TECHNICAL INFORMATION

​

STABILITY TO CHLORINE:

UMATON 4BB has Good Fastness to Chlorine Bleaching When Already Present on the

Fibre.

 

A Small Reduction in Brightness Occurs When Bleaching is Carried out in a Sollution

Of  Sodium Hypochlorite (Containing About 500 ppm of Available Chlorine). But a

Noticeable Reduction in Brightness is Observed in Solutions With Higher Concentrations

Of Available Chlorine but no Degradation products are Formed. UMATON 4BB is not

Recommended for use Where free Chlorine is Present in the Solution. This is a Standard

Recommendation for all Stilbenetriazine  based Whiteners.

 

APPLICATION:

 

UMATON 4BB is a Fluorescent Whitener Which Gives an Excellent Whitening Effect

On Cellulosic Fibre  at Cold to hot Water Washing Conditions Between 20 Degree C

And Above.

 

INCORPORATION INTO DETERGENTS:
 

UMATON 4BB is Suitable for Addition to Detergent Produced by all Normal Manufacturing

Methods (Spray Drying, Spray Blending, Dry Mixing, etc).The Method of Incorporation does

Not Affect Performance, However the Recommended Method is Either.

 

RECOMMENDATIONS: UMATON 4BB is recommended at Concentrations Between

0.2% to 0.4% The Actual Level Chosen Depends on the Particular Requirements of the user and the Local Washing Conditions.

 

Dilute Solutions must not be Exposed to Natural Light.
