Applications

In organic synthesis, glycerol is used as a readily available prochiral building block.

Glycerin can also serve as a substitute for petroleum based products. Glycerin derived epichlorohydrin and propylene glycol are substitutes for petroleum-based propylene.

Research laboratory usage

Glycerol is a common component of solvents for enzymatic reagents stored at temperatures below zero degrees Celsius due to the depression of the freezing temperature of solutions with high concentrations of glycerol. It is also dissolved in water to reduce damage by ice crystals to laboratory organisms that are stored in frozen solutions, such as bacteria, nematodes, and fruit flies. Samples are loaded into agarose gel electrophoresis mixed in loading buffers that mainly consist of glycerol; when the sample is injected into wells, the glycerol causes the solution to sink through the running buffer to the bottom of the well.

Pharmaceutical and personal care applications

Glycerol is used in medical and pharmaceutcal and personal care preparations, mainly as a means of improving smoothness, providing lubrication and as humactant or moisturiser. It is found in cough syrups, elixirs and toothpaste, mouthwashes, skin care products, shaving cream, hair care products, and soaps.

As a 10% solution, glycerol prevents tannins from precipitating in ethanol extracts of plants (tinctures). It is also used as a substitute for ethanol as a solvent in preparing herbal extractions. It is less extractive and is approximately 30% less able to be absorbed by the body.Fluid extract manufacturers often extract herbs in hot water before adding glycerin to make glycerites.

Used as a laxative when introduced into the rectum in suppository or liquid (enema) form; irritates the bowel and induces a hyperosmotic effect.

Glycerol is a component of glycerol soap. Other ingredients include, denatured ethanol, sodium castorate (from castor), sodium cocoate, sodium tallowater, sucrose/sugar, perfume and water. This kind of soap is used by people with sensitive, easily-irritated skin because it prevents skin dryness with it’s moisturising properties. It is possible to make glycerol soap at home.

It is also used in de- icing/anti-icing fluids normally mixed with alcohol or propylene glycol or both and water

In motion-picture production, glycerol is used as a non-evaporating substitute for perspiration on actors. It is also used in the formulation of some types of stage blood.

Potential uses

Some potential uses for glycerol include the following:

  • Nicotine carrier for use in electronic cigarettes
  • Glycerine acetate (as a potential fuel additive)
  • Compost additive
  • For Tincture extraction and preservation of Essential oils and chemicals from herbs.
  • Citric acid production
  • Cosmetic bonding agent for makeup, including: eye shadow, lipstick, lipgloss, and lotions and also including eyedrops as well
  • Can be used to moisten hookah tobacco if it’s too dry or bought as “dry” tobacco..
  • Conversion to propylene glycol
  • Conversion to ethanol
  • Glycerol may be used as antifreeze for plants, if mixed with water in a 10% solution. It is believed to be effective at temperatures near –18?C
  • Glycerin may serve as a source of energy used in waste water treatment plant digesters

Preserving Tree Branches

  1. Cut branches when color begins to change, before the leaves are completely tinted. (Fully turned leaves are too dry and brittle.) Beech, oak, wild apple, mountain ash and copper beech are well suited for this method of preservation.
  2. Use a solution of 2 parts water to 1 part glycerine. The amount needed depends on the size of the branches. (The stems must be in liquid to a depth of 3 to 4 inches.)
  3. Trim off any small twigs at the bottom of the branch. Slit the bottom of each stem with a sharp knife to 3 or so inches.
  4. Next, bruise the stalks with a hammer.
  5. Arrange the branches in a container of the water/glycerine mixture and place in a cool room for a week to ten days. The leaves will last for years! Makes great centerpieces and displays.

What is Perfumers Alcohol and how is it used

Perfumers Alcohol is a special formulation which can be used by both professionals and amateurs who wish to make perfumes. It allows the simple addition and blending of essential oils and fragrances to produce crystal clear solutions.

Perfumers alcohol is also used in the production of DIFFUSER OILS.

The blended solutions remain clear and free from cloudiness.

The 3 main ingredients of perfumers alcohol are:

  1. Ethanol (denatured) –Alcohol which is the main carrier for the fragrance oils. This evaporates quickly as it is warmed by skin temperature releasing the fragrances evenly over the surface.
  2. Isopropyl myristate – used in preparations where good absorption is desired.
  3. Monopropylene glycol – a cosolvent which allows the fragrance oils to be solubilised in the alcohol carrier. This helps to control the evaporation of the alcohol so that it does not flash off too quickly.

 

How to use Perfumers Alcohol

Using these perfumery methods will help you take your homemade fragrances to a more professional level, in fact, if you use these techniques, you could actually sell your end result! The basic professional perfume making process is the same as the amateur perfuming process, but the materials are not.

  • Perfumer’s alcohol makes a great solvent for even the most resinous oils. It is what all commercial perfumes are made with, except some boutique brands that make roll-on scented oil or solid perfume.
  • Use different fragrance materials, not only essential oils. There are many more fragrance materials available other than essential oils. If you only use essential oils, you limit your perfume blending possibilities. It’s like wanting to paint a mural, but only having red and yellow paint.
  • In addition to essential oils, there are also absolutes, fragrance oils, and isolated aroma chemicals, all supplying scents that can’t be produced with essential oils.

Absolutes are stronger and smell more like the plant than essential oils, and are used extensively in perfumery. Some plants are too delicate to be pressed or steam-distilled; making an essential oil out of them is impossible. Jasmine is one of these plants. The absolutes are expensive, but a little goes a long way. They are much more concentrated than essential oils.

Fragrance oils, despite what you may have heard, aren’t merely cheap substitutes for essential oils. They are a completely different spectrum of scent, containing a combination of absolutes, essential oils, and synthetic aroma chemicals. Fragrance oils give you access to scents that you can’t get naturally, for example strawberry, peach, and watermelon.

Fragrance oils also have the benefit of being skin-safe (as long as you get cosmetic grade.) If you want to create an entire line of perfume and bath and body products in a favourite scent, you can use the same skin-safe fragrance oil to scent all of them.

Aroma chemicals are isolated fragrance molecules that are either synthetically produced or refined from plant sources. For example, the compound vanillin is what gives vanilla its characteristic odour and flavour. Artificial vanilla flavour is usually pure synthetic vanillin. Natural vanilla has many more compounds than just vanillin, which is why it tastes better!

Strawberry fragrance oil, one of the most sought-after scents in the cosmetic and fragrance industry, is a combination of strawberry aldehyde (Ethyl methylphenylglycidate) and other compounds to round out the scent.

Using Fixitives

Use fixatives in your perfume. If you’ve experimented with essential oils such as mint and bergamot, you’ve probably noticed that they disappear within an hour. This is because they evaporate quickly, aided by the heat of your skin.

Fixatives are a way to help make fragrances last longer. They are natural or synthetic substances that enhance scent and slow down the evaporation of scents that tend to disappear. Why do fixatives work? They are very high in scent molecule count, often with no distinct odour of their own. They just blend with the key fragrance and make it seem stronger.

For example, musk, a traditional fixative, can enhance the scent and make its perceived strength stronger. It only takes a small amount for a big effect – with effective use of musk, you won’t smell it, but the entire perfume will last longer and smell stronger. (Musks have been synthetic since the 1970s due to cruelty and endangerment laws.)

Plant fixatives include many resinous, sticky oils and absolutes like benzoin, frankincense, vetiver, and orris. They often have an earthy scent that “deepens” a blend. With a little experience, you’ll have a good idea of what fixatives can enhance and give subtle character to your perfumes.

As you can probably tell, using professional methods are not much more difficult than what you may have tried already. However, I must say that the techniques given here are more expensive than the home-brewed. They require the use of specialized, more costly materials.

Using perfumer’s alcohol and absolutes are only for people who are somewhat serious about perfume, but it is a fun, fascinating activity. It is definitely possible to get started cost-effectively; Many botanical absolute suppliers have samples that you can use at first.

It’s also a good idea to try absolute dilutions before going for the real thing. Dilutions will help you work with the absolute without becoming overwhelmed by the un-concentrated fragrance, and they are also less expensive. Most dilutions are 3% – 5% absolute in jojoba oil, similar in strength to essential oils.

Magnesium is an essential mineral for the body. Magnesium is a required cofactor for many enzyme systems. It is required for protein synthesis and for both anaerobic and aerobic energy generation and for glycolysis, either indirectly as a part of magnesium-ATP complex or directly as an enzyme activator (Bronzetti et al., 1995; Food and Nutrition Board, 1997).
Magnesium plays a multifunctional role in cell metabolism, particularly at the level of key phosphorylations. The role of magnesium in cell division is also well recognised and it has been suggested that cell division of various cell types is highly dependent on the availability of extracellular magnesium (Rubin, 1975).
In addition magnesium may play an important role in regulating blood pressure, bone and muscle growth and helps to reduce the development of atherosclerosis, cardiac arrhythmias, myocardial damage and arterial hypertension.
Magnesium deficiency has been linked to several disease states involving the cardiovascular, skeletal, gastrointestinal and central nervous systems. The most frequent causes of hypomagnesemia are reduced intake, impaired intestinal absorption, renal loss and genetic diseases.

Magnesium chloride BP in Medical industry

Magnesium chloride is an electrolyte replenisher and a pharmaceutical necessity for hemodialysis and peritoneal dialysis fluids. It is used as a source of magnesium in the treatment of hypomagnesemia in cattle, and as a chemical defibrillator in cardiopulmonary resuscitation.
Magnesium chloride acts as a laxative, an antacid and a anticonvulsant. It increases osmotic gradient in small intestine, which draws water into intestines and causes distention. These effects stimulate peristalsis and bowel evacuation. In antacid action, it reacts with hydrochloric acid in stomach to form water and increase gastric pH. In anticonvulsant action, magnesium chloride depresses CNS and blocks transmission of peripheral neuromuscular impulses.

MAGNESIUM CHLORIDE IN MARINE AQUARIUMS:

Magnesium chloride hexahydrate is for adding magnesium to sea water. Severely low values of magnesium (900 mg/L or below) can cause low pH values and an inability to maintain proper alkalinity and calcium values. If magnesium becomes too low, coral growth will stop and followed by a decline in coral health. Carbonates and calcium are essential for all growth of corals, coralline algae, clams and invertebrates. Maintaining the correct magnesium values is very important and is indirectly responsible for coral and coralline algae growth by making it possible to maintain correct calcium, alkalinity and pH values. The magnesium content must often be increased, as shortfalls in the content can arise for various reasons. The normal magnesium content is around 1.30 ??? 1.40 mg/litre (1300???1400 ppm). To increase the magnesium content you need magnesium chloride hexahydrate or a mixture of magnesium chloride and magnesium sulphate (ratio of 7:1).

How to dose aquarium with magnesium chloride

50g will raise Magnesium levels by approximately 60ppm in 100 litres of salt water. It is not recommended to increase Magnesium levels by more than 60ppm per day. Simply mix the required amount into a few litres of Reverse Osmosis Water, once dissolved, slowly add to your tank in an area of high flow, preferably over a period of an hour. Alternatively add to your evaporation top up water and top up as normal.

Health & safety

Not a hazardous substance or mixture according to Regulation (EC) No. 1272/2008.
