Glycerin Soap

What is Glycerin?

Glycerin or Glycerol is a simple 3 carbon compound. It is colorless, odorless, viscous and sweet liquid naturally occurring in plants. A Swedish scientist in 1779 accidentally discovered a fat that was called Glycerin by heating up an olive oil mixture. In mid-19th century people used Glycerin to make Glycerin soaps.

What are Glycerin soaps?

Soaps containing glycerol, an ingredient in fat or oil, are known as glycerin soaps. Because of their transparency, they stand out from other soaps. The addition of sugar and alcohol can cause the soap molecules to align, which is what gives the appearance of clarity. This is typically applied to non-remeltable homemade glycerin soaps.

In contemporary commercial soap production, the glycerin is typically extracted from the soap to be resold and utilized in a multitude of applications, including food processing, medicines, personal care items, and chemical intermediates.

How Glycerin soaps are produced?

A high-percentage alcohol solution is used to partially dissolve soap, which is then melted and heated repeatedly until the fluid takes on a transparent, jelly-like consistency. This process is known as glycerin soap making. A slow-cooked, hot-processed soap is mixed with alcohol and simmered with a sugar solution until it becomes translucent or clear. The simmered soap is then cooled in a freezer. When it comes to grating, melting, and boiling homemade or handcrafted soaps that still have glycerin left over from saponification, no further ingredients are needed; however, sugar or additional glycerin may occasionally be added.

Another way to make glycerin soap without re melting soap is to heat raw, homemade soap directly. Similar to conventional glycerin soap-making techniques, modern clear glycerin soap bases are made by mixing different glycerol and polyols with soap and other surfactants. These contemporary transparent soaps are frequently offered in large quantities to consumers for melt-and-pour soap crafts and have the advantage of being readily re-meltable.

Benefits of Glycerin Soaps

Glycerin soaps are natural and thus have many advantages for better skin and hair growth.

1: Doesn’t create Irritation

Pure glycerin soap is all-natural, vegan, and free of alcohol, perfumes, and other potentially irritating ingredients.

2: Avoids over drying of skin

Glycerin is a low-pH humectant that naturally gives skin more moisture when used as a soap ingredient. Compared to typical soap formulas, it is less drying, allowing the skin to retain its natural moisture and avoiding over-drying.

3: Cleanses the skin

Glycerin facilitates the skin’s absorption of other healthy nutrients and cleanses the skin without blocking pores. Its easy penetration into the skin allows it to fill in fine wrinkles and stimulate skin regeneration, giving the complexion a younger, bright, and supple appearance. Glycerin-based cleansers and soaps work particularly well on dry and sensitive skin types and are appropriate for mature, oily, and acne-prone skin types.

4: Nourishes Hair

The skin-improving properties of glycerin can help maintain a healthy, flake-free scalp and softer, more manageable hair in terms of hair care. Liquid and solid shampoo formulas can both contain glycerin as an ingredient.

How to apply Glycerin soaps?

Glycerin soap can be used on a daily basis as part of a regular skincare regimen. Glycerin soap, like other soaps, can burn or irritate your eyes if it gets in them. This shouldn’t be a problem as long as you wash your face carefully.

Side effects of using Glycerin soaps

While glycerin soap is safe for all skin types, extremely oily skin types may find the humectant properties unpleasant. You may find out how it will affect your skin by doing a patch test on a region of your skin that is especially oily.

Because glycerin absorbs water readily, a bar of this soap could not last as long as one made of traditional materials. Every time you use it, take it out of the shower to avoid it dissolving from accidental water spray.

How Glycerin soaps are made by own?

  • Put on safety glasses and gloves, then very slowly sprinkle the lye (never add water to lye) into the distilled water.
    Mix the lye solution with the vegetable or coconut plant oils.
  • Start heating the ingredients in a slow cooker or on the stove.
  • Incorporate the alcohol and liquid glycerin into the blend.
    Pour the mixture into the mold of your choosing and let it cool after the components have completely dissolved.
    The process of cooling down may require multiple days.
  • Making a big batch of soaps at once could be useful if you want to have additional bars on hand.


Precautions while making Glycerin soaps

  • The amount of any additive that may be safely added to a soap formulation should be known before hand. Adding too much of an additive can cause problems like chemical bond breaking or force the use of preservatives.
  • Only use heat safe equipment for making glycerin soaps.
  • In a melt and pour soap recipe, it is recommended to stay away from fresh ingredients like fruits, vegetables, or milk because they will ultimately go bad.

Cost of Glycerin soaps

The expense of pure components can also be an issue. Because they are less expensive to produce, synthetic-based soaps are offered at a discount. Pure glycerin soap may cost more than you want to spend on personal hygiene products. Although doing it yourself can save costs, it can take a lot of time.

End Note

Soaps containing glycerol, an ingredient in fat or oil, are known as glycerin soaps. Because of their transparency, they stand out from other soaps. The addition of sugar and alcohol can cause the soap molecules to align, which is what gives the appearance of clarity. This is typically applied to non-remittable homemade glycerin soaps. Because of its neutral pH, which balances our naturally somewhat acidic skin, it is safe and mild enough to use on all skin types, even sensitive skin. Above all, glycerin is a humectant by nature, which is just another word for a substance that draws moisture and leaves skin feeling nourished, silky, and soft.


1: Does Glycerin soap hypoallergenic?

Glycerin is thought to be safe and harmless however it doesn’t mean that it is hypoallergenic because the additional compounds in pure glycerin can sometimes cause allergies.

2: What is lye for soap?

Lye is an alkaline liquor used for washing and making soaps. It is an alkali metal hydroxide like sodium hydroxide or potassium hydroxide.

3:  What are the uses of glycerin?

A common chemical liquid in the food, pharmaceutical, and cosmetics industries is glycerin. Foods can be preserved, kept moist, and sweetened without adding sugar thanks to glycerin. It also acts as an antifreeze, laxative, and binding agent.

4: Is Glycerin safe?

Even in large amounts, glycerin does not present a health risk to humans, despite not being a necessary food item. The component is easily absorbed by the small intestine, and digestion proceeds without incident. Glycerin also has no effect on the secretion of insulin.
