Car production is increasing every year, and as a result, there’s a growing demand for car washing detergents. A typical car wash shampoo contains at least five ingredients, including surfactant, fragrance, stabilizer, and others.
Surfactant is the main component of car wash shampoo and plays a key role in forming a stable mixture of oil and water when used as an emulsifier. There are four main types of surfactants: anionic, nonionic, cationic, and amphoteric. The challenge in producing car wash shampoo is to achieve the desired performance, appearance, and stability.
In formulation work, statistical experimental design is commonly used to develop a product that meets specifications. The five main surfactants used in car wash shampoo are sorbitan monostearate (SMS), SLES, betaine, cocodiethanolamide CDE), and linear alkyl benzene sulfonates, chosen for their biodegradability. Additionally, the physical properties of car wash shampoo, such as pH, foaming ability, and cleaning power, need to be analyzed and optimized during formulation.
