1. What is Fullerene？

A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms. The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes.

The family is named after buckminsterfullerene (C60), the most famous member, which in turn is named after Buckminster Fuller. The closed fullerenes, especially C60, are also informally called buckyballs for their resemblance to the standard ball of association football ("soccer").

2. Why does fullerenes used in cosmetics？

Fullerene is a long-acting antioxidant with strong antioxidant power, stability to ultraviolet rays, and long-lasting antioxidant capacity. It can effectively improve various skin dullness, spots, wrinkles and other problems caused by free radicals.

3. How to extract and detect fullerenes in cosmetics？

Fullerenes keeps a good solubility in benzene and xylene, so benzene or toluene is generally used in cosmetics extraction, both are used as chromatographic mobile phase when analyze its content on liquid chromatography.

4. What’s the harm of toluene?

Toluene is a colorless and volatile liquid with a special aromatic smell. Benzene is normally in vapor. After inhalation through the respiratory tract, it will cause the following situations:

       4.1 Acute poisoning

Mainly manifested in neurological symptoms. Excitement or drunkenness occurs in mild poisoning, accompanied by headache, dizziness, nausea, vomiting, etc., severe poisoning can also cause coma, delirium, paroxysmal intense convulsions, narrow pulse, Superficial breathing, lower blood pressure, and death due to respiratory and circulatory failure.

4.2 Chronic poisoning

It manifests as headache, dizziness, memory loss, insomnia, fatigue, etc., which can lead to aplastic anemia. Long-term exposure to high concentrations of benzene may cause leukemia. Toluene and xylene also have a certain impact on fertility.

5.How to prevent toluene volatilization during fullerene chromatographic analysis

AUWII SE series solvent safety caps can effectively prevent the volatilization of toluene in the mobile phase bottle. AUWII dedicated toluene waste collection in a green and safe way, effectively prevents the toluene in the pipeline and the waste liquid bottle from volatilizing outwards. So that protects the health of the analysis and testing personnel in all aspects.
