About This Test

Toilet Soap Liquid (IS 4199:2001) refers to a liquid formulation intended for personal hygiene, designed primarily for cleansing the skin. It is typically composed of synthetic or natural surfactants, moisturizers, fragrances, and preservatives. Unlike solid toilet soap bars, liquid toilet soap offers convenient dispensing, better hygiene due to reduced microbial contamination, and ease of use, particularly in public or shared settings.

This standard (IS 4199:2001) governs the requirements and testing methods for liquid toilet soap to ensure it meets safety, performance, and quality parameters suitable for daily human use.
