Product Uses

Pharmaceutical Uses

Some of the roles lactose performs in drugs are:

It acts as a filler: Sometimes the active ingredient in a drug is present in very small quantities. Fillers like lactose bulk up the drug, helping it flow better. Fillers also make it easier to measure the active ingredient in drugs.
It acts as a binder: Lactose binds pills together by helping the other ingredients in a tablet mix and stick together.
Food Processing
Lactose is used in several facets of food processing. Edible lactose that’s used in food processing is also mostly produced from whey.

It’s used in seasonings and baked goods due to its ability to carry colors and flavors well. It’s also added to foods and edibles like ice cream, skim milk, condensed milk, dry soups, coffee creamers, chocolate and candies, meat products, and canned fruit and vegetables.

When added to food, lactose may reduce cost and regulate sweetness.
Fermentation
Lactose is fermented to produce foods like cheese, yogurt, kefir, and acidified (sour) milk. Lactose is also fermented to produce lactic acid, which has a number of uses in the pharmaceutical, cosmetic, and food industries.

The process of fermentation involves adding lactic acid bacteria (and less commonly, yeast) to milk or to a milk product.
Bacterial Identification
In the clinical laboratory, the ability of bacteria to ferment lactose might help differentiate which bacterial species is causing an infection, such as food poisoning. For example, Escherichia coli ferments lactose while most Salmonella species do not.
Cutting Agent
Lactose is commonly used as a cutting agent for illegal recreational drugs. Cutting agents are chemicals or drugs that are used to dilute and add bulk to recreational drugs.

The use of cutting agents is prevalent in illegal drug production, and the substances used for this process are typically less expensive than the recreational drug itself.

Product Benefits

Lactose has some health benefits for babies. Human breast milk is composed of 7.2% lactose, and this sugar provides up to half of the energy needs of breastfeeding babies.

The lactose found in human milk has a beneficial effect on the development of microorganisms that live in the digestive tract of babies. It also helps babies absorb calcium better.

Product Side Effect

- Cellulaze side effects include: Bruising: virtually all patients experience some degree of bruising. This is managed with compression and supplements like Arnica Soreness: since the treatment is applied to the skin itself, there is a sensation of general soreness to the area that lasts a few days to weeks Firmness: the skin has been treated to cause firming and thickening, so this sensation is a normal consequence of the treatment There is a risk of infection as with any surgical procedure, but otherwise side effects are limited.

Air and Water Reactions:

Water soluble.

Reactive Group:

Alcohols and Polyols

Reactivity Profile:

Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
