Vertellus, a global manufacturer of fine, specialty chemicals and plastic additives, has obtained INCI listing for ZeMac Solutions for use in cosmetics and personal care applications.  The ZeMac Solutions are water-based solutions of ZeMac copolymer technology engineered by Vertellus that are used as high molecular weight surfactants and size regulators in microencapsulation of fragrances, specialty inks and pigments as well as phase change materials (PCMs). These solutions were tested by an independent laboratory and showed no skin irritation. These results, along with other documents, have been recently approved by the Personal Care Products Council and ZeMac Solutions are now listed as “Aqueous solution of ammonium of poly(ethylene-maleate)”.
 
What does INCI stand for? INCI is an international designation for the declaration of the ingredients on the packaging of cosmetics.  INCI names are mandated on the ingredient statement of every consumer personal care product globally. The use of INCI minimizes the language barriers that often hinder consumer understanding and international trade. This INCI listing now opens up new applications for ZeMac Solutions in cosmetics and more broadly in personal care markets.
 
“The unique chemistry of the ZeMac copolymer technology and the high molecular weight of ZeMac E400 enables the polyionic effect. This makes it possible for microencapsulation formulators to obtain precise control of particle size distribution of these capsules, which is critical for applications in specialty inks and for permeation control in fragrances,” says Vertellus’ Global Development Manager for Plastics, Dr. Ashok Adur. “Another benefit in many shell systems such as melamine-formaldehyde is the tougher shell which allows formulators to down-gauge the shell. This enables higher payload of the encapsulant for higher efficiency in applications like phase change materials, resulting in lower net cost,” Dr. Adur added.
 
Vertellus will be discussing the technology and applications for ZeMac in microencapsulation during the 21st Microencapsulation Industrial Convention in Montreal, Quebec, Canada, May 21 to 24, 2018. During the convention, Dr. Adur will present a paper on “Use of ZeMac E400-based solutions for Size Regulation of Microcapsules.” Visit the Vertellus Personal Care Team at in cosmetics global in Amsterdam at booth P141 or NYSCC Suppliers Day in NYC.
