One is a new concept, included in the packaging to be released in the cosmetic products it contains. The second one is an antibacterial substance, for which there is a request to use as a preservative. A request for opinion has just been sent the SCCS for these two substances.
EcoG+
Background
The proposed new preservative "EcoG+" is silver-containing phosphate glass, a powder consisting of small glass beads, "EcoG+" is intended to be mixed with glass beads and an appropriate polymer and used to manufacture composite materials for cosmetic product packaging. The substance intended to be released into the cosmetic product is the silver ion. "EcoG+" therefore acts as an inert carrier, into which the silver ion is dispersed.
"EcoG+" is mixed with glass beads and a suitable polymer to form a composite packaging material. A proportion of the glass matrix remains at the surface of the material. The achieved level of the active component (i.e. silver) in "EcoG+" is 2%; the proportion of "EcoG+" envisaged for use in the packaging material is 3%. On use of the composite material as cosmetic product packaging, small amounts of silver ions are released into the cosmetic product, where it is intended to have a preservative function.
The typical use of "EcoG+" is envisaged to be a level of 1.4-2.0% in cosmetics packaging. The maximum achieved level of silver ion in "EcoG+" is 2%, therefore the maximum achieved level of silver present in the cosmetic packaging material is 420-600 ppm.
