Non-rinse animal shampoo / Zainatul Fadhilah Zulkarnain

The non-rinse animal shampoo is a shampoo that does not need any water to be applied on the animal skin before or after bathing them. This can ease the personnel when handling their pets during bath as pets especially cats are afraid of water, and reduce harm or misbehave of pets towards the caretaker. It also decreases the water consumption used in bathing of pets. In countries of low climate temperature, no heating of water is needed and this saves electricity. The use of non-rinse shampoo is simple and quick. It implies that such products can be applied onto the homeless animals in petcare activity. This study identified formulation of non-rinse animal shampoo via journal and patent information, as well as, laboratory formulation study. The study first evaluated the critical ingredients required in the said product, namely therapeutic, surfactant, co-surfactant, preservative, moisturizer and liquid vehicle. The nanoemulsion was formulated through simple mixing of tocopheryl acetate (therapeutic) and polysorbate 20/sodium lauryl sulphate (surfactants) followed by homogenization. The nanoemulsion pH, surface tension, viscosity, physical appearance, size distribution and zeta potential were characterized against water when required. It had lower surface tension and viscosity than water which implied good spreading property during lathering. The pH of the developed shampoo is near neutral which suggested reduced skin irritation. The nano feature of the emulsion (less than 100 nm) was envisaged to promote its cleaning activity and therapeutic delivery.
