Pharmaceutical raw materials used in synthesizing new medications



Equilin is an estrogen from horses. It is one of the estrogens present in the mixture of estrogens isolated from horse urine and marketed as Premarin. Premarin became the most commonly used form of estrogen for hormone replacement therapy in the United States of America. Estrone is the major estrogen in Premarin and equilin is present as about 25% of the total. Estrone is a major estrogen that is normally found in women. Equilin is not normally present in women, so there has been interest in the effects of equilin on the human body.

Ethyl Cellulose

Ethyl cellulose is also called ethocel, EC for short. Structural Formula: [C6H7O2 (OC2H5)3] n CAS No. : 9004-57-3 1. Ethyl Cellulose(EC) Appearance Ethyl Cellulose(EC) is white or light grey free-flowing powder, odorless. 2. Ethyl Cellulose(EC) Properties Commercial Ethyl Cellulose(EC) is usually insoluble in water but soluble in various kinds of organic solvents. It has good thermal stability and low ash content when burning. In addition, it seldom gets sticky or bitter, so can form tough and tensile films and maintain flexibility even at low temperatures. The product is non-toxic, strong in antibiotic effects and metabolically inert but apt to oxidative degradation in the sun or UV light (ultraviolet light). The special-purpose Ethyl Cellulose(EC) can also be classified into types soluble in alkaline liquor or pure water. 3. Ethyl Cellulose(EC) Application With adhesion, filling and film-forming functions, the product can be used in resin synthetic plastics, coating, rubber substitutes, printing ink and insulation materials, or as adhesive agent and textile finishing agent. In addition, it can act as animal feed additive in agriculture and animal husbandry, or adhesives in electronic products and propellant of military industry. According to the uses, the commercial Ethyl Cellulose(EC) can be divided into two categories of products: the industrial grade and the pharmaceutical grade, and usually soluble in organic solvents. For the pharmaceutical grade Ethyl Cellulose(EC), the quality standard should meet Chinese Pharmacopoeia 2010 Standard (or USP XXIV/NF19 Standard or JP Standard). Because of water insolubility, Ethyl Cellulose(EC) can mainly act as tablet binders, thin film coating materials, and retardants of framework materials or be used for the preparation of different types of sustained-release tablets. Ethyl Cellulose(EC) can be used as the mixed material for coating sustained-release preparations pellets, the organic carrier for the preparation of electronic pastes or as the encapsulation excipient for the preparation of sustained-release microcapsules to maintain sustained release of efficacy and avoid premature reaction of some water-soluble drugs. It can also be used in various kinds of dosage forms as dispersing, stabilizing and water-retaining agents to prevent drugs from getting wet and bad, and promote the safe storage of drugs.

Ethyl Oleate Description:
Ethyl oleate is used as a solvent for pharmaceutical drug preparations involving lipophilic substances such as steroids. It also finds use as a lubricant and a plasticizer. Ethyl oleate is regulated as a food additive by the Food and Drug Administration under "Food Additives Permitted for Direct Addition to Food for Human Consumption. Ethyl oleate is a fatty acid ester formed by the condensation of oleic acid and ethanol. It is a colorless to light yellow liquid. Ethyl oleate is produced by the body during ethanol intoxication. Ethyl oleate is used as a solvent for pharmaceutical drug preparations involving lipophilic substances such as steroids. It also finds use as a lubricant and a plasticizer. Ethyl oleate is regulated as a food additive by the Food and Drug Administration under "Food Additives Permitted for Direct Addition to Food for Human Consumption", Ethyl oleate has been identified as a primer pheromone in honeybees.
Ethyl oleate is one of the fatty acid ethyl esters (FAEE) that is formed in the body after ingestion of ethanol. There is a growing body of research literature that implicates FAEEs such as ethyl oleate as the toxic mediators of ethanol in the body (pancreas, liver, heart, andbrain) Among the speculations is that ethyl oleate may be thetoxicmediator of alcohol in fetal alcohol syndrome. The oral ingestion of ethyl oleate has been carefully studied and due to rapid degradation in the digestive tract it appears safe for oral ingestion. Ethyl oleate is not currently approved by the U.S. Food and Drug Administration for any injectable use. However, it is used by compounding pharmacies as a vehicle for intramuscular drug delivery, in some cases to prepare the daily doses of progesterone in support of pregnancy. Studies which document the safe use of ethyl oleate in pregnancy for both the mother and the fetus have never been performed.
Ethyl Oleate Application:
Ethyl Oleate BP/EP is a pharma grade material used in many applications such as pharmaceutical preparations, food, cosmetics and health & beauty applications. Ethyl Oleate can function as solvent, glossing agent and emollient. It is an excellent solvent and good moisturiser. Suitable for skin care, hair care and colour cosmetics.
