【従来の技術】
ビタミンAおよび/またはその脂肪酸エステルは、肌荒れの改善、皮膚角化症等の予防や治療、さらには皮膚老化の防止や回復等に有効な成分であることが知られている。しかしながら、ビタミンAおよび/またはその脂肪酸エステルは、構造的に極めて不安定であり、光、空気、熱、金属イオン等により容易に種々の異性化、分解、重合等を起こすため、安定に化粧料に配合することが困難であった。上述した問題点を解決するために酸化防止剤、金属イオン封鎖剤(キレート剤)を配合したり、多量の油分を配合するなどの取り組みがなされている。例えば化粧料関連では、酸化防止剤及び金属イオン封鎖剤とを含有してビタミンA類を安定化する技術が開示されている。(例えば、特許文献1、同2、同3参照)
【0003】
一方、ビタミンA類を特定の極性油に溶解すると安定に保たれ、更に抗酸化剤を添加すると更なる安定性の向上が図れるとの技術も開示されている。(例えば、特許文献4参照)また、ビタミンA類の保存に関して、新鮮な植物油に溶解し、酸化防止剤(dl−α−トコフェロール、ジブチルヒドロキシトルエンなど)などを添加して保存するとの記載もある。(例えば、非特許文献1参照)このように油分に溶解させた油性タイプの化粧料では、ビタミンAおよび/またはその脂肪酸エステルの保存安定性は優れるが、油のヌルツキやべたつきを生じたり使用感が悪くなることがあった。また、さっぱり感を付与する目的で、この油性タイプに水を乳化させた油中水型乳化タイプのものは、製剤としての安定性を確保するために、油剤の種類や配合量などに制約があり、このために、十分満足できる使用感を得ることは困難であった。また、ビタミンAに起因するべたつきを抑えるために、ビタミンA類を含有する皮膚外用剤に有機粉末や、無機顔料、焼結顔料、有機顔料等の粉末を配合した技術も開示されている。(例えば、特許文献5参照)

[Prior art]
Vitamin A and / or fatty acid esters thereof are known to be effective components for improving rough skin, preventing and treating cutaneous keratosis, and preventing and recovering skin aging. However, vitamin A and / or fatty acid ester thereof is structurally extremely unstable and easily undergoes various isomerization, decomposition, polymerization, etc. by light, air, heat, metal ions, etc. It was difficult to blend in. In order to solve the above-mentioned problems, efforts such as blending an antioxidant and a sequestering agent (chelating agent) and blending a large amount of oil have been made. For example, regarding cosmetics, a technique for stabilizing vitamin A by containing an antioxidant and a sequestering agent is disclosed. (For example, see Patent Documents 1, 2, and 3)
[0003]
On the other hand, a technique is disclosed in which vitamin A is kept stable when dissolved in a specific polar oil, and further stability can be improved by adding an antioxidant. (For example, refer patent document 4) Moreover, regarding preservation | save of vitamin A, there exists description that melt | dissolves in a fresh vegetable oil, and adds and preserve | saves antioxidants (dl-alpha-tocopherol, dibutylhydroxytoluene etc.). . (For example, see Non-Patent Document 1) In the oily type cosmetics dissolved in the oil as described above, the storage stability of vitamin A and / or fatty acid ester thereof is excellent. Sometimes got worse. In addition, for the purpose of imparting a refreshing feeling, the water-in-oil type emulsified type in which water is emulsified in this oily type has restrictions on the type and blending amount of the oil agent in order to ensure the stability as a preparation. For this reason, it has been difficult to obtain a satisfactory use feeling. In addition, a technique in which organic powder, powders such as inorganic pigments, sintered pigments, and organic pigments are blended with an external preparation for skin containing vitamin A in order to suppress stickiness caused by vitamin A is also disclosed. (For example, see Patent Document 5)
