Exposure Standards and Regulations
Drug products containing active ingredients offered over-the-counter (OTC) for the treatment of boils. (a) ... /Cholesterol has/ been present in OTC boil treatment drug products. There is a lack of adequate data to establish general recognition of the safety and effectiveness of these or any other ingredient for OTC use for the treatment of boils. ... Based on evidence currently available, any OTC drug product offered for the treatment of boils cannot be considered generally recognized as safe and effective. (b) Any OTC drug product that is labeled, represented, or promoted for the treatment of boils is regarded as a new drug within the meaning of section 201(p) of the Federal Food, Drug, and Cosmetic Act (the act), for which an approved application or abbreviated application under section 505 of the act and part 314 of this chapter is required for marketing. In the absence of an approved new drug application or abbreviated new drug application, such product is also misbranded under section 502 of the act. (c) Clinical investigations designed to obtain evidence that any OTC boil treatment drug product is safe and effective for the purpose intended must comply with the requirements and procedures governing the use of investigational new drugs set forth in part 312 of this chapter. (d) After May 7, 1991, any such OTC drug product that contains ... cholesterol ... initially introduced or initially delivered for introduction into interstate commerce that is not in compliance with this section is subject to regulatory action.

  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: A Theoretical Oxygen Demand of 27% was observed for cholesterol in seawater using an enriched inoculum of hydrocarbon oxidizing bacteria(1).

12.3 Bioaccumulative potential

An estimated BCF of 270 was calculated for cholesterol(SRC), using an estimated log Kow of 8.7(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
