  • Silicone modified polynorbornene is a silicone-based film formers created by introducing silicone groups into polynorbornene, an extremely rigid polymer. Dissolved in volatile oil agents, it exhibits strong film-forming properties and high adhesion. The resulting film combines hardness with flexibility, imparting water resistance, abrasion resistance, and excellent oil repellency to cosmetic films.
  • Silicone modified pullulan is a film former created by introducing silicone groups into the water-soluble polysaccharide pullulan. Dissolved in volatile silicone fluids, it produces films that combine hardness and flexibility, imparting water resistance, abrasion resistance, and excellent oil repellency to cosmetic films.
  • Silicone acrylates are a graft polymer composed of acrylic polymer and dimethylpolysiloxane. They are dissolved in volatile silicone fluids, and the resulting film is flexible with high adhesion, imparting water resistance, sebum resistance, and abrasion resistance to cosmetic films.
  • Trimethylsiloxysilicates are silicone-based film formers. Dissolved in volatile oil agents, they form films exhibiting high water repellency, imparting water resistance and sebum resistance to cosmetic films.
    We offer a diverse product lineup with varying film hardness and solvents.

KP-545

KP-545

A cyclopentasiloxane solution of a graft copolymer consisting of acrylic polymer and dimethylpolysiloxane. Evaporation of volatile components forms a film with excellent water resistance, oil resistance, abrasion resistance, oxygen permeability, and lasting cosmetic effect. The film-forming agent (acrylates/dimethicone) copolymer has the characteristics of both acrylic resin and silicone.

KP-549

KP-549

A volatile dimethicone solution of a graft copolymer consisting of acrylic polymer and dimethylpolysiloxane. Evaporation of the volatile components forms a film with excellent water resistance, oil resistance, abrasion resistance, oxygen permeability, and cosmetic effect retention. The film-forming agent (acrylates/dimethicone) copolymer has the characteristics of both acrylic resin and silicone.

KP-545L

KP-545L

A volatile dimethicone solution of a graft copolymer consisting of acrylic polymer and dimethylpolysiloxane. Evaporation of the volatile components forms a film with excellent water resistance, oil resistance, abrasion resistance, oxygen permeability, and lasting cosmetic effect. The film-forming agent (acrylates/dimethicone) copolymer has the characteristics of both acrylic resin and silicone.

KP-550

KP-550

An isododecane solution of a graft copolymer consisting of acrylic polymer and dimethylpolysiloxane. Evaporation of volatile components forms a film with excellent water resistance, oil resistance, abrasion resistance, oxygen permeability, and lasting cosmetic effect. The film-forming agent (acrylates/dimethicone) copolymer has the characteristics of both acrylic resin and silicone.

KP-543

KP-543

A butyl acetate solution of a graft copolymer consisting of acrylic polymer and dimethylpolysiloxane. Evaporation of volatile components forms a film with excellent water resistance, oil resistance, scrub resistance, oxygen permeability, and lasting cosmetic effect. The film-forming agent (acrylates/dimethicone) copolymer has the characteristics of both acrylic resin and silicone.
