The product we are introducing here is N-Acetyl-L-Cysteine (NAC), with the CAS number 616 - 91 - 1. It is a derivative of the amino acid L-cysteine. NAC appears as a white to almost white crystalline powder with a characteristic odor. It is freely soluble in water and slightly soluble in ethanol. Chemically, NAC contains an acetyl group attached to the amino group of L-cysteine, which enhances its stability and bioavailability compared to L-cysteine itself.
This product is factory - supplied, which means it can be provided in large quantities at a best price, meeting the various needs of different customers from small - scale laboratory research to large - scale industrial applications.
1. **Medical Field**: NAC has long been used as a mucolytic agent. It can break down the disulfide bonds in mucus, making it less viscous and easier to cough up. This property is very useful in treating respiratory diseases such as chronic obstructive pulmonary disease (COPD), bronchitis, and cystic fibrosis. In addition, NAC is an antioxidant. It can replenish glutathione levels in the body, which is crucial for protecting cells from oxidative stress and damage. It also has potential applications in the treatment of acetaminophen overdose by providing a source of sulfhydryl groups that can conjugate with the toxic metabolites of acetaminophen.
2. **Cosmetics Industry**: NAC can be added to skin - care products. Its antioxidant properties help to protect the skin from free - radical damage, reduce the appearance of wrinkles, and improve skin texture. It can also promote collagen synthesis, which is beneficial for maintaining skin elasticity.
3. **Food Industry**: It can be used as a food additive. For example, it can prevent the oxidation of food ingredients, extend the shelf - life of products, and maintain the color and flavor of food.
1. **Medical Use**: For respiratory diseases, NAC is often administered via inhalation. The dosage usually depends on the severity of the condition and the patient's age and body weight. In general, for adults, the inhalation dosage may range from 200mg to 600mg per day, divided into several administrations. When used for acetaminophen overdose, it is usually given orally or intravenously under the strict supervision of medical professionals. The initial oral dose may be 140mg/kg, followed by several maintenance doses of 70mg/kg every 4 hours.
2. **Cosmetics**: When used in cosmetics, NAC is usually formulated into creams, lotions, or serums. The concentration of NAC in these products can vary from 1% to 5%. It is recommended to apply the product to clean and dry skin, gently massage it until fully absorbed, and use it regularly as part of the daily skin - care routine.
3. **Food Industry**: In food processing, the dosage of NAC should comply with relevant food safety regulations. It can be directly added to food products during the manufacturing process, and the specific amount depends on the type of food and the desired effect.
1. **Medical Case**: A patient with chronic bronchitis had a persistent cough and difficulty in expectorating mucus. After inhaling a NAC solution at a dosage of 300mg twice a day for two weeks, the patient reported a significant reduction in cough frequency and an easier expectoration. The sputum became less thick, and the patient's breathing also improved. After another two - week treatment, the patient's overall respiratory symptoms were greatly alleviated.
2. **Cosmetics Case**: A woman in her forties with visible fine lines and dull skin started using a skin - care serum containing 3% NAC. After using the serum regularly for three months, she noticed that her skin became more hydrated, the fine lines around her eyes and mouth were less obvious, and her skin tone became more even and radiant.
3. **Food Industry Case**: A food manufacturer added NAC to its fruit juice products. The addition of NAC at a concentration of 0.1% effectively prevented the oxidation of the juice, maintaining its original color and flavor for a longer time during storage. This led to a significant reduction in product spoilage and an increase in customer satisfaction.
