Description

[Technical Field]

[0001] The present invention relates to a hair cosmetic, in particular to an oily hair cosmetic that does not contain silicones. [Background technology]

[0002] Silicones have traditionally been used extensively in a wide range of cosmetic applications, including skin care, hair care, makeup, and sun care, due to their excellent effects of imparting a smooth, light feel to the skin and hair and improving luster. In particular, in the field of hair care, silicones have been highly valued as essential ingredients not only in in-bath products such as shampoos, hair rinses, and hair conditioners, but also in leave-in products such as hair oils and hair waxes. However, in recent years, there has been a demand for the development of hair cosmetics that do not contain silicones, due to consumers' preference for natural materials and considerations of environmental impact, etc.

[0003] Against this background, various silicone alternatives have been developed and their incorporation into cosmetics has been proposed, but no cosmetics containing silicone alternatives that meet the above-mentioned consumer demands and have sufficient hair conditioning effects have yet been developed (Patent Documents 1 and 2).

As the (diisostearate / hydrogenated rosin acid) glyceryl, the commercially available product Vistanol GDHR (trade name, manufactured by Seiwa Kasei Co., Ltd.) can be used.

[0011] The amount of fatty acid triglyceride blended in the hair cosmetic of the present invention can be freely selected depending on the formulation and mode of the hair cosmetic of the present invention, but is preferably 0.1 to 30% by mass of the cosmetic, more preferably 1 to 20% by mass, and most preferably 5 to 15% by mass. If the blending amount is less than 0.1% by mass, it is difficult to fully exert the effect on hair, while if the blending amount exceeds 30% by mass, the effect commensurate with the blending amount cannot be obtained.

[0012] [Component (2): Oil other than component (1)] The oils incorporated into the hair cosmetic of the present invention dissolve fatty acid triglycerides and other ingredients, improve the stability of the formulation, and impart smoothness and manageability to the hair. The oils are not particularly limited as long as they are oils used in cosmetics, and any oil can be used. Oils may be used regardless of whether they are volatile or non-volatile, or whether they are derived from animal oils, vegetable oils, synthetic oils, etc., and include, for example, (C13-15) alkanes, (C15-19) alkanes, (C18-21) alkanes, (C21-28) alkanes, mineral oils, liquid paraffin, heavy liquid isoparaffin, light liquid isoparaffin, α-olefin oligomers, squalane, polyisobutylene, polyisobutene, polybutene, hydrogenated polyisobutene, isohexadecane, isododecane, microcrystalline wax, ceresin, Hydrocarbon oils such as petrolatum; waxes such as carnauba wax, candelilla wax, beeswax, rice bran wax, and shellac wax; oils and fats such as olive oil, castor oil, camellia oil, rice bran oil, macadamia nut oil, Theobroma grandiflorum seed butter, coconut oil, shea butter, and Astrocaryum murumuru seed butter; jojoba oil, diisobutyl adipate, isopropyl isostearate, cetyl 2-ethylhexanoate, neopentyl glycol dicaprate, isopropyl palmitate, 2-methylpropional Ester oils such as ethylhexyl, isononyl isononanoate, isopropyl myristate, 2-octyldodecyl myristate, and diisostearyl malate; amino acid oils such as N-lauroyl-L-glutamic acid 2-octyldodecyl ester and N-lauroyl-L-glutamic acid di(phytostearyl·2-octyldodecyl); higher fatty acids such as isostearic acid, oleic acid, lauric acid, myristic acid, palmitic acid, and stearic acid; octanol, lauryl alcohol Examples of suitable oleic acid oils include higher alcohols such as ethanol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, arachidyl alcohol, behenyl alcohol, coconut alcohol, (C14-22) alcohols, (C20-22) alcohols, hexyldecanol, octyldodecanol, batyl alcohol, oleyl alcohol, and isostearyl alcohol; and lanolin or lanolin derivatives, among which hydrocarbon oils, waxes, and ester oils are preferred.These oils may be blended singly or in combination.

[0013] The amount of oil in the hair cosmetic of the present invention can be freely selected depending on the formulation and mode of the hair cosmetic of the present invention, but is preferably 10 to 90% by mass of the cosmetic, more preferably 15 to 70% by mass, and most preferably 20 to 50% by mass. If the amount is less than 10% by mass, it is difficult to fully exert the effect on hair, while if the amount is more than 90% by mass, the effect commensurate with the increase in the amount cannot be obtained.

[0031] The present invention will now be described in detail with reference to examples, but the present invention is not limited to these examples. Note that all values ​​shown in the tables of the examples are in mass % relative to the total mass of the cosmetic.

[0032] Comparative Example 1 and Example 1: Hair Oil A hair oil was prepared by mixing the ingredients listed in Table 1 at room temperature. Furthermore, damaged hair was prepared and evaluated according to the hair feel evaluation method described below.

[0033] [Creating damaged hair] Damaged hair was prepared by bleaching to achieve a consistent level of damage. Specifically, healthy black hair tresses were immersed in 2% polyoxyethylene (3) sodium lauryl ether sulfate heated to 40°C and allowed to soak for 30 minutes using a heated soaking device. After 30 minutes of soaking, the tresses were washed with running tap water at 40°C and then dried with a hair dryer. Next, the tresses were bleached by immersing in a 1:1 (by weight) mixture of 6% hydrogen peroxide and 2% ammonia water at 30°C for 30 minutes, followed by washing with running tap water at 40°C. After towel drying, the tresses were immersed in a mixture of 0.1 M citric acid and 0.2 M disodium hydrogen phosphate as an acid rinse for 5 minutes at room temperature, followed by washing with running tap water at 40°C. The tresses were then soaked in ion-exchanged water at room temperature for 10 minutes, followed by towel drying and drying with a hair dryer. This bleaching procedure was repeated three times.

[0034] [Hair feel evaluation method] The prepared damaged hair bundle (30 cm long, 9 g weight) was wetted with water and towel-dried, after which 0.1 g of hair oil was applied, combed three times, and dried with a hair dryer. Five panelists evaluated the feel of the hair oil and the condition of the hair upon application, the finished condition of the hair after drying with a hair dryer, and the condition of the hair 2-3 hours after application of the hair oil using the following evaluation criteria, and the results are shown in Table 1. The results are shown as the average scores of the five panelists.

[0035] [Hair evaluation criteria] The result of Comparative Example 1 was set as the standard (0 points), and the evaluation was made in 0.5 point increments between -2 points and 2 points. The higher the score, the better the result.

[0036] [Table 1] In Table 1, *1 is Parleam 4 (trade name, manufactured by NOF Corporation), *2 is KF-96A-20cs (trade name, manufactured by Shin-Etsu Chemical Co., Ltd.), *3 is XF49-601 (trade name, manufactured by Momentive Performance Materials Japan), *4 is KF-8020 (trade name, manufactured by Shin-Etsu Chemical Co., Ltd.), *5 is EMOGREEN L15 (trade name, manufactured by SEPPIC), and *6 is Vistanol GDHR (trade name, manufactured by Seiwa Chemical Co., Ltd.).

[0037] The results in Table 1 reveal that the hair oil of Example 1, which contains component (1) glyceryl diisostearate / hydrogenated rosin acid, has a superior effect to the hair oil of Comparative Example 1, which contains silicones instead of glyceryl diisostearate / hydrogenated rosin acid.

[0038] Comparative Example 2 and Example 2: Hair wax (A) and (B) listed in Table 2 were mixed and heated to 85°C. (C) was mixed at room temperature and stirred until uniform. (B) was then added to (A) and stirred, and (C) was then added and stirred. (D) and (E) and the evaporated amount of water were then added to prepare a hair wax. Furthermore, the hair texture was evaluated according to the following hair evaluation method and hair evaluation criteria.

[0039] [Hair feel evaluation method] The hair of the cutting mannequin was blocked and 0.2 g of hair wax was applied to each section. Five panelists evaluated the feel of the hair wax when it was applied, the condition of the hair during styling, and 2-3 hours after application, using the following evaluation criteria, and the results are shown in Table 2. The results are shown as the average scores of the five panelists.

[0040] [Hair evaluation criteria] The result of Comparative Example 2 was set as the standard (0 points), and evaluation was carried out in increments of 0.5 points between -2 points and 2 points. A higher score indicates a better result.

[0041] [Table 2] In Table 2, *2 and *6 are the same as in Table 1.

[0042] The results in Table 2 reveal that the hair wax of Example 2, which contains component (1): glyceryl (diisostearate / hydrogenated rosin acid), has functions equal to or greater than those of Comparative Example 2, which contains silicones, and in particular provides excellent smoothness and hair volume.

[0043] The results in Tables 1 and 2 demonstrate that glyceryl diisostearate / hydrogenated rosinate exhibits excellent effects in hair oils and hair waxes that are comparable to those of silicones.
