Abstract
Description
本発明は、長期保存包装された液体組成物に関する。より詳細には、本発明は液体組成物を充填した合成樹脂製容器をさらにラミネート包装した長期保存に耐えうる液体組成物に関する。 The present invention relates to a liquid composition packaged for long-term storage. More specifically, the present invention relates to a liquid composition that can withstand long-term storage by further laminating a synthetic resin container filled with the liquid composition.
自然災害が多発傾向にある今日において、防災目的で化粧品などの種々の身の回り用品を備蓄されており、長期間保存可能な身の回り品の提供が望まれている。一般に化粧品などの商品は常温で3年間以上の品質を確保する設計が成されているが、この期間を5年以上とするためには、長期保存のための容器や包装に工夫する必要がある。一方、食品分野において5年以上の長期保存するためには、内容物を乾燥して封入する方法や、内容物を封入後レトルト処理など高温で過熱処理する方法などが取られているが、何れの方法も化粧品や医薬部外品などの液体状の身の回り用品に対して採用することができない。 Today, natural disasters tend to occur frequently, and various personal belongings such as cosmetics are stockpiled for disaster prevention, and it is desired to provide personal belongings that can be stored for a long period of time. In general, products such as cosmetics are designed to ensure a quality of 3 years or more at room temperature, but in order to make this period 5 years or more, it is necessary to devise containers and packaging for long-term storage. . On the other hand, in order to preserve for a long period of 5 years or longer in the food field, a method of drying and enclosing the content, a method of performing a heat treatment at a high temperature such as a retort treatment after enclosing the content, etc. are taken. This method cannot be applied to liquid personal items such as cosmetics and quasi drugs.
容器包装の材料の観点では、液体組成物を長期保存するためには、一般にガラス製や金属製の容器が使用されている。しかし、ガラス製容器の場合、物理的衝撃などによる破損の危険性があるだけでなく、容器自体の質量が大きくなるため、内容物量に対する質量が大きくなりすぎて扱いにくい欠点がある。一方、金属製容器の場合、内容物の種類によっては金属腐食や組成物への容器素材の溶解などの恐れがあるため、内容物の特性に応じて表面加工などを設計する必要が有るだけでなく、商品使用時の保存性を考慮した密封性の高い容器設計を行った場合、容器構造が複雑となり、金属材質の制限や製造コストが高くなるなどの課題が存在する。一方、一般的に容器素材として使用されている合成樹脂を用いた場合、組成物の水分や香料などの揮発成分が容器材を通して蒸散するため、香気が変化したり、原料臭のマスキングが不十分になったり、組成物を構成する成分比が大きく変化する恐れがある。このため長期保存期間中の商品品質を担保できないことから、長期保存ができない。そこで、容器の材質を複合化し、例えばエチレン・ビニルアルコール共重合体の層を構成することにより容器壁のバリア性を高める(特許文献1)などが提案されているが、容器材質の複合化は相互の材質の接着性から設計上の制限があったり、容器の成形過程における課題が生じたり、コストが高くなるなどの課題があった。 From the viewpoint of container packaging materials, glass or metal containers are generally used for long-term storage of liquid compositions. However, in the case of a glass container, there is not only a risk of breakage due to physical impact or the like, but also the disadvantage that the mass of the container itself becomes large, so that the mass with respect to the content amount becomes too large to be handled. On the other hand, in the case of a metal container, depending on the type of contents, there is a risk of metal corrosion or dissolution of the container material in the composition, so it is only necessary to design the surface treatment etc. according to the characteristics of the contents In addition, when a container design with high hermeticity in consideration of storage stability at the time of product use is performed, the container structure becomes complicated, and there are problems such as restrictions on metal materials and high manufacturing costs. On the other hand, when using a synthetic resin that is generally used as a container material, volatile components such as moisture and fragrance of the composition evaporate through the container material, so the aroma changes and masking of raw material odor is insufficient Or the ratio of components constituting the composition may change significantly. For this reason, since product quality during a long-term storage period cannot be secured, long-term storage cannot be performed. Therefore, it has been proposed to increase the barrier property of the container wall by compositing the material of the container, for example, by forming a layer of ethylene / vinyl alcohol copolymer (Patent Document 1). There have been problems such as design limitations due to the adhesiveness between the materials, problems in the container molding process, and increased costs.
本発明は、上記した従来技術の現状に鑑みてなされたものであり、5年以上の長期において安定的に保存しうる化粧品などの液体や液状の組成物を提供することを目的とする。 The present invention has been made in view of the above-described state of the art, and an object of the present invention is to provide liquids and liquid compositions such as cosmetics that can be stably stored for a long period of 5 years or longer.
本発明者らは、上記した目的を達成すべく鋭意研究を重ねた結果、驚くべきことに、組成物を充填した合成樹脂製容器を、特定の水蒸気透過度および酸素透過度を有するラミネートのパウチで包装することにより、5年以上の組成物の安定性を保証できることを見出した。本発明者らはかかる知見に基づきさらなる研究を重ねることにより、本発明を完成させるに至った。 As a result of intensive studies to achieve the above-mentioned object, the present inventors have surprisingly found that a synthetic resin container filled with the composition is made into a pouch of a laminate having a specific water vapor permeability and oxygen permeability. It was found that the stability of the composition for 5 years or more can be ensured by packaging with. The present inventors have completed the present invention by repeating further studies based on such findings.
即ち、本発明は以下の項に記載の主題を包含する。
項1.香料および/またはエチルアルコールを配合した組成物が充填された合成樹脂製容器を、水蒸気透過度が2(g/m2/24h)以下でかつ酸素透過度が10(ml/m2/24h)以下であるラミネート包材で構成されたパウチで包装した、長期保存用組成物。
項2.液体若しくは液状の組成物である項1に記載の長期保存用組成物。
項3.化粧品または口腔用組成物である、項1又は項2のいずれか1項に記載の長期保存用組成物。
That is, the present invention includes the subject matters described in the following sections.
Item 1. Perfumes and / or ethyl synthetic resin container alcohol compositions incorporating filled, the water vapor permeability of 2 (g / m 2 / 24h ) or less and an oxygen permeability of 10 (ml / m 2 / 24h ) The composition for a long-term preservation | save packaged with the pouch comprised with the following laminate packaging materials.
Item 2. Item 2. The composition for long-term storage according to Item 1, which is a liquid or liquid composition.
Item 3. Item 3. The composition for long-term storage according to any one of Items 1 or 2, which is a cosmetic or oral composition.
本発明によれば、5年以上の長期間において液体若しくは液状の化粧品や口腔用組成物が安定的に保存することが可能となる。その結果、防災用品として備蓄する場合の備蓄品の更新サイクルを大幅に延長できるため、保守管理が軽減できるだけでなく、大きな経済効果も期待できる。 According to the present invention, liquid or liquid cosmetics and oral compositions can be stably stored for a long period of 5 years or longer. As a result, since the renewal cycle of stockpiling products when stockpiling as disaster prevention supplies can be greatly extended, not only maintenance management can be reduced, but also a great economic effect can be expected.
以下、本発明について詳細に説明する。 Hereinafter, the present invention will be described in detail.
本発明の香料および/またはエチルアルコールを配合した組成物は、少なくとも香料かエチルアルコールを配合した人体用若しくは家庭用のケア用品を意味する。特に、水を主な溶媒とする液体若しくは液状の組成物において顕著な効果を示す。構成樹脂容器に充填した組成物の組成変化を防ぐことができることから、香気や組成物の使用性、防腐性、医薬品や医薬部外品などの組成変化に対する厳密な品質管理が要求される人体用ケア用品に最適である。なお、液体若しくは液状とは、20℃の常温において流動性を有する状態を意味する。 The composition containing the fragrance and / or ethyl alcohol of the present invention means a human or household care product containing at least a fragrance or ethyl alcohol. In particular, a remarkable effect is exhibited in a liquid or liquid composition containing water as a main solvent. Because it is possible to prevent compositional changes in the composition filled in the resin container, it is for the human body that requires strict quality control against changes in the composition of fragrances, composition usability, antiseptic properties, pharmaceuticals and quasi-drugs, etc. Ideal for care products. Liquid or liquid means a state having fluidity at a room temperature of 20 ° C.
本発明の合成樹脂製容器は、ブロー成形で製造される合成樹脂製もしくはラミネート材製の容器であれば特に限定されない。また、容器の容量や形状に関しても特に限定されない。 The synthetic resin container of the present invention is not particularly limited as long as it is a synthetic resin or laminate material container manufactured by blow molding. Further, the capacity and shape of the container are not particularly limited.
