Development of Traditional Chemical Dyes

The researchers of Alfa Chemistry attribute all reagents that can be used for dyeing to dyes. For traditional dyes, in addition to common chemical dyes such as acid dyes, basic dyes, solvent dyes, they also include those used in food dyeing. Food coloring and dyes applied in life such as hair dyes and cosmetics. Alfa Chemistry has a sound quality assurance system, can strictly supervise the quality of products, and can provide customers with high-end and high-quality traditional chemical dyes.

The Services

In Alfa Chemistry, the researchers expanded the scope of traditional chemical dyes, in addition to typical chemical dye reagents, it also includes common dyeing reagents in life, such as hair dye reagents. We always adhere to the purpose of meeting the needs of customers. The development services for traditional dyes we can provide include but are not limited to the following categories:

• Development of acid dyes
• Development of basic dyes
• Development of solvent dyes
• Development of food coloring
• Development of dyes used in life

We have expanded the category of traditional dyes and classified all products that can be dyed into the category of traditional dyes. Alfa Chemistry's researchers insist on focusing on customers' needs and insist on developing traditional chemical dyes that meet customers' needs. Our researchers are also familiar with advanced technologies and methods, and can accurately characterize and test traditional dyes.

Traditional Chemical Dyes

Acid dyes (anionic dyes): These dyes refer to dyes containing acidic groups, which can be combined with protein fibers and are suitable for dyeing under acidic or rejuvenating conditions.

Basic dyes (cationic dyes): salts of positively charged pigments, hydrochloric acid, and oxalic acid.

Solvent dyes: The dyes can be dissolved in organic solvents and can be divided into oil-soluble dyes and alcohol-soluble dyes.

Food coloring: It belongs to food additives and can be used for coloring on food. Can be divided into artificial colors and natural colors.

Dyeing agents in life: hair dyes, make-up, cosmetics, etc.

Service Principle

• Alfa Chemistry always insists on meeting customers' needs with high quality, honest and efficient service.
• Always adhere to the goal of meeting the needs of customers.

Professional and Accurate Quality Inspection Platform

Instruments: Accurate and complete equipment, which can identify the types of dyes developed, optical testing, component analysis, formula research, etc.

Experienced researchers: Researchers who have been working for many years can solve a variety of practical problems and make reasonable judgments and decisions

High-quality cooperation team: We cooperate with top teams and master leading technologies and means

Development Service Process of Traditional Dyes

• Determine the target dye product: It is necessary to understand the customer's expectations for the product, performance, attributes, uses, cycle time and cost, etc.
• Data review: Starting from the existing products, check the performance, stability and industry specifications of the target product to determine the key attributes of the dye product
• Solution: Preliminarily determine the synthetic route, sign a contract and confidentiality agreement with the customer and pay a deposit
• Small sample test: usually carried out in the laboratory, mainly for formula research, which needs to be tested
• Confirm the production route: If the above tests meet the customer's needs, it is necessary to enlarge the process and optimize the parameters. At the same time, it may be accompanied by the replacement of raw materials and the optimization of the route.
• Mass production: The above process will be communicated with the customer throughout the process. After the customer pays the final payment, we will produce dye products in batches according to the customer's needs. We will issue a certificate of conformity for the product and also support third-party testing. The above cycle will be adjusted according to the difficulty of product development.
