- [Fettalkohole in der Haarpflege: Chemie, Emollient\-Mechanismus und Professionelle Formulierung](https://www.hairswiss.ch/de/4956): Fettalkohole — Cetearyl Alcohol, Cetyl Alcohol, Stearyl Alcohol, Behentrimonium Methosulfate — sind langkettige Alkohole \(C16–C22\) ohne austrocknende Wirkung, grundlegend in der Formulierung professioneller Balsame und Masken\. Hairswiss analysiert ihre Molekularchemie, den Kutikulaglättungsmechanismus und ihre Rolle als Co\-Emulgatoren und Faserconditioner\.
- [Alcoli Grassi Capillari: Chimica, Meccanismo Emolliente e Ruolo in Formulazione Professionale](https://www.hairswiss.ch/it/4955): Gli alcoli grassi — Cetearyl Alcohol, Cetyl Alcohol, Stearyl Alcohol, Behentrimonium Methosulfate — sono alcoli a lunga catena carboniosa \(C16–C22\) senza effetto essiccante, fondamentali nella formulazione di balsami e maschere professionali\. Hairswiss analizza la loro chimica molecolare, il meccanismo di levigatura cuticolare e il ruolo come co\-emulsionanti e condizionanti della fibra capillare\.
- [Alcools Gras Capillaires : Chimie, Mécanisme Émollient et Rôle en Formulation Professionnelle](https://www.hairswiss.ch/fr/4954): Les alcools gras — Cetearyl Alcohol, Cetyl Alcohol, Stearyl Alcohol, Behentrimonium Methosulfate — sont des alcools à longue chaîne carbonée \(C16 à C22\) sans effet desséchant, fondamentaux en formulation des après\-shampooings et masques professionnels\. Hairswiss analyse leur chimie moléculaire, leur mécanisme de lissage cuticulaire et leur rôle comme co\-émulsifiants et conditionneurs de la fibre capillaire\.
- [Dimethicone in Hair Care: Chemistry of Heavy Silicones, Deposition Mechanism and Professional Use](https://www.hairswiss.ch/en/4832): Dimethicone is a linear polydimethylsiloxane \(PDMS\) whose viscosity — expressed in centistokes \(cSt\) — directly determines its behavior on the hair fiber: light fractions \(50–200 cSt\) partially penetrate the cuticle; heavy fractions \(\>1,000 cSt\) form an occlusive surface film\. Hairswiss analyzes its molecular chemistry, deposition mechanism and the controversies surrounding accumulation on the fiber\.
- [Fatty Alcohols in Hair Care: Chemistry, Emollient Mechanism and INCI Guide](https://www.hairswiss.ch/en/4458): Fatty alcohols \(cetyl, stearyl, cetearyl C16–C18\) are structurally distinct from ethyl alcohol: their long aliphatic chain gives them emollient, emulsion\-stabilizing, and occlusive properties on the hair fiber\. Hairswiss analyzes their molecular mechanism of action and explains how to correctly identify them on an INCI list\.
