Paraformaldehyde is a polymer of formaldehyde with the chemical formula (CH2O)n, where n is typically in the range of 8 to 100. It is a white, crystalline solid composed of small, polymeric formaldehyde units. Paraformaldehyde is commonly used as a solid form of formaldehyde, and it has various applications in different fields. Form and Structure: Paraformaldehyde is a low-molecular-weight polymer of formaldehyde, consisting of repeating CH2O units. It is often produced in the form of white, crystalline granules or as a powder. Uses: Fixative in Histology: Paraformaldehyde is commonly used in histology and pathology laboratories as a fixative for preserving biological specimens for microscopic analysis. Disinfectant: It has disinfectant properties and can be used for sterilizing equipment. Crosslinking Agent: Paraformaldehyde is used in the crosslinking of proteins, peptides, and nucleic acids in molecular biology applications. Chemical Synthesis: It serves as a source of formaldehyde in various chemical reactions and syntheses.

Even if the concentration of ferulic acid solution is only 0.5mmol/L,its inhibition rate of tyrosinase activity can reach about 35%.Ferulic acid also has the ability to scavenge oxygen free radicals and good anti-oxidation.Ferulic acid has sun protection ability.Ferulic acid can effectively absorb ultraviolet rays in the wavelength range of 290-330nm to prevent or reduce the damage of this wavelength of ultraviolet rays to the skin. Main Function: 1. Ferulic acid can protect skin against sun The chemical black name of ferulic acid is 4-hydroxy 3-methoxycinnamic acid. Among them, the commonly used sunscreen is "Ethylhexyl Methoxycinnamate (OMC)". Therefore, both of the cinnamic acid family, ferulic acid also has the effect of absorbing ultraviolet rays and sunscreen. It is also recognized as one of the sunscreens in Japan. 2. Ferulic acid can resist oxidation Ultraviolet rays will create a variety of free radicals with electrons on our skin, which will cause a series of cell damage and make the skin age down.This is photo-aging.Compared with general sunscreens, ferulic acid can also resist oxidation and eliminate free radicals. 3. Ferulic acid can be anti-inflammatory On the one hand, ferulic acid can cut off the key link in the inhibition of inflammation, such as affecting the metabolism of arachidonic acid, inhibiting the synthesis of prostaglandin PEG2, and can also calm the immune system and reduce the activation of mast cells, which can play an anti-inflammatory and anti-allergic effect. 4. Ferulic acid can whitening skin Tyrosinase is the most critical enzyme needed by melanocytes to produce melanin.Ferulic acid can inhibit the production and activity of tyrosinase,so as to achieve the whitening effect of reducing the production of melanin.
HiraChem is your specialist supplier of Sodium Hydroxide. Sodium Hydroxide (Caustic Soda ) 98-99% Flakes. Sodium Hydroxide, also known as lye and caustic soda, is an inorganic compound with formula NaOH. It is a white solid, a salt (ionic compound), consisting of sodium cations Na+ and hydroxide anions OHâ??. Sodium hydroxide is a highly caustic base and alkali, that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates NaOH·nH2O. The monohydrate NaOH·H2O cystallizes from water solutions between 12.3 and 61.8 C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound
