What Are the Precautions for Using Resorcinol?

Resorcinol is a water-soluble colorless crystal at room temperature, flammable, sweet, easily soluble in water, alcohol and ether, insoluble in chloroform, carbon tetrachloride and benzene, with a weak special smell. Resorcinol is weakly acidic, but stronger than carbonic acid. Our resorcinol china is easy to gradually turn light red when exposed to sunlight and air for a long time.

1. The shape of resorcinol

Resorcinol is a white or off-white needle crystal or powder; it has a slight odor; it slowly turns pink in sunlight or in the air. Resorcinol is easily soluble in water or ethanol, easily soluble in ether or glycerol, and slightly soluble in chloroform.

2. Pharmacological effects of resorcinol

Resorcinol 0.25% to 1% is a keratinogenic agent, 5% is a keratin loosening agent, 20% to 40% is an exfoliating agent, and more than 40% is a corrosive agent. Resorcinol products have the effect of killing bacteria and fungi, and the effect is 1/3 of that of phenol. It also has antipruritic effects and is less irritating to the skin. Soluble in water, alcohol and other solvents. It has the effect of inhibiting bacteria and fungi. Effects of different concentrations on the skin. Low concentration (0.5%-1%) can relieve itching and promote keratin formation, 5% concentration can release keratin, high concentration (20%-40%) has keratin exfoliation effect, and concentration above 40% has corrosive effect.

3. Adverse reactions to the use of resorcinol

Can cause contact dermatitis. Because resorcinol can be absorbed through the skin or ulcers, it should not be used in high concentrations and large areas in infants and young children; poisoning symptoms include diarrhea, nausea, vomiting, stomach pain, dizziness, severe or persistent headache, fatigue or weakness, irritability Or irritability, drowsiness, night sweats, bradycardia, shortness of breath; children apply resorcinol to the wound can cause methemoglobinemia. Avoid contact with eyes. Resorcinol can darken light-colored hair, and can cause redness and scaling within days of use. Resorcinol, suggested by the professional chemical material supplier, when combined with soaps, cleansers, acne preparations, alcohol-containing preparations, or retinoids, can cause excessive irritation or dryness of the skin.

4. Precautions for resorcinol

Individual patients may experience local redness, tingling, dry skin, etc. after applying the medicine, which usually subsides within 1-2 minutes. Add vitamin C to the resorcinol solution to prevent oxidative discoloration. Resorcinol is less irritating and can be absorbed through wounds and damaged skin, causing myxedema. This crystal is prohibited from co-grinding with ethyl nitrite, iron salts, interactive resorcinol products, antipyrine, camphor, chloral hydrate, menthol, phenol: pyrogallol, etc., and it will liquefy or soften. This crystal forms colored compounds when it encounters chloral hydrate, ramie lycete, etc. Silver, mercury and copper salts can be reduced by resorcinol.
