Pure Hydroquinone Powder

What is Hydroquinone?

Pure Hydroquinone Powder, also known as hydroquinone, is an important organic compound. It is a dihydroxy-substituted derivative of benzene in molecular structure, with two para-hydroxyl groups, which makes it have strong reducing properties. It is one of the isomers of hydroquinone. As a phenolic compound and decolorizing agent, it is one of the most widely used whitening ingredients. Its mechanism of action is to inhibit the production of melanin, which can effectively treat pigmentation, dark spots and chloasma. It has active chemical properties and is easily oxidized. It can also undergo esterification and substitution reactions. It is widely used in medicine, cosmetics and other fields.

Product Details List

Properties

1. White needle-shaped crystals, flammable, soluble in hot water, ether and ethanol, slightly soluble in benzene. It has reducing properties, and mild oxidation gives brown p-benzoquinone, which is reduced to hydroquinone. The p-benzoquinone-hydroquinone redox couple exists in many biological molecules, such as coenzyme Q.
2. It has weak acidity and can lose one or two protons to generate corresponding phenolate anions. It is mainly used as a reducing agent, developer, inhibitor of monomers, and skin whitening agent. Hydroquinone ether is a raw material in the production of dyes and fragrances.

Functions of Hydroquinone

Antifungal: It has significant antifungal effects, can inhibit the synthesis of fungal cell membranes, has antibacterial effects on dermatophytes, Candida, etc., and also has a certain inhibitory effect on certain bacteria and viruses.

Astringent: Pure Hydroquinone Powder can cause astringency of the skin and mucous membranes, which helps to treat diseases such as eczema, prickly heat, urticaria, and can also be used to treat tinea capitis and tinea versicolor.

Keratin dissolving: It can dissolve keratinized epidermal cells, which helps to treat skin diseases with excessive keratinization, such as seborrheic dermatitis, pityriasis rubra, etc., and can also be used to treat psoriasis, ichthyosis, etc.

Antipruritic: It has an antipruritic effect and can be used to treat mosquito bites, skin pruritus, etc., and can also be used to treat contact dermatitis, etc.

Antioxidant: It has the ability to scavenge free radicals, can prevent lipid peroxidation, and thus play an antioxidant role.

Inhibit melanin synthesis: Hydroquinone can reversibly inhibit the activity of tyrosinase, prevent the conversion of tyrosine into dopa, and thus reduce the production of melanin.

Whitening Mechanism

1. Destroy melanocytes: It can also destroy melanocytes and reduce the production of melanin. This effect not only reduces known melanin, but may also reduce the production of new melanocytes.
2. Inhibit DNA and RNA synthesis: By inhibiting the DNA and RNA synthesis of melanocytes, the function and number of melanocytes are further reduced.
3. Inhibit tyrosinase activity: It can inhibit the activity of tyrosinase, which is a key enzyme in the synthesis of melanin. By inhibiting tyrosinase, the production of melanin can be reduced, thereby achieving the effect of whitening the skin.

Production Method

1. Aniline is oxidized to p-benzoquinone by manganese dioxide in a sulfuric acid medium, and then reduced to hydroquinone by iron powder. The finished product is obtained after concentration, decolorization, crystallization and drying. The content of industrial-grade hydroquinone is ≥99%, and the content of photographic grade is ≥99.5%. Raw material consumption quota: aniline 1250kg/t, sulfuric acid (93%) 5500kg/tChemicalbook, pyrolusite powder (containing 60-65% manganese dioxide) 5950kg/t, iron powder (containing Fe ≥90%) 540kg/t.
2. Take nitrobenzene as raw material, and obtain it by hydrogenation and heating.
3. Take phenol as raw material, and obtain catechol and hydroquinone by oxidation with hydrogen peroxide, and separate them to obtain catechol and hydroquinone respectively.

Applications

Cosmetics and Personal Care

In cosmetics, it can be used as a hair dye and also in skin whitening products, but attention should be paid to its potential skin irritation and safety issues.

Medical Field

It has antibacterial and antioxidant properties and can be used in drug preparation, but its use as a drug ingredient must be strictly in accordance with doctor's advice.
