Application characteristics:
(1)The
silk powder is an excellent natural moisturizing factor because
of the presence of hydrophilic gene in the structure of silk. It
can attach a very thin silk powder layer to the surface of skin,
which can absorb or release water with the change of the
temperature and humidity of skin. This has certain preventive and
therapeutic effects on skin protection, preventing and curing
various skin diseases caused by moisture and drying.
(2)The
crystalline structure of silk powder can reflect part of
ultraviolet ray, and the hollows formed by the spiral structure
can again absorb part of ultraviolet ray, so it will make the
better sun-screening effect by using the compound of silk powder
and sun-screening agent in sunscreen products.
(3) Silk
powder has a unique ability of keeping the oil, which makes it
more suitable to be used in cosmetics for oily skin.
(4)The
structural features of silk powder can help reduce the reflected
light. When being used in cosmetics in which the mica powder is
taken as substrate, it can reduce the reflected light and make
the skin show vivid and soft colors naturally. Compared with
talcum powder and titanium dioxide, silk powder has excellent air
permeability, users would feel particularly smooth after applying
cosmetics containing silk powder.
