Introduction: Hexamethyldisiloxane (silicone ether, MM sealing agent) is a colorless and transparent liquid that is prone to deliquescence. Insoluble in water, soluble in various organic solvents. Used as silicone oil, silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, etc. Obtained by hydrolysis of trimethylchlorosilane. The physical properties of hexamethyldisiloxane colorless and transparent liquids. Easily deliquescent, flammable, and in contact with high heat, open flames, and strong oxidizing agents, there is a risk of combustion. Boiling point 99.5 ℃. Flash point -1.1 ℃. Relative density (d2525) 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in various organic solvents. Hexamethyldisiloxane is an important primary organic silicon raw material, often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas c...

Name: Menthol
CAS No.: 15356-70-4;98167-53-4;89-78-1;1490-04-6
Appearance: Colourless, transparent hexagonal or needlelike crystals.
Solubility: This product is highly soluble in ethanol, chloroform, or ether, and only slightly soluble in water.
Specific rotation:- 49°~-50°
Melting point: 42~44℃
Boiling point: 212 ℃
Flash point: 93 ℃
Refractive index: 1.4615
Solubility: insoluble in ethanol, 95% ethanol, ether, and water; Slightly soluble in hot benzene and 95% ethanol.
Application category:
Menthol is widely used in inhalants, oral suspensions, oral syrups, topical preparations, and tablets.
Characteristics:
This product is a colorless needle shaped or prismatic crystalline or white crystalline powder; It has a special aroma of mint, with a spicy taste at the beginning and a cool aftertaste; Ethanol solution exhibits neutral reaction.
Melting point:
The melting point of this product is 42-44℃ (General Rule 0612).
Specific Rotation:
Take this product, weigh it accurately, dissolve it in ethanol and dilute it quantitatively to make a solution containing about 0.1g per 1ml. Determine according to the method (General Rule 0621), and the specific rotation should be -49 to 50 °.
Menthol is widely used as a flavoring or flavoring agent in pharmaceuticals, candies, and cosmetics. In addition to its unique mint aroma, naturally occurring L-menthol also has a cooling function and is used in many topical preparations. Mannitol has a similar effect to this product due to its endothermic effect during dissolution; Unlike mannitol, L-menthol can directly interact with cooling receptors in the human body. D-menthol does not have a cooling effect. Racemic menthol has approximately half the effect of L-menthol. When used to prepare flavored tablets, menthol is usually dissolved in 95% ethanol and then sprayed onto the tablet particles, rather than being used as a solid excipient. Menthol has been studied and considered as a transdermal enhancer. It can also be used in perfume and tobacco products, and as a therapeutic agent.
