  • Publication number: 20230137524
    Abstract: A cosmetic composition that having an aqueous continuous phase and an oil discontinuous phase dispersed in the aqueous continuous phase. The oil discontinuous phase can have a particle size of from about 0.01 mm to about 20 mm. The oil discontinuous phase can be dispersed for at least 24 hours and the composition can be free of polymeric encapsulation. The cosmetic composition can provide prolonged dispersion of the dispersed oil phases, especially prolonged dispersion of the visible dispersed oil phases without the use of polymeric encapsulation and/or oil-absorbing porous particulates for dispersions.

  • Publication number: 20230137149
    Abstract: A cosmetic product that includes a cosmetic composition. The cosmetic composition can include an aqueous phase and an initial oil phase. The cosmetic composition is contained in a container. The product also includes indicia for a user to shake the container where shaking the composition breaks the initial oil phase into oil discontinuous phases dispersed in the aqueous phase. The oil discontinuous phase can have a particle size of from about 0.1 mm to about 20 mm and the discontinuous phase can be dispersed for at least 24 hours. The cosmetic product can provide prolonged dispersion of the dispersed oil phases.

  • Patent number: 10549129
    Abstract: A cosmetic composition suitable for topical application is provided. The cosmetic composition comprises: glycerin; a lipid bilayer structurant with a glyceryl headgroup; a penetration enhancer; and a skin care active. The penetration enhancer increases the amount of active that enters skin when the composition is topically applied, while the glycerin and lipid bilayer structurant with glyceryl headgroup work together with lipid bilayers of the skin to impede progress of active through the skin.

  • Patent number: 9763864
    Abstract: A cosmetic composition suitable for topical application is provided. The cosmetic composition comprises: a safe and effective amount of a humectant; a safe and effective amount of a lipid bilayer structurant, and a safe and effective amount of a chaotropic agent. The chaotropic agent denatures the cross-linked proteinaceous layer sitting immediately above skin thereby increasing the amount of humectant and lipid bilayer structurant that enters the stratum corneum; the humectant binds together with water molecules and the lipid bilayer structurant knits together the lipid bilayers of the stratum corneum thereby preventing water loss.
