EMULSION STABILIZER – BINDER - RHEOLOGY MODIFIER

Introduction :-

Solcolloid is a High performance Derivatised Biopolymer used for stabilization & Rhelogy modification of all kinds of cosmetic preparations based on aqueous & emulsion systems.

The Major concern for any cream & lotion formulations is the Stability & Prevention of Phase Separation at prolonged storage & temperature change Conditions.

Solcolloid provides complete solution for Phase stabilization & binding properties.

The Primary function of any Emulsion Stabilizer should be to bind the droplets of Water & Oil in the emulsion. Along with that, it should also provide colloidal Suspension to the solids & active ingredients in dispersion phase.

Solcolloid is highly stable & effective emulsion stabilizer for aqueous systems & o/w - w/o emulsions. It forms a homogenous gel in water & readily creates a broad & strong matrix within the system suspending & binding the emulsion at micro-level.

Unlike any other Thickening agents based on acrylate copolymers, Solcolloid exhibits excellent salt-tolerance. The concern for Creams & lotions also lies under development of salines at prolonged storage due to slow reaction amongst the active ingredients. The Presence of a strong binder is very essential in formulations based on active ingredients such as Hydroquinone, Kojic Acid etc.

Solcolloid are available in 4 grades differentiated by their viscosities. The simple reason being, the need of the formulation. For those formulations, if the desired viscosity of the finished formulation (cream / lotion) is already achieved, then LV (Low Viscosity) grade is used to provide stabilization & binding. In such formulations where viscosities are to be achieved along with stabilsation properties, CBG-20 & EGM grades are used.

Advantages : -

• The Prepared Solcolloid Gel exhibits high stability characteristics at prolonged storage conditions & in accelerated stability tests.
  
  
• Its very stable even at variant temperature changes.
  
  
• Its compatible to wide range of pH from 3 to 11
  
  
• Highly compatible with all salines & metal salts.
  
  
• Provides very good shelf-life stability to creams & lotions.
  
  
• Provides very good feel to the skin post application of the cosmetic preparation.

• Forms clear solution in water
• Smooth consistency of the resultant product.
• Rapid & Complete dissolution of the product in aqueous phase. However, dissolution is faster in hot water as compared to cold.
• Imparts gloss and soft texture to the resultant product.
• No precipitation of the product even on prolonged storage of the finished product.
• Highly Stable to different climatic conditions.
• Excellent stability to various electrolytes like Sodium Chloride, Sodium Fluoride and to Filler and extender like CaCo3/Dcp etc.
• Does not have fluorescence.
• LD 50 value - The mortality of mice at 800 mg/Kg. was Nil.
