Description

FIELD OF THE INVENTION [0001] The present invention relates to a natural soap and a method for producing the natural soap,

The present invention relates to a weakly acidic natural soap and a method for producing the same. More particularly, the present invention relates to a weakly acidic natural soap having no skin irritation using an Aronia juice extract and an Aronia liquorice extract, and a process for producing the same.

There are various kinds of soaps that are used to remove skin wastes and sebum components when they are attached to human skin to maintain the cleanness of the skin. Generally, soaps used for human body washing use alkaline salts of higher fatty acids So as to saponify the oil.

Therefore, the kind of the oil that is the raw material of the soap is limited to various conditions, and the characteristics of the product vary according to the specific properties of the oils used in the soap. Therefore, various kinds of additives may be combined It should have appropriate efficacy and effectiveness. Accordingly, the development trend of soap has recently been promoted in the direction of developing something having a specific function.

However, most commercially available soaps use surfactants synthesized in petroleum systems. Surfactants are a generic term for materials that impart an activity between water and oil, skin and waste products, which can cause water and oil to blend into one another or to easily remove wastes from the skin. Surfactants that adsorb on the interface to make bubbles well and leave time will remain on the surface and pores of the skin, excessively removing sebum and moisturizing factors that help skin health, making the skin dry and promoting skin aging And it can be combined with other chemicals to synthesize nitrosamine, a carcinogen, and seriously affect the human body. Surfactants have the risk of causing cell destruction and various diseases.

Acne, on the other hand, is a chronic disease of the epidermis that occurs mainly on the face, chest, and neck of young men and women, such as puberty, and forms comedones, papules, pustules, cysts, or nodules , A severe lesion that can leave a scar. If the skin is damaged by acne, it can cause mental harm such as depression and interpersonal avoidance.

The cause of acne has not yet been clarified, but excluding genetic and environmental factors, acne has been recognized to be caused by the following three factors.

The first cause is abnormal sebum secretion. Excess sebum secretion is closely related to testosterone, a testosterone that is converted to dihydrotestosterone (DHT) by 5 alpha-reductase in skin cells to enhance the activity of sebaceous glands (Rosenfield RL and Deplewski D. Role of androgen in the developmental biology of the pilosebaceous unit. The American Journal of Medicine 1995; 16: 80s-88s).

The second cause is that the pores are closed due to hyperkeratinization of the hair follicles. The resulting sebum must be smoothly drained out of the skin. However, due to the overgrowth of the hair follicles, the pores are clogged and smooth release of sebum is suppressed, resulting in stagnation of the sebaceous follicles in the hair follicles and formation of fine sebaceous glands. This is the early stage of acne.

The third cause is the promotion of the growth of Propionibacterium acnes , a resident acne germ in the hair follicle, which leads to worsening of acne lesions. As the acne bacterium grows in the sebaceous glands, triglyceride constituting sebum is converted into free fatty acid and acts as irritants or as a comedogenic substance to produce acne. (Sergio Nacht, Cosmetics Toiletries, 101, 47-55, 1986; Wei-Li Lee et al., Infection and Immunity, 35, 71-78, 1982).

In other words, the acne bacterium that resides in the hair follicle forms a pore wall irritant material, and the fine cotton bacillus is gradually increased in size due to the excess secretion of sebum, so that the hair follicle wall becomes thinner and the irritant material produced by the acne bacterium Stimulates the thinned hair follicle wall, and the mucosa gradually worsens and progresses to papules, pustules, nodules and scars.

Therefore, evaluation methods for current acne treatment and mitigation effects are based on the above-mentioned action mechanisms, and methods for evaluating sebum secretion control, suppression of extinction, antimicrobial activity against acne bacteria, and mitigation effects of acne have been used (Madli Puhvel, Kathy Perisho et al., J. of Invest. Dermatol, 90, 350-353, 1988; Hyeyoung Kim et al., Korean J. Ginseng Sci., 14, 391-398, 1990; RA Bojar et al., British J. of Dermatology, 132, 204-208, 1995; AM Kligman et al., British J. of Dermatology, 100, 699-702, 1979).

As a method commonly used to treat acne using drugs, salicylic acid or a vitamin A derivative retinoic acid is used to suppress the formation of pores and keratin, Or by using benzoyl peroxide, triclosan, sulfur or tea tree oil preparations to remove the dead skin cells and prevent acne through antibacterial action. A method of mitigation is being used. However, the salicylic acid preparation has a small therapeutic effect, and may cause skin redness, edema or skin ghrefaction. The retinoic acid agent has an effect through suppression of hyperalgesia, but contact dermatitis, erythema, skin drying and exfoliation . In addition, benzoyl peroxide and trichlonic acid preparations have side effects such as allergic contact dermatitis, scarring, and severe erythema. On the other hand, azelaic acid, which has been recently introduced, has a reduced drug side effect, but has a lower therapeutic effect than conventional therapeutic products.

Therefore, it is urgent to develop hypoallergenic natural soap which can alleviate various skin troubles including acne without using a synthetic surfactant.
