胆固醇酯被广泛地用于胆固醇性液晶(CLC).
背景
The term "liquid crystals" is used to describe
materials that exhibit the properties of both (crystalline)
solids and (isotropic) liquids. Although there are many
different types of liquid crystals. Choe Guangzhou is a leader
in commercial manufacturing of Cholesterol Esters for the
formulation of Cholesteric Liquid Crystal (CLC) mixtures. These
thermotropic liquid crystal mixtures exhibit unique features
that have generated significant interest in their usage in
personal care products, Liquid Crystal Display, Dyes and Effect
Colors and temperature measurement.
特性
视觉特性
Cholesteric Liquid Crystal mixtures are viscous hydrophobic
liquids. The most obvious and striking feature of the
Cholesteric Liquid Crystal mixtures is their opalescent and
iridescent appearance that is attributed to their ability to
selectively reflect visible light. The wavelengths or colors of
the reflected light are determined by the spacing between the
layers of molecules within the liquid crystalline structure.
Downstream manufacturer can control this molecular spacing to
offer an array of liquid crystal mixtures reflecting different
wavelengths of light, such as red, green, and blue as well as
numerous customized combinations to meet the specific needs of
the cosmetic, dyes, effect color formulators and temperature
measurement (by changing colors).
功能作用
Due to the substantive and occlusive properties of the
cholesterol liquid crystal ester mixtures, these CLC mixtures
are also used in cosmetic and personal care products as vehicles
to aid in the penetration and stabilization of active
ingredients.
