PRODUCT FAMILY
Speciality Cosmetic Silicone Elastomers
Silicone elastomer gels deliver silky texture, soft-focus blurring, oil control, and active delivery in a single ingredient. NISHKA's elastomer family — NISH 4011, NISH EL 450, and NISH EL455 — is built on high molecular weight Dimethicone/Vinyl Dimethicone Crosspolymer chemistries, dispersed in either Cyclopentasiloxane carrier (for volatile-carrier formulations) or non-cyclic Dimethicone and natural oil carriers (for D5-restricted markets). These elastomer gels are formulated into premium primers, foundations, BB and CC creams, sun protection lotions, and skincare textures across global cosmetic markets.
Family at a Glance
The Chemistry
Silicone elastomers are three-dimensional crosslinked polymers — unlike the linear chains of dimethicone fluids, elastomers form a network structure that gives them their distinctive gel texture and optical properties. The crosslink density controls the modulus: higher crosslink density gives a firmer gel with stronger oil absorption and mattifying effect; lower density gives a softer gel with greater cushion and skin adhesion. Dispersed (Propyl Trisiloxane, D5, Dimethicone), elastomers can be incorporated directly into formulations without dilution or pre-processing. The carrier choice matters: D5-based elastomers deliver faster initial feel; dimethicone-based elastomers leave a more substantive conditioning finish.

Common Questions
Silicone Elastomers — Frequently Asked
-
Silicone elastomer gels deliver silky texture, soft-focus blurring, oil control, and active delivery in a single ingredient. NISHKA's elastomers — NISH 4011, NISH EL 450, and NISH EL455 — are built on Dimethicone/Vinyl Dimethicone Crosspolymer chemistry and are formulated into primers, foundations, BB and CC creams, sun protection lotions, and skincare textures.
-
Cyclopentasiloxane (D5)-based elastomers such as NISH EL 450 deliver a faster initial feel, while Dimethicone-based elastomers such as NISH EL455 leave a more substantive conditioning finish and suit D5-restricted markets. Both provide the same crosspolymer benefits — blurring, oil control, and smooth glide — and are interchangeable in most formulation systems.
-
NISHKA elastomers are supplied as gels already dispersed in a carrier fluid (Cyclopentasiloxane, or Dimethicone and natural oils), so they can be incorporated directly into formulations without dilution or pre-processing.
-
Crosslink density controls the gel's modulus. Higher crosslink density gives a firmer gel with stronger oil absorption and a mattifying effect; lower density gives a softer gel with greater cushion and skin adhesion.
