The safety of Polyethylene has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Polyethylene was safe for use in cosmetics and personal care products.  The Food and Drug Administration (FDA) allows Polyethylene to be used in chewing gum base and includes Polyethylene and modified Polyethylenes on the list of permitted indirect food additives. 

Cospheric's polyethylene microspheres have a lot of applications in cosmetics, personal care and skin care industry. Our cosmetic microspheres are perfectly spherical, completely solid, between 10 and 1000microns in diameter, and can be loaded with up to 40% by weight of pigments and additives. In addition, we can make them have positive or negative surface charge. We can also make the colored microspheres to customer's specification.

Powders and Liquid Concealers:

Unique competitive advantage of Cospheric is that we can make very small fully opaque microspheres.  An opaque microsphere does not allow any light to pass through which means every single particle has maximum hiding power. Our microspheres provide superior coverage with one invisible and feather-light layer - revolutionizing make-up products.

What is opacity and how is opacity measured: When light strikes an interface between two substances, in general some may be reflected, some absorbed, some scattered, and the rest transmitted. An opaque substance transmits very little light, and therefore reflects, scatters, or absorbs most of it. High level of opacity becomes more difficult to achieve for microscopic particles. Cospheric is the only company in the world to manufacture truly opaque microspheres. Colored opaque microspheres are available.

Color Matching Capability:

Creams, Lotions and Cleansers:

Sphericity and particle size uniformity are responsible for the ball-bearing effect in creams and lotions, which imparts the finished product with a silky elegant texture, luxury feel, enhanced slip, glide and omnidirectional spreadability providing a "cream to powder" texture. Outstanding roundness also provides lubrication during application.

Cospheric spherical microparticles are guaranteed to be >90% spherical and within specified particle size range. The exceptional smoothness of Cospheric microspheres dramatically enhances the tactile experience of a cosmetic product.

Scrubs and Exfoliating Agents:

Superior roundness and smoothness of Cospheric microspheres makes them very gentle and effective exfoliating agents to unclog pores and exfoliate dead cells. Round particles has been shown in clinical studies to be less irritating to the skin than irregularly shaped conventional exfoliants with sharp edges, such as apricot kernels and walnut shells.

Take advantage of our coated or colored microspheres to add visual interest, a hint of color, sparkle, or changing color effect without dealing with difficult to disperse pigments.

Anti-Wrinkle Products:

Excellent sphericity and tight particle size of our microspheres will minimize the appearance of fine lines and wrinkles by both filling them and scattering light, creating a soft focus effect. 

Eco-friendly manufacturing:

There are absolutely no solvents or waste in our spherical microparticle manufacturing process. Bulk spheres are supplied to you in dry form. Microparticles that do not meet our tight specifications are recycled back into the process.
