RELX Announces Patent for Resin Extract, Preparation Method, and E-Liquid

Summary of Resin Extracts, Preparation Methods, and E-Liquids<\/p>

This application relates to resin extracts and their preparation methods, as well as e-liquids containing them. Some embodiments of the resin extracts in this application contain 20wt.% to 95wt.% benzoic acid, 0.1wt.% to 5wt.% vanillin, and 0.1wt.% to 3wt.% phenethyl alcohol or benzyl alcohol, and optionally contain at least one of the following substances: 0.05wt.% to 20wt.% cinnamic acid, 0.05% to 0.5% benzyl cinnamate, 0.03wt.% to 0.1wt.% benzyl benzoate, 0.05% to 2.1% nerolidol, and 0.05wt.% to 0.1wt.% benzoic acid cedar resin. The resin extracts in this application can be used in e-liquids as substitutes for benzoic acid, effectively enhancing user experience.<\/p>

Benzoic acid was first discovered by the French in 1618. Benzoic acid (C7H6O2) is an aromatic carboxylic acid and the simplest aromatic acid.

Initially, benzoic acid was obtained by dry distillation of benzoin or hydrolysis of sodium benzoate. Industrially, it is commonly produced from toluene, ortho-xylene, or naphthalene, which can be obtained from coal tar or petroleum. Additionally, benzoic acid can be a byproduct of producing benzaldehyde from toluene. The main industrial production methods for benzoic acid include toluene liquid-phase air oxidation, hydrolysis of trichlorotoluene, and decarboxylation of phthalic anhydride, as well as benzyl halide oxidation methods.

Benzoic acid has three common uses in food and pharmaceuticals: as a preservative, a drug, and a flavoring agent.

Chinese food industry analyst Zhu Danpeng stated in a report that benzoic acid is a chemical substance, and any chemical substance in excess is certainly harmful. If e-cigarettes are treated as food, adding benzoic acid still has side effects, depending on national standards.<\/p>

The resin extracts and their preparation methods and e-liquids patent announced by RELX indicates that resin extracts can be used in e-liquids as substitutes for benzoic acid, effectively enhancing user experience.

The specific effects still require more experimental data to prove. Only through the continuous efforts of more electronic vaporization practitioners can the industry develop in a healthier direction.
