Description

[Technical Field]

[0001] The present invention relates to compositions, in particular sun care compositions, for keratinous materials such as the skin, comprising vitamin B3 and its derivatives. [Background technology]

[0002] Sun care products are widely used to protect keratinous materials, especially skin, from the damage caused by UV radiation.To achieve photoprotection, two types of cosmetic sunscreen active ingredients are typically used: inorganic UV filter and organic UV filter.When inorganic UV filter is used, it is effective to blend it with a large amount of polar oil to adjust UV protection effect and feeling of use.

[0003] For example, WO2022 / 000053 discloses a cosmetic sunscreen composition having high SPF, anti-wrinkle and anti-blemish efficacy, which comprises: (a) 5.0 to 20.0% by weight, based on the total weight of the composition, of at least one UV screening agent selected from octocrylene, terephthalylidene dicamphorsulfonic acid, butyl methoxydibenzoylmethane, drometrizole trisiloxane, ethylhexyl triazone, and mixtures thereof; (b) 0.1 to 10.0% by weight, based on the total weight of the composition, of hydrolyzed hydroxybenzoylmethane; Disclosed is a composition comprising: (a) at least one active compound selected from hydroxypropyl methylcellulose, ...

[0004] Furthermore, WO2011 / 061864 discloses a cosmetic or dermatological composition in the form of an emulsion, which contains a) one or more lipophilic cosmetic or dermatological active ingredients in an amount of at least 5% by mass relative to the total amount of the composition, b) a non-alcoholic volatile solvent different from cyclomethicone, c) a volatile alcohol, d) wax particles, and e) at least one non-volatile compound having a hydrophilic functional group, and which contains an aqueous phase and an oily phase.

[0005] Furthermore, WO2017 / 056506 discloses an oil-in-water emulsified cosmetic composition comprising a solid oil and / or semi-solid oil, a powder, and an emulsifier, wherein the solid oil and / or semi-solid oil is selected from hydrocarbon oils, silicone oils, and ester oils, and has a viscosity of 1500 mPa or less at 25°C, the amount of the blend is 2 to 25% by mass relative to the total amount of the oily phase, and the amount of the oily phase is 40% by mass or less relative to the total amount of the cosmetic composition.

[0006] However, the use of a large amount of polar oil in a cosmetic composition generally requires a large amount of preservative, which can cause skin irritation. Therefore, there is a need for a composition that contains a large amount of polar oil but does not require a large amount of preservative. [Prior art documents] [Patent documents]

[0246] [Table 1]

[0247] [Table 2]

[0248] [evaluation] (Description of antibacterial efficacy testing protocol) The effectiveness of the compositions according to Examples 1 to 5 and Comparative Examples 1 to 4 was evaluated using a challenge test that allowed the determination of the antimicrobial protection level of the composition. The test consisted of artificial contamination of the product tested with various microorganisms (bacteria, yeasts and molds) and monitoring the number of viable pathogens over time. A well-protected product must allow decontamination of foreign microorganisms and must be decontaminated more or less quickly depending on the microbial strain, the type of product and the packaged goods.

[0249] Each composition was dispensed into a number of vials equivalent to the number of microbial species tested. A calibrated suspension of microorganisms was introduced into each of these vials. The microorganisms included bacteria (Enterococcus faecalis), yeast (Candida albicans), and mold (Aspergillus brasiliensis). Seven days after contact between the composition and the pathogens, samples were taken from the vials. The samples were then diluted and plated on Petri dishes, and the number of pathogens was counted. The kinetics (growth or decline) of a given pathogen at a given time was then expressed as a log reduction value. Antimicrobial efficacy was evaluated based on CFU / g values. Good: CFU / g was less than 200 Normal: CFU / g is more than 200 and 1.0 x 10, which is still usable as a cosmetic product. 5 was less than Bad: CFU / g is 1.0 x 10 5 That was all

[0250] The results are shown in Table 3 below.

[0251] [Table 3]

[0252] (sensory evaluation) Four expert panelists evaluated the sensory aspects of "spreadability" and "stickiness" of each composition according to Example 2 and Comparative Examples 5 and 6 by applying 0.1 mL of each sample to their skin. The samples were scored according to the following criteria, and the scores were then averaged. 3: Good 2: Bad 1: Extremely poor

[0253] The results are summarized in Table 4 below.

[0254] [Table 4]

[0255] As can be seen from the evaluation results in Table 3, the compositions according to the examples, which contain a large amount of (a) polar oil, exhibited improved preservative properties. On the other hand, the compositions according to the comparative examples 1 to 4, which do not contain the specific combination of (c) preservative and (d) a compound selected from vitamin B3 and its derivatives, did not exhibit sufficient preservative effectiveness for practical use.

[0256] Furthermore, as can be seen from the evaluation results in Table 4, the composition according to Example 2 showed a higher average score in the sensory evaluation than the compositions according to Comparative Examples 5 and 6, which did not contain a sufficient amount of (a) polar oil. Therefore, the composition according to the present invention showed improved texture and applicability.

[0257] Therefore, it can be concluded that the composition according to the present invention is highly suitable as a cosmetic composition for keratinous materials such as skin, particularly as a sun care cosmetic composition, since it has sufficient storage stability and does not have the problem of skin irritation caused by a large amount of preservatives, while maintaining improved texture and applicability.
