The Royal Society of Chemistry, in partnership with the SCS (Society of Cosmetic Scientists) have recently published an authoritative new book: Discovering Cosmetic Science.

Discovering Cosmetic Science - Front CoverThe 450+ page book helps to explain the amazing science behind the development of cosmetic formulations for those considering a career in cosmetic science, those new to the industry or even the old hands amongst us who simply want to refresh their knowledge.

Discovering Cosmetic Science takes a deep dive into the cosmetic world, capturing an in depth look at the beauty and personal care products that most of us use every day. From hair care to oral care, skincare to makeup, and not forgetting fragrances, this book answers the many questions we have such as:

  • What makes surfactants so special?
  • Are there differences between men and women’s skin?
  • What messages are carried by fragrances?

Testing and more Testing

XCellR8 were delighted to be asked to contribute images of work carried out in our lab for the chapter “Testing and more Testing”, which focuses on the safety testing of ingredients and finished products. Dr Carol Treasure, CEO of XCellR8, commented “we are proud that a book of this stature has used images of work in our lab to show the gold-standard of animal-free testing”. As a GLP accredited lab, we are meticulous about scientific rigour and have been asked to be an example of good practice before, which is what makes us confident in our abilities to provide reliable information for this book.

Author Stephen Kirk examines some of the key safety considerations needed to bring a product to market. He describes stability testing in great detail, focussing on each step in the process. Microbiological testing, chemical stability and PAO and shelf life of products are all covered, offering a reminder of the complexity of safety testing and why it is so important.

Animal-free in vitro on the rise

Stephen explains in a user-friendly manner how to assess the likelihood of your product causing you any harm and much to our delight, includes information on the latest non-animal technologies. He explains that despite not all areas of cosmetic testing being covered by animal-free in vitro techniques, the most important ones such as irritation and allergic reactions to the skin and eyes and genotoxicity, have been developed and are officially endorsed.

Stephen also delves into the grey-areas surrounding hypoallergenic claims on products. The EU, clearly at the forefront of improving standards for the safety of cosmetics, offers guidance to manufacturers on hypoallergenic materials whilst products manufactured outside the EU might not follow the same principles.

All in all, we believe Discovering Cosmetic Science is a great read and an ideal gift for younger members of your team. With Christmas fast-approaching, we thoroughly recommend popping it on your Christmas Wishlist – take it from us, you definitely won’t be disappointed!
