Alcance y aplicabilidad

This standard applies to the food additive Propyl p-hydroxybenzoate, synthesized via esterification using p-hydroxybenzoic acid and propanol with a sulfuric acid catalyst. It is specifically designed for products utilized as preservatives in the food, pharmaceutical, and cosmetic industries. Manufacturers producing this preservative for the Chinese market must strictly adhere to these guidelines.

Requisitos técnicos

The standard outlines the physical and chemical parameters for Propyl p-hydroxybenzoate, requiring it to be a white crystalline powder with specific sensory characteristics. It sets strict acceptable ranges for the primary assay content, melting point, and limits for free acid and sulfates. Critical mandatory safety limits are established for arsenic and heavy metals (as Pb) to ensure consumer safety. Additionally, the standard defines thresholds for loss on drying and ignition residue to guarantee product stability and purity.

Métodos de ensayo

The standard mandates specific analytical procedures, including titration using a pH meter to determine the main assay content, and capillary tube methods (as the arbitration method) or digital melting point instruments for melting point determination. Strict analytical protocols are required for impurity testing, including the arsenic spot method and specific colorimetric tests for heavy metals. Verification of physical properties and impurities heavily references national standard reagent testing methods, such as GB/T 617 and GB/T 9741.

Preguntas frecuentes

What products are regulated under GB 8851-2005?

This standard applies to propyl p-hydroxybenzoate produced via esterification using p-hydroxybenzoic acid and propanol. It is primarily used as a preservative in food, pharmaceuticals, and cosmetics.

Are there any updates from the previous version of GB 8851-2005?

The 2005 version updated the assay limits to 99.0%~100.5%, modified the arsenic limits to be stricter, and replaced indicator-based titration endpoints with a pH meter. It also restructured the inspection rules into type testing and delivery testing categories.

How does GB 8851-2005 differ from international standards?

GB 8851-2005 is modified adopted from the Japanese Food Additives Codex (7th Edition, 1999). However, it features stricter arsenic content requirements and utilizes a pH meter for titration endpoints to reduce analytical errors.
