Method for manufacturing natural liquid soap {Method for manufacturing natural soap}

The present invention relates to a natural liquid soap manufacturing method.

Recently, as users are interested in environmental issues, interest in natural soaps is increasing.

Natural soaps are soaps that use base oils extracted from natural plants instead of synthetic fragrances and do not contain chemicals such as preservatives, thickeners, curing agents, and surfactants.

General soaps contain many artificial additives such as synthetic detergents, artificial colors, synthetic fragrances, etc. to enhance the washing action.

Including such artificial additives may cause itching and skin diseases.

Natural soap does not irritate the skin because it smells of natural substances and base oils.

In addition, recently, natural soaps suitable for atopy, dryness and oily use may be manufactured according to skin properties, and depending on the skin condition, it may be possible to utilize the characteristics of whitening, moisturizing, cleaning, anti-aging, exfoliation and soothing effect.

Natural soap is largely manufactured by MP (Melt & Pout) method or CP method.

MP soap is prepared by dissolving a soap base prepared in advance and adding a moisturizer, natural powder, and base oil suitable for skin properties to pour the mold into a mold.

However, MP soaps are difficult to say true natural soaps because they use factory-based soap base (TEA) triethanolamine containing triethanolamine (TEA).

CP soaps are prepared by mixing and stirring base oils such as coconut oil, palm oil, sodium hydroxide and water (distilled water) without a soap base to produce natural glycerin during saponification, and aged for a predetermined period of time to cure in the mold.

In general, the preparation of CP soap requires a aging period of four to six weeks, which is the time during which the sodium hydroxide, which is essential in the saponification process, is completely neutralized with glycerin and the soap hardens.

As described above, glycerin is produced by the chemical reaction of sodium hydroxide, base oil and water when preparing natural soap, and when the humidity is high when solidified natural soap is used, solid soap melts due to glycerin.

For this reason, research is being conducted to provide a liquid soap, but when liquefying the solidified natural soap there is a problem that the glycerin and the aqueous phase layer is separated and does not act as a soap.

Korea Patent Registration 10-1911645

In order to solve the above problems of the prior art, it is proposed a natural liquid soap manufacturing method that can stably combine the glycerin and the aqueous phase in the liquefaction process of the solidified soap.

1 is a flow chart of a natural liquid soap manufacturing process according to an embodiment of the present invention.
2 to 5 is a view showing the configuration of a solid natural soap manufacturing apparatus according to an embodiment of the present invention.

As the present invention allows for various changes and numerous embodiments, particular embodiments will be illustrated in the drawings and described in detail in the written description.

However, this is not intended to limit the present invention to specific embodiments, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

Figure 1 illustrates a natural liquid soap manufacturing process according to an embodiment of the present invention.

Natural liquid soap according to the present embodiment is prepared by liquefying the solid natural soap that is aged at low temperature.

Referring to Figure 1, by mixing the base oil, water and sodium hydroxide to prepare a solid natural soap is completed saponification (step 10).

Here, the base oil may be coconut oil or sunflower oil, but is not necessarily limited thereto.

In general, the saponification process is defined as a process of preparing a soap that is a glycerin and a fatty acid salt (soap salt) by mixing a base oil and sodium hydroxide.

This process can be separated into two processes. First, the hydrolysis process of fatty acid and glycerin is produced by the reaction of base oil and water. Second, soap salt, glycerin and water are produced by the reaction of fatty acid with glycerin and sodium hydroxide. It is a neutralization process. This is summarized as follows.

Scheme 1

(RCOO) ₃ C ₃ H ₅ +3 H ₂ 0 → 3RCOOH + C ₃ H ₅ (OH) ₃

Scheme 2

3RCOOH + C ₃ H ₅ (OH) ₃ + ₃ NaOH → 3RCOONa + C ₃ H ₅ (OH) ₃ + 3 H ₂ 0

In the process of producing a solid natural soap, in particular, the neutralization process of low-temperature aged natural soap is a process in which soap salt is produced by combining fatty acid, glycerin, and water, and when it is left in a natural state, the reaction takes 4 to 6 weeks.

The saponified natural soap raw material has to undergo a low temperature aging process of 4 weeks or more, but the present invention promotes the reaction of fatty acid, glycerin, and sodium hydroxide produced through hydrolysis through a repeated kneading process to further shorten the period of neutralization aging.

An apparatus for rapidly aging a solid natural soap will be described again below.

After the preparation of the solid natural soap is completed, the solid natural soap is pelletized into small pieces, and then put into a pressure bath (step 20).

The pressure bath includes water (distilled water), and pressure-solidifies the solid natural soap for a predetermined time at a predetermined temperature and pressure in the pressure bath (step 30).

Preferably, the temperature in step 30 may range from 70 to 120 degrees, more preferably from 70 to 80 degrees.

In addition, the pressure may have a range of 1 to 1.2 atm above the atmospheric pressure.

In addition, the pressure bath time may be in the range of 60 to 84 hours, preferably 72 hours.

When the liquid natural soap is dissolved at a predetermined temperature and liquefied, glycerin contained in the solid natural soap is separated and aggregated separately.

In this case it will not function as a soap.

However, in the case of a pressure bath as in the present invention, the aggregated glycerin is decomposed by pressure, and the degraded glycerin is combined with the aqueous layer.

After the glycerin and the aqueous phase are combined, the natural liquid soap is cooled (step 40).

Step 40 is a natural cooling process and the cooling time may be carried out for 8 to 18 hours, preferably for 12 hours.

After natural cooling, the natural extract or flavor is added (step 50).

After natural cooling, the addition of natural extracts or scents is because the intrinsic ingredients and scents may evaporate if they are added at high temperatures.
