A raw material from an unexpected source

The thin membrane inside an eggshell is hardly the first thing that comes to mind as a cosmetic ingredient. Yet this is the material at the centre of Eggnovo’s work. The company specialises in recovering and adding value to eggshell membrane. Reschem Italia has started a collaboration to introduce RejuveColl™—an ingredient originating from this supply chain—to Italian formulators.

The story of its origin is interesting. But for anyone developing creams and treatments, the source alone is not enough: they also need to know what the material contains, how it behaves in a formulation and which results can be substantiated.

What does eggshell membrane contain?

According to information shared by Eggnovo, eggshell membrane naturally contains components including collagen, elastin and hyaluronic acid. The partner positions RejuveColl™ for skin care applications, including formulations exploring ingredients obtained by making use of by-products.

The presence of these components does not automatically mean that a finished cream delivers a proven benefit. Any performance claims require supporting evidence, testing and appropriate regulatory assessment.

From the concept to laboratory testing

Anyone evaluating RejuveColl™ will need to consider formulation compatibility, stability, concentrations and sensory properties. The collaboration between Reschem and Eggnovo allows laboratories to discuss these aspects with support from both distributor and manufacturer.
