Description

[0001] Cosmetics with elastic tension sheet containing cosmetic composition with sunscreen function [0002]

The present invention relates to a cosmetic composition having an ultraviolet shielding function emitted through a elastic net. More specifically, in the present invention, an organic UV blocking agent and an inorganic UV blocking agent are mainly used in order to obtain an excellent UV blocking effect in UV blocking products. However, in the case of elastic network cosmetics, the elasticity net is stretched or twisted The present invention relates to a cosmetic composition for improving the above problems and to a cosmetic product in which such a cosmetic composition is discharged through a elastic net.

Recently, the ozone layer has been destroyed due to environmental pollution and exposure to ultraviolet rays has been intensified. Such ultraviolet rays are a main cause of causing erythema, edema, freckles and skin cancer in the skin. Accordingly, there has recently been a demand for development of a product that protects skin from ultraviolet rays. Especially, as the life becomes more and more, not only the desire to protect the skin from living ultraviolet rays but also the demand for protecting the skin from the ultraviolet rays is increasing as the leisure activity population such as skiing, golf, and bathing water is increased. Research is underway.

In general, ultraviolet rays are divided into three regions according to wavelength, ultraviolet C (UV-C) at a wavelength of 200-290 nm, ultraviolet B (UV-B) at a wavelength of 290-320 nm, The wavelength is classified as ultraviolet A (UV-A). UV-C passes through the ozone layer and disappears without reaching the surface. UV-B penetrates into the epidermis of the skin, causing erythema, freckles and edema. UV-A penetrates the skin's dermis and promotes skin cancer, wrinkles, and melanin formation, leading to skin aging and skin irritation.

Long-wavelength ultraviolet (UV-A) has been identified as the target of the boundary by promoting skin aging by protein denaturation in the dermis, capillary expansion, and destruction of DNA (DNA). On the other hand, the medium-wave ultraviolet (UV-B), which is mostly absorbed in the epidermis of the skin, is called harmful ultraviolet rays because it rapidly acts on the epidermis and burns. The long wavelength ultraviolet rays reach the skin all year round, but because they do not have any subjective symptoms, the skin becomes old without knowing oneself.

As the risk of exposure to sunlight became known, public interest in UV protection products increased, and accordingly, products with various sun protection factor (SPF) and protection grade of UVA (PA) Is being released.

With regard to the formulation of cosmetics, there is a problem that liquid cosmetics are excellent in spreadability and feelings, and have a high preference, but they are inconvenient for use and should not be portable. In order to solve this problem, it was developed as an easy-to-use and portable cosmetic product by discharging the contents through a elastic net such as rubber on a container containing a cosmetic material. Examples of elastic network materials include acrylonitrile-butadiene rubber (NBR) Rubber fluids that are easily elastic are mainly used.

However, there has been a problem that the elastic network of the cosmetic container is deformed or twisted depending on the components of the cosmetic composition used.

For example, in the cosmetic composition according to the present invention, the case where the cosmetic composition contains only an inorganic ultraviolet screening agent as an ultraviolet screening agent and does not contain an organic ultraviolet screening agent may also be included in this term.

In the specification according to the present invention, the term " most contralateral " may refer to a portion where the cosmetic composition has the greatest direct contact surface with the elastic net. For example, when the single phase is composed of a single phase (that is, single phase or single phase), the single phase is referred to as the outermost phase. In the case of the water-in-oil type emulsion, the outermost phase is the oil phase. Is referred to as '(X) / (X) n / Y' (where 'X' and 'Y' may be water phase or oil phase, Y 'is the outermost phase, for example, in the water-in-oil type (O ₁ / W / O ₂ ), the outermost phase is the "oil phase (O ₂₎ '.

The "organic UV blocking agent present in the outermost phase but not causing the deformation of the elastic net" according to the present invention can be realized by selecting the composition of the cosmetic composition and / or composition of the organic UV blocking agent.

More specifically, the effect of the present invention can be achieved by constituting the outermost phase of the cosmetic composition as an oil phase on the phase selection side of the cosmetic composition.

When the outermost phase of the cosmetic composition is water-based, the organic ultraviolet screening agent present in the outermost surface of the water-based phosphor is water-soluble or water-dispersible, or water-soluble or water-dispersible, or water-soluble or water- Lt; / RTI > From the aspect of selecting the composition of the organic ultraviolet screening agent contained in the cosmetic composition, an organic ultraviolet screening agent which does not cause deformation of the elastic net or an organic ultraviolet screening agent which is modified so as not to cause deformation of the elastic net can be used. The term " modifying " encompasses both chemical and physical modifications of the organic sunscreen agent, and includes, for example, methods for preventing direct contact between the organic sunscreen agent and the elastic network present in the outermost surface (such as encapsulation of an organic sunscreen agent) (Eg, deformation of the compound structure, deformation to water-soluble and water-dispersible properties), etc., in which the ultraviolet screening agent and the elastic net contact but do not cause deformation.

In the cosmetic composition according to the present invention, any ultraviolet screening agent may be contained in addition to the outermost ultraviolet screening agent. Any ultraviolet screening agent conventionally used in the art, regardless of the type of ultraviolet screening agent, the dispersibility, and the water . For example, in the multi emulsion, oil in water type (O ₁ / W / O ₂ ) or water in oil type (W / O ₁ / W), 'oil phase (O ₁ )' includes any ultraviolet screening agent Can be used.
