"Silasoma"
is water dispersion of microcapsule containing UV filter. The
microcapsule is new material of silicone system, silicone resin
polypeptide, which we completed in 1997. It had been difficult
to produce microcapsules with the material of silicone system
in the past. However, we have succeeded to enable to have microcapsules
by silicone resin polypeptide which is hybrid polymer consists
of hydrolyzed protein and silicone. Since "Silasoma" consists
of a hybrid of Hydrolyzed protein with remarkable affinity for
hair and skin, and silicone with harmlessness, its innovative multi-functionality
generates great possibility of a wide range of application for
DDS(Drug Deliver System).
