TL;DR: Patch tests with analytical grade triphaenyl phosphate showed positive reactions to 0.05% tripheny1 phosphate and 0.5% tri‐m cresyl phosphate, but on reaction to tri‐p‐cresyl phosphates.
Abstract: A case of triphenyl phosphate allergy from spectacle frames is reported. Patch tests with analytical grade triphenyl phosphate, tri-m-cresyl phosphate, and tri-p-cresyl phosphate in the concentrations 5%, 0.5% and 0.05% pet. showed positive reactions to 0.05% triphenyl phosphate and 0.5% tri-m-cresyl phosphate, but no reaction to tri-p-cresyl phosphate. Gas chromatography of the tricresyl phosphate 5% pet. patch test material supplied from Trolab showed that it contained a mixture of a wide range of triaryl phosphates, including 0.08% triphenyl phosphate which is above the threshold for detecting triphenyl phosphate allergy in our patient.

TL;DR: In this paper, the authors proposed to obtain the titled foam having improved economic efficiency and variability with time, by blending expanding and polymerizing an organic polyisocyanate and a specific amount of a polyfunctional polyester ether polyol, etc., in the presence of a blowing agent, a specific flame-retardant and a foam stabilizer.
Abstract: PURPOSE:To obtain the titled foam having improved economic efficiency and variability with time, by blending expanding and polymerizing an organic polyisocyanate and a specific amount of a polyfunctional polyester ether polyol, etc., in the presence of a blowing agent, a specific flame-retardant and a foam stabilizer. CONSTITUTION:(A) An organic polyisocyanate and a poloyol component consisting of 60-10pts.wt. polyfunctional polyester ether polyol 40-90 substantially trifunctional polyoxypropylene polyol having 2,000-5,000mol.wt. are expanded and polymerized in the presence of (B) a blowing agent (e.g., silicone surface active agent, etc.), (C) 3-30pts.wt. aromatic phosphoric ester compound (e.g., triphenyl phosphate, etc.), (D) 2-10pts.wt. prepolymer obtained by reacting a Br-containing compound having an active carbon (e.g., dibromoneopentyl glycol, etc.) with polyisocyanate, and (E) 0.5-5pts.wt. foam stabilizer (e.g., silicone surface active agent, etc.), to give the aimed polyurethane. EFFECT:Neither change in color nor deterioration of cloth and foam.

TL;DR: In this article, a flame retardant for laminates, formed by adding an additive type flame retardants to a halogenated epoxy compound having at least one epoxy group in the molecule or a reaction product thereof with a Halogenated bisphenol A and adjusting the pH of the obtained composition to a value in the range of 5-7.
Abstract: PURPOSE:To form a flame retardant which can form a resin composition having a long pot life when mixed with a resin for laminates, has good compatibility with a resin and can give flame retardancy to the obtained laminate without detriment to its properties, by adding an additive type flame retardant to a halogenated epoxy resin and adjusting the pH of the obtained composition to a specified value. CONSTITUTION:A flame retardant for laminates, formed by adding an additive type flame retardant to a halogenated epoxy compound having at least one epoxy group in the molecule or a reaction product thereof with a halogenated bisphenol A and adjusting the pH of the obtained composition to a value in the range of 5-7. In adjusting the pH, an organic acid such as p-toluenesulfonic acid, benzoic acid or maleic acid is used. Examples of the additive-type flame retardants include triphenyl phosphate, its derivatives and halogenated diphenyl ethers.
