Soap Making Cold Process - The process of making transparent soap has been widely mentioned in research journals, both domestic and foreign journals. IPB (University in Indonesia) students and their supervisors tried various formulations of transparent soap preparations to get the best products based on certain criteria. Some of them make transparent soap which uses patchouli oil as an acne remedy and galangal extract as an anti-fungal active ingredient. In this article we provide a collection of transparent soap recipes that you can try yourself at home.

Soap Making Cold Process - Recipes and transparent soap formulas that produce high quality transparent soap products are sought after by soap manufacturers. To get a good transparent soap formulation is not easy. Research, trial, and trial error are needed many times to get the effective recipe for transparent bath soap. But the results of hard work will not be in vain, because the price of quality products will be accepted by the public.
One popular transparent soap recipe is patchouli oil transparent soap formulation as an acne remedy. Patchouli oil contains active patchouli compounds which are believed to reduce the formation of acne on the skin. You can read research journals related to the preparation of transparent soap with patchouli oil here. But not everyone likes the scent of patchy patchouli oil. For that reason, the combination of transparent soap formula as aroma therapy continues to be developed by transparent soap producers.
+ Transparent Soap Shape and Color
Soap Making Cold Process - The shape and color of solid transparent soap is currently diverse. The main reason for this is to rejuvenate the market so that it is not saturated. You can find transparent soap in the form of rods, rounds, ovals. Transparent soap colors are also varied like green, orange, red, and other metallic transparent soap colors. See the following examples of transparent soap images.
+ Transparent Face Soap or Tranparan Bath Soap
Transparent soap is generally used for face or face, but does not rule out the possibility of being used as bath soap. The content of alcohol in transparent soap formulas makes the soap more effective for removing acne and is used as facial whitening. But for some people, especially those with sensitive and hypersensitive skin, transparent soap can be dangerous for them because alcohol can be irritant or cause skin irritation. As an alternative, people with sensitive skin can still use transparent soap which is a type of transparent soap without alcohol or non-alcoholic transparent soap which is likely not cheap. Next we explain the ingredients and recipes / formula for making transparent soap.
+ Transparent Soap Making Materials
The standard transparent soap making material is coconut oil and hydroxide solution (NaOH). In addition, it can also be formulated with herbal active substances such as lemongrass, patchouli, virgin coconut oil (Virgin coconut oil, VCO), honey, galangal, green tea, aloe vera, papaya or papaya, seaweed and other natural ingredients so that it becomes herbal soap. The use of transparent soap has now expanded and has come out of its basic function as a body cleanser. You can use transparent soap as a souvenir or gift for your friends. The following is an explanation of the ingredients in soap making and its function.
- Oil and Fat
Oil is a triglyceride that is generally obtained from plants, whereas fat is a triglyceride extracted from animals. Types of oil that can be used in the process of making soap are soybean oil, coconut oil, palm oil, castor oil, corn oil, and other oils. The following is a tabulation of the types of vegetable oils and fatty acids that are dominant in them. Oil becomes the raw material in the Recipe / Formulation of Transparent Soap Making.
Table of the dominant fatty acid content in some types of oil
| No. | Oil Type | Dominant Fatty Acids | Amount |
|---|---|---|---|
| 1. | Coconut Oil | Lauric Acid | 44 - 53 % |
| 2. | Palm Oil | Palmitic Acid | 40 - 46 % |
| Oleic Acid | 39 - 45 % | ||
| 3. | Castor Oil | Risinoleic Acid | 86 % |
| 4. | Corn Oil | Linoleic Acid | 56.3 % |
| Oleic Acid | 30.1 % | ||
| 5. | Soybean Oil | Linoleic Acid | 15 - 64 % |
| Oleic Acid | 11 - 60 % |
- Difference between Vegetable and Animal Fats
The basic difference between vegetable fat and animal fat is:
- Animal fats contain cholesterol, while vegetable fats contain phytosterol.
- Saturated fat content in animal fat is smaller than vegetable fat.
- Oil color
Dyestuffs in oil and fat are divided into two: natural colors and colors due to oxidation or degradation of the chemical components contained in oil. Natural dyes are naturally found in the ingredients and are extracted along with oil in the extraction process, such as alpha and beta carotene, xanthofil and anthocyanin. These dyes cause yellow, brownish yellow, greenish and reddish. The color due to oxidation and degradation of the chemical components contained in oil include: dark color caused by oxidation of tocopherol (vitamin E).
- Odor (odor and flavor) Oil
Fishy smell in oil or fat is caused by the interaction of trimethyl amine oxide with double bonds of unsaturated oil. Trimethyl amine is derived from the breakdown of the C-N bond from cholin in the lecithin molecule and this C-N bond is broken down by an oxidizing agent such as a peroxide group in fat, thus producing trimethyl-amine.
Odor and flavor in oil are generally caused by non-oil components, for example the typical smell of palm oil is caused by beta-ionone, while the typical smell of coconut oil is caused by nonyl methylketon (Ketaren, 1986). Besides naturally occurring odor and flavor also occur due to the formation of short-chain fatty acids as a result of decomposition of oil or fat damage.
- Sodium Hydroxide (NaOH)
Sodium hydroxide (NaOH) is often referred to as caustic soda or soda which is an alkaline compound that is alkaline and can neutralize acids. NaOH is white crystalline with moisture-absorbing properties. Sodium hydroxide reacts with oil to form soap called saponification. This soda ingredient is the main ingredient in the Recipe / Formulation of Transparent Soap Making.
- Stearic Acid
Stearic acid is a long chain (C18) monocarboxylic which is saturated because it has no double bond between its carbon atoms. Stearic acid can be liquid or solid. In the process of making soap, stearic acid serves to harden and stabilize the foam.
- Ethanol
Ethanol (ethyl alcohol) is liquid, clear and colorless, is an organic compound with the chemical formula C2H5OH. Ethanol in the soap making process is used as a solvent because of its solubility in water and fat.
- Glycerin
Glycerin is a by-product of hydrolysis reactions between vegetable oils and water to produce fatty acids. Glycerin is a humectant that can function as a moisturizer on the skin. In moderate atmospheric conditions or in conditions of high humidity, glycerin can moisturize the skin and be easily rinsed. Glycerin is clear liquid, odorless, and has a sweet taste.
- Coco Dietanolamida (Coco-DEA)
Coco-DEA is a dietanolamide made from coconut oil. In cosmetic preparation formulas, DEA functions as a surfactant and foam stabilizer. Surfactant is a surface tension reducing active compound that is useful for uniting the oil phase with the water phase.
- Sodium Chloride (NaCl)
Sodium chloride (salt) is a white crystalline, colorless and low hygroscopic material. The addition of NaCl is not only for soap foaming, but also to increase the electrolyte concentration to match the decrease in alkaline amount at the end of the reaction so that the ingredients of the soap maker remain balanced during the heating process. Salt is also known as an ingredient that suppresses the growth of microorganisms in the Recipe / Formulation of Transparent Soap Making.
- Sugar
White crystalline sugar. In the process of making transparent soap, sugar works to help form transparency in soap. Adding sugar can help the development of crystals in soap.
- Citric Acid
Citric acid has the form of white crystals. Serves as a chelating agent, which binds to oxidizing metal ions, so as to prevent oxidation of the oil due to heating. Citric acid can also be used as a preservative and pH regulator.
- Dye
Dyes are added to the soap making process to produce colorful soap products. The coloring material used is coloring material for grade cosmetics. Coloring is an additional ingredient in the Recipe / Formulation of Transparent Soap Making.
