Liquid soap – all-purpose cleaning liquid

Almost everyone has a bottle of liquid soap in their bathroom. One could even say that, it was a necessity at the start of the COVID-19 pandemic. Soaps in liquid form have been around since the 19th century. The main purpose of liquid soap is to remove dirt, germs and bacteria from the hands, but thanks to additional ingredients, soap also cares for, moisturises and nourishes the skin.

Liquid soap is a detergent made up of surfactants and other ingredients. Soap can be manufactured on a large scale or made at home. Professional machinery is required for mass production.

Production of liquid soap – how is this cleaning product made?

Production of liquid soap on an industrial scale is a multi-stage process that requires not only a great deal of knowledge but also state-of-the-art technology. How is liquid soap produced? 

Step 1. Recipe 

The creation of a recipe is the first step in the production of liquid soap. Water, surfactants, which are responsible for the lathering of soap, and a variety of active ingredients, such as vitamins, essential oils or extracts, are used to make liquid soap. Water is crucial for soap making. It must be demineralised and treated in order for the product to be of the highest quality.

Step 2. Testing

Once the recipe has been developed, the liquid soap must be tested. Application and apparatus tests are carried out in the laboratory. Only when these are positive can the soap be mass-produced.

Step 3. Mixing plant

After the raw materials are delivered and unloaded, they are weighed and dosed into the mixer. This process is done automatically by machines.

Step 4. Quality control

A sample of the liquid soap created in the mixer is then sent to the Quality Control Department in order to check its quality and compliance with the specifications. The density, colour, viscosity, smell and pH are all evaluated. If the product passes the test, it can be bottled. The soap is then transported to storage tanks, where it will be bottled.

Step 5. Bottling plant

Production lines are used to bottle the liquid soap. These lines differ depending on the type of packaging. It includes standard bottles as well as supplementary packaging. Packaging can be made in-house or by an outside supplier. An automated dispensing line pours the liquid soap into the container.

Step 6. Capping and labelling

After the bottles have been filled, they are capped by a capping machine and labelled with a labeller.

Step 7. Quality control

Before the product goes on sale, another quality check is carried out just after it comes off the production line. This is a random inspection of the finished product to ensure that it meets the specifications.

Step 8. Storage and transport

Following the quality control, the products are packed and transported to the warehouse. From there, they are transported to stores where the liquid soap can be purchased.
