SEBACIC ACID LAB GRADE 70

Sebacic acid is a naturally occurring dicarboxylic acid with the structure (HOOC)(CH2)8(COOH).

In its pure state it is a white flake or powdered crystal. The product is described as non-hazardous, though in its powdered form it can be prone to flash ignition (a typical risk in handling fine organic powders).

Sebaceus is Latin for tallow candle, sebum is Latin for tallow, and refers to its use in the manufacture of candles. Sebacic acid is a derivative of castor oil, with the vast majority of world production occurring in China which annually exports over 100,000 metric tonnes, representing over 90% of global trade of the product.[citation needed]

In the industrial setting, sebacic acid and its homologues such as azelaic acid can be used as a monomer for nylon 610, plasticizers, lubricants, hydraulic fluids, cosmetics, candles, etc. Sebacic acid is also used as an intermediate for aromatics, antiseptics, and painting materials.

HYDROQUINONE LAB GRADE 70

Hydroquinone, also benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C6H4(OH)2. It has two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also referred to as hydroquinones. The name "hydroquinone" was coined by Friedrich Wöhler in 1843

erythritol FOOD GRADE 99.9

Molecular-Formula: C4H10O4
Molecular Weight: 122.12
CAS No.: [149-32-6]

What is Erythritol?

Erythritol, a polyol (sugar alcohol) is a good-tasting bulk sweetener which is suitable for a variety of reduced- calorie and sugar-free foods. It has been part of the human diet for thousands of years due to its presence in fruits and other foods. Erythritol has a high digestive tolerance, is safe for people with diabetes, and does not promote tooth decay. 

 

Benefits of Erythritol:
Low in calories: Erythritol has a very low caloric content; its value is 0.2 calories per gram for food labeling purposes in the United States and 0 (zero) calories per gram for food labeling purposes in Japan. This very low calorie value is due to erythritol’s unique absorption and elimination process which does not require the metabolism of erythritol. Thus, erythritol is uniquely qualified as a very low calorie bulk sweetener for formulating “light” and “reduced calorie” products which require a 25% or more calorie reduction from the standard formulation.
High digestive tolerance: Erythritol is rapidly absorbed in the small intestine due to its small molecular size and structure. Several clinical studies conducted in Europe and Japan have shown that more than 90% of ingested erythritol is absorbed and excreted unchanged in urine within a 24-hour period. This digestive pathway allows less than 5% of ingested erythritol to reach the large intestine and be fermented into volatile fatty acids or metabolized into carbon dioxide. As a result, foods containing substantial amounts of erythritol are very unlikely to cause gaseous and laxation side effects. A recent clinical study concluded daily consumption of 1 gram per kilogram body weight is well tolerated by adults as compared to sucrose containing foods. 
Safe for people with diabetes: Single dose and 14-day clinical studies demonstrate erythritol does not affect blood serum glucose or insulin levels. Clinical studies conducted in people with diabetes conclude that erythritol may be safely used to replace sucrose in foods formulated specifically for people with diabetes. Of course, those with diabetes should consider the impact on their diet of other ingredients used in foods sweetened with erythritol.
Does not cause tooth decay: Erythritol like other polyols is resistant to metabolism by oral bacteria which break down sugars and starches to produce acids which may lead to tooth enamel loss and cavities formation. They are, therefore, non-cariogenic. The usefulness of polyols, including erythritol, as alternatives to sugars and as part of a comprehensive program including proper dental hygiene has been recognized by the American Dental Association. The FDA has approved the use of a "does not promote tooth decay" health claim in labeling for sugar-free foods that contain erythritol or other polyols.

ETHYL ACETATE LAB GRADE 88

Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc or EA) is the organic compound with the formula CH3–COO–CH2–CH3, simplified to C4H8O2. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, decaffeinating tea and coffee, and cigarettes (see list of additives in cigarettes). Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan, North America, and Europe was about 400,000 tonnes.[3] In 2004, an estimated 1.3 million tonnes were produced worldwide.[4]
