Description

[Technical Field]

[0001] The present invention relates to a transparent mist-type cosmetic composition, and in particular to a transparent mist-type cosmetic composition that has high transparency at 20°C and 40°C, can be sprayed as a mist, is non-sticky, and has a fragrant aroma without an ethanol smell. [Background technology]

[0002] Fragrance cosmetics, which are primarily used to mask body odor and elevate mood, come in a variety of forms, including solid perfumes, sticks, and aromatic powders. However, mist-type perfumes, which are a mixture of ethanol and fragrance, are also common due to their ease of use. These perfumes tend to last longer and have a stronger scent. However, in recent years, with the rise in preference for natural products, water-based fragrance mists with subtle fragrances using natural fragrances such as essential oils have become increasingly popular, and are especially favored for masking body odor during hot weather.

[0003] Water-based fragrance mists use not only essential oils but also synthetic fragrances to impart their scent, and from an aesthetic point of view, transparent systems are preferred. However, because essential oils and fragrances are difficult to solubilize, transparent cosmetic formulations using various surfactants and organic solvents have been investigated.

[0004] For example, in Patent Document 1, a cosmetic containing oil-soluble ingredients such as essential oils and fragrances is solubilized by combining polyoxyethylene hydrogenated castor oil with polyoxyethylene dioleate or polyoxyethylene diisostearate to obtain a cosmetic containing oil-soluble ingredients that are stable for a long period of time. In Patent Document 2, a cosmetic containing a large amount of fragrance solubilized is obtained by adjusting the blending ratio of polyoxyethylene hydrogenated castor oil and polyoxyethylene polyoxypropylene alkyl ether. In Patent Document 3, a transparent cosmetic is obtained without increasing the amount of surfactant by blending the oil-soluble ingredients and phenoxyethanol together in advance to homogenize them.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-83496 [Patent Document 2] International Publication No. 2020 / 095429 [Patent Document 3] Japanese Patent Application Laid-Open No. 2008-195676 Summary of the Invention [Problem to be solved by the invention]

[0006] However, while all of the above patent documents solve the problem of obtaining cosmetics with a transparent appearance, they do not address the stickiness caused by surfactants or mist-type formulations. Furthermore, with global warming, temperatures can exceed 40°C in midsummer, and some types of oily ingredients have difficulty maintaining transparency at 40°C, so maintaining transparency at 40°C is also required from the perspective of beautiful appearance.

[0007] Therefore, an object of the present invention is to provide a transparent mist-type cosmetic composition that is highly transparent not only at room temperature (20°C) but also at 40°C, can be sprayed as a mist, is non-sticky, and has a fragrant aroma without an ethanol smell. [Means for solving the problem]

[0008] In light of these circumstances, the present inventors conducted extensive research and discovered that a transparent mist-type cosmetic composition containing (A) one or more oils selected from orange oil, bergamot fruit oil, lemon fruit oil, peppermint oil, eucalyptus oil, rosemary oil, spearmint oil, ylang-ylang flower oil, and lavender oil, (B) one or more oils selected from POE·POP alkyl ethers, (C) one or more oils selected from propylene glycol, dipropylene glycol, and ethylene glycol, (D) ethanol, and (E) trimethylglycine can be obtained, resulting in a transparent mist-type cosmetic composition that is highly transparent at 20°C and 40°C, can be sprayed as a mist, is non-sticky, and has a fragrance that can be sensed without the smell of ethanol, thereby completing the present invention. [Effects of the Invention]
