Description

Solid carbonated bath additive composition containing melatonin and method for manufacturing same {SOLID CARBONATED BATH COMPOSITION CONTAINING MELATONIN AND METHOD FOR PREPARING THE SAME}

The present disclosure relates to a solid carbonated bath agent composition containing melatonin and a method for producing the same.

Melatonin is a type of hormone produced in the brain and is a drug commonly used to treat insomnia. It is mainly used in the form of ingestion, and these days, cosmetic products are being released frequently.

Unlike when taken, melatonin as a cosmetic raw material is not classified as a prescription drug and can be used as a general cosmetic raw material. When applied to the skin, the main effects include 1) recovery and improvement of skin tone, 2) anti-aging, and 3) reversal of signs of skin aging. It helps improve the body's sleep and wake cycle and is comparable to vitamin C and vitamin E. It is known to have antioxidant properties. In addition, human skin and hair follicles express functional melatonin, which is known to significantly contribute to melatonin synthesis. Through this, melatonin not only acts in the epidermal layer as a cosmetic raw material, but is also absorbed into the body through the skin. It can be seen that similar effects as when taken can be achieved supplementally.

Bathing by soaking in a bath is being studied in many aspects, including promoting blood circulation, improving the respiratory circulatory system, increasing immunity, suppressing appetite, and improving obesity due to increased metabolism. Bathing is also known to have a positive effect on suppressing stress hormones. In this way, bathing is not simply a cosmetic effect that aims to neaten the epidermal layer of the skin, but is also an act that produces positive effects by influencing the body's internal organs (autonomic nervous system and sympathetic nervous system). Bathing can also help you sleep better by relaxing your muscles and helping relieve fatigue. This type of deep sleep has a significant impact on the production of melatonin within the body and can be seen to have an effect on body metabolism beyond its effect on the epidermis.

The effects of bathing, such as half-body bathing where you soak in a bath for a long time, can affect the skin's epidermis/stratum keratin in addition to the internal effects. Skin generally has a turnover cycle of 28 days. The turnover cycle is when new cells in the skin layer grow and old cells are gradually pushed up into the stratum corneum and then fall off. The act of bathing can physically and intentionally induce this cycle, leading to the exfoliation of the stratum corneum. The stratum corneum that has been softened by bathing for 20-30 minutes can be intentionally exfoliated to a certain level through scrubbing or surfactants. If the active ingredient is applied to the stratum corneum that has become thinner through these actions, the absorption rate is higher than the absorption rate of raw materials applied in daily life. The active ingredients can be absorbed.
