APPLICATION : Requiring water soluble derivative of BENZOPHENONE—4

COSTMETIC Formulations

1) Used to protect both the formulation and substrate.
2) Is substantive to skin and hair.
3) Excellent skin protection against sunburn in aqueous based formulations.
4) Reduce ageing effect of solar rays on skin and help prevent freckling.
5) Used in sun tan lotions, and body creams for this purpose.
6) As a stabilizer for shampoos and other aqueous based firmulations to prevent color fading.
7) Improves light stability of hair colors and in hairspray formulations recommended for tinted or      bleached hair.
8) Used for water based cosmetic colors and perfumes.

TEXTILES :

1. To improve colors fastness of dyed fabrics and to prevent yellowing of wool.
2. Prevents discoloration of synthetic fibers. Can be diffused into the surface from aqueous base.

APPLICATIONS : BENZOPHENONE 12 is a highly effective substituted benzophenone ultraviolet light absorber that is readily soluble in most polymers. B-12 is particularly suited to providing maximum protection to polymers of ethylene, propylene, vinyl chloride, styrene, ethylene vinly acetate and to protective coatings based upon these polymers.

As a result of its unique preferential absorption characteristics in the 2900 to 4000 A. of the U V Spectrum, it imparts a high level of resistance to photodegradation of the polymer.

Generally, the incorporation of 0.1 to1.0% (Based on polymer weight)of B-12 is required.

TOXICITY
For polymers, B-12 is permitted for use as a stabilizer in olefin polymers at levels not exceeding 1.0 percent weight of the polymer.

APPLICATIONS :
1. B-3 is recommended for protecting many plastics, including Polystyrene, Polyvinyl chloride, methacrylate Polymers, and particularly Polysters against U. V. degradation over Prolonged exposure. B-3 because of its law melting point and excellent compatibility with most plastics, can be readily dispersed in systems, which low temperature processing.

2. The dosage level of B-3 varies with the thickness and U.V. light sensitivity of the plastic. Standard use level varies from 0.1 to o.2% for normal applications.

3. B-3 imparts a minimum amount of initial color to the plastic and does not yellow when subjected to B-3 the normal temperature used for cross-linking heat-cured polyesters.

4. Since B-3 absorbs damaging radiation between 2000 and 4000 Angstrom and is soluble in a wide range of solvents, it can be used to protect clear varnishes and lacquers, as well as linseed oil-based alkyds and Phenolic coating intended for use on U. V. sensitive surface. Usually 0.5 % to 1 % B-3 is required.
