JPS63174912A - Rouge composition - Google Patents

Abstract

PURPOSE:To obtain a rough composition having soft feeling and giving moisture and low irritation to the lip, by using a vegetable oil having a specific iodine value, a specific ultraviolet absorbent and a specific antioxidant as essential components. CONSTITUTION:The objective rouge composition contains 5-25wt.% vegetable oil having an iodine value of 60-180 (e.g. safflower oil, sesame oil, castor oil, etc.), 0.001-3% one or more ultraviolet absorbents of formula I [R is -C(CH3) or -OCH3], formula (R is CnH2n+1; n is 2-10) or formula III (one or two of R1-R3 are group of formula IV and the other is group of formula V) and 0.01-2% antioxidant selected from tocopherols, flavone derivative, gallic acid derivative and extract of Rumex japonicus (a plant of Polygonaceae family). The ultraviolet absorber in the composition acts as an adjuvant of the antioxidant to remarkably suppress the degradation of the vegetable oil. Accordingly, the change in odor and color of rouge and the irritation to the lip can be suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a lipstick composition that is soft to the touch, provides moisture to the lips, and is less irritating to the lips.

[Prior Art] Lipstick is generally composed of oil, wax, and coloring material, and provides a beautiful tone and texture on the lips.

However, on the other hand, consumers are also complaining of dry lips, and it is not uncommon for lipsticks to contain moisturizers or chemicals.

In recent years, lipsticks have been used to prevent sweating and stabilize color and odor.
It contains synthetic ester oil, hydrocarbon oil without double bonds, and even silicone oil, but on the other hand, these oils do not have the same softness on the lips as vegetable oils, and they are mixed with pigments and active agents. When used, it could lead to irritation such as dryness and stinging of the lips.

It is known that a lipstick composition that is less irritating can be obtained by incorporating mild vegetable oils on the lips; however, in the case of vegetable oils,
It oxidizes over time, causing your lipstick to smell bad or change its color.
Furthermore, there have been other problems such as irritation to the lips.

Although vegetable oil is unstable to light and heat as an oil component, since it is a natural product, it contains trace amounts of various vitamins, phospholipids, and amino acids, so it is long-awaited to create a hypoallergenic lipstick. Ta.

[Problems to be solved by the invention] It is already known that antioxidants are added to oil to improve oxidation stability, and ultraviolet absorbers are added to improve photostability; There are also examples of such combinations. However, vegetable oils contain many double bonds, so even if antioxidants are added, it is not possible to completely prevent the oil from deteriorating; when it comes into contact with water or air, the double bonds open, causing saturated compounds to form. As a result, vegetable oils usually lose their natural soothing properties and moisturizing effect on the lips.

[Means for Solving the Problems] As a result of intensive studies to solve these conventional drawbacks, the present inventor has determined that a specific ultraviolet absorber is added to vegetable oil for the purpose of preventing oxidation, rather than for its original purpose of ultraviolet absorption. The inventors completed the present invention by discovering that the deterioration of vegetable oils can be dramatically suppressed by using them as adjuvants. This effect is also exhibited in emulsified lipsticks that contain water in their formulation.

That is, the present invention is a lipstick composition characterized by containing the following three components.

1. One or more kinds selected from vegetable oils having an iodine value of 60 to 180 ■ One or more kinds selected from ultraviolet absorbers represented by general formulas (1), (2) and (3) r11 ．． One or more antioxidants selected from tocopherols, flavone derivatives, gallic acid derivatives, and extract of the Polygonaceae plant Kishigigi (blank below) (1) CH30QCOCH2COQR (R is -C (C

) Co2R (R is CII 1n=2 to 10) n 2n+1 (3) CH20R1 ll0R2 C1120R3 (One or two of R1, R2, and R3 are represented by the following formula A, and the rest are represented by the following formula B) B-COCH(C2H5)C4H9 Hereinafter, the structure of the present invention will be explained in detail.

The vegetable oils used in the present invention are some of semi-drying oils, non-drying oils and drying oils with an iodine value of 60 to 180 extracted from plant seeds. For example, drying oils include safflower oil, soybean oil, sunflower oil, cherry seed oil, and hemp seed oil; semi-drying oils include sesame oil, wheat germ oil, corn oil, rapeseed oil, bran oil, lemon seed oil, and tomato seed oil; Non-drying oils such as cottonseed oil include castor oil, camellia oil, coffee seed oil, olive oil, morning glory seed oil, sasanquat oil, peanut oil, fennel seed oil, and the like.

If the iodine value exceeds 180, no combination of antioxidants and ultraviolet absorbers will be able to suppress the oxidation and deterioration of the vegetable oil, and if it is less than 60, the natural feel of the vegetable oil on the lips will be impaired. Therefore, it is excluded from the present invention.

The ultraviolet absorber used in the present invention is an ultraviolet absorber represented by the above general formula (1) that absorbs ultraviolet rays in the UV-A region of 320 to 400 nm, general formula (2), and general formula (3).
) is an ultraviolet absorber that absorbs ultraviolet light in the tJV-B region of 290 to 320 nm.

The antioxidants used in the present invention include tocopherols (vitamin E) such as α, β, γ, or δ-tocopherol, flavones, flavonols, trioxyisoflavones, flavone derivatives such as quercetin, rutin, gosybetin, and quercitrin, and caffeic acid. , gallic acid, chlorogenic acid, ferulic acid, gallic acid derivatives such as oryzanol, and extracts from the Polygonaceae plant, Kishigigi or similar plants.

Regarding the blending ratio in the composition, vegetable oil accounts for 0.0% of the total amount.
1 to 70% by weight (hereinafter referred to as %), ultraviolet absorber: 0
．． The content of the antioxidant is preferably 0.001 to 5%, more preferably 5 to 25% of the vegetable oil, 0.05 to 1% of the ultraviolet absorber, and 0.01 to 2% of the antioxidant.

The lipstick composition of the present invention contains one or more of the above-mentioned essential ingredients, but in addition, if necessary, various ingredients commonly used in cosmetics may be added to the extent that the effects of the present invention are not impaired. Water, aqueous ingredients, powder ingredients, oil, surfactants, humectants, thickeners, preservatives, fragrances, coloring materials,
It is possible to mix drugs and the like.

The present invention can also be applied to cosmetics other than lipstick compositions, such as makeup products such as foundations, eye shadows and blushers, and external skin preparations such as creams and emulsions.

[Effects of the Invention] The lipstick composition of the present invention maintains the gentle feel on the lips of vegetable oil with an iodine value of 60 to 180 over time due to the synergistic action of a specific antioxidant and ultraviolet absorber that are simultaneously blended. It is an extremely mild cosmetic that does not cause odor or discoloration.

Table (1) shows the studied formulations, and Figure (1) shows the synergistic effect of antioxidants and ultraviolet absorbers on the stability of vegetable oil (safflower oil with an iodine value of 145). In addition, Figure-(1
) is the result of measuring the peroxide value (p, o, v, ) of vegetable oil in an open state at 40°C for 80 days.

Tables (2) and (3) show the formulations of lipsticks containing these ingredients and their physical properties.

It can be seen that the lipstick containing vegetable oil, antioxidant, and ultraviolet absorber has no odor or discoloration, is very stable, maintains the soft application feeling inherent to vegetable oil, and is extremely non-irritating.
