New multifunctional hydrotropic surfactants with excellent performance / Alexander T. Wagner in SOFW JOURNAL, Vol. 142, N° 10 (10/2016)  

[article]  inSOFW JOURNAL > Vol. 142, N° 10 (10/2016) . - p. 4-8 Titre : New multifunctional hydrotropic surfactants with excellent performance Type de document : texte imprimé Auteurs : Alexander T. Wagner, Auteur ; Armin Bach, Auteur ; Stefanie Wehler, Auteur Année de publication : 2016 Article en page(s) : p. 4-8 Langues : Anglais (eng) Catégories : Anticorrosion Composés hydrotropes Emulsifiants Formulation (Génie chimique) Surfactants Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Nowadays raw materials for cleaner formulations not only have to perform well, but also are expected to have additional benefits. For example, the water-solubility of sparingly soluble nonionic surfactants in alkaline formulations can be enhanced by adding classical hydrotropes. On the other hand, to generate an additional value — a higher cleaning performance — these hydrotropes must be replaced by hydrotropic surfactants. Two new developments from ZSCHIMMER & SCHWARZ — ZUSOTEC SE 300 and ZUSOTEC CP 160 — are excellent hydrotropic surfactants with even more benefits (multifunctionality). ZUSOTEC SE 300 is based completely on renewable raw material and a powerful emulsifier for oils of different polarity. ZUSOTEC CP 160 is an outstanding anti-corrosion agent in acidic formulations.

Surfactants with strong anti-corrosion properties / Armin Bach in SOFW JOURNAL, Vol. 144, N° 4 (04/2018)  

[article]  inSOFW JOURNAL > Vol. 144, N° 4 (04/2018) . - p. 58-62 Titre : Surfactants with strong anti-corrosion properties Type de document : texte imprimé Auteurs : Armin Bach, Auteur ; Alexander T. Wagner, Auteur ; Stefanie Wehler, Auteur Année de publication : 2018 Article en page(s) : p. 58-62 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Anticorrosion Surfactants Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Metals played a key role in the history of mankind ever since. The naming of special periods in history (e.g. the bronze age, the iron age) reflects this high importance. In modern society metals are still very important. A serious challenge with regard to metals is the damage by corrosion, particularly when metals get into contact with strong acids or alkalis which are often used in professional metal cleaning processes. Hence, the protection of metals is strongly recommended.

A tailor-made approach to grant wishes / Stefanie Wehler in SOFW JOURNAL, Vol. 145, N° 10 (10/2019)  

[article]  inSOFW JOURNAL > Vol. 145, N° 10 (10/2019) . - p. 12-16 Titre : A tailor-made approach to grant wishes Type de document : texte imprimé Auteurs : Stefanie Wehler, Auteur Année de publication : 2019 Article en page(s) : p. 12-16 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Coût -- Contrôle Détergents Développement durable Emballages Formulation (Génie chimique) Ligands Polymères Produits nettoyants Savon Surfactants Transport Index. décimale : 668.5 Parfums et cosmétiques Résumé : The term "sustainability" already exists for a long time, but only now the consumer’s demand for sustainable concepts and products is strongly rising. Detergents and cleaning agents are one of many involved product groups. However, since other requirements as cleaning performance and price must also be met, a sustainable cleaner is not simply the result of using natural raw materials. The overall package must match. At our 125th anniversary, we from Zschimmer & Schwarz not only look back on many years of experience, but are also committed to a sustainable future. As a manufacturer of specialties regarding surfactants, complexing agents and polymers, we offer support and ideas to fulfil a wide range of consumer wishes – in other words: a tailor-made approach to grant wishes.
