Sericin

Sericin

 

(also silk gum), a viscous protein of natural silk constituting approximately one-third of the silk’s weight. It is characterized by a high content of the amino acid serine (up to 40 percent). Sericin cements the filaments of fibroin, the other protein of silk. In contrast to fibroin, sericin is soluble in hot water and alkaline solutions.

Key ingredients include Amisil, a silicone and amino based ingredient that reduces volume, improves softness and aids thermal protection; Polisil, an active conditioning ingredient that easily adheres to damaged hair strands and helps define clusters, hydration and reduces frizz; creatine, a microparticle penetrates deep into the fibers, recovering hair damaged by chemical and physical processes, increasing hair fiber resistance; sericin, an amino acid to rebuild chemically-processed hair for long-lasting softness; keratin; panthenol; and cotton and linen oil, which improves workability and manageability.
The result is a delicate double fibroin filament, which is coated by a gum called sericin.
