Walnut shells as ingredients for cosmetics

Search for alternatives to microplastics

12-Dec-2023 - Banned throughout the EU since October 2023: Microplastics in all cosmetic products and detergents. But what alternatives are there? Researchers at Rhine-Waal University of Applied Sciences (HSRW) want to find out together with the family-run company bb med. product GmbH from the Lower Rhine ...

Repellant and Hostile to Bacteria

Zwitterionic polymeric sulfur ylides: antifouling coating with a synergistic effect

13-Sep-2023 - Bacteria that gather into biofilms on the surfaces of implants, catheters, breathing tubes, and other medical components are a serious health hazard. In the journal Angewandte Chemie, a research team from the Netherlands has now introduced a new material based on poly(sulfur ylides) that—when ...

Plastics could see a second life as biodegradable surfactants

A new chemical process provides biodegradable chemicals

30-Apr-2021 - Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of applications, from ...

A splash of detergent makes catalytic compounds more powerful

05-Jun-2018 - Researcher David Rosenberg examines images of a white powder under a powerful scanning electron microscope. Up close, the powder looks like coarse gravel, a heap of similar but irregular chunks. Then he looks at a second image — the same material produced by colleague Hongyou Fan instead of ...

Multiresponsive nanosurfactant constructs tiny chemical factory

12-Jan-2018 - When people hear of surfactants, they normally think of a static chemical compound used to stabilize droplets in the manufacture of soaps, detergents, or paints. Research has shown that active forms of surfactants can respond to individual external stimuli, but what if it could interact with more ...

Universal stabilization

Microparticles with a rough, raspberry-like surface stabilise emulsions following a new principle

16-Jun-2017 - Researchers led by Lucio Isa, Professor of Interfaces, Soft Matter and Assembly at ETH Zurich's Department of Materials, have created a new type of silica particle able to stabilise emulsions in a new way. An emulsion is a finely dispersed mixture of two immiscible liquids, constituted by ...

Clean growth: Ceresana publishes second market report on surfactants

10-Apr-2015 - Surfactants facilitate the removal of dirt and enable to finely mix water and oil. These surface active chemical substances are used in every household but also serve for numerous industrial applications. "In 2014, a worldwide turnover of 33.2 billion US$ was achieved with surfactants" says ...

Ceresana expects the market for bioplastics to grow

05-Feb-2014 - Even though they still account for only a small share of the plastics market as a whole, bioplastics have become a real alternative to standard plastics manufactured from petrochemical feedstocks. The term 'bioplastics' is utilized for a whole range of various products with different properties ...
