1. A liquid crystal composition comprising:
one silicone surfactant,
a monophenyl silicone oil, and
water so that the liquid crystal composition consists of a liquid crystal structure,
wherein the one silicone surfactant has a HLB value between 4.0 to 10.0 and a viscosity between 400 mm2/s and 850 mm2/s, and
a concentration of the one silicone surfactant in the liquid crystal composition is in the range of 50 to 95% by weight.
