资料摘要
资料下载Double emulsions are colloidal systems of great interest for the cosmetics industry as they enable to encapsulate both hydrophilic and lipophilic molecules. However, their formulation is very delicate and requires an important know-how. Their characterisation is also quite limited with classical techniques that, for most of them require dilution (particle size), or are not quantitative (microscopy). The study of the kinetics of release of the active encapsulated in the internal emulsion is also very interesting for the formulator. However, here again, very few techniques are available apart from the Turbiscan Lab (see application note “Study of the release of an encapsulated active in a double emulsion”).

如何实现对低粘度流体进行高精度测量
简介：Analyzing highly liquid products such as vaccines or water-based formulations is a delicate matter as traditional techniques are insensitive to low viscosities. Fluidicam technology allows for fast and precise measurements even for low viscosity products with minimal sample volume.
多重光散射仪在药物制剂中的应用
简介：The world of drug delivery is getting every day more efficient with new product forms, which are directly targeting the deficient organs. Colloidal systems such as emulsions (simple or multiple) or nanoparticle suspensions are now widely used as drug carriers or nutritional solutions in this respect. These new product forms allow better targeting and assimilation for the patient, and give rise to new solutions for drug designers. However, the stability of these inherently unstable colloidal systems makes them complex to formulate and study.
多重光散射仪在石油领域中的应用
简介：Asphaltenes are causing major problems in the extraction process of crude oil as they can lead to fouling & clogging in pipes or even in the entire well when they aggregate. Moreover asphaltenes play the role of natural emulsifier which stabilises water-in-oil emulsions formed during production of crude oil. Asphaltenes also have an impact on the refinery efficiency and the fuel oil quality. To overcome these technical issues, chemical additives are used. It is therefore important to have a technique that can identify the most suitable additive, but also to measure accurately the stability of oil or emulsions

Gelling of an emulsion
简介：Gelling can be obtained through two main mechanisms: creation of a network due to a reticulation of polymers (it is the case for gelatin) or aggregation of particles (it is the case in yogurt). In the cosmetics industry it is commonly used to get various textures.
