Sericin
Sericin is refined form silkworm
body (spun silk gland),pod(pod shell, watt
silk) and silk. SINOSILK is the first
ever to succeed using a unique technology,
extracting and refining sericin in
China.We
are recognizing people's wish for beauty and health by
providing a wide range of products including cosmetics,
textiles and hair care products.
There are 18 kinds of amino acids in
sericin, among which, serine and aspartate have the highest content. Besides, it has the other amino acids necessary to human body, it is an excellent protein. Because in
sericin, about 80% amino cid has hydrophilic lateral group, about 1/3 of which is serine which water absorption is 50 times high than that of glycerin.
Sericin, as the raw material of cosmetic, has excellent moisture absorption and preservative ability. Sericin protein can form a film on the surface of skin and hair so that the water in skin can be preserved, and then the harm to skin cutin can be avoided. By applying it, the skin can be soft and smooth, and the hair can be soft and flexible, and it also benefits for the shaping of hair.
Meanwhite, it will not adhere to hair.
Sericin
is excellent in moisture preservation as it contains serine, one
of the most important amino acids among the NMF. It is also effective in controlling the occurrence of active oxygen,
the factor which breaks down the protection of the skin's surface,
as well as tyrosinase, which causes the skin to freckle. As it is
gentle on the skin and is an excellent moisturizer, protector and
whitening, it is attracting attention as a skin care ingredient.
1.
Excellent
in absorbing and release moisture
Sericin
is smooth and gentle on the skin. Fraichir gives wearers a
silk-like fresh comfortable feeling by reducing the
uncomfortableness of being sweaty and wet.
2.
Moisture
to skin
Sericin
has an amino acid structure similar to NMF (natural moisturizing
factor) which is naturally part of our human makeup. Among these is
"serine," an important moisturizing acid which has a high
consistency in sericin, providing a moistening element. Furthermore,
further purified pure sericin acquires the same amount
of moisture and smoothness found in silk.
3.
Gentle
on the skin
It is as
smooth as silk and does not stick to skin. Yet even after repeated
washing, its effect remains almost the same. It gives a gentle, soft
silky touch.
4.
Skin
Care Functional Material
A
skin care material produced from pure sericin, less
irritant and gentle on delicate skin.
5.
Less
irritant
Silk, a
material soft and gentle on skin, covered with protein. This protein
is further purified and used to coat every yarn. A veil of pure
sericin
softens any irritant touch and protects delicate skin. Even after
repeated washing, its effect remains almost the same. It has been
verified as safe by a medical specialist.
