Are biological enzymes harmful to the human body?

Bioenzymes are biocatalysts that are produced or extracted from biological organisms. Catalysts are substances that have the ability to accelerate chemical reactions, and do not change themselves in chemical reactions. In layman's terms, catalysts are some special substances with catalytic effect. As a member of the catalyst family, enzymes have their special properties. Each biological enzyme will only selectively catalyze some chemical reactions. Biological enzymes are equivalent to a key to unlocking complex compounds, the importance of which lies in the fact that their unique structure or multidimensional shape matches a certain part of the group. Once the two parts are combined, the specific chemical bond in the group molecule is changed as if a lock is opened. When the reaction is over, the enzyme is released to repeat the reaction with the next group, and the sequence is repeated. Many chemical reactions are so slow at normal temperatures that the entire process is difficult to detect.

Biological enzymes have been studied by scientists for more than a century, and it is generally believed that there are more than 3,000 known enzymes. At present, biological enzymes are applied in a wide range of technologies in textiles. They have been used in fiber modification, silk degumming, raw hemp (ramie, flax, Kenaf) degumming, desizing, scouring, finishing and washing processing of dyeing and finishing, wastewater treatment of textile printing and dyeing, and garment processing of garments. Biological enzyme technology has unique advantages in improving dyeing and finishing process, saving energy consumption, reducing environmental pollution, improving product quality, increasing added value and developing products with new raw materials. At present, the widely used enzyme preparations in textile processing are mainly eight types of cellulase, protease, amylase, pectinase, lipase, peroxidase, laccase and glucose oxidase.

Recently, there has been a growing interest in the use of enzymes in cosmetics, not only from a technical point of view, but also from market prospects and consumer awareness of these ostensibly effective ingredients. Enzymes have been used in laundry detergents for over 20 years and have long been associated with properties that provide and enhance powerful stain removal. According to some speculations, their positive response in the market may be explained as performance-enhancing cosmetics that meet the needs of an aging population and pursue rejuvenation. The process of natural skin exfoliation is controlled by an enzymatic reaction, with specific enzymes lysing the desmosomes that release dead epidermal cells. These enzymes are produced in dying keratinocytes. Their active site engulfs sulfhydryl groups and clears peptide bonds in much the same way that thioglycolic acid and mercaptoalanine (plus derivatives) break peptide bonds in hair when perming. The use of these types of enzymes and their cofactors helps to cleanse the skin's surface and is an opportunity for new products to supplement the skin's appearance (speed up cell turnover).
