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 of different viscosities such as water, oils and waxes are combined and dispersed.
Hydrophilic
Washable, quickly absorbed bases: substances of different consistencies are mixed and emulsified, until a fine emulsion is formed.
Requirements for the plant
For pharmaceutical skin care products, hygienic manufacturing and the safe handling of very different viscosities are what count. The following help in particular:
- Specially designed processes for drawing in and incorporating powdered raw materials
- Reversing operation and mixing of highly viscous products in vertical and horizontal directions
- Semi-automatic and fully automatic cleaning and sterilisation equipment
- 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: Manufacturing skin care products
What are skin care products?
Skin care products such as creams, lotions, serums, gels and balms for cosmetics and pharmaceuticals. They are usually emulsions of an aqueous and a lipophilic phase.
How are skin care emulsions manufactured?
The water and oil phases are brought to temperature separately, combined in the vacuum homogenising mixer, emulsified, homogenised and cooled while stirring. Active ingredients and fragrances are added in the cooling phase.
What matters with the plant?
Adjustable shear for fine, stable emulsions, a scraper agitator for high viscosities, powder induction under vacuum, precise temperature control and GMP-compliant CIP cleaning.
What applies to pharmaceutical skin care?
Dermatological products are subject to the requirements of pharmaceutical GMP: qualified plants, validated cleaning, complete batch documentation and hygienic design.
Does SEEFRIED support skin care plants?
Yes, with process consulting, planning, qualification and inspected used homogenising mixers for creams, lotions and gels.
