Gomme de xanthaneLa gomme xanthane est un polyoside obtenu à partir de l'action d'une bactérie, la Xanthomonas campestris. Elle est soluble à froid et est utilisée comme additif alimentaire sous le code E415 pour ses propriétés épaississantes et gélifiantes afin de modifier la consistance des aliments.
Le xanthane est l'un des exopolysaccharides excrétés par divers microorganismes du sol (bactéries notamment). Il joue un rôle important, à l'échelle moléculaire, dans la formation et la conservation des sols3, tout comme le dextrane, le rhamsane ou les succinoglycanes.
Gomme gellaneLa gomme gellane (E418) est un polyoside extracellulaire d'origine microbienne. C’est un gélifiant utilisé en agro-alimentaire. La gomme gellane est produite par la bactérie Sphingomonas elodea (ex Pseudomonas elodea), qui se développe naturellement sur des plantes aquatiques appelées élodées. (Wikipedia)

RhéologieIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Using the findings from previous sensory research projects on predictive models, the current paper analyses whether, and how, the functional properties of acrylates can be imitated in cosmetic emulsions using biopolymers. It could be established that at a suitable concentration, a combination of two natural substances produced using biotechnology – gellan gum and xanthan gum – can replace an acrylic acid polymers and deliver the desired sensory properties and in some cases also the stabilisation. By taking rheological measurements in oscillation mode, a correlation to the sensory attribute of body could be established via the storage modulus G' and the plateau value. The quick break attribute also proved useful in evaluating a polyacrylate imitation. The measurement data of the rheology spectrum helped to establish the biopolymer combinations that were most similar to the polyacrylate. An after-sun cream-gel formulation was used to demonstrate that even a trained panel of sensory experts could not establish any significant sensory difference between the acrylate and gellan gum formulations.

Produits de beauté masculinsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Against a background of increasing interest in expanding the male cosmetic market sector and concerns about adequate sun protection, the sensoriel product characteristics of various facial skin care and sun protection products that are currently on the market were analyzed. The objective of the study was to identify those characteristics that significantly affect product preference in a male target group.
The sensoriel product characteristics that have A positive or negative influence on overall product preference were determined by means of a consumer survey and sensory methods, including acceptance tests among male consumers and objective profiling by a trained panel at the Zurich University of Applied Sciences (ZHAW), Switzerland, The influence of positive sensory product properties which affect consumer preference, such as absorption, spreadability, softness and fresh/cooling effect, was masked if negative sensory product characteristics such as whitening, stickiness and product residue were perceived by the consumer. The study provides evidence that the overall popularity of cosmetic products is measurable and that sensory analysis data combined with "External Preference Mapping" can provide a meaningful, objective, comprehensible and visuel representation of consumer preferences. Sensory analysis comprises the only link between a product briefing from the marketing department and the corresponding product formulation on the one hand and the expectations and aspirations of the consumer on the other.Note de contenu : - EXPERIMENTAL METHOD : Research method (sensory acceptance test - sensory profiling)
