Der volle Inhalt der QuelleIn the last 20 years, many non-invasive methods and techniques have been developed in order to measure the properties (physicochemical, sensory, etc.) of cosmetic products. These methods are designed to evaluate their safety and effectiveness, and become even more sophisticated as the processes of developing these products become complex and innovative.During this thesis works, a multi-scale study of the structural evolution of cosmetic emulsions was conducted in order to predict their textural and microbiological stability.The study of the link between the structural organization of these emulsions with their composition and their stability was one of the first challenges. Thanks to an ultrasonic non-destructive technique allowing access to micro-rheological properties (viscoelastic properties observed during a harmonic loading of shear at a few MHz), in association with different classical characterization techniques (optical microscopy, low frequency rheology, etc. .); it was possible to correlate the micro-rheological parameters obtained with physical models linking internal structuring and stability in the emulsions considered. The results showed that micro-rheological data are sensitive to variations in compositions (concentration) and microscopic organization of micelles within emulsions (flocculation, coalescence, etc.).Then, the follow-up of the evolution of Pseudomonas fluorescens bacteria in emulsions with different internal structures showed on the one hand the sensitivity of micro-rheology towards the presence of bacteria in the cream, and on the other hand, the impact of the structure and organization of micelles on the development of these bacteria.Finally, micro-rheology appears to be an innovative measurement method adapted on an industrial scale providing added value when developing cosmetic formulations. From a safety point of view, the early detection of biological contaminations by the detection of structural instabilities (of changes) within emulsions could represent a major advance during the production and marketing phases of cosmetic products

Der volle Inhalt der QuelleTitanium dioxide, the most commonly used mineral compound in cosmetic sunscreen products, has recently been incorporated in the form of nanoparticles, which raises health issues. We have developed a protocol of oil-in-water emulsions that enables the incorporation of different amount (2.5-10%) of TiO2 nanoparticles coated with two distinct hydrophobic surface treatments: an isopropyl titanium triisostearate / triethoxycaprylylsilane hybrid coating and a triethoxycaprylylsilane coating. The incorporation of nanoparticles preserves the microscopic structure of the emulsion while enhancing the rheological properties. Physico-chemical analyses showed that the initial state of flocculation of the emulsions is coating-dependant. At 50°C, emulsions destabilize over time until a strong aggregation of nanoparticles, in a delayed way for the hybrid coating. Formulations with and without nanoparticles appear slightly cytotoxic, with an enhanced effect for high amount of TiO2 and for a 40 days aging at high temperatures. We have shown that the surface of nanoparticles extracted from the formulations has been modified during aging, due to an adsorption of chemicals of the emulsion to the nanoparticle surface. Such modified nanoparticles become more cytotoxic if compared to raw nanoparticles. Aging mechanisms can therefore release nanomaterials residues with an increased toxic activity compared to their initial state, and thus could lead to health hazard for humans and for the environment

Der volle Inhalt der QuelleThe design of optimal mixtures is a major challenge in many industrial sectors, especially for formulated products such as cosmetics. Due to the large number of different combinations of ingredients and their quantities, a critical issue is how to define a narrow search space using available knowledge. For this purpose, besides considering some key physicochemical properties of the final product, it is of paramount importance to take into account the performance of the product as perceived by the final consumer. Here, we have proposed a methodology to find a set of plausible formulations for emulsified cosmetic products, based on a fuzzy integral analysis of the consumer preferences and integrated into a mixed-integer optimization tool that incorporates available heuristic rules and property models. Two case studies of cosmetic emulsions were given to illustrate the methodology. In a first example using hair conditioners, the rheological, textural, and microstructural properties of nine alternative formulations manufactured at a lab scale were measured to validate the modelling of emulsified products. Then, two commercial samples of skin moisturizers were tested to identify the most relevant consumer attributes using fuzzy measures. Based on this assessment, ten computer-generated solutions with minimum ingredient costs were also manufactured and evaluated, showing that the proposed methodology could be well adapted to accelerate reformulation or benchmarking processes. Using this approach, product designers could also estimate the relevance and interactions of subjective consumer attributes and guide the design of other formulated products

Der volle Inhalt der QuelleEmulsions play a major role in cosmetology. Given the new European standards, manufacturers will be compelled to provide more information on the products, in particular on their compositions, their toxicity and their expected lifetime. They will have to be able to assess the degradation through protocols of accelerated ageing and suitable analytical tools. Accordingly, the emulsions studied, were stored over a long-term duration at various temperatures to accelerate the ageing process and to evaluate the stability of cosmetic emulsions. Their evolution was followed by various classical analytical techniques: spectroscopy FTIR, rheology, microscopy, conductimetry, texture analysis. . . . Spectroscopy IRTF, using structural indices, revealed new species resulting from the oxidation (identified by deconvolution) and oxidation mechanisms are proposed. The rheological measurements, carried out at the same time, have a predictive aspect since modifications of the rheological parameters are detected for stable emulsions with the naked eye and for which no chemical modification is measured. Moreover these two techniques made it possible to highlight the influence of the nature of oil and of the emulsifier on the stability of the emulsions. Thus, they will ease the choice of additives
