glycerin and rosewater for face

Glycerin and rosewater are prominent for hydrating and healing abilities.

These innate lock moisture over the outer layer of the skin. Due to its versatile nature, it easily gets absorbed by your skin. According to  humectants like glycerin, lecithin and rosewater attract water to the skin.

Enticing properties residing in these two ingredients allured cosmetic industries to incorporate them it into their beauty products.

Benefits of glycerin and rosewater for face have been documented by many beauty experts and ancient people.

Glycerin is a colorless viscous liquid and sweeter in taste. While rose water is also colorless and is made by steeping rose petals. Both are non-toxic and have been used in cosmetic and food industries.

12 Awesome Benefits of Glycerin and Rosewater for Skin


Comparatively, glycerin is sticky than rosewater. You can either use them separately or blend them and topically apply over the skin.

Else you’re free to prefer any innate home ingredient as a combination. Now let’s take a note on how rosewater and glycerin for skin are beneficial.

#1 Rosewater and Glycerin for Acne


Phenylethanol housed in rosewater is an astringent, which thwarts acne-causing bacteria and reduce pimples. Antioxidant and anti-inflammatory properties of rosewater help to reduce inflammation caused by acne.

Glycerin is non-comedogenic in nature, which makes it a perfect remedy for treating acne lesions.

Lemon juice is packed with an antibacterial ability that helps to restrain acne causing bacteria.

To make the recipe effective, beauty experts recommend blending these ingredients.

How to Use: Take required amount of rosewater, glycerin and add few drops of lemon juice to it. Wash your face and apply the toner all over the face.

Limit the use of lemon juice if you’ve dry skin.

#2 Glycerin and Rosewater for Skin Lightening


Increasing levels of pollution and dirt give a tough competition for your skin. Wipe them out using rosewater and glycerin solution.

Various factors influence the formation of dark spots. UV rays, skin ailments, dry skin and hormonal imbalance are held responsible for this skin disorder.

Bleaching ability of lemon juice, the moisturizing activity of glycerin and cleanse property of rosewater combine to work for skin fairness.

How to Use: Cleanse your face to remove impurities. I prefer gram flour mask for removing dirt and dead cells.

Mix required an amount of rosewater with glycerin and apply it over the face using a cotton ball. Leave it to dry naturally.

Note: These ingredients will effectively reduce skin complexion and cleanse impurities. But, don’t expect this remedy to change your brown skin to radiant skin within weeks.

#3 Rosewater and Glycerin Toner


To reap exceptional benefits of these two ingredients, a skin toner will be helpful. You can get this toner at the local drug store or make it at home.

Repeated application of this toner will reduce wrinkles, rejuvenate skin, moisturize and makes the skin radiant.

How to Use: Mix 1-2 cups of rose water with a 1/4th cup of glycerin. After mixing thoroughly pour the solution into a spray bottle for future use.

#4 Aromatherapy


Rosewater essence is regarded as mild sedative and anti-depressant. So it’s believed to reduce stress and increase your focus.

According to researchers, stress is one of the main triggers of eczema, acne, and psoriasis.

How to Use: Spray your room with rose water before sleeping. You can also apply this toner over the face and on the pillow to burst stress and to have a good sleep.

Convert glycerin waste into profit

Glycerin is a clear, colorless, viscous liquid derived primarily from natural and petrochemical feedstocks. Traditionally, glycerin has been found in foods, pharmaceuticals and foods (USP grade glycerin) for coatings, coatings and other industrial types of applications (industrial grade glycerin).
With the increase in renewable fuel production over the years, especially the emergence of biodiesel
Excessive amounts of glycerol. This type of glycerin, also known as the "crude glycerin" biodiesel by-product, has a purity of about 80%. It produces one-tenth of a gallon of biodiesel. While the demand for glycerol remains generally stable, oversupply in the global market has caused price volatility across the industry. This abundant supply of crude glycerol is a direct result of increased biodiesel production. If not improved, this impure glycerin form must be disposed of in a certain amount according to the US Environmental Protection Agency (EPA) or sold on the open market at the minimum amount. Water, methanol and salt content.
The current price fluctuations in glycerol, mainly from biodiesel production, have produced dramatic changes in the glycerin refining sector. The demand for refined glycerin, technical grade and higher, has risen and started to stabilize. It is for this reason that biodiesel equipment manufacturers have been focusing on glycerin refining to help biodiesel plants use glycerin to achieve greater profits, thereby avoiding high disposal costs or minimally coming back from crude glycerin. . By further refining glycerol to >97% purity range, plants can now sell their glycerin for higher returns and create a new profit center for them.
Biodiesel equipment manufacturers are extremely efficient and profitable biodiesel plants. Their clients learn how to generate profitable markets by refining glycerol in the field instead of selling crude glycerin in the open air. SRS's glycerin refining system produces >97% industrial grade glycerol, rather than the average of the biodiesel industry, with a purity range of 80% to 90%.

Glycerine Distillation and Refining

Glycerine Spent Lyes Pretreatment

Glycerine content of fat hydrolysis wastewater and manufacturing waste water reaches about 10-15%. Generally adopting methods of chemical decontamination, ion exchange and electrical purification.

Spent Lyes Concentration

Based on the principle of evaporation, content of glycerine reaches 80-90%, to yield crude glycerin.

Glycerine Distillation and Refining

Crude glycerine is distilled in distillation column to make refined glycerine, after decolorizing and bleaching to make finished products refined glycerin. Mixed vapour out of the top of distillation column is further separated into 2nd grade glycerine.


Fatty Acid Distillation

Natural fatty acids can be extracted from animal oil, palm oil, palm kernel oil and coconut oil. Main products include mixed fatty acid, crude oleic acid, crude linoleic acid, crude stearic acid, hydrogenated stearic acid, palmitic acid and etc.

Oil and Fat Pretreatment

Pretreatment is designed to remove impurities. Whether pre-treat or not depends on the content of pectin, wax and other harmful substance except triacylglycerol when using vegetable oil as raw materials to produce fatty acids. Common pretreatment process includes hydration degumming and bleaching. Phospholipids can be removed by means of adding a small amount of phosphoric acid and the remaining impurities will be removed under the adsorption of bleaching carclazyte.

Oil and Fat Hydrogenation

Oil and hydrogen react at a certain pressure and temperature, in order to reduce the unsaturation of oil. The hydrogenated oil will yield more stable products in the further processing including catalyst filtration and avoid the fatty acids hydrogenation step.

Oil and Fat Splitting

Adopting non-catalytic countercurrent hydrolysis at high pressure and temperature, oil splitting into fatty acid and glycerol. This method has the feature of high hydrolytic degree.

Sweetwater Pretreatment

Chemical treatment of spent lyes, on the contrary of sweet water, is unavoidable and is carried out in a continuous, fully automatically controlled unit.

Sweetwater Concentration

Based on the principle of evaporation, content of glycerine reaches 80-90%, to yield crude glycerin.

Glycerine Distillation and Refining

Distillation is based on a packed tower where glycerine is distilled, fractionated to separate both heavy and light boiling impurities and condensed.

Fatty Acids Distillation

Distillation tower is equipped with structured packing to fractionate heavy and light boiling impurities and to ensure that fatty acids are distilled at the lowest possible temperature. Condensation can be carried out inside tower over packing with cooling of an external pump around or outside the tower in shell and tubes condensers.

Fatty Acids Fractional Distillation

According to different boiling points of different fatty acids at the same pressure, separate mixed fatty acids of different carbon chain to meet product demand.

Fatty Acids Hydrogenation

Fatty acids mixed with catalyst, entering into hydrogenation tower, then analyze the iodine value of product to determine whether the hydrogenation is completed.

An Innovation in Glycerin Purification

The global increase in biodiesel production has led to a marked increase in world glycerin production. Glycerin is produced as an approximately 11 percent byproduct in the transesterification of triglycerides, which are the predominant feedstock material for producing biodiesel. Glycerin remains one of the most versatile and valuable known chemicals and has a wide variety of uses and applications. The added production of glycerin by the biodiesel industry has created a supply that has encouraged the development of new industrial applications for this material. For example, recent reports tout glycerin's ability to be used as a raw material building block for the production of high-volume industrial chemicals such as propylene glycol, epichlorohydrin, acrylic acid and polyhydroxybutyrate. 

Purification is required to transform crude glycerin to a usable state for existing or emerging uses. The purity requirements for the emerging applications of glycerin vary, and are often intermediate to the crude and refined grades previously established for the classical applications. The salt content in crude glycerin, stemming from the use of homogeneous alkaline catalysts, often ranges from 5 percent to 7 percent, which makes conventional techniques cost intensive. This suggests that for future glycerin markets a new low-cost purification strategy may be more cost-effective than conventional routes . 

The glycerin produced in the transesterification of triglycerides reaction is a crude grade. Almost all biodiesel production today involves homogeneous alkaline catalysts such as sodium methylate. The transesterification of triglycerides with methanol generates a methyl-ester phase and a glycerin phase. Impurities such as catalyst, soap, methanol and water are preferentially concentrated in the glycerin phase. The glycerin phase is typically neutralized with acid and the cationic component of the catalyst is incorporated as a salt. 

For example, sodium chloride is formed in the neutralization with hydrochloric acid of glycerin containing sodium methylate. Catalyst usage rates vary across the industry, but it is common to find crude glycerin issued from biodiesel production with a salt content of 5 percent to 7 percent. It should be noted that heterogeneous processes using enzyme and solid metal-oxide catalysts are promoted as alternatives to homogeneous alkaline catalysts.  Nevertheless, even in heterogeneous transesterification processes, impurities in the natural feedstock materials tend to accumulate in the glycerin phase and therefore, purification may still be required. 

Conventional Techniques for Purifying Glycerin
Distillation is the most commonly practiced method for purifying glycerin. The advantages of the distillation process are well known. Namely, it is an established technology that produces high-purity glycerin in high yield. However, the distillation of glycerin is an energy-intensive process . Glycerin has a high heat capacity, which demands a high-energy input for vaporization. 

Classical ion-exchange techniques have long been applied to glycerin purification. However, the high salt content of glycerin issued from biodiesel production makes classical ion-exchange uneconomical for this application. Specifically, the chemical regeneration cost for the resins becomes exceedingly high when salt contents approach the 5 percent- to 7 percent-range commonly found in the biodiesel industry.

What is liquid glycerin?

Glycerin is the natural form of glycerol. That is, it is mostly glycerol, but has some other components, depending on the source and method of processing. For many commercial uses, this does not make any difference, but it can be purified to essentially pure glycerol for chemical processes.


The fats and oils which are used to make soap are esters of glycerol which are broken down by NaOH to give the sodium salt of the carboxylic acid (soap) and glycerol, which is collected as separate layer. (The different sources of fats and oils will give different impurities.) As both layers are very viscous, separating them is tedious. It is thus amusing to to have soap producers boasting “with added glycerin!” meaning less well separated. “Hand-crafted” soaps typically have most of the glycerin left in, because the backyard producers do not have the technology of the big soap makers, who can produce glycerin of sufficient purity to be sold at a modest price for food and cosmetic use.


Glycerol is also produced when making biodiesel, where methanol CH3OH is used instead of NaOH. Thus it is essentially a low value waste product from two major industrial processes, and produced in far greater amounts than commercial uses demand. Thus many end processes are essentially ways of trying to get some small value from a waste, e.g. by burning it for energy or adding it to cattle feed.

Glycerin's benefits for hair


Glycerin is a carbon compound and humectant which mean it attract the water from the surroundings. In the chemistry it is often called as the glycerol.


Glycerin is widely used in skin and hair products. It is added to soaps, shampoos, moisturizers and lotions. Glycerin is an excellent ingredient in cosmetics due to perfect ability to absorb water from its surroundings. Along with skin, glycerine is also very useful in treating hair.


There are many wonderful benefits of glycerin for your hair:




  1. Natural moisture retention. Glycerin makes the skin layer improved by making the scalp moisturized. In order to get rid of dehydration the most preferable season to use products with glycerin is winter.

  2. Maintenance of length. Drying out and breaking out of hair will be reduced with glycerin. Thereby, hair growth will be optimized. It can reach to the adequate length by faster grow.

  3. Eliminating itch. If you want to get itch free scalp you should apply glycerin over your scalp on a regular basis.

  4. Reducing dandruff. Glycerin has soothing properties for creating cooling effect on skin layer. That is why dandruff, flaky and dry scalp will be eliminated easily over your skin.

What is glycerine and how it is used?

Glycerin is a sweet-tasting, neutral, colorless liquid which can turn into a paste when it freezes and has a very high boiling point. While it is flammable, it has a flammability rating of 1 which is very low. It can be easily dissolved in alcohol and water but not in oils. It is an excellent solvent, and many different compounds can be easily dissolved into it.


Glycerin is highly hygroscopic and can easily absorb water from the air. As a result, when 100% glycerin is placed on the tongue, it can result in blisters as it is very dehydrating. However, when it is mixed with water, it can help soften the skin. This is the reason due to which glycerin is so abundantly used in the cosmetics industry.


Moreover, it is also used for manufacturing anesthetics, cough remedies, ear infection drugs and for making capsules. It is also used very commonly for manufacturing soaps, as a freeze control and as an intermediate in the production of chemicals, like polyester polyols. Silver Fern Chemical, Inc is your one-stop destination for buying glycerin and a wide range of other industrial chemicals in bulk quantities. With a well-developed network throughout the US, it is one of the most reputed chemical suppliers in the country.
