Dispersions in the context of cosmetics refer to a mixture where fine ground particles are distributed uniformly throughout a liquid or another solid in which they are not soluble. This process ensures consistent color and texture in the final product. Achieving a successful dispersion requires determining the right combination of components for each formulation, which is essential to attain optimum color strength and stability. Sensient Beauty, known for its expertise in color and formulation technology, utilizes advanced dispersion techniques to enhance the performance, appearance, and longevity of various beauty products, including foundations, lipsticks, and eyeshadows.

油か水か？
There are two broad categories of dispersions from Sensient — Oil dispersions which include Covascreen, Covanol and Covalight; as well as water dispersions which include Covasop, Covarine WS, Covarine WN, Covasorb and Natpure Screen TWG.
Oil dispersions involve dispersing fine particles in an oil medium. They are typically used in oil-based products such as certain types of foundations, lipsticks, and sunscreens. Oil dispersions tend to provide a richer, more emollient texture, which can be particularly beneficial for dry skin. They often offer better stability for oil-soluble pigments and active ingredients. Additionally, oil dispersions can enhance the product’s spreadability and adherence to the skin, providing a smooth, even application with a lasting finish.
Water dispersions involve dispersing fine particles in a water-based medium. These are commonly used in products like water-based foundations, lotions, gels, and personal care products such as toothpaste, liquid soaps, and shampoos. Water dispersions tend to be lighter and more refreshing, making them suitable for oily or acne-prone skin and hair types. They generally dry faster and feel less greasy compared to oil dispersions. Water dispersions are easier to wash off and can be more comfortable in hot and humid climates. They provide a lighter, more breathable finish while maintaining good pigment distribution and color intensity.
Covarine WSとWNディスパージョン：その違いは？
Covarine WS dispersions involve synthetic pigments, known for their superior chemical purity, in a water/glycerin mixture.
