Every minute, your skin loses between 30,000 and 40,000 dead skin cells. This means losing millions of cells every day, which makes your skin look less glowing. Being a moisturizing agent, body lotion has the power to hydrate your skin and give the glow back to it. Production involves water and oil phases, which you then mix with an emulsifier and blend until homogeneous. Preservatives are essential for any solution containing water for the prevention of microbial growth.

Transforming your production process with body lotion making equipment
In the first stage of body lotion production, you prepare and mix the oil and water-soluble ingredients separately. You start with your dry ingredients, such as cetyl alcohol in the form of flakes or powder, sometimes blended while dry. You will usually add emulsifiers and stabilizers to the water phase, while powders and flakes may mix better with your chosen oil. Some ingredients mix better when heated so that you might consider body lotion making equipment such as kneaders, dispersers, and homogenizers fitted with temperature control capabilities.
Even so, you should take care to add active ingredients after steps involving elevated temperatures to avoid degradation. Once the two phases are thoroughly mixed, you bring them together in a homogenizer machine to reduce particle size and develop an evenly distributed mixture. You will then mix this final combination until the body lotion preparation is entirely uniform.
How can you avoid the formation of agglomerates in your mixtures?
When dispersing powders into liquids in the body lotion making process, agglomerates might form – this can affect the texture and performance of the final product. Agglomerates can certainly be filtered out at the end of the process, but the best way to ensure the quality of the final product is to avoid their formation. The problem is that they can resist breakdown by conventional agitators. These clumps of ingredients will form primarily on the surfaces of your body lotion making equipment where conventional agitators are unable to exert the necessary shearing forces for reconstitution.
Various agitators exist to address mixtures of different viscosities and formulations prone to the formation of such aggregations. As a result, you may require specialized bladed agitators such as high shear mixers for mixtures that are prone to the formation of such agglomerates.
How water forms the distinction between creams and lotions
In essence, the question of cream or lotion is one of water content, as water directly affects the viscosity of the formulation. Lotions will consist of more water, while creams contain more oil. Practically, this means that dry skin will benefit more from creams, while lotions are better suited to oily skin. A thinner formula is less likely to clog pores, while a thicker formula provides a protective barrier to lock in moisture. Body lotions will generally be easier to homogenize, while creams are more likely to require specialized equipment. Of course, this will depend heavily upon your chosen formula and the properties of its ingredients.
Hurdles to homogenization and how emulsifiers can help
By nature, oil and water are an unlikely pair. Mixing the two is virtually impossible without an intermediary to bridge the gap. For this reason, emulsifiers are essential to the production of body lotion. These amphipathic molecules have both polar and nonpolar aspects, allowing them to bind to both. It’s this property that facilitates the mixture of two otherwise immiscible liquids. If you’ve tried to wash oil from your hands with water alone, you’ve seen this principle in action. The addition of soap, a very common emulsifier, will mix with the oil and wash right off.
