Evonik to make industrial- scale biosurfactants
Evonik has announced that it is to build the world’s first industrial-scale facility for rhamnolipid biosurfactants at its site in Slovenská Ľupča, Slovakia. Construction is scheduled for completion by the end of 2023 and the company described this as a triple-digit million-euro investment. The plant will use the
biotechnology platform of Evonik’s Nutrition & Care business to make the rhamnolipids via a fermentation process using sugar as the main raw material. The company has already entered into a strategic supply partnership with Unilever to make new hand
dishwashing detergent using them. “Rhamnolipids are fully
biodegradable and their low- impact life cycle means they are a sustainable alternative to conventional surfactants,” Evonik
said. “Their exceptional foam- forming properties make them suitable for use in household cleaners and personal care products like shampoos and micellar waters.”
BASF plans UVA filter plant
BASF Care Chemicals has announced plans to build a 1,500 tonnes/year plant to make its Uvinul A Plus brand of UVA filters at Jinshan, China, in addition to existing production at its largest site at Ludwigshafen in Germany. This should come onstream in 1H 2023. Uvinul A Plus is claimed to
be “one of the few photostable UVA filters available in the market today that reliably filters the sun’s harmful UVA rays and
provides protection from free radicals and skin damage”. It comes in a preservative-free, oil- soluble granule form for optimal formulation flexibility. “This investment underlines
BASF’s commitment to the region and our customers,” said Dr. Rajan Venkatesh, SVP of Care Chemicals at BASF Asia Pacific. The company already produces Tinosorb S broad-spectrum UV filters at the site in Kaohsiung, Taiwan.

Biesterfeld in JRS deal
Biesterfeld Spezialchemie has become the exclusive distributor of bio-based and biodegradable cellulose raw materials of J. Rettenmaier & Söhne (JRS) for personal care in Germany. “Technology-based
consulting and expertise in cosmetic formulations is especially in demand when it comes to replacing raw ingredients,” said Harald Schlosser, global head of the Home & Personal Care business unit at JRS, when explaining why Biesterfeld was chosen. The agreement covers
JRS’s new portfolio of natural, sustainable and biodegradable plant- and ocean-based ingredients, which are primarily used in formulations for hair, skin and sun care products, as well as hygiene products, decorative cosmetics and oral hygiene. The ingredients are extracted
from wood, bamboo, apples, oats, oranges, maize, potatoes and brown algae, using chemical and mechanical methods. They are 100% natural and have applications including rheology modifiers, exfoliants or to enhance the sensory profile of a formulation.
Bitop actives protect microbiome, company says
Bitop has performed new efficacy studies on its extremolytes, Ectoin Natural (INCI: Ectoin) and Glycoin Natural (INCI: Glyceryl Glucoside). It found that both protect the viability of the skin microbiome, while also offering blue light protection. Four bacterial strains
representing a large percentage of the microbiome were incubated with the two actives and their viability and growth were measured afterward. Both actives not only had no negative impact on the microbiome but maintained its viability. Glycoin Natural “even enhances bacterial growth at a low percentage of usage, thus a

prebiotic effect can be claimed”, Bitop stated. In an in vitro study, both actives
“showed powerful protection properties on a cellular level”, the company said. In addition to the proven protection efficacy of Ectoin Natural against blue light-induced oxidative stress and pigmentation, this proved its efficacy in protecting skin cells from blue light-induced DNA damage. This study was also the first time that Glycoin Natural was proven to have such efficacy. It boosts the expression of Aquaporin 3 (AQP3) in keratinocytes, when the skin is exposed to blue light, maintaining their natural level.
