Description

Composition for caring keratin materials and dressing film containing the same

Technical Field

The present invention relates to a composition for caring for keratin materials and a dressing containing the same. The invention also relates to a non-therapeutic method for caring for keratin materials.

Background

Dressing films formed from a towel material (such as a nonwoven fabric sheet) impregnated with a cosmetic liquid or the like have been used for cosmetic treatment of skin, particularly the face.

Application films are popular with many consumers because the consumer can place the film on the face for a period of time and then remove the film without massaging the face during application.

It is also known to use active ingredients in cosmetic products to care skin, such as cleansing, moisturizing, shrinking pores, and the like.

Some clay dressing formulations contain hydroxy acids and nicotinamide for anti-acne/oil control and anti-blemish. Hydroxy acids can result in a lower pH formulation while destabilizing the formulation, such as water will seep from the surface and the color will change.

Thus, there is a need for a clay dressing for caring for the skin, wherein the lotion comprising a hydroxy acid is stable.

Disclosure of Invention

i) Magnesium aluminum silicate;

ii) at least one hydroxy acid;

iii) At least one pH adjustor;

iv) at least one chelating agent, and

V) at least one phenolic antioxidant.

The composition has been found to be stable over time.

In the present application, "stable" means that the composition has a significant change in pH, appearance and viscosity for at least two months.

The composition according to the invention can be used for caring skin.

According to a second aspect, the present invention provides a dressing for care of keratin materials, comprising:

A) A water-insoluble dressing film towel material, and

B) The composition according to the invention impregnated into the dressing towel.

According to a third aspect, the present invention provides a non-therapeutic method for treating keratin materials, comprising the steps of:

(i) Applying a composition or dressing according to the invention to keratin materials;

(ii) Allowing the composition or film to rest on the keratin materials for a period of time, and

(Iii) The composition or dressing is removed from the keratin materials.

Other aspects and advantages of the present invention will become apparent upon reading the following description and examples.
