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. Ingrédients cosmétiques Produits naturels Index. décimale : 668.5 Parfums et cosmétiques Résumé : Rheocare XGN is the first polymer launched by BASF based on purely vegan xanthan gum. It is 100-percent produced using renewable feedstock and no genetically modified organisms(GMO). As a powerful thickening agent and stabilizer for emulsions and surfactant-based formulations, this highly flexible polysaccharide can be used in various cosmetic applications, even oral care. It creates crystal-clear formulations, has a high electrolyte and ethanol tolerance, can be processed cold, and is easy to use - even without neutralization. Rheocare XGN is also COSMOS-approved and suitable for NATURE formulations.

Hyaluronic acid – an extraordinarily versatile vital substance / Henry Häusler in SOFW JOURNAL, Vol. 144, N° 11 (11/2018)  

[article]  inSOFW JOURNAL > Vol. 144, N° 11 (11/2018) . - p. 8-10 Titre : Hyaluronic acid – an extraordinarily versatile vital substance Type de document : texte imprimé Auteurs : Henry Häusler, Auteur Année de publication : 2018 Article en page(s) : p. 8-10 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Antiâge Hyaluronique, acide L'acide hyaluronique est un type de polysaccharide (plus précisément une glycosaminoglycane) non fixé à une protéine centrale et largement réparti parmi les tissus conjonctifs, épithéliaux et nerveux animaux. Il se trouve notamment dans l'humeur vitrée et le liquide synovial. Il est l'un des principaux composants de la matrice extracellulaire ainsi que de certaines mucoprotéines lorsqu'il est associé à une fraction protéique. Depuis les années 1990, il est très utilisé dans divers dispositifs médicaux, médicamenteux et cosmétiques (présenté dans ce dernier cas comme "antistatique, humectant, hydratant, conditionneur cutané, anti-âge, etc."), bénéficiant d'un effet de mode grandement soutenu par une large publicité commerciale. Contribuant de façon significative à la prolifération et à la migration des cellules, l'acide hyaluronique est aussi impliqué dans la progression de certains cancers.

Life cycle assessment (LCA) of naturally-sourced and petroleum-based glycols commonly used in personal care products / Rachel Pacheco in SOFW JOURNAL, Vol. 144, N° 11 (11/2018)  

[article]  inSOFW JOURNAL > Vol. 144, N° 11 (11/2018) . - p. 12-16 Titre : Life cycle assessment (LCA) of naturally-sourced and petroleum-based glycols commonly used in personal care products Type de document : texte imprimé Auteurs : Rachel Pacheco, Auteur ; Kyle Huston, Auteur Année de publication : 2018 Article en page(s) : p. 12-16 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Durée de vie (Ingénierie) Glycols Un glycol ou diol est un composé chimique organique portant deux groupes hydroxyle (-OH). Lorsque les deux groupes hydroxyle sont portés par le même atome de carbone, on parle de diol géminal. Parmi ceux-ci, on compte par exemple le méthanediol (H2C(OH)2) ou le 1,1,1,3,3,3-hexafluoropropane-2,2-diol ((F3C)2C(OH)2), la forme hydratée de l'hexafluoroacétone. On parle de diol vicinal lorsque les deux groupes hydroxyle sont en position vicinale, c'est-à-dire attachés à des atomes de carbone adjacents. On compte parmi ceux-ci l'éthane-1,2-diol ou éthylène glycol (HO-(CH2)2-OH), un composant courant des produits antigels ou le propane-1,2-diol (propylène glycol, HO-CH2-CH(OH)-CH3). Parmi les composés avec des groupes hydroxyles bien plus éloignés on compte le butane-1,4-diol (HO-(CH2)4-OH) ou encore le bisphénol A. Ingrédients cosmétiques Produits naturels Produits pétrochimiques Index. décimale : 668.5 Parfums et cosmétiques Résumé : Glycols, including 1,3-butylene glycol (1,3-BG), play an important role in the development of personal care products, including creams, sunscreens, shampoos, body washes and more. As concern about petroleum-based ingredients continues to grow, consumers have become increasingly concerned about the ingredient sources and manufacturing processes involved with making their products, including consideration of ingredient's lifecycle impact and overall natural and sustainability attributes. To adress these concerns, Genomatica has conducted a systematic study, called a life cycle assessment (LCA), on the environmental impact of the produtcion process they've developed for their naturally-sourced, bio-based 1,3-BG (known as Brontide), as compared with a petroleum-based alternative. The results show that conventional1,3-BG production processes starting from petroleum-based feedstocks have a significanly higher global potential and energy demand from renewable plant-based feedstocks. The results of this study will help personal care and cosmetic's formulators choose ingredients that have a reduced environmental impact while also addressing their customer's increasing desire for more natural products, helping manufacturers work toward a more sustainable future.

Recommendation for the quality assessment of paint care products for motor vehicles / The German Cosmetic, Toiletry, Perfumery and Detergent Association (IKW) (Mainzer Landstraße 55, 60329 Frankfurt am Main, Germany) in SOFW JOURNAL, Vol. 144, N° 11 (11/2018)

Langues : Anglais (eng) Catégories : Automobiles -- Revêtements:Automobiles -- Peinture Essais (technologie) Evaluation Nettoyage Produits nettoyants Index. décimale : 668.5 Parfums et cosmétiques Résumé : IKW member companies make their expert knowledge products they manufacture available to the general pur is done in the form of quality assessment recommende The recommendations for the quality assessment rated in working groups and are intended to enable fied testing of the relevant products by the manufacturers institutes. Quality characteristics are described that need test to be fulfilled by the products concerned in order to a the effects expected by consumers and manufacturers. The companies working within the framework of In optimal quality standards for their products. Their aim is a consistent orientation to sustainability as a guiding P ple, preparing to successfully face the future in a consta changing world. This commitment to sustainability as a guiding principle built up on experiences expressed in numerous exemplary initiatives. Taking as starting points the declarations of Rio 1992, "92 plus 10" of Johannesburg and the Agenda 21, sustain ability is understood as a balanced linking of economic, social and ecological aspects, with a view to meeting the needs o the present without compromising the ability of future generations to meet their own needs. With this in mind, quality assessment recommendations have to encourage company staff to act responsibly toward humans and the environment in product development and manufacture. They also serve consumers who can expect efficient, safe and environmentally sound products. The recommendations describe which qualities are relevant to a given product and how such qualities can be measured. It should be noted that every finished product has a certain efficacy spectrum in its intended use; this spectrum is largely determined by consumer expectations as to each individual quality characteristic - so that in each product some characteristics are deliberately emphasised while others will be less important. Moreover, the desired combination of product properties is subject to constant change, depending on the latest technical possibilities and new consumer habits. Quality assessment recommendations must not impair such developments. Consequently, for each product only one overall result is valid to determine whether the product meets the quality recommendations or not. Emphasis on isolated test criteria is not admissible and may be misleading.
