Description

TECHNICAL FIELD [0001] The present invention relates to an organic-inorganic hybrid material using zinc oxide inorganic powder, a cosmetic composition containing the same, and a method for producing the same. [0002]

The present invention relates to an organic-inorganic hybrid material, a cosmetic composition containing the same and a process for producing the same.

Recently, studies on the harmfulness of the UV A region have been actively conducted, and the regulation of the PA labeling as the UVA blocking index has been implemented in PA +++ from PA ++++ in January 2013, and in Korea and China in December 2016. Generally, UVA refers to light of 320 to 400 nm, and it is known that the wavelength reaches to the dermal layer because the wavelength is long and the energy is low but the material has high permeability. Taichi , M et al. Fragrance Journal, 43, p31, 2015. Studies on the transmission of UVA wavelengths through glass windows have been carried out.

Some organic UV and inorganic sunscreens can be used as raw materials to prevent UVA. However, there are disadvantages such as problems of precipitation in the case of organic sunscreen agents, problems of deterioration with time due to photoactivity, and possibility of causing contact dermatitis in sensitive skin.

Korean Patent Publication No. 2012-0049077 discloses a hybrid titanium dioxide and a cosmetic composition for ultraviolet ray shielding comprising the same as an example of an inorganic sunscreen agent. The above-mentioned cosmetic composition is based on titanium dioxide. Since titanium dioxide (titanium dioxide) causes white coloring (whitening) when it is used for cosmetic applications due to a high refractive index which scatters not only ultraviolet ray but also visible light, blending amount is 25% And has been used as an adjunct to ultraviolet absorbers.

On the other hand, zinc oxide has less opacity than TiO ₂ and covers UVA and UVB regions. However, it has a photocatalytic activity due to ultraviolet absorption and forms oxygen or oxygen radicals, which may cause degradation of organic substances contained in the ultraviolet screening agent and may act as a catalyst capable of damaging DNA. In particular, the present invention is applied to an oil-in-water type formulation, and the above-mentioned active action causes a phenomenon of impairing the stability of the formulation, resulting in a restriction in use. Therefore, there is a need for a sunscreen in which the photocatalytic properties of zinc oxide inorganic powders are reduced or mitigated.

1. Manufacturing Example

1.1. Organic-inorganic composite production

500 g of distilled water was added to a round flask reactor equipped with a condenser, and the resultant was mounted on an ultrasonic bath. Then, 50 g of zinc oxide was added slowly at a dissolver speed of 3000 rpm and treated for 30 minutes for primary dispersion. Then, the ultrasonic energy and the dissolve are immediately further treated for 30 minutes to prepare a monodispersed zinc oxide slurry.

Subsequently, 20 g of monoglouroacetic acid was added thereto at a rate of 10 ml / min under the above-described dispersion conditions, and the mixture was reacted at 90 DEG C for 10 hours. Thereafter, the reaction solution is cooled to room temperature, filtered, and then washed with distilled water and ethanol to obtain a carboxylated zinc oxide filter cake in which the reaction cake pH is controlled to be neutral.

Then, the filter cake was dispersed in 500 g of a 50 wt% ethanol aqueous solution adjusted to pH 3.2 with sulfuric acid in a round flask reactor equipped with a condenser at a dissolver speed of 3,000 revolutions. 2.0 g of dimethylhydroxymethylpolysiloxane was dissolved in 10 g of ethanol, and the mixture was reacted at 90 DEG C for 5 hours. Thereafter, the filter cake was washed with distilled water and ethanol to obtain a filter cake having neutral pH of the reaction cake, and dried at 100 ° C to obtain 53.4 g of dimethylmethylpolysiloxane ester zinc oxide.
