2 releasing compound which is a carbonate or bicarbonate to expand or swell the film former of the top coat with the in situ generated CO2 when the water containing top coat is applied to the anhydrous base coat.
Claims10
A two-part cosmetic product for sequential application to hair fibers of the scalp, eyebrows or eyelashes to impart a swelling effect consisting of an anhydrous base coat composition and a top coat wherein
- a) the anhydrous base coat composition consists of:
- i.) at least one water absorbent compound which is a cosmetically acceptable salt of acrylic or polyacrylic acid,
- ii.) a CO2 releasing compound which is an inorganic or organic carbonate, or bicarbonate,
- iii.) a solvent for the water absorbent compound and the CO2 releasing compound,
- iv.) a wax
- v.) auxiliary substances which do not encompass surfactants and
- vi.) optionally, a second water absorbent compound selected from the group consisting of cellulose gum, polysaccharides, natural gums, clays, aluminum silicate, bentonite, aluminum starch octenylsuccinate, acrylic acid, and polyacrylic acid;
- wherein the solvent is dimethiconol in cyclomethicone silicone oil and does not allow an interaction of the salt of acrylic or polyacrylic acid and CO2 releasing compound before the top coat is applied to the base coat composition and wherein the salt of acrylic or polyacrylic acid and the CO2 releasing compound are present in an amount effective to interact and generate CO2 when the top coat is applied, wherein the amount of the salt of acrylic or polyacrylic acid is 15-35% by weight and the amount of the CO2 releasing compound is 10-80% by weight, the weight % being based on the total weight of the base coat composition, and wherein
- b) the topcoat consists of a film former and water with a viscosity that is smaller than that of the base coat composition and the film former is present in the top coat in an amount effective to form a film on the hair fibers and to be expanded by CO2 after application to the base coat composition.
A kit comprising a single two chambered container or two separate containers with a two-part cosmetic product for sequential application to hair fibers of the scalp, eyebrows or eyelashes to impart a swelling effect consisting of an anhydrous base coat composition and a topcoat, wherein the first container or first chamber consists of the anhydrous base coat composition and the second container or second chamber consists of the topcoat, wherein
- a) the anhydrous base coat composition consists of:
- i.) at least one water absorbent compound which is a cosmetically acceptable salt of acrylic or polyacrylic acid,
- ii.) a CO2 releasing compound which is an inorganic or organic carbonate, or bicarbonate,
- iii.) a solvent for the water absorbent compound and the CO2 releasing compound,
- iv.) a wax
- v.) auxiliary substances which do not encompass surfactants and
- vi.) optionally, a second water absorbent compound selected from the group consisting of cellulose gum, polysaccharides, natural gums, clays, aluminum silicate, bentonite, aluminum starch octenylsuccinate, acrylic acid, and polyacrylic acid;
- wherein the solvent is dimethiconol in cyclomethicone silicone oil and does not allow an interaction of the salt of acrylic or polyacrylic acid and CO2 releasing compound before the top coat is applied to the base coat composition and wherein the salt of acrylic or polyacrylic acid and the CO2 releasing compound are present in an amount effective to interact and generate CO2 when the top coat is applied, wherein the amount of the salt of acrylic or polyacrylic acid is 15-35% by weight and the amount of the CO2 releasing compound is 10-80% by weight, the weight % being based on the total weight of the base coat composition, and wherein
- b) the topcoat consists of a film former and water with a viscosity that is smaller than that of the base coat composition and the film former is present in the top coat in an amount effective to form a film on the hair fibers and to be expanded by CO2 after application to the base coat composition.
