Langues : Anglais (eng) Catégories : Composés inorganiques Cosmétiques Déodorants Diatomées Humidité -- Absorption Matériaux poreux Odeurs -- Lutte contre Olfactométrie Index. décimale : 668.5 Parfums et cosmétiques Résumé : The present study examines the performances of an new, ultra-absorbent, natural diatomaceous earth for deodorants. This innovative mineral is evaluated through water and oil absorption tests, user tests (roll-on formulations tested by 33 panelists) and odor tests (odor intensity and olfactometric analysis with synthetic perspiration). It has been demonstrated that this new, highly absorbent, diatomaceous earth prevents unwanted moisture and keeps the underarms dry. Moreover, this diatomaceous earth demonstrates the capacity to effectively capture volatile synthetic perspiration odor molecules. finally, this 100% natural mineral combines excellent sweat and odor absorption properties.

Natural ingredients for providing opacity and pearlescence in shower gels and shampoos / Laure Pagis in SOFW JOURNAL, Vol. 144, N° 6 (06/2018)  

[article]  inSOFW JOURNAL > Vol. 144, N° 6 (06/2018) . - p. 2-4 Titre : Natural ingredients for providing opacity and pearlescence in shower gels and shampoos Type de document : texte imprimé Auteurs : Laure Pagis, Auteur ; H. Leroy, Auteur ; F. Jouffret, Auteur Année de publication : 2018 Article en page(s) : p. 2-4 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Cheveux -- Soins et hygiène Cosmétiques Cosmétiques -- Suppression ou remplacement Kaolin Opacité (optique) Peau -- Nettoyage Peau -- Soins et hygiène Produits chimiques -- Suppression ou remplacement Produits naturels shampooings Talc Index. décimale : 668.5 Parfums et cosmétiques Résumé : Opacifiers and pearlising agents are widely used to improve the appearance of shower gels and shampoos. Most current opacifying and pearlising solutions are based on synthetic ingredients, such as : styrene/acrylate copolymers for opacifiers, glycol stearate derivatives with fatty amides or mica-coated with a high refractive index metal oxide coating for pearlising agents. These synthetic ingredients are in the line of fire due to current trends towards zero-plastic and zero-nano particle products. Beides, they can also be difficult to use due to pH restrictions, need for high-temperature processes, and compatibility issues with other ingredients, particularly with cationics. This study demonstrates that a specific natural kaolin-based solution can be used to replace synthetic opacifiers and a specific natural talc-based solution can replace conventional pearlising agents. Note de contenu : - METHODS : Formulations - Instrumental test : colour measurements - Instrumental test : opacity measurements - Panel test : pearlescence intensity measurements - RESULTS : A new kaolinite mineral to replace synthetic opacifiers - An innovative talc mineral to replace pearlizing agents - DISCUSSION : The innovative kaolin imparts opacity and whiteness thanks to its unique porous morphology - The talc-based talc pearlising agents imparts pearlescence thanks to controlled lamellarty - Table 1 : Composition of shower gel formulation usef for characterization tests - Table 2 : Opacity and whiteness of 0.75 % innovative kaolin opacifier compared to opacity of 0.75 % conventional kaolin - Fig. 1 : Opacity of an innovative kaolin-based opacifier compared to an oil-derived opacifier in a shower gel formulation - Fig. 2 : Optical effect of 0.75% innovative kaolin-based opacifier in a clear gel formulation - Fig. 3 : Pearlising effect of two formulations measured by a volunteer panel test - Fig. 4 : The new kaolin-based solution has a different morphology from conventional kaolin - Fig. 5 : Compared to conventional talc the new talc-based solution has controlled multi-sheet thickness En ligne : https://drive.google.com/file/d/1qve78Cv3_d1gxB7aWC3wp5To6hdvsSAH/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30734 [article]
