Problems solved by technology

Also, the sunscreen stick type does not contain water or contains a small amount of water, so there is a problem that it cannot give a refreshing feeling when applied to the skin in summer
[0004] Among the types of cosmetics, light and refreshing formulations include gels, sprays, and toners. However, due to the characteristics of light formulations, it is difficult to maintain the formulation and contain a sufficient amount of UV protection agent.
Also, when a thickener is added to a water-soluble UV protection agent, dehydration occurs, resulting in a decrease in the viscosity of the dosage form, so there is a gel type that is difficult to realize a water-dispersed dosage form that contains a large amount of water and is easy to reapply frequently viscosity problem

preparation example

[0045] Preparation example: the preparation of embodiment and comparative example

[0046] A water dispersion type cosmetic composition for UV protection was prepared using the ingredients described in Table 1 below. Examples 1 to 5 are cosmetic compositions for UV protection in which the ratio of different thickeners is changed, Comparative Example 1 is a cosmetic composition for UV protection without adding a second thickener, Comparative Examples 2 to 4 In order to change the anti-ultraviolet cosmetic composition of the kind of the second thickener, comparative example 5 is the cosmetic composition for anti-ultraviolet without adding the first thickener, and comparative example 6 and comparative example 7 are to change the anti-ultraviolet agent and thickener The cosmetic composition for ultraviolet protection of the ratio of a tackifier, the comparative example 8 is the cosmetic composition for ultraviolet protection which changed the kind of the 1st thickener.

experiment example 1

[0052] Experimental example 1: Observation of dosage form and transparency and viscosity evaluation

[0053] Table 2 shows the results of observing the dosage form formation degree and transparency of the composition of the said Example and the comparative example, and measuring the viscosity. Viscosity was measured using a Brookfield Viscosmeter LVT (Brookfield Viscosmeter LVT) with a No. 4 spindle and a rotation speed of 6 rpm.

[0055]

[0056]

[0057] As can be seen in Table 2 above, Examples 1 to 5 have viscosities of about 45,000 to 80,000 cP, and form transparent and stable gel dosage forms. Representatively, the shape of the dosage form of the composition of Example 1 is shown in figure 1 middle. refer to figure 1 , it can be confirmed that the transparent content does not flow and maintains the gel form stably.

[0058] On the contrary, it can be confirmed that in Comparative Example 1 where the second thickener was not added, it was dif...

experiment example 2

[0061] Experimental example 2: Evaluation of usability

[0062] In order to understand the feeling of use of the compositions of the above-mentioned examples and comparative examples, 30 women in their 20s to 40s were evaluated on the items of initial moisturizing feeling, adhesion speed, sticky feeling after drying, and soft feeling after drying, and the results are shown. in Table 3 below.

[0063] The experimental method is as follows: extract the samples of the above-mentioned examples and comparative examples respectively at 1 mg / cm 2 , with a width of 3 cm in width and 2 cm in length, apply it on the inside of the arm of the tester according to the usual makeup habits, and use the feeling as the evaluation scale in the evaluation item, and evaluate it in 5 stages. The score is a full score of 5 points. According to the stage, take 1 point for unit rating. The feeling of use was calculated as the average value of the scores of 10 people, and the values ​​excluding dev...

Abstract

The present invention relates to an ultraviolet-proof cosmetic composition in a water-dispersible form containing a heterogeneous organic tackifier, and relates to an ultraviolet-proof cosmetic composition in a water-dispersible form that can be frequently re-applied while providing a cool feeling and a refreshing feeling in use due to the inclusion of a large amount of water. The ultraviolet-proof cosmetic composition is characterized by comprising: a water-soluble ultraviolet-proof agent; and a heterogeneous organic tackifier comprising a first tackifier and a second tackifier, the ultraviolet-proof cosmetic composition being a water dispersible formulation.

Description

technical field [0001] The present invention relates to a water-dispersion-type cosmetic composition for UV protection containing a different organic thickener, and to a water-dispersion-type water-dispersion type that can be frequently reapplied while providing a cool feeling and a refreshing feeling of use because it contains a large amount of water. Cosmetic composition for UV protection. Background technique [0002] Recently, consumers have expanded their awareness of the need for UV protection not only in summer or during sports and leisure activities, but also in daily life. UV protection products used for this purpose are only effective for a limited period of time, and reapplication every 2-3 hours is usually recommended. Therefore, there is an increasing demand for UV protection products with a refreshing and light feeling of use. [0003] Generally, anti-ultraviolet products can be prepared in multiple dosage forms such as sunscreen, sunscreen lotion, sunscreen ...
