Pipes and fittings for the cosmetics industry: characteristics, materials, and solutions for safe and hygienic processes

The cosmetics industry requires high standards of hygiene, safety, and process control. Creams, emulsions, gels, lotions, and semi-dense products require reliable transfer lines that are easy to sanitize and compatible with a wide range of chemicals.

Ensuring the reliability and consistent quality of final products depends on a crucial choice: hoses and fittings suitable for the cosmetics industry . Therefore, the selection must be guided by in-depth technical knowledge and strict compliance with international regulations and certifications. Universalflex guides you through the criteria that define a safe process.

The challenge for the cosmetics sector: when and why the implant makes the difference

Transfer components must handle products with extremely variable and delicate operating conditions. The main application challenges our hoses address include:

• High viscosity transfer: management of creams, gels and pastes between tanks, reactors and filling machines
• Dosing precision: lines dedicated to oils, essences and fragrances, where the slightest alteration is unacceptable
• Production lines for detergents and liquid soaps
• Thermal control: transport of thermolabile creams or processes that require constant temperature maintenance
• ATEX safety: certified connections in areas with risk of explosion, often in the presence of alcoholic vapours or solvents

In any context, the use of certified, hygienic pipes made of materials compatible with the products being treated is essential.

Tubes for the cosmetics industry: the most commonly used materials

There is no single material: the optimal choice depends on the formula, viscosity and cleaning cycles.

PTFE (Polytetrafluoroethylene): the unbeatable for absolute purity

PTFE is among the most sought-after materials for its advanced properties:

• In total area total anti-adhesive: creams and cosmetics flow without residue or cross-contamination.
• Maximum chemical resistance: compatibility with solvents, oils, aggressive substances and products with high alcohol concentrations.
• No permeability: the product can stagnate temporarily without absorbing odors or alterations.

It is an ideal solution for processes that require maximum purity and extreme sanitizability.

Silicone: high temperature flexibility

Silicone is useful where movement and thermal resistance are needed:

• High flexibility and maneuverability: perfect moving lines, vibrating or continuously moving machinery.
• Resistance ad high temperature: ideal for frequent sterilizations.
• Availability with pharmaceutical certifications: often requested in high-end cosmetics.

It is particularly suitable for delicate doses and sensitive products.

Polyethylene (PE): the efficient choice for semi-finished products

Polyethylene offers a more economical solution than silicone and PTFE:

• Property anti-adhesive: prevents organoleptic alteration and facilitates flow.
• Cost-Effectiveness: widely used for detergents, cosmetic bases or semi-finished product lines where the product temporarily stagnates.

NBR rubber: resistance to oils

NBR rubber offers:

• Excellent oil resistance: ideal for oily and greasy cosmetic products.
• Reliability: wide spectrum of use in different operating conditions.

It is a versatile choice for general transfer lines.

Pipes certified for safety and compliance

In the cosmetics sector, compliance with standards that guarantee the safety of consumers and the production environment is often required:

• FDA e MOCA, for safety in processes that come into contact with products intended for skin.
• ATEX, in environments where alcohol or solvent vapours may be present which pose a risk of explosion.

Universalflex supplies pipes that are fully compliant with these directives, eliminating risks and ensuring maximum safety at every stage of the process.

Electro-heated tubes for temperature maintenance

Some cosmetic products require controlled temperatures to preserve viscosity, stability, and chemical-physical properties.
To meet this need, we supply pipes with electric heating sheath, a solution that allows:

• Thermal maintenance: the temperature is constant, from the beginning to the end of the transfer.
• Quality control: prevents solidification or separation of emulsions and alterations.
• Efficiency: improves product fluidity, optimizing the speed and stability of the production line.

Fittings for the cosmetics sector

The quality of the connection is as important as that of the piping.
In cosmetics, hygiene is guaranteed by stainless steel and our connection technique:

• BS Clamp Fittings in 316L stainless steel.
• In some cases, DIN 11851 fittings, 11853 and 11864, hygiene standards typical of the food and pharmaceutical sectors.

To ensure the highest level of hygiene, Universalflex supplies pipes already connected by pressing.

This process avoids stagnant areas and ensures:

• Aseptic finishing
• Maximum cleanliness
• Process safety
• Longer system life

FAQ

1. Which materials are best suited for tubes used in the cosmetics industry and why?

In the cosmetics industry, the leading materials are PTFE, silicone, polyethylene, and NBR rubber. PTFE is preferred for its maximum chemical resistance and non-stick properties, crucial for creams and oils. Silicone excels in flexibility and high temperature resistance, while NBR rubber is the optimal choice for oil-based products.

2. Why is it important to use 316L stainless steel hygienic fittings in the cosmetics industry?

Fittings such as the BS and DIN Clamp in 316L stainless steel They guarantee maximum hygiene, corrosion resistance and compatibility with cosmetic processes that require high standards of cleanliness.
Universalflex's use of the pressed fitting eliminates stagnant areas (crevice-free), ensuring an aseptic finish and greater safety throughout the line.

3. Can cosmetic tubes maintain product temperature?

Yes. Universalflex offers hoses with electric heating sheath to maintain the constant temperature of thermolabile creams, gels and emulsions.
This solution is essential to preserve viscosity, prevent product spoilage, and optimize process continuity.
