Description

  The present invention relates to a composition that is preferably in the form of an O / W type, more preferably in the form of an O / W type gel, and even more preferably in the form of an O / W gel emulsion.

  In the skin care field, one challenge is to quickly lighten the skin tone while at the same time achieving a natural finish and a cool skin care application sensation.

  Most commonly, pigments such as titanium dioxide are used to improve skin brightness in skin care products. Usually, optical powders such as pigments, when introduced into skin care products, are not preferred for skin care applications because they thicken the product and also provide a powdery or sticky feel. This difficulty of application also results in a non-uniform distribution of the powder on the skin, leaving a mark or an unnatural finish when applied.

  Thus, there is a need for a composition that can provide a cool application sensation suitable for skin care products and can also lighten the skin while providing a uniform and natural coating.

  The present invention also relates to a cosmetic method for keratin materials, preferably the skin, comprising applying a composition according to the present invention to a keratin material.

  After intensive investigations, the inventors have discovered that it is possible to provide a composition that can provide a cool sensation and uniform coating to the skin.

Therefore, one embodiment of the present invention provides
(a) at least one silicone oil;
(b) at least one hydrophobic particle;
(c) at least one water-soluble or water-dispersible cross-linked or non-cross-linked containing at least acrylamide-2-methylpropane sulfonic acid (AMPS) monomer in a form partially or fully neutralized with sodium hydroxide A polymer,
(d) relates to a composition comprising water.

  The composition according to the invention can provide a refreshing sensation and uniform coating on the skin.

  Since the composition according to the present invention contains water, it can provide a cool sensation. In particular, when the composition according to the invention is of the O / W type, it comprises an external aqueous phase that can provide a cool sensation when applied to the skin, i.e. immediately after contact with the skin.

  Since the composition according to the invention comprises at least one hydrophobic particle, a keratinous material, in particular a substrate such as the skin, can be covered with a thin layer of hydrophobic particles. Hydrophobic particles can also brighten the substrate, especially when the hydrophobic particles are pigments, preferably hydrophobically surface-treated metal oxides, more preferably hydrophobically surface-treated titanium dioxide. The uniform coating provided by the composition according to the invention is useful for achieving a natural finish.

  Since the hydrophobic particles are selectively localized in the silicone oil, they do not interfere with the cool feel provided by the water in the composition according to the present invention. Silicone oil can have good compatibility with the hydrophobic particles, and the hydrophobic particles can be well dispersed in the silicone oil. Therefore, the hydrophobic particles can form a uniform coating and contribute to a natural finish. Silicone oil can also reduce the powdery sensation and stickiness that can be derived from hydrophobic particles.

  By the combination of components (a) to (d) in the composition according to the invention, the composition according to the invention can provide both a nice and cool sensation and a nice and uniform coating.

  In addition, the present invention is stable so as to maintain a uniform state for a long time. For example, when the composition according to the invention is of the O / W type, the composition according to the invention does not cause phase separation between the oil phase and the aqueous phase.

  Hereinafter, the composition according to the present invention will be described in detail.

The organic layer can be deposited on the particles by evaporating the solvent, chemical reaction between the molecules in the amphiphile, or creating covalent bonds between the molecules in the amphiphile and in the particles.

  Thus, surface treatment can be performed, for example, by chemically reacting the amphiphile with the surface of the particle and by creating a covalent bond between the amphiphile and the particle. This method is described inter alia in US Pat. No. 4,578,266.
