Phloroglucinol: Does not have an individual approval but may be used under an appropriate group standard
On the basis of the available data, the CIR Panel cannot conclude that Phloroglucinol is safe for use in cosmetic products until the appropriate safety data have been obtained and evaluated.
Ingredients for which the data are insufficient and their use in cosmetics is not supported
A - Alimentary tract and metabolism
QA - Alimentary tract and metabolism
Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)

説明Phloroglucinol is a naturally occurring phenol that exhibits diverse biological activities. Phloroglucinol protects V79-4 Chinese hamster lung fibroblast cells from oxidative stress and inhibits lipid peroxidation by scavenging reactive oxygen species (ROS). It induces apoptosis in HT-29 human colon cancer cells and inhibits metastasis of BT549 and MDA-MB-231 human breast cancer cells. Phloroglucinol protects primary neurons from β-amyloid-induced dendritic spine loss in vitro and shortens the latency to find the platform in a Morris water maze test in an Alzheimer’s disease (AD) mouse model. Phloroglucinol has been used to stain histological plant sections and in the synthesis of numerous natural products. Phloroglucinol slows the frequency and decreases the amplitude of contraction in isolated rabbit and rat intestine at a concentration of 100 and 1 μM, respectively. Formulations containing phloroglucinol have been used as antispasmodics.
使用Phloroglucinol is mainly used as a coupling agent in printing. It is an active component of Tollen's reagent and Gunzburg reagent used to test pentoses and hydrochloric acid in gastric juice respectively. In analytical chemistry, it is used to study condensed tannins by means of depolymerization. It is also involved in the synthesis of 2,4,6-triamino-1,3,5- trinitrobenzene, trinitrophloroglucinol and pharmaceuticals like flopropione.
一般的な説明Phloroglucinol is a trihydroxybenzene with antithrombotic, profibrinolytic, antimicrobial, antimalarial, cancer chemopreventive, anti-HIV and anti-leishmanial activities. Phloroglucinol (PG) is a biosynthetic precursor of the 2,4-diacetylphloroglucinol (DAPG) an antibiotic against soil-borne diseases. Phloroglucinol is a useful intermediate because it is polyfunctional.
使用用途多官能性であるフロログルシノールは、有機合成の中間体として有用です。主に医薬品や爆薬の合成原料などに使用されます。 例えば、フロプロピオンの合成原料に利用されます。ジアゾ染料と結合して速やかに黒色になるため、印刷のカップリング剤としても使用可能です。リグニンと呈色反応を示し、分析試薬に用いられます。ペントースなどの検出や定量 (トレンス反応) にも有用で、フロログルシノール反応と呼ばれています。
純化方法Crystallise the triol from water, and store it in the dark under nitrogen. [Beilstein 6 IV 7361.]
