Description
本発明は、クレンジング剤、洗顔料、手洗い剤、身体洗浄剤等の洗浄料、マッサージ料等の化粧料に用いるスクラブ剤に関する。
The present invention relates to a scrub agent used for a cleansing agent, a cleansing agent such as a cleansing agent, a face wash, a hand washing agent, a body cleansing agent, and a cosmetic agent such as a massage agent.
従来より、洗浄料やマッサージ料等の化粧料には、皮膚の汚れや古い角質の除去、マッサージ効果を得ること等を目的としてスクラブ剤を配合している。従来のスクラブ剤としては、合成樹脂の粒子（マイクロビーズ等）、炭酸カルシウムの粒子、クルミやアンズ等の植物種子を粉砕した粒子、キャンデリラワックスやカルナウバロウ等の天然ワックスの粒子等が用いられている（特許文献１～５）。
Heretofore, scrubbing agents have been added to cosmetics such as cleansing agents and massage agents for the purpose of removing dirt from the skin and old keratin and obtaining a massage effect. As conventional scrubbing agents, particles of synthetic resin (microbeads etc.), particles of calcium carbonate, particles of crushed plant seeds such as walnut and apricot, particles of natural wax such as candelilla wax and carnauba wax, etc. are used. (Patent Documents 1 to 5).
しかし、合成樹脂や炭酸カルシウム等は、自然界に排出されると長期にわたり残り続け、生態系にとどまり、更に蓄積することで様々な影響を及ぼす可能性がある。また、植物種子を粉砕した粒子は、不定形で鋭い割面を有するものが多いため、皮膚や目の角膜等を損傷するという問題を生ずる可能性がある。そして、天然ワックスの粒子は、天然ワックス自体が天然物であるために安定供給が難しく更に要求する性能に調整することが難しいという問題がある。そこで、自然環境や人体への悪影響が少なく、要求する性能に調整しやすい化学的に合成可能な合成ワックスであるスクラブ剤が求められていた。
However, synthetic resins and calcium carbonate, etc., if left in the natural world, will remain for a long time, stay in the ecosystem, and have various effects by further accumulating. In addition, many particles obtained by crushing plant seeds may cause problems such as damage to the skin or the cornea of the eye, because they have an irregular shape and a sharp fractured surface. The particles of natural wax have a problem that stable supply is difficult because the natural wax itself is a natural product, and it is difficult to adjust to the required performance. Therefore, there has been a demand for a scrubbing agent that is a chemically synthesizable synthetic wax that is less likely to adversely affect the natural environment or human body and can be easily adjusted to the required performance.
本発明の目的は、化学的に合成可能な合成ワックスである多価アルコール脂肪酸エステルを主成分とする化粧料用スクラブ剤を提供することである。

例えば、クレンジング料であれば、スクラブ剤は化粧料組成物中に０．１～２０質量％を配合することができ、更に保湿剤、油剤、脂肪酸類、界面活性剤、アルカリ物質、アルコール類、エステル類、消炎剤、金属封鎖剤、ビタミン類、酸化防止剤、増粘剤、精製水、ｐＨ調節剤、香料、防腐剤、殺菌剤、着色料、本発明のスクラブ剤以外のスクラブ剤等を適宜選択して配合することができる。
For example, in the case of a cleansing agent, the scrub agent can be blended in an amount of 0.1 to 20% by mass in the cosmetic composition, and further, a moisturizer, an oil, fatty acids, surfactants, alkaline substances, alcohols, Esters, anti-inflammatory agents, sequestering agents, vitamins, antioxidants, thickeners, purified water, pH adjusters, flavors, preservatives, bactericides, coloring agents, scrub agents other than the scrub agents of the present invention, etc. It can be selected appropriately and blended.
本発明の化粧料組成物は、本発明のスクラブ剤を含有しているので、皮膚表面を傷つけることなく低刺激で効果的に皮膚上の汚れを取り除くことができる。また、スクラブ剤を含有する化粧料組成物を洗い流しても、合成樹脂の粒子（マイクロビーズ等）の様に自然界に長期にわたり生態系にとどまり、更に蓄積することはないので、環境に対して悪影響を及ぼす可能性が低い。
Since the cosmetic composition of the present invention contains the scrub agent of the present invention, it is possible to remove dirt on the skin effectively with low irritation without damaging the skin surface. In addition, even if the cosmetic composition containing the scrub agent is washed away, it does not stay in the ecosystem for a long time in the natural world like synthetic resin particles (microbeads etc.) and accumulates further, so it has an adverse effect on the environment. The possibility of exerting is low.
以下に本発明を実施例で説明するが、これは本発明を単に説明するだけのものであって、本発明を限定するものではない。
The invention will now be described by way of example, which is merely illustrative of the invention and is not limiting.
