Description

Technical Field

[0001] A cosmetic composition for improving body skin condition containing Makgeolli lees and beer lees and a method for producing the same. Background Art

[0002] The skin protects the body's organs from external stimuli such as temperature and humidity changes, UV rays, and pollutants, and acts as a barrier to prevent the evaporation of water within the skin.

[0003] Skin ages gradually. Internal factors of skin aging include genetic mutations and tissue changes, and external factors include the effects of ultraviolet rays and humidity. As you age, dry skin or weakened immunity may cause itching. This itch robs you of the serenity of daily life, especially if you are an elderly person living alone, and it can be a depressive turn, just like not having someone to scratch your back.

[0004] At the same time, recent awareness of the harmful effects of synthetic chemicals and increased interest in sustainability and ethical consumption are increasing demand for the product.

[0005] TechCi Research is an international market research company headquartered in Burnaby, British Columbia, Canada. TechSci Research - The global organic cosmetics market is growing due to the growing demand for chemical-free personal care products and the changing lifestyles of consumers associated with organic care. The growth is expected to continue, and the eco-friendly (organic) body products market will increase from $9.83 billion in 2021 and $10.49 billion in 2022 to $21.16 billion in 2030 during the forecast period 2023-2030. The CAGR is expected to be 8.9%.

[0006] Wine lees refers to the residue left after filtering alcohol, adding water, and squeezing out the mother liquor. Wine lees, alcohol, runners, residence, it is also called alcoholic beverage.

[0007] Sake is usually disposed of, which may cause environmental pollution and disputes between local residents due to land reclamation, etc. However, since sake lees contain ingredients that are useful to the human body, it is necessary to give these waste resources different values ​​(Re-value).

[0008] There have been various attempts to utilize distiller's grains in the past, but there are limitations in the extraction of useful components for extracts prepared from distiller's grains, and for this reason it remains difficult to find products developed using distiller's grains as the main raw material.

[0009] Therefore, by recycling the waste resource of sake lees, we can provide environmentally friendly and affordable products and reduce production costs. Creative reuse (upcycling) is very important for effectively extracting various components contained in sake lees and transforming them into new high-value-added products rich in ingredients useful to the human body.
