Because we cannot control the source of recycled materials, the use of PCR can make it difficult to perfectly control the color of packaging and to achieve bright colors. PCR material is typically dark gray, making it hard to achieve Maybelline’s traditional bright colors.   The color of the packaging does not remain consistent given the materials that make up the recycled streams, e.g., the colors of recycled plastic bottles. Additionally, there is an increase in inclusions with PCR materials.  Inclusions are black dots / particles in the material.  This is due to the variety of recycled material included in the packs. For example, if there is a black dot on your foundation cap, it is not a dirt mark – it is a mixture of different recycled content.
