Sec.  70.20  Packaging requirements for straight colors (other than hair 


dyes).

    Straight colors shall be packaged in containers which prevent 
changes in composition. Packages shall be sealed so that they cannot be 
opened without breaking the seal. An unavoidable change in moisture 
content caused by the ordinary and customary exposure that occurs in 
good storage, packing, and distribution practice is not considered a 
change in composition. If the packaging material is a food additive it 
shall be authorized by an appropriate regulation in parts 170 through 
189 of this chapter.
