Sodium hyaluronate occurs as white to off- white powder or granules. It is very hygroscopic. Uses: sodium hyaluronate is used as a humectant to increase moisture in the skin, it may also serve as an emulsifier. Sodium hyaluronate is capable of binding 1,800 times its own weight in water. It is the sodium salt of hyaluronic acid and is the most commonly used form. Uses: Sodium Hyaluronic is is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. Uses: antifungal agent Uses: prevents thromboembolic complications Uses: aldosterone antagonist used as an adjunct in the management of chronic heart failure Uses: suitable as substrate for hyaluronidase

Benzocaine Basic info: CAS: 94-09-7 EINECS number: 202-303-5 MF: C9H11NO2 MW: 166.1965 Melting point: 89°C to 90.5°C Boiling point: 310.7 ° C at 760 mmHg Flash Point: 164.2 ° C Vapor Pressure: 0.000589mmHg at 25 ° C Density: 1.17 Mp: 89-92 ° C Ultraviolet absorption used in cosmetics, topical anesthetics, for the wound, ulcer pain and hemorrhoids. Benzocaine Applications: Benzocaine is a local anesthetic commonly used as a topical pain reliever or in cough drops. It is the active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is also combined with antipyrine to form A/B otic drops to relieve ear pain and remove earwax. Benzocaine is used as a key ingredient in numerous pharmaceuticals: Over the counter throat lozenges such as Cepacol. Some glycerol-based ear medications for use in removing excess wax as well as relieving ear conditions such as otitis media and swimmers ear. Some previous diet products such as Ayds. Some condoms designed to prevent premature ejaculation. Benzocaine largely inhibits sensitivity on the penis, and can allow for an erection to be maintained longer (in a continuous act) by delaying ejaculation. Conversely, an erection will also fade faster if stimulus is interrupted. Benzocaine mucoadhesive patches have been used in reducing orthodontic pain. In Poland it is included, together with menthol and zinc oxide, in the liquid powder (not to be confused with the liquid face powder) used mainly after mosquito stings. Today's ready made Pudroderm was once used there as pharmaceutical compound.
