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. Read more about Use of Opaque Microspheres in Cosmetics, Personal Care and Skin Care Industry.
Color Matching Capability:
Creams, Lotions and Cleansers:
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.
