Organic glycerin in food
Glycerin, also called glycerol or glycerine, is a sugar alcohol compound (C3H5(OH)3), comprising 3 carbons and 3 hydrophilic hydroxyl groups. It is a colorless, odorless liquid that is sweet tasting and very low in toxicity. As a food, it is categorized as a carbohydrate. In cosmetics, personal care and pharma, it is valued for its wide range of humectant and moisturizing properties, as well as bacteriostatic and preservative properties.
Glycerin is used in an amazing number of applications: As a humectant in lotions, creams and sunscreens; non-blood-sugar-elevating sweetener for foods (60% as sweet as table sugar); thickening agent in liqueurs, syrups, elixirs, & pie fillings; emulsifier for margarines; freshness retainer for baked goods; menstruum for herbal tinctures; tablet holding agent; fogging agent; de-icing agent; anti-drying agent for watercolors; and as a tobacco humectant. It is an important component in toothpastes, mouthwashes, skin care products, shaving cream, hair care products, glycerin soaps and other soaps, water based personal lubricants, snuff, rectal laxatives, eye shadow, lipstick, lipgloss, lotions and eyedrops. For topical care, it is an effective treatment for psoriasis, burns, bites, cuts, rashes, bedsores, and calluses. It can be used orally to eliminate halitosis and help with periodontal disease, as it is a contact bacterial desiccant.
Is organic glycerin safe
As with almost any substance, a small number of people have sensitivities or allergies to glycerin and it can be toxic if consumed in sufficient quantities. But as it’s typically used, to keep foods fresh or as a low-glycemic sweetener, glycerin is generally safe. It is not, however, calorie-free. In fact, glycerin contains slightly more calories than sugar—and it’s only about 60% as sweet, so you might need slightly more to get the equivalent sweetness. Also, as with sugar alcohols, consuming a lot of glycerin can produce a laxative effect, which may or may not be desired.
Here’s the bottom line on glycerin as an alternative sweetener: The main advantage is that glycerin does not affect your blood sugar. However, substituting glycerin for sugar will not reduce calories. And consuming it (or foods sweetened with it) in large quantities is not a recipe for good nutrition. I suggest that glycerin—like all forms of sugar and sugar substitutes—be consumed in moderation.
It really keeps coming back to the same thing: Try to build your diet primarily around whole foods—like fresh fruits and vegetables, legumes, eggs, dairy, fish and meat, nuts, and whole grains. Keep processed foods and sweet treats to a reasonable minimum—no matter how they are sweetened!
Glycerin organic solvent
Glycerol is usually produced as a byproduct of the transesterification of a triglyceride in the production of natural fatty acid derivatives. These derivatives are utilized in many areas from pharmaceuticals and food industry to alternative fuels, e.g., biodiesel, and thus as the production of glycerol raises its price decreases. In addition, glycerol has also promising physical and chemical properties. It has a very high boiling point and negligible vapor pressure; it is compatible with most organic and inorganic compounds, and does not require special handling or storage. Glycerol, as other polar organic solvents such as DMSO and DMF, allows the dissolution of inorganic salts, acids, and bases, as well as enzymes and transition metal complexes (TMCs), but it also dissolves organic compounds that are poorly miscible in water and is non-hazardous. Different hydrophobic solvents such as ethers and hydrocarbons which are immiscible in glycerol allow removing the products by simple extraction. Distillation of products is also feasible due to the high boiling point of glycerol.
The purpose of this study is to explore the scope and limitations of glycerol as alternative green reaction medium. Glycerol, which is a non-toxic, biodegradable, and recyclable liquid manufactured from renewable sources, shows similar properties as an ionic liquid and has a high potential to serve as green solvent for organic syntheses. This has led us to study its possible use as such in a variety of ways. Several non-catalytic and catalytic reactions using homogeneous and heterogeneous chemo- and bio-catalysts have been thus studied in glycerol. The unique physico-chemical nature of glycerol enables easy separation of the product by extraction or distillation together with catalyst recycling. These properties can also be translated into other processes which require non-aqueous polar solvents such as non-aqueous emulsions (Imhof and Pine 1997), as well as applications in microwave-promoted synthesis (Kappe 2004).
Organic glycerin benefits
Vegetable glycerin is touted as a product with numerous health benefits.
However, only a few benefits are supported by science — and the related studies tend to be few and small. Keep in mind that more studies are needed on its health benefits.
The following benefits have the most research behind them.
May Moisturize Skin
Vegetable glycerin is a popular skincare treatment because of its moisturizing power.
Research shows that applying glycerin to your skin may gradually improve its smoothness and suppleness. In fact, using creams containing glycerin may increase skin hydration in as few as 10 days (1Trusted Source, 2Trusted Source).
In one study, a cream made from glycerin was more effective than those made from silicone oil or hyaluronic acid at hydrating skin and preventing loss of moisture (3).
In another study, adding glycerin to a warm water bath was more effective at improving skin moisture levels and protecting against skin irritation than a warm water bath alone (4).
May Promote Skin Health
Vegetable glycerin may lead to better skin health by helping soothe skin irritation, protect against infection and promote wound healing.
Studies show that applying glycerin-containing products may protect your skin against irritants and microbes, as well as soothe inflamed or wounded skin (5Trusted Source, 6Trusted Source).
Moreover, vegetable glycerin may act as a barrier to safeguard your skin from the elements, including wind and cold (5Trusted Source).
Another study reports that vegetable glycerin may be more effective than a placebo at reducing sensations of smarting in people with eczema. However, it appears to have no effect on stinging, itching, drying or irritation (7Trusted Source).
May Reduces Constipation
Vegetable glycerin may provide some relief from constipation.
That’s because it can draw water into your gut. This has a laxative effect, which helps digested food move through your gut more smoothly.
For this reason, glycerin is often used as a suppository.
In one study, glycerin suppositories were significantly more effective at reducing constipation caused by pain-killing medication than other types of laxatives (8).
In another, a glycerin enema was 16.5% more effective at relieving constipation than a liquid soap enema (9).
May Boost Hydration and Athletic Performance
Glycerin may also boost hydration, which can improve your athletic performance.
Dehydration can greatly impair athletic performance, especially when sweat loss exceeds 2% of your body weight (10Trusted Source).
A good strategy to avoid dehydration is to drink enough liquids both before and during exercise. However, it can be impractical to drink during certain types of physical activity. In such a case, drinking plenty beforehand is key.
The problem with drinking large amounts in a short timespan is that a sizable portion of the fluid is generally lost through urine in the following hour.
However, in one meta-analysis, adding 2.4 grams of glycerin per pound of body weight (1.1 grams per kg) to water drunk before exercise increased fluid retention by 50% compared to water alone. Glycerin may also lead to small improvements in athletic performance (11Trusted Source).
In another study, a glycerin drink was also more effective than water or a sports drink at improving hydration in athletes who lost significant amounts of water through sweating during exercise (12).
How to make organic vegetable glycerin
If you enjoy making your own soaps and skin care products or just prefer natural beauty products, you probably know how versatile glycerin is. You can use it to mix your own soap, cleansers, moisturizers, shampoos, facial masks, and other personal care products because it’s an extremely effective cleanser, toner, and moisturizer. While you can purchase glycerin, you may enjoy making it yourself — particularly if you want a vegetable version that doesn’t use any animal fats. By mixing oils and lye, you can create a chemical reaction that forms vegetable glycerin, and as long a you have a candy thermometer, you don’t need to be a chemistry expert to get it done. Keep in mind that lye is an extremely caustic substance, though, so it must be handled with care
