Step#1 Raw Material Procurement
The first step in liquid soap production is sourcing the right raw materials. Key ingredients include oils (such as olive oil, coconut oil, or palm oil), an alkali (typically potassium hydroxide), distilled water, and any desired additives like fragrances, colors, or therapeutic agents.
Step#2 Saponification
Once the materials are ready, the process of saponification begins. This involves heating the oils and introducing the alkali. The reaction between oils and the alkali leads to the formation of soap. It’s crucial to monitor the temperature and mixture consistency to ensure optimal saponification.
Step#3 Dilution
Post saponification, the soap mixture is typically quite thick. To achieve the desired consistency for liquid soap, it’s necessary to add distilled water. This dilution step can vary based on the specific formula and desired soap thickness.
Step#4 Additive Integration
After achieving the right consistency, any additional ingredients, such as fragrances, essential oils, colors, or therapeutic agents, are introduced to the mixture. This step customizes the soap to meet specific market demands or client requirements.
Step#5 Quality Control and Testing
At Zeralabs, before packaging, the soap undergoes rigorous quality control tests. These tests ensure that the pH levels are appropriate, and that the soap is free from any contaminants. It also confirms that the soap meets all industry standards and client specifications.
Step#6 Packaging and Distribution
Once liquid soap meets all quality criteria, it’s filled into appropriate containers, labeled, and sealed. The final products are then packaged in bulk containers or pallets, ready for distribution to various businesses or further processing units.
