化学的特性
ベンジルサリシレートは化学式C14H12O3で表される芳香族化合物ですこの化合物はサリチル酸とベンジルアルコールのエステルであり主に香料や化粧品業界で用いられます自然界ではいくつかの花や植物に微量で存在しておりその甘く花のような香りが特徴です説明
Benzyl salicylate is a salicylic acid benzyl ester, a chemical compound most frequently used in cosmetics. It appears as an almost colorless liquid with a mild odor described as "very faint, sweetfloral, slightly balsamic" by those who can smell it, but many people either can't smell it at all or describe its smell as "musky". Trace impurities can have a significant influence on the odour.[1] It occurs naturally in a variety of plants and plant extracts and is widely used in blends of fragrance materials.There is some evidence that people can become sensitized to this material and as a result there is a restriction standard concerning the use of this material in fragrances by the International Fragrance Association.
It is used as a solvent for crystalline synthetic musks and as a component and fixative in floral perfumes such as carnation, jasmine, lilac, and wallflower.
化学的特性
Benzyl Salicylate occurs in several essential oils, is a colorless, viscous liquid with a weak, sweet, slightly balsamic odor and a sweet, currant-like taste. It is soluble in ethanol, most non-volatile and volatile oils, slightly soluble in propylene glycol, insoluble in glycerin and practically insoluble in water.天然物の起源
It has been reported in small amounts in carnation oil (Dianthus caryophyllus L.) and in larger amounts in the oil of Primula auricula. Also found in American cranberry, clove bud, peppermint oil and buckwheat.使用
Benzyl Salicylate is an chemical compound commonly used in the cosmetic industry. Benzyl Salicylate is also found in essential oils from green tea and was shown to exhibit antioxidant and antimicrobia l activity.製造方法
By esterification of salicylic acid with benzyl alcohol.安全性
ベンジルサリシレートの使用は化粧品や香料業界で広く受け入れられていますがその安全性に関しては慎重な検討が必要です多くの国ではこの化合物の使用に関して規制やガイドラインが設けられており製品に含まれる濃度に上限がありますこれは消費者の健康を保護するための措置です一般的な説明

Slightly water soluble .反応プロフィール
Benzyl salicylate may hydrolyze in aqueous acid or basic solutions. Benzyl salicylate can react with oxidizing materials.火災危険
Flash point data for Benzyl salicylate are not available, but Benzyl salicylate is probably combustible.接触アレルゲン
Benzyl salicylate is used as fixer in perfumery and sunscreen preparations. As a (weak) perfume sensitizer, it has to be listed by name in cosmetic preparations in the EU.安全性プロファイル
Moderately toxic by ingestion. Seealso BENZYL ALCOHOL, SALICYLIC ACID, andESTERS. Combustible when exposed to heat or flame.When heated to decomposition it emits acrid smoke andirritating fumes. Incompatible with oxidizing materials.安全性
Benzyl salicylate poses dangers to sensitive skin. Even in very small amounts, it may cause allergic reactions when applied to the skin. Benzyl salicylate can cause contact dermatitis (skin irritation) to people with sensitive skin types. It is also on the European Commission's list of 26 known allergens. Some of the other ingredients on the fragrance allergen list include linalool, coumarin, geraniol, and limonene.参考文献
