Skin care products are manufactured for both the pharmaceutical and the cosmetics sector. They are usually multi-phase preparations with lipophilic and aqueous phases that are applied directly to the skin.
Hydrophobic and hydrophilic preparations
Hydrophobic
Greasy, water-repellent emulsions: substances with different viscosities such as water, oils and waxes are combined and dispersed.
Hydrophilic
Washable, quickly absorbed bases: substances with different consistencies are mixed and emulsified until a fine emulsion is formed.
Requirements for the plant
For pharmaceutical skin care products, hygienic production and safe handling of very different viscosities are essential. The following features help in particular:
- specially designed processes for inducting and incorporating powdered raw materials
- reversing operation and mixing of highly viscous products in vertical and horizontal directions
- semi- and fully automatic cleaning and sterilisation systems
- production under vacuum for products with as little air as possible
In addition, several production steps can be combined in one operation. This saves material and production costs.
FAQ: Producing skin care products
What are skin care products?
Products such as creams, lotions, serums, gels and balms for cosmetics and pharmaceuticals. Most are emulsions of an aqueous and a lipophilic phase.
How are skin care emulsions produced?
Water and oil phases are heated separately, combined and emulsified in a vacuum homogenising mixer, homogenised and cooled while stirring. Actives and fragrances are added during cooling.
What matters in the process plant?
Adjustable shear for fine, stable emulsions, a scraper agitator for high viscosities, vacuum powder induction, precise temperature control and GMP-compliant CIP cleaning.
What applies to pharmaceutical skin care?
Dermatological products are subject to pharmaceutical GMP: qualified equipment, validated cleaning, complete batch documentation and hygienic design.
Does SEEFRIED support skin care projects?
Yes, with process consulting, planning, qualification and inspected used homogenising mixers for creams, lotions and gels.
