The food additive, quaternary ammonium chloride combination, may be safely used in food in accordance with the following conditions:
（a） The additive contains the following compounds: n- dodecyl dimethyl benzyl ammonium chloride （CAS Reg. No. 139–07–1）; n- dodecyl dimethyl ethylbenzyl ammonium chloride （CAS Reg. No. 27479–28–3）; n- hexadecyl dimethyl benzyl ammonium chloride （CAS Reg. No. 122–18–9）; n- octadecyl dimethyl benzyl ammonium chloride （CAS Reg. No. 122–19–0）; n- tetradecyl dimethyl benzyl ammonium chloride （CAS Reg. No. 139–08–2）; n- tetradecyl dimethyl ethylbenzyl ammonium chloride （CAS Reg. No. 27479–29–4）.
（b） The additive meets the following specifications: pH （5 percent active solution） 7.0–8.0; total amines, maximum 1 percent as combined free amines and amine hydrochlorides.
（c） The additive is used as an antimicrobial agent, as defined in §170.3（o）（2） of this chapter, in raw sugar cane juice. It is added prior to clarification when further processing of the sugar cane juice must be delayed.
（d） The additive is applied to the sugar juice in the following quantities, based on the weight of the raw cane:
| Component | Parts per million |
| n- Dodecyl dimethyl benzyl ammonium chloride | 0.25–1.0 |
| n- Dodecyl dimethyl ethylbenzyl ammonium chloride | 3.4–13.5 |
| n- Hexadecyl dimethyl benzyl ammonium chloride | 1.5–6.0 |
| n- Octadecyl dimethyl benzyl ammonium chloride | 0.25–1.0 |
| n- Tetradecyl dimethyl benzyl ammonium chloride | 3.0–12.0 |
| n- Tetradecyl dimethyl ethylbenzyl ammonium chloride | 1.6–6.5 |
