Silway 5401
 
Silway 5401 Fluid is a 13% solution of an ultra-high viscosity dimethiconol fluid ina blend of cyclotetrasiloxane and cyclopentasiloxane. These cyclomethicones have beenspecially blended to prevent freezing and the dimethiconol level selected to maintain a pourable product.

Features:
  • High percentage of dimethiconol ensures excellent substantivity of active ingredients by physical interaction
  • Imparts soft velvety skin feel
  • Conditions hair, especially split ends
  • Detackifies greasy formulations
 
Apply for:
 
  • Substantive character and unique feel make Silway 5401 Fluid well suited for skin creams and lotions, cosmetics, sun screen and tanning products. It can be readily emulsified or combined with volatile silicone, mineral oil and cosmetic esters to provide a delivery vehicle for active ingredients such as sun screens.
  • Provides a soft silky feel and conditioning from hair care products. It is particularly useful against split ends.
 

How to Use：

Silway 5401 Fluid improves the substantivity of other actives, under both water soaking and soap washing regimes. It is therefore possible to incorporate Silway 5401 Fluid into skin care products to provide a water repellent, durable film. These actives may include sun screens, emollients and moisturizers.


Silway 5401 Fluid can also be used to prepare water resistant or waterproof sunscreen lotions with exceptional spreading characteristics.

Formulation Tips:

Emulsion Products:
1. Silway 5401 Fluid can be incorporated directly into the oil phase of the formulation.
2. If temperatures above 60°C (140°F) are being used to melt the oil phase, Silway 5401 Fluid should be added slowly after the formation of the emulsion, and below 50°C (122°F), using a high shear mixer.
Non-Emulsion Products:
It is advisable to add the cosmetic ingredients to the silicone and not vice versa as often ultra-high molecular weight dimethiconol is insoluble with the cosmetic ingredients.
