Merck unveils “metallic allure” Ronaflux pigments at In-Cosmetics 2023
27 Mar 2023 --- Science and technology company Merck is presenting its latest cosmetics innovations at this year’s in-cosmetics Global trade show, which PersonalCareInsights is reporting live from on March 28-30 in Barcelona, Spain.
The company is spotlighting its cosmetic actives sourced from ocean algae for skin renewal alongside “next generation” sunscreen ingredients. It will also present its Ronaflux pigment range that features high color intensity and pronounced metallic optical effects achieved entirely without the use of metals.
“A striking, color-intense look with a metallic allure reflects the current popular trend in color cosmetics. At the same time, it’s necessary for manufacturers to meet stricter regulatory requirements and to ensure the stability of the colorants and pigments,” comments Michael Weiden, head of Commercial EMEA within the Surface Solutions business unit of the Electronics business sector of Merck.
“With our Ronaflux pigments, which are based on an entirely new technology, our customers can meet these challenges while achieving unique effects that are not yet commercially available.”
The technology behind Ronaflux pigments is branded “sophisticated and simple.” Ultrathin and highly stable carbon layers are homogeneously precipitated in a gas phase onto the pigments – a major precondition for spectacular shine effects.
The carbon layers intensify the colors of the effect pigments, thus making brilliant shades of blue and green possible without the addition of chrome oxides, Prussian blue or other colorants.
This enables manufacturers of eye makeup and lipsticks to meet the strict regulatory requirements while offering brilliant, metallic blue and green shades that do not contain any metal-based pigments.
Zinc oxide-UV filters for a new generation of sunscreens
Addressing the growing market for environmentally sound and pure mineral sunscreens, Merck will also be showcasing its newly expanded UV filter portfolio with the addition of Eusolex Z-BASE and Eusolex Z-TEC, zinc oxide filters that offer highly effective protection against both UVB and UVA rays.
Eusolex Z-TEC is extremely transparent on the skin even in high concentration formulations such as pure mineral high-SPF sunscreens.
The products are approved in accordance with the COSMOS standard and are Halal-certified.
Algae-based cosmetic actives from the ocean
Two new additions to the Merck’s algae-based skin renewal portfolio will also be presented.
RonaCare JouvaMer and RonaCare ReviMer have been developed from brown seaweed from the coast of Brittany in France.
RonaCare JouvaMer, an extract of Pelvetia canaliculata brown algae, is an anti-aging booster that reduces wrinkles by stimulating collagen synthesis. In addition, it protects and supports the extracellular matrix for denser, smoother skin.
RonaCare ReviMer, an extract of Fucus serratus brown algae, shows preventive anti-pollution effects while enhancing the skin’s structural properties. It also protects the skin’s hyaluronic acid for firmer, more elastic skin, thus reducing wrinkles.
RonaCare JouvaMer and RonaCare ReviMer can be used in a wide variety of topical products ranging from daily skincare to dermocosmetics, highlights the company. Together with RonaCare RenouMer, which has already been launched, they complete the Merck offering for algae-based skin renewal.
All products in this category are designed to meet the current requirements as regards sustainability, traceability and respect for biodiversity. The products are halal-certified and comply with the COSMOS standard.
Along with its RonaFlair portfolio of functional fillers, Merck is also presenting alternatives to talc, an ingredient commonly used to date in skincare products that suppliers are increasingly looking to replace.
Starting tomorrow, PersonalCareInsights will be reporting live from the in-cosmetics show floor in Barcelona.
