RECOMMENDATIONS BY COLOR INDUSTRIES. 49 



thout sediment or mud which gives the butter a uniform tint without specks (pp. 



5, 177). 



. AYe recommend that the use of harmless coal-tar colors, such as 



rysoidine, tropseoline, azoflavine, rocelline, ponceau, Bordeaux, Biebrich red, 

 ilphonated fuchsin and naphthol yellow S be allowed, subject to declaration on the 

 ibel of the quality and quantity of the color used (p. 226). 



RELATION OF LABEL TO COLORED FOOD PRODUCTS. 



if it seems wise in the opinion of the commission to allow certain color- 

 Ing matters in food products, then the names of the coloring matter ought to be stated 

 311 the article (p. 109). 



9. * * I suggest that the use of aniline colors should be made proper if it is 

 stated on the label (p. 127). 



10. We recommend * * * that the use of harmless coal-tar colors * * * be 

 lowed subject to declaration on the label of the quality and quantity of the color 



jd (p. 226). 



j| LABELING OF FOOD COLORS AS DISTINGUISHED FROM COLORS FOR OTHER USES. 



11. We recommend that if by any means the Government has the power under 

 le food laws to compel color manufacturers so to do, they be compelled to label all 



:kages containing colors intended to be used in articles of food as colors intended 

 for such purposes as distinguished from colors intended for other purposes; 

 >. 555, 555a). 



THE TEST OF A HARMLESS COLOR. 



12. A harmless color is one "which will neither retard digestion nor have special 

 )hysiological effects when consumed in quantities corresponding to two grains per 



iy per adult" (p. 106). 



QUANTITY OF COLOR TO BE CONSIDERED IN DETERMINING HARMLE8SNESS. 



13. The quantity of 2 grains is mentioned here because in confectionery where 

 ese harmless colors are more used perhaps than in any other product, it would be 

 proportion of one part of color to 3,500 parts, representing 1 pound of color to 3,500 



; |pounds of confectionery, and that is why that was accepted, because that is practi- 

 cally the maximum quantity used in confectionery (p. 106). 



14. In the very minute quantities in which the colors are used in carbonated bev- 

 erages, it would seem a great hardship to prevent us from using coal-tar colors. One 

 ounce of coal-tar red will color satisfactorily from 1,000 to 2,000 gallons of soda water. 



| Of yellow and orange 1 ounce will color from 1,000 to 8,000 gallons. It is readily 

 seen that unless the coloring used is absolutely a violent poison it can have abso- 

 lutely no effect on the consumer who takes it in an 8-ounce glass, and who could 

 not possibly consume half a gallon or a gallon of that product (p. 119). 



15. On this basis 1,000 pounds of butter would contain 420 grains of aniline color 

 (p. 183). 



16. One ounce of color to 30 pounds colored food (p. 135). 



THE NUMBER OF DIFFERENT COAL-TAR COLORS REQUIRED. 



17. And if I were on this committee I would advocate taking out two or three 

 dyestuffs which beyond any shadow of doubt are harmless, and which have been 

 experimented upon, and which would be sufficient for all the purposes of the industry 



* * none of these colors are patented, anybody can manufacture them (pp. 

 147, 148).
