Pharmaceutical compounds distribution and cosmetic products analyzed by confocal Raman spectroscopy
Pharmaceutical compounds distribution and cosmetic products analyzed by confocal Raman spectroscopy
In the final step of the formulation process, pharmaceutical and cosmetic industries have to control their products to check if the compounds' distribution in the final product, or in its application form, i.e. dispersed on a skin for an intracutaneous product, are homogenous and stable in order to guarantee the product's efficacy. In this paper, we present why confocal Raman microscopy is an excellent tool for product characterization after formulation.
Laser Diffraction Analysis of Methicone-treated Blended Iron Oxides
Iron oxides are magnetic black materials. The methicone treatment adds a degree of “slip” to the particles allowing for better color saturation although they still remain magnetic.
Spectroscopic Methods for Sunscreens Characterization
This Application Note outlines three different kinds of spectroscopic tools being used for the characterization of sunscreens, and discusses the obtained results. These include Fluorescence spectroscopy for photoactivity, Particle Size analysis for composition and Raman microscopy for formulation investigation.
Particle Analysis for Cosmetics
Many cosmetic products include particulate material or emulsions. Some examples of cosmetic products consisting of or including particulates include facial powders, moisturizers, and lipstick. The particle size distribution of these components effects appearance, stability, and protection.
Valuable analysis tool for cosmetics and skin characterization
Confocal Raman Spectroscopy is an important analytical tool in various fields and it has shown high efficiency for specific applications in the cosmetic and/or pharmaceutical fields. Its non-invasive behavior, and its high molecular sensitivity make it one of the preferred label-free analytical techniques to characterize materials such as skin and cosmetic products.
Particle Size and Shape for Ointments and Creams
This study utilizes the PSA300 automated image analysis system to quantify the size and shape of various ointments and creams.
Fast & Non-invasive Determination of Skin State
Fast and non-invasive determination of skin
Biological tissues contain chromophores that absorb light, as well as fluorophores that absorb and reemit light (fluorescence effect). Light absorption depends on the chromophores’ content and their distribution within the organic matter.
Visualizing dental caries using fluorescence lifetime microscopy
Teeth are naturally fluorescent and changes in their composition, caused by decay for example, affect their fluorescence behavior.
Endogenous Skin Fluorescence In Vivo on Human Skin
The fluorescence spectra of intrinsic protein fluorophores have been studied extensively and used in investigating biological events.
Noninvasive In-Vivo Determination of Sunscreen-UVA Protection Factors
Noninvasive In-Vivo Determination of Sunscreen-UVA Protection Factors
The development and evaluation of UVA (320–400 nm) sunscreens is important because UVA sunlight can penetrate deep into human skin and cause severe internal damage, as well as erythema and photoaging.
In Vivo Raman measurements of Human Skin
Confocal Raman spectroscopy is beginning to be recognized as a high potential technique for the non invasive study of biological tissues and human skin under in vivo conditions. Raman spectroscopy can be applied to obtain information regarding the molecular composition of the skin down to several hundred micrometers below the skin surface.
