The desire for natural and environmentally friendly cosmetics is becoming ever greater. Today’s modern consumers prefer products that do not require microplastics and plastic packaging but have the same convincing performance as conventional cosmetics. Solid formulations combine these requirements and are becoming more and more popular. The development of a solid foundation by CFF GmbH & Co. KG shows that there is even more room for natural and sustainable developments in the field of colour cosmetics. The developed formulation manages without microplastics and plastic packaging and is comparable to a liquid foundation. The solid foundation was tested in the subsequent assessments for the parameters pay-off, powderiness, tackiness, mattifying and coverage. The results show that microcrystalline cellulose has a positive effect on the sensory profile and texture of the formulation. Microcrystalline cellulose, which is 100 % of plant origin, and supports manufacturers in creating environmentally friendly and future-oriented products, can certainly replace microplastics.
