Abstract
Description
Technical Field
[0001] The present invention relates to a cleansing agent used for the purpose of removing makeup cosmetics on the skin.
Background Art
[0002] Makeup cosmetics such as foundation not only beautify but also have a close-fitting type on the skin that does not cause makeup smudging due to sweat and sebum, and are strongly supported by consumers. That is, as cleansing cosmetics, those makeup cosmetics such as foundation are very difficult to remove, and a strong cleansing power for removing cosmetics is required. However, generally, it is known that the cleansing power of a cleansing agent is inversely proportional to the molecular weight of the cleansing agent, and the smaller the molecular weight, the higher the cleansing power. That is, the cleansing agent aims to remove makeup cosmetics such as foundation and dirt on the skin, but there is an antinomic relationship from the viewpoints of pursuing strong cleansing power and gentleness to the skin.
[0003] Hiba oil is an essential oil obtained by steam distillation from Hiba wood. It contains dozens of components, and approximately 1 kg can be obtained from 100 kg of Hiba wood. The unique scent of Hiba oil is known to have calming and relaxing effects, and various products such as air fresheners and bath additives utilizing the scent of Hiba are sold. In addition, as described in Patent Document 1, Hiba oil is known to have extremely excellent antibacterial properties, and also has various other effects such as insect repellent properties (described in Patent Document 2) and deodorizing properties (described in Patent Document 3). Hiba, the raw material for Hiba oil, refers to both Thujopsis dolabrata SIEBOLD et ZUCCARINI and its variety, Thujopsis dolabrata SIEBOLD et ZUCCARINI var. hondai MAKINO, both belonging to the genus Thujopsis in the family Cupressaceae, and are plants endemic to Japan. Asunaro (Thujopsis dolabrata) is distributed from Aomori Prefecture in the north to Kagoshima Prefecture, while Hinoki Asunaro (Thujopsis cypress) is distributed mainly in Aomori Prefecture, from southern Hokkaido to northern Kanto. The properties of Hiba (Thujopsis dolabrata) are already known, including insecticidal and antibacterial properties, and the properties of Hiba oil are inherited from the Hiba tree from which it is derived. Furthermore, medical research is underway on the effects of hinokitiol, an active ingredient contained in Hiba, including its antitumor effects.
[0004] Essential oils such as cypress oil are used as aromatherapy oils to enjoy their fragrance, and are also added to cosmetics. For example, essential oils are sometimes included in cleansing products used to remove makeup. However, traditionally, the purpose of including essential oils such as cypress oil has been almost exclusively to utilize their fragrance, and they have not been used to directly contribute to the cleansing effect of cleansing products.

[0012] The cleansing agent of this embodiment contains 5 to 20% by weight of cypress oil, an essential oil, as a solvent for makeup cosmetics. To date, there have been no reports whatsoever that cypress oil itself has the effect of enhancing the removal of makeup cosmetics, and this invention represents a novel finding. Furthermore, there have been no reports whatsoever that essential oils themselves, not just cypress oil, have the effect of enhancing the removal of makeup cosmetics. In the cleansing agent of this embodiment, the makeup removal effect is 33 to 53% higher than in the case without cypress oil.
[0013] The Hiba oil according to this embodiment is an essential oil obtained from either Thujopsis dolabrata or its variety, Thujopsis cuspidata, which belong to the genus Thujopsis in the family Cupressaceae, or both, as raw materials. The raw materials may be sourced from any location, but are preferably from Aomori Prefecture, with Thujopsis cuspidata from Aomori Prefecture being the most preferred. The Hiba oil according to this embodiment may be obtained by steam distillation, which is the most common method for extracting essential oils, or by other extraction methods such as pressing, solvent extraction, or CO2 distillation.
[0014] The Hiba oil according to this embodiment contains acidic substances such as tropolones hinokitiol (molecular weight 164.21) and β-thrabuline (molecular weight 162.188), as well as citroneric acid (molecular weight 170.25), carbachlor (molecular weight 150.217), l-rosinic acid (molecular weight 302, etc.). The Hiba oil according to this embodiment contains neutral substances such as thujopsene (molecular weight 204.35), cedrol (molecular weight 222.37), paracymene (molecular weight 134.22), dihydrocymene, and widrol. The weight percentages of each component in the Hiba oil according to this embodiment are 1-2% by weight for hinokitiol, 1-2% by weight for β-thrabuline, 1-2% by weight for citroneric acid, 50-60% for thujopsene, and 5-10% for cedrol.
[0015] The amount of cypress oil according to this embodiment is preferably 5 to 20% of the total weight of the cleansing agent according to this embodiment. More preferably, it is 10% of the total weight of the cleansing agent according to this embodiment. When the amount of cypress oil according to this embodiment is included in the cleansing agent according to this embodiment at a rate of 5 to 20% of the total weight, the weight percentages of each component in the cleansing agent according to this embodiment are as follows: hinokitiol 0.05 to 0.4% by weight, β-thujaplicin 0.05 to 0.4% by weight, citronellic acid 0.05 to 0.4% by weight, thujopsene 2.5 to 12%, and cedrol 0.25 to 2%.
[0016] Regarding the substances other than cypress oil in the cleansing composition according to this embodiment, any base material that constitutes an oil-type cleansing composition may be used, but typical examples include surfactants, ester oils, and hydrocarbon oils.
[0017] Examples of surfactants that can be used in the cleansing agent according to this embodiment include nonionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants, but nonionic surfactants are preferred from the viewpoint of emulsification.Nonionic surfactants that can be used in the cleansing agent according to this embodiment include diglycerin fatty acid esters such as polyglyceryl-2 sesquioleate, polyglyceryl-2 sesquiisostearate, polyglyceryl-2 diisostearate, and polyglyceryl-2 dioleate; triglycerin fatty acid esters such as polyglyceryl-3 coconut oil fatty acid and polyglyceryl-3 triisostearate; tetraglycerin fatty acid esters such as polyglyceryl-4 caprate and polyglyceryl-4 isostearate; and polyglyceryl-6 caprylate.

For example, the ester oil that can be used in the cleansing agent according to the present embodiment can be used in an amount of about 30 to 50% by weight of the total weight of the cleansing agent according to the present embodiment.
[0019] As hydrocarbon oils that can be used in the cleansing agent according to this embodiment, mineral oil, undecane, dodecane, tridecane, liquid paraffin, liquid isoparaffin, squalane, α-olefin oligomer polybutene, petrolatum, etc., any hydrocarbon oils that are commonly used can be used individually or in combination as long as they do not impair the effectiveness of the cleansing agent according to this embodiment. For example, the hydrocarbon oils that can be used in the cleansing agent according to this embodiment can be used in an amount of about 5 to 40% by weight of the total weight of the cleansing agent according to this embodiment. More preferably, the hydrocarbon oils that can be used in the cleansing agent according to this embodiment can be used in an amount of about 25 to 40% by weight of the total weight of the cleansing agent according to this embodiment, such that the sum of the cypress oil and hydrocarbon oils according to this embodiment is about 45% by weight of the total weight. In the cleansing agent according to this embodiment, when hydrocarbon oils are used, the proportion of hydrocarbon oils can be reduced by the amount of cypress oil added during production. The cleansing agent according to this embodiment can reduce the amount of hydrocarbon oil and can also improve the makeup removal power compared to conventional cases that do not use cypress oil. Generally, oil-based cleansers primarily use hydrocarbon oils such as mineral oil (liquid paraffin), which are derived from petroleum. While hydrocarbon oils like mineral oil are known for their high removal power for oily cosmetics, their strong degreasing properties can also strip the skin of essential oils. Therefore, people with skin problems such as dry or sensitive skin tend to prefer oil-based cleansers that do not contain or contain very little hydrocarbon oil such as mineral oil. However, cleansers that do not contain hydrocarbon oils such as mineral oil often have weaker cleansing power and fail to completely remove the oily components of cosmetics. The cleanser according to this embodiment has low skin irritation during and after use and maintains skin health, making it particularly useful for people with skin problems who want to thoroughly remove makeup.
[0020] Regarding substances other than hinoki oil in the cleansing agent according to this embodiment, animal and vegetable oils, silicone oils, higher alcohols, ether oils, etc. may be used. Examples of animal and vegetable oils include olive oil, castor oil, avocado oil, safflower oil, soybean oil, camellia oil, corn oil, rapeseed oil, rice bran oil, palm oil, sunflower oil, cottonseed oil, mink oil, etc. Examples of silicone oils include silicone oils such as dimethylpolysiloxane and dimethicone (chain silicone, cyclic silicone, modified silicone, etc.). Examples of higher alcohols include lauryl alcohol, oleyl alcohol, isostearyl alcohol, etc. Examples of ether oils include alkyl-1,3-dimethylbutyl ether, dicaprylyl ether, dihexyl ether, cetyl-1,3-dimethylbutyl ether, etc.
[0021] Regarding substances other than hinoki oil in the cleansing agent according to this embodiment, essential oils other than hinoki oil may be used. Examples of essential oils other than hinoki oil include ylang-ylang, orange, roman chamomile, clarissa, grapefruit, cypress, sandalwood, cedarwood, jasmine, juniper, spearmint, geranium, thyme, tea tree, neroli, pine, patchouli, palmarosa, hinoki, petitgrain, frankincense, peppermint, bergamot, holy leaf, mandarin, marjoram, momi, eucalyptus globulus, eucalyptus citriodora, eucalyptus radiata, yuzu, lime, lavender, lemon, lemongrass, rose, rosemary, Japanese mint, etc.
[0022] Regarding substances other than hinoki oil in the cleansing agent according to this embodiment, various raw materials commonly used in cosmetics, for example, polyhydric alcohols such as glycerin and butylene glycol, organic and inorganic powders, components derived from natural products such as plants or microorganisms, ethanol, moisturizing components, pH adjusters, neutralizers, preservatives, antioxidants, fragrances, colorants, functional components such as beauty components, can be blended within a range that does not impair the effects of the cleansing agent according to this embodiment.
[0023] The cleansing agent according to this embodiment is suitable for a wide range of makeup products, from base makeup such as makeup primer, foundation, concealer, and finishing powder, to point makeup such as mascara, eyeliner, eyebrow pencil, eyeshadow, blush, and lipstick. In particular, the cleansing agent according to this embodiment exhibits a high removal rate for lipstick and can be effectively used as a point makeup remover.
[0024] The cleansing agent according to this embodiment can be manufactured by stirring and mixing cypress oil with other raw materials. The stirring may be done by machine or by hand. The cleansing agent according to this embodiment can be stored at room temperature, but storage in a cool, dark place is preferable.
[0025] The cleansing agent according to this embodiment is primarily intended for oil-type formulations, but it can also be applied to other formulations such as lotions, creams, gels, two-layers, semi-solids, and solids. Furthermore, the cleansing agent according to this embodiment can be impregnated into a sheet such as a nonwoven fabric to create a cleansing sheet for use.

All five ingredients of the cleansing agent according to Example 1 were placed in a glass container and mixed uniformly while stirring at room temperature to obtain 100g of the cleansing agent according to Example 1, which is a yellow, transparent oil.
[0028] Lipstick (Maybelline New York SP Stay Matte Ink, color number 20, manufactured by L'Oréal Japan Co., Ltd.) was applied to a glass slide in a 1.4 cm square area to a dry weight of 5 mg ± 1 mg, and dried at room temperature for at least one day. This was used as a test piece to test the cleansing power of the cleansing agent according to Example 1 on lipstick. At room temperature, 40 μl of the cleansing agent according to Example 1 was dropped onto the lipstick on the test piece, rubbed eight times with a finger, then rinsed three times with a sufficient amount of tap water at 38°C ± 1°C, and the test piece was allowed to air dry to obtain a test piece (lipstick) after cleansing according to Example 1. The lipstick removal rate (%) was calculated from the weight of the lipstick on the test piece before and after cleansing according to the following formula 1. The same procedure was performed six times with different test pieces. (Equation 1) Lipstick removal rate (%) = (1 - weight of lipstick after cleansing / weight of lipstick before cleansing) × 100 As shown in the table in Figure 2 and the graph in Figure 3, the average lipstick removal rate for the cleansing agent in Example 1 was 21%.
