IN GENERAL, MATERIALS WHICH ARE TOXIC AS STORED OR WHICH CAN DECOMP INTO TOXIC COMPONENTS ...

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

QA - Alimentary tract and metabolism

Chlorobutanol is a detergent preservative with a broad spectrum of antimicrobial activity. _In vitro_, chlorobutanol demonstrated to inhibit platelet aggregation and release via unknown mechanisms. A study proposes that the antiplatelet effect of chlorobutanol may occur from inhibition of the arachidonic acid pathway. It attenuated thromboxane B2 formation, elevation of cytosolic free calcium, and ATP release, and additionally exhibited a significant inhibitory activity toward several aggregation inducers in a time- and concentration-dependent manner. Chlorobutanol may exert a direct negative inotropic effect on myocardial cells to isometric tension produced by the heart. Chlorobutanol was shown to induce conjunctival and corneal cell toxicity _in vitro_: at a concentration of 0.1%, Cbl caused near depletion of the squamous layer while degeneration of corneal epithelial cells, generation of conspicuous membranous blebs, cytoplasmic swelling, and occasional breaks in the external cell membrane were observed at a concentration of 0.5%.

As a detergent, chlorobutanol disrupts the lipid structure of the cell membrane and increases the cell permeability, leading to cell lysis. It induces conjunctival and corneal cell toxicity via causing cell retraction and cessation of normal cytokines, cell movement, and mitotic activity. It disrupts the barrier and transport properties of the corneal epithelium as well as inhibits the utilization of oxygen by the cornea. Chlorobutanol also inhibits oxygen use by the cornea, which increases susceptibility to infection.

Following oral administration in healthy subjects, the plasma concentration fell by 50% in 24 hours post-administration.

Under physiological conditions, chlorobutanol is unstable. The mean urinary recovery accounts for 9.6% of the dose orally administered.

The volume of distribution was approximately 233 ± 141 L in healthy individuals receiving oral chlorobutanol.

In healthy subjects, the clearance was approximately 11.6 ± 1.0 mL/min following oral administration.

Used as a plasticizer for cellulose esters and ethers, in medical practice (preservative, antimicrobial agent, anesthetic in dentistry, sedative and hypnotic, antiemetic), and in veterinary practice (antiseptic, local anesthetic, sedative, antiemetic, antipruritic, and hypnotic); [HSDB]

By action of potassium hydroxide on a solution of chloroform and acetone.

The para and ortho positions of phenols condense at the carbonyl group of acetone to make bisphenols... If the H atom is activated, ClCH- compounds add to the carbonyl group in the presence of stong base; chloroform gives chloretone.

CHLOROBUTANOL HAS BEEN WIDELY EMPLOYED AS VERY EFFECTIVE PRESERVATIVE IN EYEDROPS, USUALLY IN 0.5% CONCN, WITHOUT PRODUCING CLINICALLY RECOGNIZED OCULAR DISTURBANCE, EVEN THOUGH APPLIED SEVERAL TIMES A DAY FOR SEVERAL YR.

Chlorobutanol may be anhyd or it may contain up to about 1/2 mol of water. Label shall indicate whether chlorobutanol is anhyd or hydrate.
