White petrolatum is widely used as an ointment base.In this study,we examined the quality characteristics of pharmaceutical petrolatums and a cosmetic petrolatum.There are 6 brands of pharmaceutical white petrolatum which are Perfecta and White 1S made by Sonneborn Co.and Ultima,Snow,Snow V and Regent made by Penreco Co.<br>We measured the melting point and viscosity of the white petrolatums.Perfecta had the highest melting point and Ulitima had the lowest.Snow had the highest viscosity and Perfecta the lowest.These results show that the characteristics of white petolatums vary among brands.Spectrophotometry was used to evaluate potential allergenicity.For extracts of Ultima,Regent and a cosmetic petrolatum,absorption was not observed in the 260 to 270 nm range suggesting that Ultima,Regent and the cosmetic petrolatum have a low content of polycyclic aromatic hydrocarbons which cause skin irritation.Upon investigating the brands of white petrolatum used in the base of commercial ointments,we found that the brand of petrolatum varied among the ointments.In order to ensure the proper use of ointments,suitable ointments should therefore be selected in consideration of patient needs.

2016年は「VR元年」と謳われた年であり,マーケティングのトレンドも「ユーザー体験(UX)」が主流になると予想されている。大学図書館でも「どれだけリッチなユーザー体験を提供できるか」が今後の利用者サービスの柱となることが想起された。同年,開館25周年を迎えた早稲田大学中央図書館では,バーチャルリアリティー(VR)を活用した「夢の融合プロジェクト」が実施され,学内の部署間連携や教職員・学生の協働が織り成すチャレンジングかつエキサイティングなプロジェクトとなった。本稿は,その舞台裏を支えた図書館スタッフの魂のVR制作ストーリーである。

Very little information is provided with OTC drugs and unlike prescription products,they do not have package inserts or interview forms.The purpose of this study was to examine the stability of 5 acetaminophen-containing OTC drugs by observing temporal changes in their characteristic physico-pharmaceutical parameters (hardness,mass,elution,drug migration) when they were preserved under conditions in which temperature and humidity were altered.From the results,it was assumed that 3 of the 5 drugs were affected by temperature and humidity,and that it was difficult to maintain stability when they were taken out of their packages.In particular,the drugs seemed to be more adversely affected the higher the temperature was and changes in parameters were greater.Also,the results of an elution test conducted after 24 hours of storage suggested that there was deterioration in 3 of the products.In conclusion,our findings clearly showed that patients need adequate explanation on how to keep OTC drugs.
