Application of fluorescent brightener in detergent

Detergents play an active and effective role in health and hygiene. With the development of society, the continuous improvement of science and technology, and the progress of raw material industry, the detergent industry has developed rapidly. The development of detergent products also indirectly promotes the development of its auxiliary detergent whitening agent, but many manufacturers do not know how to use fluorescent whitening agent in detergent. Today, enmai Xiaobian is going to solve this problem for you.

 

Detergents can be divided into powder detergents, liquid detergents and paste detergents. Different types of detergents have different usage and dosage of fluorescent whitening agents. Powdery detergent is our common washing powder, which is generally manufactured by dry mixing method. The production process and equipment of dry mixing method are relatively simple, the process conditions are mild, and high temperature drying is not required. Therefore, fluorescent whitening agents that can be used for detergents are suitable for this process. Fluorescent brightener is usually sprayed uniformly in the form of solution, soft water suspension or directly added to the detergent mixture in the form of particles. The appearance of the powder is significantly improved by the addition of fluorescent brightener.

 

The manufacturing method of liquid detergent is relatively simple, and its process is mainly stirring and mixing. The fluorescent whitening agent selected has the requirements of good solubility and storage stability. Generally, the fluorescent whitening agent can be directly added in powder form

 

The paste detergent is easy to dissolve in water because it has no dust and is easy to use. The paste is delicate and most of them are white or bright. The fluorescent whitening agent can be added directly in the form of powder or in the form of solution or suspension dissolved in water, water and ethanol.

 

However, the amount of fluorescent whitening agent should be below its yellowing point concentration, which will affect the use effect of detergent. Due to the different types, varieties, dosage forms and contents of active ingredients of fluorescent whitening agents, their yellowing points are also different. Therefore, it is best to determine the yellowing point by small sample test before selection.
