Description

SKIN CLEANSING PRODUCT

Subject of the Invention

The subject of the invention relates to a skin cleansing product with natural ingredients.

State of the Art

In order to achieve the hand hygiene, the hands are frequently washed with soap, or the products with high alcohol content such as disinfectants and colognes are used for this purpose. However, the dryness, irritation eczema and sensitivity develop on the skin upon an increase in the duration and frequency of hand washing and upon excessive disinfectant or cologne use. The need for the development of the novel products with natural ingredients has increased in order to prevent these problems encountered in the skin and support the skin renewal with the products used during the washing.

From time to time, the changes occur in our cleaning habits and the importance attached to the personal hygiene increases with the development of conditions adversely affecting our health such as epidemics. The hand hygiene is also critical for providing the personal hygiene. Washing the hands frequently or disinfecting the hands with the products with high alcohol content lead to bigger problems for the individuals with sensitive or dry skin. Excessive skin exposure to the cleansing agents further causes the disruption of the barrier/protective feature of the skin.

Consequently, the products, which include natural ingredients in addition to providing an effective cleansing property, have started to be preferred for achieving the skin cleansing. Today, many products that come into contact with the skin do not have natural ingredients. The products contain various chemicals. This leads to the side effects causing damage to the skin health.

According to the state of the art, it is aimed to protect the skin's moisture barrier by the use of the products with skin moisturizing action after the cleansing of the skin. However, this necessitates the use of a separate moisturizing product at all times. While the users try to minimize the damage to the skin by using the separate products with a view to minimize the effects of the products with chemical ingredients on the skin, they turn towards the use of the natural products or the products with natural ingredients. It is the priority target to reduce the effects of the chemical substances by preferring the products with natural ingredients for preserving our skin health. The conscious consumers make their choice of the products to use by considering the natural raw material ratios of the products in addition to their price.

Within the scope of the invention, a skin cleansing product, which helps reduce the spread of the bacteria received from the ambience via contact, is suitable for the sensitivity of the skin, has the moisturizing action, and, upon the long-term use, helps reduce the skin spots, promotes the tissue renewal and supports the reduction of the fine lines and wrinkles, has been developed.

Object of the Invention

An object of the invention is to develop a skin cleansing product with natural ingredients.

An object of the invention is to develop a skin cleansing product, which is suitable for the sensitivity of the skin, has the moisturizing action, and, upon the long-term use, helps reduce the skin spots, promotes the tissue renewal and supports the reduction of the fine lines and wrinkles.

Another object of the invention is to develop a hand washing product.

Detailed Description of the Invention

The product developed within the scope of the invention comprises at least one type of vitamin important for the health of the skin, at least one agent conferring antioxidant and antibacterial property, and at least one moisturizing agent. The product developed within the scope of the invention comprises the vitamin at a ratio of 1-3% by weight, the agent conferring antioxidant and antibacterial property at a ratio of 1-1.5% by weight and the moisturizing agent at a ratio of 0.5-1.5% by weight.

The product developed within the scope of the invention preferably comprises the ingredient nicotinamide as the vitamin. There are many studies available demonstrating the positive effect of the substance nicotinamide (vitamin B3) on the skin health. Nicotinamide assists with the generation of protein in the skin and with the entrapment of moisture in order to prevent the environmental damage. It is used as an auxiliary means for the treatment of certain skin problems, notably acne and eczema. By the use of the ingredient nicotinamide in the product developed within the scope of the invention, the skin will be assisted in forming a ceramide (lipid) barrier that would in turn preserve the moisture. The contribution will be provided to the prevention of especially the dry skin and eczema resulting from washing the hands with excessive soap and from the use of disinfectants. Other known features of the substance nicotinamide include its ability to remove the redness and spots and to reconstruct the healthy skin cells while at the same time protecting the same from the damages caused by the ultraviolet rays. Providing a spot-reducing action and minimizing the fine lines and wrinkles in the long term are the other features intended to be provided by the use of a nicotinamide-containing product in the skin types that are aging and that have reduced tissue renewal. The studies show that the substance nicotinamide further assists with the reduction of some signs of solar damage that develop upon aging. This includes the fine lines and the wrinkles.

The use of propolis is preferred as the agent conferring antioxidant and antibacterial property. Since propolis is able to effectively inhibit the production of lipid peroxides, it has a broad-spectrum antibacterial and sterilizing action. It has good antioxidant action and is known as an antioxidant and a free radical scavenger. There are studies suggesting its ability to exhibit good inhibitory action on the bacteria, fungi and virus. By the use of the raw material propolis, it is possible to act on the skin metabolism and preserve the skin health upon the skin absorption of numerous nutrients it contains (vitamins Bl, B2 and B6, folic acid, pantothenic acid, inositol, niacin, vitamin H, linoleic acid, linolenic acid, various amino acids, trace elements, etc.). The natural pharmaceutical components of terpene contained in propolis have more prominent antibacterial, itch-relief and anti-inflammatory actions. The product developed within the scope of the invention will exhibit antioxidant and antibacterial action, as a result of comprising propolis. Propolis is a propolis ethanol extract.

Within the scope of the invention, the use of hyaluronic acid is preferred as the moisturizing agent. Hyaluronic acid serves to increase the absorption of the product in which it is present. In the product according to the invention, it is planned to achieve greater action of the ingredient nicotinamide by the addition of hyaluronic acid. Owing to the combined use of the ingredients hyaluronic acid and nicotinamide, it will be possible following the use of the product for a time to achieve whitening in the skin, retain moisture and prevent the loss of retained moisture, preserve the elasticity of the skin surface, improve the radiance of the skin and delay the aging of the skin, as well as accelerating the skin metabolism, enabling the color spots to fade up to the point of disappearance and achieving the function of ultraviolet ray prevention.
