salol

Thân thiện

A pharmacist carefully measures salol powder to coat a batch of pills.

Definition

Noun: A synthetic, white crystalline powder (phenyl salicylate) with a pleasant taste and odor. It is used for various purposes, including absorbing ultraviolet light in sun tan lotions, acting as a preservative or antiseptic, and as an enteric coating for pills to ensure the medicine is released in the intestines rather than the stomach.

Usage

Salol is a specific chemical compound used primarily in pharmaceutical and cosmetic formulations. - Its enteric coating property is crucial for protecting stomach-sensitive drugs. - Its light-absorbing quality makes it useful in early sunscreen products. - Its antiseptic property allows for its use as a mild preservative.

Examples

• The pharmacist explained that the tablet's salol coating would prevent it from dissolving in the acidic stomach.
• Early sun protection formulas often contained salol to filter harmful rays.
• As an antiseptic, salol was sometimes used in topical ointments.

Advanced Usage

• Chemical Synthesis: Salol is formed by the esterification of salicylic acid and phenol. It is hydrolyzed in the small intestine to release its component acids, which is the basis for its enteric coating action.
• Historical Context: Its use has declined with the development of more modern and effective compounds, but it remains a classic example in pharmaceutical chemistry.

Variants and Related Words

• Phenyl salicylate: The systematic chemical name for salol.
• Enteric coating: A general term for a protective polymer coating that resists stomach acid, a key application for salol.
• Ester: The class of organic compounds to which salol belongs.

Synonyms

• Enteric coating agent (functional synonym in one context)

Notes

Salol is a specialized term from chemistry, pharmacology, and cosmetic science. It is not commonly encountered in everyday language but is important in technical and historical contexts within these fields.
