Soap, facial wash, body soap, and shaving foam including sericite formulated therein, and production method of soap, etc

Abstract

To develop a soap, a body soap, and a shaving foam which lather well and cause a mild finish of washing while removing pore dirt, an old cuticle, and excess sebum on skin and where the shaving foam, when used in shaving, has an effect of preventing a razor burn due to rubbing.SOLUTION: A soap of the present invention is a mixture of a soap composition with sericite mixed thereinto. Examples of the soap can include a solid soap, a facial wash, a body soap, and a shaving foam. In production of soap liquid, sericite (another name: mica sericite) is formulated in the amount of, desirably, 0.6 to 0.7% by weight based on a weight of an oil and fat in the soap composition and then the resultant is matured for a predetermined period to produce the soap.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a soap that, by blending powdered sericite (also known as mica or silk mica), an ingredient that is mainly used as a main ingredient in cosmetic foundations, produces good lather, removes dirt from pores, dead skin cells, and excess sebum from the skin, while leaving a mild feeling after washing, and prevents razor burn caused by friction when used during shaving. [Background technology]

[0002] There are clay soaps and scrub soaps that are designed to lather soap and remove dirt from pores. These are effective for oily skin and for partially washing the face, but when used by people with normal or sensitive skin, they have the disadvantage that they absorb more oil than necessary from the skin, leaving the skin feeling tight after washing and causing irritation from the scrub. In addition, many people shave at the same time as washing their face, but regular soaps do not sufficiently reduce friction, and razor burn may occur. Summary of the Invention [Problem to be solved by the invention]

[0003] To develop a soap which removes the above-mentioned dirt from skin pores while leaving necessary oils behind, places less strain on the skin, and is effective in preventing razor burn. [Means for solving the problem]

[0004] In light of this situation, the inventor tried many ingredients that would remove dirt from fine pores, dead skin cells, and excess sebum while minimizing irritation to the skin and leaving the skin feeling smooth after washing. As a result, he discovered that a soap containing an appropriate amount of sericite (also known as mica or sericite) would provide these effects, and thus completed the invention. (1) A soap, face wash, body soap, and shaving foam, characterized in that the weight of sericite (also known as mica or sericite) is preferably 0.6 to 0.7% based on the weight of fats and oils that are one of the soap compositions. (2) When making soap solution using caustic soda, sericite (also known as mica) is weighed into a bowl before measuring out the fats and oils, and then mixed with the specified amount of fats and oils, so that the fine particles are mixed evenly into the ingredients, and a more consistent effect can be expected. In detail, because soap solution is strongly alkaline, when mixing ingredients that are weak to alkali, they are mixed at the end of the manufacturing process to avoid deterioration of the ingredients, but sericite is not altered by alkali, so by mixing it in from the beginning of the manufacturing process, soap solution with powder evenly distributed can be produced. Effect of the Invention

[0005] According to the present invention, it is possible to provide a soap that lathers well, removes dirt from pores, dead skin cells, and excess sebum from the skin, leaves a mild feeling after washing, and has the effect of preventing razor burn caused by friction when used during shaving. (1) The sericite used is fine, with an average particle size of around 10 μm, so it puts less strain on the skin and removes dirt from fine pores, keeping the skin clean. (2) The sericite particles adhere to soap bubbles, creating a light, fluffy foam and helping it to last longer. This allows the foam to be used to gently cleanse the skin without putting a strain on the skin. (3) Compared to clay, sericite does not absorb excess sebum, so it is less likely to leave your skin feeling tight after washing. (4) Sericite was once used as a cushioning material in textile factories to prevent threads from breaking due to friction with machines. Just as sericite was once used as a cushioning material between the razor and the skin, it can be expected to prevent razor burn. (5) In particular, sericite produced in Toei Town, Kitashitara County, Aichi Prefecture, is of higher purity and has finer particles than sericite produced overseas, so it is less harsh on the skin. [Brief description of the drawings]

[0006] [Figure 1] FIG. 2 is a diagram of an example of a method for producing a bar soap containing sericite. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] (1) Sericite, an essential component of the soap of the present invention The soap of the present invention is characterized by containing sericite (also known as mica or sericite) at a weight of preferably 0.6% to 0.7% based on the weight of the fats and oils that are one of the soap compositions. If the soap contains more sericite than this, it may cause a burden on the skin due to friction, and if the content is less than this, sufficient effects cannot be expected.

[0008] (2) The soap of the present invention is preferably produced using the neutralization method (cold process method) with a water content of 25-35% relative to the weight of the fats and oils, and a saponification rate of 85-92%. When making soap solution using caustic soda, it is recommended to measure sericite (also known as mica) into a bowl before measuring the fats and oils, and then mix it with a specified amount of fats and oils. This will allow the fine particles to be mixed evenly into the ingredients, which is expected to produce a more consistent effect. EXAMPLES

[0009] The present invention will be described in further detail below with reference to examples, but it goes without saying that the present invention is not limited to these examples. Fig. 1 is a process diagram of a method for producing a solid sericite-containing soap containing the above-mentioned sericite. This soap is obtained by mixing sericite with a soap composition, and examples of the soap include solid soap, face wash, body soap, and shaving foam. In this embodiment, solid soap is described in detail as an example, but the present invention is not limited to solid soap, and can of course also be applied to other types of soap such as liquid soap, powder soap, gel soap, and cream soap. EXAMPLES

[0010] According to the recipe shown below, soap containing sericite of the present invention was produced following the process shown in FIG. (a) 250g olive oil (b) Palm kernel oil 150g (c) Palm oil 100g (ii) Sericite 3g (e) Caustic soda (sodium hydroxide) 65.7g (f) 150g purified water

[0011] Next, an embodiment of the soap manufacturing method according to the present invention will be described. Fig. 1 shows a flow chart of the soap manufacturing method according to the present invention, and the steps will be described in order according to this figure. (1) Measure the sericite (ii) into a bowl.

[0012] (2) Measure out the oils (fats) listed above (A) through (C) into the bowl containing the sericite and heat in a hot water bath.

[0013] (3) Measure out the caustic soda (e) and purified water (f) into separate containers.

[0014] (4) Add the entire amount of caustic soda (e) to the container of purified water measured in (3) and dissolve it, then allow to cool.

[0015] (5) When the oil (2) and the caustic soda water (4) have reached approximately 40-45°C, gradually add the caustic soda water to the bowl containing the oil, and mix using a whisk or similar device until the soap solution in the bowl becomes like custard cream.

[0016] (6) Once the soap mixture has turned into a custard-like consistency, pour it into a mold and keep it warm for 24 hours.

[0017] (7)(6) After a few days of pouring into the mold, the mixture is removed from the mold and allowed to further mature (saponify).

[0018] (8) After about two weeks from removing from the mold, cut into appropriate sizes and allow to further mature (saponify).

[0019] (9) Once removed from the mold, the mixture is left to mature (saponify) for at least one month before it is ready. [Industrial Applicability]

[0020] The present invention can be applied to face washes, body soaps, and shaving foams that are environmentally friendly, have excellent cleaning properties, and are gentle on the skin.
