ImerCare Blur a sustainable alternative to synthetic ingredients

Imerys has designed a unique patented calcium carbonate with a specific size, spherical morphology and transparency which is an effective natural alternative to synthetic  ingredients, such as silica, Polymethyl Methacrylate (PMMA) and nylon, used as skin mattifying agents in make-up and cosmetics.

ImerCare Blur meets current trends for sustainable ingredients which improve the ecoprofile of the end product, comply with changing regulations - such as the ban on microplastics - and meet increasing consumer demand for natural products.

Due to its unique spherical morphology which creates a ‘ball bearing’ effect, ImerCare Blur improves the smoothness and sensory profile of cosmetics, whilst creating a soft focus effect which diminishes imperfections and reduces fine lines and wrinkles.

ImerCare Blur demonstrates similar performance to silica, nylon and PMMA

In panel tests comparing ImerCare Blur to silica, nylon and PMMA in pressed powder formulations, ImerCare Blur delivered equivalent performance to synthetic ingredients in terms of soft focus, opacity, matt effect and adherence.

ImerCareBlur has a transparent life-cycle and is Cosmos-approved

Imerys is committed to finding innovative solutions that enable its customers to align with sustainability-related trends and regulations. 

Imerys has conducted numerous Life Cycle Assessments (LCA) of the products in its portfolio to determine their environmental footprint. These studies provide customers with fully comprehensive, transparent information about a product and give more visibility on the impact of specific products or facilities—a prerequisite to any eco-design approach.

ImerCare Blur is produced at our Salin de Giraud site in France which is covered by 14001 environmental management and ISO 50001 energy management certification and which has been widely engaged in cultivating good neighbour relations through initiatives such as shared gardens, ecograzing for local livestock and renewable electricity projects.

The full LCA of ImerCare Blur, calculated according to ISO 14040 and 14044 standards, is available upon request.

ImerCare Blur complies with industry microbiological standards without resorting to irradiation. It is not treated with chemicals during processing. As such, it is Cosmos approved.
