The integration of biological enzymes into functional cosmetics is gaining significant traction. This trend is driven by technological advancements, market potential, and increasing consumer awareness of effective raw materials.
Enzymes have been utilized in laundry detergents for over two decades, primarily for their robust stain removal capabilities. Their success in this domain has paved the way for their application in cosmetics, particularly for an aging population seeking youthful skin.
The skin's natural exfoliation process is regulated by enzymes. These enzymes break down the desmosomes, which are the structures that hold dead epidermal cells together. By dissolving these connections, enzymes facilitate the shedding of dead skin cells, promoting a smoother and more radiant complexion.
Enzymes function by lowering the activation energy required for chemical reactions, thereby accelerating these processes. When applied to the skin, enzymes increase the energy levels of substrate molecules, leading to more efficient reactions. This results in the breakdown of dead skin cells and other impurities on the skin's surface.
Coenzymes and cofactors play a crucial role in enhancing the efficacy of enzymes in cosmetics. These molecules are stable, have low molecular weight, and can penetrate the skin's keratinous layer, activating existing enzymes. Their integration into cosmetic formulations is relatively straightforward and safe.
Glutathione is a tripeptide that captures hydrogen peroxide radicals and superoxide dismutase, protecting hemoglobin in the blood from converting to methemoglobin. It releases a small amount of hydrogen sulfide gas in solution, which does not affect the stability of cosmetic formulations. Notably, the active site of glutathione superoxide dismutase contains selenocysteine, an unusual amino acid. Despite selenium's known toxicity, low levels can be safely used as a key mineral component.
Superoxide dismutase (SOD) is another critical enzyme in cosmetics. It neutralizes free radicals, reducing oxidative stress on the skin. This enzyme helps maintain the skin's youthful appearance by preventing damage from environmental factors.
Using enzymes in cosmetics offers several benefits, including:
The global market for enzyme-based cosmetics is expected to grow significantly. According to a report by Grand View Research, the global cosmetic enzymes market size was valued at USD 1.2 billion in 2020 and is projected to expand at a compound annual growth rate (CAGR) of 7.5% from 2021 to 2028 (source).
The application of biological enzymes in functional cosmetics holds immense potential. These enzymes offer numerous benefits, from anti-aging effects to enhanced skin health. As research continues to explore their safety, stability, and efficacy, enzyme-based cosmetics are poised to make a significant impact on the quality of life for consumers worldwide.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
