Three washes is usually sufficient to remove the unsulfonated subsidiary. With the stopper removed, gently swirl the ether layer in the sep. funnel twice to separate the remaining aqueous base. Drain this into the 100 mL beaker. Appropriately label a 250 mL beaker. Pour the ether layer into the beaker. Allow the ether to evaporate to near dryness. Cool to room temperature. Add ca 8 mL ethanol (95%). Swirl beaker to mix contents. Quantitatively transfer to a 25 mL graduate using ethanol (95%) rinses. Add ethanol (95%) to bring volume to 15 mL. SPECTROPHOTOMETRIC ANALYSIS Spectrophotometer Parameters: Scan Range: 400-700 nm Scan: 50 nm/in; 5.0 nm/sec. Cell length: 1 cm (Note: Reference and (1) Record the visible spectrum of a blank. Fill the reference cell with distilled water and the sample cell with ethanol (95%). (2) Rinse the sample cell with 2-3 mL of the ether soluble material (in ethanol solution); then fill the cell. Record the visible spectrum of the ether soluble material. (3) Compare the spectra obtained to the spectra attached. The attached spectra represents 150% of the absorbance at each wavelength for similarly analyzed D&C Red No. 6 Lot AA5169. The spectra of the current sample must not exceed the attached spectra at any wavelength in order to pass test. § 80.10 Fees for certification services. (a) Fees for straight colors including lakes.

Whenever in the judgment of the Commissioner the ratio between fees collected (which are based upon experience and the best estimate of costs and the best estimate of earnings) and the costs of providing the service during an elapsed period of time, in the light of all circumstances and contingencies, warrants a refund from the fund collected during such period, he shall make ratable refunds to those persons to whom the services were rendered and charged, except that no refund shall be made where the computed ratable amount for the elapsed period is less than $5.00.

In the case of a foreign manufacturer, the request for certification must be signed by a responsible officer of such firm, and, by his agent who resides in the United States. (e) Show the name and post office address of the actual manufacturer in case such manufacturer is not the person requesting certification of the batch. (f) Be accompanied by the fee prescribed in § 80.10 unless the person has established with the Food and Drug Administration an advanced deposit to be used for prepayment of such fees. In no case shall the Commissioner consider a request for certification of a batch of color additive if the fee accompanying such request is less than that required by § 80.10 or if such fee exceeds the amount held in the advance deposit account of the manufacturer submitting such request for certification. (g) Be accompanied by the sample prescribed in § 80.22 consisting of: (1) Four ounces in the case of straight colors and lakes. (2) Two ounces in the case of repacks and mixtures. A sample accompanying a request for certification must be submitted under separate cover and should be addressed to the Color Certification Branch. (h) The name of a color additive shall be given in the following manner: (1) The name of a straight color shall be the name of the color as listed in Parts 74 and 81 of this chapter.
