A and Vitamin E Drops

Mix the vitamins with Cremophor RH 40 (and DL-alpha-tocopherol, if used) at 60°C. 

Add solution of preservatives (at 37°C) slowly, with stirring. Clear, yellow, viscous liquids are formed. 

Heat mixture items 1 to 3 to about 65°C, stir well. 

Slowly add the mixture of items 4 and 5. Color is yellow, and clarity should be clear (turbity units 25 FTU). It must be tested to see whether the ethanol concentration has a sufficient preservative efficiency. The addition of butylhy-droxytoluene as antioxidant is recommended.
