Description
本発明は、多価アルコールの含有量が多い場合でも、塗布後にずるつきやべたつきを感じることのない良好な使用感を持ち、経時安定性に優れた、防腐剤を含まない水中油型乳化化粧料に関する。 The present invention relates to a preservative-free oil-in-water emulsion cosmetic that has a good feel when applied without feeling sticky or sloppy, even when it contains a large amount of polyhydric alcohol, and has excellent stability over time.
近年、敏感肌であると自覚する消費者が増加している。敏感肌とは刺激に対する応答としてかゆみや痛み、チクチク感など通常は引き起こされない不快な感覚が発生する肌であるとされ、敏感肌の特徴としては主にバリア機能の低下や刺激閾値の低下、潜在的な炎症性病態が挙げられている。日本人女性における敏感肌意識調査の結果、自身の肌が敏感肌であると意識する消費者は調査対象者の約77%であると報告されている(非特許文献1)。 In recent years, the number of consumers who are aware that they have sensitive skin has been increasing. Sensitive skin is said to be skin that responds to stimuli with unpleasant sensations that are not normally caused, such as itching, pain, and a tingling sensation, and the main characteristics of sensitive skin include a reduced barrier function, a reduced stimuli threshold, and potential inflammatory conditions. A survey of Japanese women on their awareness of sensitive skin reported that approximately 77% of the survey subjects were aware that they had sensitive skin (Non-Patent Document 1).
敏感肌においては一般的な化粧品原料についても刺激の原因となることがあるため、敏感肌の消費者からは極力不要な成分を配合しない製品が求められている。特に防腐剤は皮膚の一時的なかゆみやヒリヒリ感といった感覚刺激を引き起こしたり、皮膚の炎症や接触アレルギーの主な原因のひとつとなる場合があるともいわれているため、敏感肌の消費者などからは防腐剤を含まない化粧料が求められている。 Since even common cosmetic ingredients can cause irritation to sensitive skin, consumers with sensitive skin are looking for products that contain as few unnecessary ingredients as possible. In particular, preservatives can cause sensory irritation such as temporary itching and tingling on the skin, and are said to be one of the main causes of skin inflammation and contact allergies, so consumers with sensitive skin are looking for cosmetics that do not contain preservatives.
しかし化粧料の製造段階及び消費者による使用段階における微生物汚染は、腐敗、変敗などを引き起こし、その結果変臭や変色といった品質劣化を生じさせるのみならず、人体に健康被害をもたらす危険性もあるため、化粧料に防腐効果を持たせることは必要不可欠である。そこで、一般的に防腐剤を含まない化粧料には防腐剤と同等の防腐効果を得るために、多価アルコールを組成物中10~20重量%と高配合することが必要となる。しかし、多価アルコールの含有量が多いと塗布後にずるつきやべたつきを感じることがあり、また、経時安定性が悪くなることがある(特許文献1)。 However, microbial contamination of cosmetics during the manufacturing stage and during use by consumers can cause spoilage and deterioration, resulting in quality deterioration such as odor and discoloration, as well as the risk of posing a health risk to the human body, making it essential for cosmetics to have a preservative effect. Therefore, in general, cosmetics that do not contain preservatives must contain a high amount of polyhydric alcohol, at 10 to 20% by weight in the composition, in order to obtain the same preservative effect as preservatives. However, if the polyhydric alcohol content is high, the product may feel sticky or slippery after application, and its stability over time may be poor (Patent Document 1).
これまでに、防腐剤を含まず経時安定性に優れ、べたつき感のない乳化組成物を提供した例としては、1,2-アルカンジオール、界面活性剤、油性物質および水を含有することを特徴とする乳化組成物(特許文献1)が知られているが、多価アルコールが高配合された場合の塗布時のずるつきやべたつきを十分に改善するものではない。また、防腐剤を使用せずに安全性や防腐効果、使用感に優れた皮膚外用剤を提供した例として、1,3-ブチレングリコール、ジプロピレングリコール及び1,2-ペンタンジオールを含有することを特徴とする皮膚外用剤(特許文献2)が知られているが、多価アルコールが高配合された場合の経時安定性に優れているとはいえない。 As an example of an emulsion composition that does not contain preservatives, has excellent stability over time, and is not sticky, there is an emulsion composition (Patent Document 1) that contains 1,2-alkanediol, a surfactant, an oily substance, and water, but this does not sufficiently improve the slippery and sticky feeling when applied when a high amount of polyhydric alcohol is included. In addition, as an example of an external skin preparation that does not use preservatives and has excellent safety, preservative effect, and usability, there is an external skin preparation (Patent Document 2) that contains 1,3-butylene glycol, dipropylene glycol, and 1,2-pentanediol, but it cannot be said that it has excellent stability over time when a high amount of polyhydric alcohol is included.
本発明は、多価アルコールの含有量が多い場合でも、塗布後にずるつきやべたつきを感じることのない良好な使用感を持ち、経時安定性に優れた、防腐剤を含まない水中油型乳化化粧料を提供することを課題とする。 The objective of the present invention is to provide a preservative-free oil-in-water emulsion cosmetic that has a good feel when applied without feeling sticky or slippery even when it contains a large amount of polyhydric alcohol, and has excellent stability over time.
即ち、本発明は、次の成分(a)~(f)
(a)ダイマー酸エステル
(b)リンゴ酸ジイソステアリル
(c)1,3-ブチレングリコール、プロピレングリコール及びジプロピレングリコールから選ばれる1種又は2種以上の多価アルコール
(d)ショ糖脂肪酸エステル
(e)ポリグリセリン脂肪酸エステル
(f)ペンチレングリコール
を含有し、成分(a)の含有量が0.05~2.0重量%であり、成分(b)の含有量が0.5~6.0重量%であり、成分(c)の含有量が12.0~25.0重量%であり、成分(d)と成分(e)の総量が1.0~3.0重量%であり、重量比(e)/(d)が0.5~12.0であり、成分(f)の含有量が1.0~5.0重量%である、防腐剤を含まない水中油型乳化化粧料を提供するものである。
That is, the present invention relates to a composition comprising the following components (a) to (f):
The present invention provides an oil-in-water emulsion cosmetic composition containing no preservative, the oil-in-water emulsion cosmetic composition comprising: (a) a dimer acid ester; (b) diisostearyl malate; (c) one or more polyhydric alcohols selected from 1,3-butylene glycol, propylene glycol, and dipropylene glycol; (d) a sucrose fatty acid ester; (e) a polyglycerin fatty acid ester; and (f) pentylene glycol, the content of component (a) being 0.05 to 2.0% by weight, the content of component (b) being 0.5 to 6.0% by weight, the content of component (c) being 12.0 to 25.0% by weight, the total amount of components (d) and (e) being 1.0 to 3.0% by weight, the weight ratio (e)/(d) being 0.5 to 12.0, and the content of component (f) being 1.0 to 5.0% by weight.
また、本発明は、前記成分(a)がダイマージリノール酸(フィトステリル/イソステアリル/セチル/ステアリル/ベヘニル)である水中油型乳化化粧料を提供するものである。 The present invention also provides an oil-in-water emulsion cosmetic in which the component (a) is dimer dilinoleic acid (phytosteryl/isostearyl/cetyl/stearyl/behenyl).
また、本発明は、前記成分(d)がパルミチン酸スクロースであり、前記成分(e)がラウリン酸ポリグリセリル-10である水中油型乳化化粧料を提供するものである。 The present invention also provides an oil-in-water emulsion cosmetic in which the component (d) is sucrose palmitate and the component (e) is polyglyceryl-10 laurate.
本発明の水中油型乳化化粧料は、多価アルコールの含有量が多い場合でも、塗布後にずるつきやべたつきを感じることのない良好な使用感を持ち、経時安定性に優れた、防腐剤を含まない水中油型乳化化粧料である。 The oil-in-water emulsion cosmetic of the present invention is a preservative-free oil-in-water emulsion cosmetic that has a good feel when applied without feeling sticky or slippery even when it contains a large amount of polyhydric alcohol, and has excellent stability over time.
本発明の成分(a)ダイマー酸エステルの含有量は、水中油型乳化化粧料に対して0.05~2.0重量%であり、より好ましくは0.1~1.0重量%である。これらの範囲において、経時安定性に優れ、塗布後にずるつきやべたつきを感じることのない良好な使用感が得られる。本発明の成分(a)の含有量が0.05重量%より小さい場合、経時安定性が悪くなったりずるつきを感じることがあり、2.0重量%より大きい場合、べたつきを感じることがある。 The content of the dimer acid ester, component (a) of the present invention, is 0.05 to 2.0% by weight, and more preferably 0.1 to 1.0% by weight, relative to the oil-in-water emulsion cosmetic. Within these ranges, the cosmetic has excellent stability over time, and provides a good feel without slippery or sticky sensation after application. If the content of component (a) of the present invention is less than 0.05% by weight, the cosmetic may have poor stability over time or may feel slippery, and if it is more than 2.0% by weight, the cosmetic may feel sticky.
