Description

Title of the invention: SUN CARE COMPOSITION technical field

[0001] The present invention relates to a composition, in particular a sun care composition comprising vitamin B3 and its derivatives, for a keratinous substance such as skin. STATE OF THE ART

[0002] Sun care products are commonly used to protect keratinous substances, particularly the skin, from damage caused by UV radiation. There are generally two types of active ingredients in cosmetic sunscreens used to achieve photoprotection, namely inorganic UV filters and organic UV filters. When using inorganic UV filters, it is effective to mix in a large quantity of polar oils to adjust the UV protection effect and the sensation during use.

[0003] For example, WO 2022 / 000053 discloses a cosmetic sunscreen composition with a high SPF, high anti-wrinkle and anti-spot efficacy comprising: (a) 5.0 to 20.0% by weight, relative to the total weight of the composition, of at least one UV filter selected from octocrylene, terephthalylidene diamphrulfonic acid, butyl methoxydibenzoylmethane, drometrizole trisiloxane, ethylhexyl triazone, and mixtures thereof; (b) 0.1 to 10.0% by weight, relative to the total weight of the composition, of at least one active compound selected from hydrolyzed hyaluronic acid, capryloyl salicylic acid, phenylethyl resorcinol, ferulic acid, niacinamide, and mixtures thereof;and (c) 1.5 to 5.0% by weight, relative to the total weight of the composition, of at least one polymer selected from xanthan gum, aluminum starch octenylsuccinate, ammonium polyacryloyldimethyltaurate, a C10-30 alkyl polyacrylate, and mixtures thereof.

[0004] In addition, WO 2011 / 061864 discloses a cosmetic or dermatological composition in the form of an emulsion, containing an aqueous phase and an oily phase, in which the composition comprises: a) at least 5% by weight of one or more lipophilic cosmetic or dermatological active substances relative to the total quantity of the composition; b) a non-alcoholic volatile solvent that is other than cyclomethicone; c) a volatile alcohol; d) wax particles; and e) a non-volatile compound having at least one hydrophilic functional group.

[0005] In addition, WO 2017 / 056506 discloses an oil-in-water emulsified cosmetic composition comprising a solid oil and / or a semi-solid oil, a powder, and an emulsifier, wherein the solid oil and / or the semi-solid oil are selected from a hydrocarbon oil, a silicone oil and an ester oil, its viscosity is less than or equal to 1,500 mPa s at 25 °C, and the amount of formulation is 2 to 25% by mass relative to the total amount of the oil phase; and the amount of the oil phase is less than or equal to 40% by mass relative to the total amount of the cosmetic composition.

[0006] However, when a large quantity of polar oils is used in cosmetic compositions, a problem arises whereby a large quantity of preservatives is also generally required, which can cause skin irritation. Therefore, there is a demand for compositions that do not require large quantities of preservatives, while still including a large quantity of polar oils. DISCLOSURE OF THE INVENTION

[0007] An objective of the present invention is to provide compositions, preferably cosmetic compositions for keratinous substances, such as skin, which have sufficient preservation efficacy so that they do not require large quantities of preservatives, even if they include a large quantity of polar oils.

[0028] After extensive research, the inventors made an astonishing discovery that the chosen compound from vitamin B3 and derivatives thereof can enhance a preservation property of preservatives, and thus made an astonishing discovery that even if the preservative content is low, a sufficient preservative effect can be effectively obtained, and thus finalized the invention.

[0030] Since the composition according to the present invention has improved preservation efficacy, such as antimicrobial activity, it has sufficient storage properties. Furthermore, since the amount of preservatives in the composition can be reduced, the problem of skin irritation due to a large amount of preservatives can be avoided. In addition, since the composition according to the present invention can include a large amount of polar oils with inorganic UV filters, good sensory properties, such as spreadability during application and a non-sticky feel, can be obtained.

[0031] Thus, the composition according to the present invention is very well suited to topical cosmetic compositions for keratinous substances, such as skin.

[0032] The composition and cosmetic process according to the present invention will be explained in more detail below. [Composition]

[0033] The composition according to the present invention may be a cosmetic composition, preferably a cosmetic composition for a keratinous substance, such as skin, and more preferably a sun care composition for a keratinous substance, such as skin.

Among the oils that can be used in the present invention are: volatile or non-volatile oils; these oils may be hydrocarbon oils, in particular of animal or vegetable origin, synthetic oils, silicone oils, fluorinated oils, or mixtures thereof.

[0039] For the purposes of the present invention, the expression "silicone oil" means an oil comprising at least one silicon atom and in particular, at least one Si-O group.

[0040] The expression "hydrocarbon oil" refers to an oil containing essentially hydrogen and carbon atoms and optionally oxygen, nitrogen, sulfur and / or phosphorus atoms.

In particular, the expression "polar oil" designates an oil in which the chemical structure is essentially formed of, or even consists of, carbon and hydrogen atoms, and comprising at least one highly electronegative heteroatom such as an oxygen, nitrogen, silicon or phosphorus atom.

[0042] The definition of Hansen's three-dimensional solubility parameters is described in the article by CM Hansen: "The three dimensional solubility parameters", J. Paint Technol. 39, 105 (1967).

[0043] According to Hansen's space:

[0044] - ôD characterizes the London dispersion forces derived from the formation of induced dipoles during molecular impacts;

[0045] - ôp characterizes the Debye interaction forces between permanent dipoles as well as Keesom interaction forces between induced dipoles and permanent dipoles;

[0046] - ôh characterizes specific interaction forces (such as hydrogen bonds, acid / base, donor / acceptor, etc.);

[0047] - ôa is determined by the equation:

[0048] [Mathematical] ôa = (ôp2 + 0112)½

[0049] The parameters ôp, ôh, ôDet ôas are expressed in (MPa)' / 2, a unit equivalent to (J / cm3)' / 2.

[0050] The Hansen solubility parameters are calculated using HSPiP software version V4.1 on the basis of a chemical structure; the process selected in the software is Y-MB or Yamamoto-Molecular Break.

The test consists of artificially contaminating the product under test with various microorganisms (bacteria, yeasts, and molds) and monitoring the number of viable organisms over time. A product that is satisfactorily protected should allow for more or less rapid decontamination of the introduced microorganisms, depending on the microbial strains, the type of product, and the packaging material.

[0327] Each composition was dispensed into as many pill bottles as there were species of microorganisms under test. A calibrated suspension of microorganisms was introduced into each of these pill bottles. The microorganisms included a bacterium (Enterococcus faecalis), a yeast (Candida albicans), and a mold (Aspergillus brasiliensis). The sample was taken from the bottles after 7 days of contact between the composition and the microorganism. The sample was then diluted and inoculated into a Petri dish to count the number of microorganisms. The kinetics (growth or decline) of a given microorganism at a given time was then expressed as a logarithmic reduction. Antimicrobial efficacy was assessed based on the CFU / g value.

[0328] Good: the CFU / g was less than 200

[0329] Passable: the CFU / g was greater than 200 and less than 1.0 x 10⁵, which is still possible as a cosmetic product

[0330] Bad: the UFC / g was greater than or equal to 1.0 x 105

[0331] The results are shown in Table 3 below.

[0333] 4 professional panelists assessed the sensory aspects of "capacity "spreadability" and "stickiness" of each of the compositions according to Example 2 and Comparative Examples 5 and 6 by applying 0.1 ml of each of the samples on their skin. The samples were assigned a score based on the following criteria, and the scores were then averaged.

[0334] 3: Good

[0335] 2: Bad

[0336] 1: Very bad

[0337] The results are summarized in Table 4 below.

[0338] [Table 4] Table 4 Comp. 2 Ex Comp. 5 Ex. Comp. 6 Spreading capacity 3 2 1 Stickiness 3 2 1.5

[0339] As can be seen from the evaluation results in Table 3, the compositions according to the examples exhibited improved preservation properties despite including a large quantity of (a) polar oils. In contrast, the composition according to Comparative Examples 1 to 4, which does not include the specific combination of (c) preservative and (d) compound selected from Vitamin B3 and its derivatives, did not demonstrate sufficient preservation efficacy in practice.

[0340] Furthermore, as can be seen from the evaluation results in Table 4, the compositions according to Example 2 exhibited higher average sensory evaluation scores compared to the compositions according to Comparative Examples 5 and 6, which do not include a sufficient quantity of (a) polar oils. Thus, the composition according to the present invention exhibited improved texture and application properties.

[0341] Thus, it can be concluded that the composition according to the present invention is very well suited as a cosmetic composition, in particular as a sun care cosmetic composition, for keratinous substances, such as skin, because it has sufficient storage properties without the problem of skin irritation caused by a large amount of preservatives, while maintaining an improved texture and application property.
