Their products range:
MALIC ACID [ C4H6O5 ]
Malic Acid is an organic compound that is the active ingredient in many sour and tart foods. It can be blended with multiple food acids, sugars, high intensity sweeteners, flavors and seasonings to create distinctive taste experiences in foods, beverages, and confections.
Malic Acid is also used in the manufacture of skin and dental care products and can be used in a number of technical applications, such as Electroplating and metal cleaning.
Malic Acid is generated during metabolism of living cells in the Kreb’s cycle and occurs naturally in all fruits and many vegetables. It is the predominant acid in apples thus the name is derived from the Latin name for apples which is malus. Malic Acid is also essential in the preparation of medical products such as throat lozenges, cough syrups, effervescent powdered preparations, toothpaste, and mouthwash.
Additionally, Malic Acid is used in the manufacture of skin care products to rejuvenate and improve skin conditions and also can be used in a number of technical applications, such as metal cleaning, textile dying to improve color value, and paint, preventing the formation of skin on the top layer during storage.
DETAILED APPLICATIONS
Carbonated Beverages
Adding Malic Acid improves artificially sweetened products. Flavors are enhanced, allowing the use of less additives, and the overall flavor profile is broader, smoother and more natural.
Non-carbonated Beverages
Malic Acid is a preferred acidulant for still beverages (fruit drinks, nectars, iced-teas, sports drinks, calcium fortified juices), because it enhances fruit flavors, improves pH stability, and masks the aftertaste of artificial sweeteners and some salts.
Ciders and Wines
For alcoholic apple ciders, Malic Acid is added to maintain a consistent “sharp” taste.
Confectionaries
Malic Acid gives an appealing tartness to hard, soft, tableted, and sugarless candies as well as chewing gum. Blending multiple acids creates unique tasting confections. Malic Acid’s high solubility allows it to be blended with cooled confections. Adding acids at the end of the candy making process minimizes sugar inversion.
Hard Candy
Malic Acid boosts sourness intensity and enhances fruit flavors. It has a lower melting point than other food acids this means that it can be incorporated into molten hard candy without added water. The shelf life is increased as the initial moisture level in the hard candy is lower.
Soft Candy
In agar, gelatin or pectin-based candies such as jellies and gummies, Malic Acid is used to achieve a natural fruit flavor profile, uniform & controlled gelling, and good product clarity.
Powdered Mixes
In iced tea, sports drink, or fruit soup dry mixes, Malic Acid is preferred due to its rapid dissolution rate and flavor enhancement qualities. Since Malic Acid provides more sourness than Citric Acid, less acidulant is required and unit weight can be reduced.
Calcium Supplements and Calcium-fortified Beverages
In liquid calcium supplements, Malic Acid adds a tart and fruity flavor while controlling the pH and improving the solubility and bio-availability.
Low Calorie Beverages
Malic Acid’s extended sourness masks sweetener aftertaste and its blending and fixative abilities give a balanced taste profile.
Acidified Dairy Products
Whey-based protein beverages acidified with Malic Acid have enhanced fruit flavor with less noticeable whey flavor. Fruit flavored milk drinks made with fruit juice and acidified with Malic Acid have improved flavor and palatability.
Fruit Preparations and Preserves
Malic Acid enhances fruit flavors and creates a more natural flavor profile in jams, jellies, and fruit preparations. Fruit preparations are acidified with Malic Acid so that the fruit flavor stays strong, even when the fruit preparation is used in dairy products, frozen desserts or baked goods.
Desserts
Malic Acid is an economical fruit flavor enhancer in sherbets and water ices. In gelled desserts, Malic Acid enhances fruit flavors and helps stabilize pH to control gel texture.
Bakery Products
Bakery products with fruit fillings (cookies, snack bars, pies, and cakes) have a stronger and more naturally balanced fruit flavor when the fruit filling includes Malic Acid.
Medical and Personal Care Products
In throat lozenges, cough syrups, and effervescent powdered preparations, Malic Acid enhances fruit flavor and can diminish the flavor impact of active components. As Malic Acid stimulates saliva flow, it can be used in tooth-cleaning preparations and mouthwashes. Germicidal compounds are used in combination with Malic Acid in soaps, mouthwashes, and toothpaste.
Acid-Based Facial Products
Malic Acid can be used in skin care products to rejuvenate and improve skin conditions.
Oil Field Applications
Demands for Malic Acid in the oil industry are rapidly increasing. The product is used to aid in the transfer of raw crude from the well to the refinery.
Gypsum Cement Retarders
Malic Acid is used in Gypsum cement to control the rate of setting of the cement by retardation.
Acrylic Fibre Production
Acrylic fibre whiteness is enhanced by the addition of Malic Acid during the manufacturing process and also helps in the control of polymerization reaction and prevents oxidation.
FUMARIC ACID [ C4H4O4 ]
Fumaric Acid is a white crystalline chemical compound widely found in nature. Fumaric Acid is an essential ingredient in plant life. It is used in the manufacture of medicines, drinks, food, animal feed, cleansing agents, unsaturated polyester, alkyd resins, and printing inks. When used as a food additive, Fumaric Acid results in long lasting sourness and flavor impact. Fumaric Acid is generally used in beverages and baking pre-mixes for Tortilla breads and bakery products.
DETAILED APPLICATIONS
Animal Feed
Fumaric Acid has proven to be a particularly effective additive to piglet feed during the post-weaning period. The inclusion of Fumaric Acid and the resultant adjustment of the pH value demonstrate improved weight gain, food consumption, and feed conversion ratio. Fumaric Acid remains longer in the gut and helps to maintain pH throughout killing harmful microorganisms.
Industrial Uses
Industrial uses of Fumaric Acid include: unsaturated polyester, alkyd resins, printing inks, paper sizing, starch and helps in lowering reaction temperatures and modify properties.
Cleaning Agents for Dentures/Bath Salts
Fumaric Acid can be used with other ingredients to make cleaning agents for dentures and bath salts. Low moisture absorption and solubility helps to keep the integrity of formulations.
Tacos
Shelf life of dry tortilla mixes is extended because Fumaric Acid does not absorb moisture during storage and distribution. In wheat flour tortillas, the addition of Fumaric Acid results in easily machined dough and faster production rates.
Breads
Fumaric Acid acts as an instant flavoring agent for rye and sourdough breads. Fumaric Acid is added to dough ingredients during the dry blending step. In English muffins, Fumaric Acid significantly increases porosity. Dough machinability is improved and more sourness is provided per unit weight.
Fruit Juice Drinks
Fumaric Acid provides more sourness per unit weight than other acidulants used in fruit juice drinks. This substantially reduces the acidulant cost. Using Fumaric Acid helps to stabilize the pH of a fruit juice drink, which in turn stabilizes color and flavor.
Wine
Fumaric Acid can economically acidify wine with no detectable difference in flavor. Fumaric Acid also prevents secondary fermentation after bottling and can act as a clarifier when low concentrations of copper and iron are present.
Confectioneries
Fumaric Acid extends the shelf life of acid coated candies because it does not absorb moisture during storage and distribution. Maintaining a low moisture level retards sucrose inversion.
Gelatin Desserts
Fumaric Acid significantly reduces acidulant costs in gelatin desserts. Fumaric Acid maintains non-caking and free-flowing qualities. By keeping the moisture content low, Fumaric Acid helps to maintain the stability of flavor components. Fumaric Acid also increases gel strength, so food processors may reduce normal gelatin content by about 2%.
Pie Fillings
In pie fillings, Fumaric Acid can be mixed directly with the starch and sugar ingredients. Fumaric Acid lowers costs by reducing the quantity of food acid needed in product formulations. Fumaric Acid also improves smoothness and extends the critical cook times for optimum gelation.
Egg White Foams
Fumaric Acid can promote maximum volume in both egg-white foams and end products based on egg-white foams.
Desserts
Fumaric Acid is an economical fruit flavor enhancer in sherbets and water ices. In gelled desserts, Fumaric Acid enhances fruit flavors and helps stabilize pH.
PHTHALIC ANHYDRIDE [ C8H4O3 ]
Phthalic anhydride (PA) is a white crystalline compound used to manufacture plasticizers, pigments, dyes and resins. One major consumer of PA is the phthalate plasticiser industry, the products of which are used to produce flexible plastic products such as wire & cable applications, hoses, pipes, coated fabrics, roofing membranes and swimming pool liners.
PA is used in the manufacture of unsaturated polyester resins (UPR) that are usually blended with glass fibers to produce fiberglass-reinforced plastics. Principal consumer markets are the construction, marine, and transportation sectors. PA-based alkyd resins are used in paints and lacquers that go in to architectural, machinery, furniture, and fixture applications.
In India, the pigments and dyes industry is a big consumer of PA because India is amongst the largest producers of organic pigments, particularly phthalocyanine blue, green and some high performance pigments. In addition, PA is used in the manufacture of products like herbicides, insecticides, insect repellents, fire retardants, polyester polyols, rubber scorch inhibitors, etc.
TCL is a pioneer in the manufacture of PA, having produced it for over forty years.
DIETHYL PHTHALATE
Diethyl phthalate (DEP) is a clear substance that is liquid at room temperature and is slightly denser than water with low volatility.
This synthetic substance is commonly used to make plastics more flexible. Products include toothbrushes, perfumes, automobile parts, tools, cosmetics, insecticides, aspirin, food packaging, toys, plastic packaging films, toiletries, and medical treatment tubing. It can be used as additive in polysulfide rubber to reduce shear strength and facilitates easy mixing for adhesives.
Since the compound is a suitable solvent for many organic molecules, it is often used to bind cosmetics and fragrances. DEP was reported as an ingredient in 67 cosmetic formulations, including bath preparations (oils, tablets, and salts), eye shadow, toilet waters, perfumes and other fragrance preparations, hair sprays, wave sets, nail polish and enamel removers, nail extenders, bath soaps, detergents, aftershave lotions, incense sticks, and skin care preparations.
DEP is used as a plasticizer for cellulose ester plastic films and sheets (photographic, blister packaging, and tape applications). In addition, DEP is used as a component in insecticide sprays and mosquito repellents, as a camphor substitute, as a plasticizer in solid rocket propellants, as a wetting agent, as a dye application agent for triacetate dyes, as an ingredient in aspirin coatings, as a diluent in polysulfide dental impression materials, and in adhesives, plasticizers, and surface lubricants used in food and pharmaceutical packaging.
