Champ d’application

This standard applies to special toilet soaps manufactured with added antibacterial or bacteriostatic agents, providing both cleaning and antimicrobial functions. It is specifically designed for soaps claiming to inhibit bacteria and is categorized into broad-spectrum and common types based on their efficacy. This standard does not apply to regular toilet soaps without added antibacterial agents. It references the general requirements of QB/T 2485 for basic sensory and physicochemical properties.

Exigences techniques

The standard outlines specific technical requirements for special toilet soaps, focusing on raw materials, physicochemical properties, and mandatory hygiene indicators. Section 5.3 of this standard is designated as mandatory, requiring strict compliance with bacteriostatic efficacy. The raw materials, including antibacterial agents and preservatives, must comply with relevant national regulations. The sensory and physicochemical indicators must meet the specifications outlined in QB/T 2485. The core requirement defines the bacteriostatic efficacy based on the soap type. Broad-spectrum bacteriostatic soaps must completely inhibit the growth of specified strains including Staphylococcus aureus, Escherichia coli, and Candida albicans. Common bacteriostatic soaps are only required to inhibit Staphylococcus aureus. Manufacturers must clearly label the category of the special toilet soap on both large and small packaging.

Méthodes d’essai

Testing involves preparing the sample by cutting and mixing the soap, followed by a bacteriostatic test. The procedure includes culturing specific bacterial strains in a trypticase soy agar medium, preparing test and control petri dishes with a 0.1% soap solution, and incubating at 37°C for 48 hours. The test evaluates whether bacterial growth is inhibited in the test dishes while confirming viability in the control dishes. An informative annex (Annex A) also provides methods for determining the content of common bactericides like Triclosan and Triclocarban using gas chromatography and spectrophotometry.
