It is a structural analogue of I±-MSH. By competitively binding the melanin stimulating hormone receptor MC1-R on melanocytes, the melanocytes cannot produce tyrosinase, thereby inhibiting the activity of melanocytes and reducing the production of melanin. According to some clinical trials, undecylenoyl phenylalanine can indeed reduce spots caused by pigmentation. According to research, this ingredient can block �±-MSH at a concentration of 0.001%, if the concentration is 1%. Then, the melanin production can be fully suppressed from multiple links, and the effect is more obvious and lasting. Undecylenoyl phenylalanine has the following characteristics: 1. Significant skin biocompatibility (lipid amino acid structure) 2. Innovative mode of action �±-MSH antagonist 3. Compared with whitening agents such as arbutin, kojic acid, and vitamin C phosphate magnesium, the effect is more significant. 4. Human experiments have proved that its whitening and lightening effect is remarkable. 5. Highly safe within the recommended dosage (2%). 6. Easy to formulate (very easy to use). 7. Has good compatibility and excellent stability

1. Chopped basalt fiber Basalt fiber is a kind of inorganic fiber material. Chopped basalt fiber is an inorganic mineral fiber with a length of less than 50mm and can be evenly dispersed in cement concrete. 2. Characteristics of chopped basalt fibers (1) The naturalness of raw materials. Because the raw material for producing continuous basalt fiber depends on the natural volcanic extrusive rock, there are no ingredients harmful to human health except that it is inherently high in chemical stability and thermal stability. (2) Comprehensive performance. Basalt fiber is acid resistant and alkali resistant. It is both low temperature and high temperature resistant. It is insulated and insulated by heat and electricity. Its tensile strength is higher than that of large tow carbon fiber. Its elongation at break is even better than that of small tow carbon fibers. It has high compressive strength, shear strength and adaptability to aging, and has good comprehensive properties in harsh environment. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of steel fiber and polyester fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with asphalt concrete, cement concrete and mortar. The newly mixed basalt fiber concrete has stable volume, good workability and durability, and has superior high temperature resistance, anti-seepage, crack resistance and impact resistance.

1. Basalt short fiber - a new material to replace steel fiber. Basalt short fiber is an inorganic mineral fiber with a length of less than 50mm, which can be evenly dispersed in cement concrete. 2. Characteristics of basalt short fiber (1) the specific gravity of steel fiber is 7.8 and that of cement concrete is 2.5. After mixing, the specific gravity of steel fiber is higher than that of cement, and the cement will sink and have poor dispersion. The specific gravity of basalt short fiber is 2.6, which is basically equivalent to that of cement concrete. After mixing, it does not sink, has good dispersion, is degradable, and is green. The road surface will not be as hard as steel fiber, resulting in car driving noise.. (2) Basalt staple fiber is a real "multifunctional" fiber. Acid and alkali resistance (especially alkali resistance, fully applicable to cement concrete), low and high temperature resistance, insulation and sound insulation. The tensile strength is three times that of steel fiber. The corrosion resistance of basalt fiber is better than that of steel fiber. The compressive strength is 20% higher than that of steel fiber, which is suitable for harsh environment. It has excellent comprehensive performance. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of 50% steel fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with cement concrete and mortar. Fresh basalt fiber concrete has stable volume, good workability and durability, and has excellent high temperature resistance, impermeability, crack resistance and impact resistance.
