Trajectory Mixing for Cosmetics: Test It with Your Formulations

1. Reproducibility

Challenge: Batch-to-batch inconsistencies endanger quality

K1 Solution:

• Programmed trajectories equal identical processes
• RWTH Aachen confirms excellent repeatability
• Proven in battery slurry trials at PEM
• Very good homogeneity across entire batch

2. Scale-up Problems

Challenge: Lab formulations do not work in production

K1 Solution:

• Same shear forces at every scale
• Same trajectories, same run times
• What works in lab with K1 at three kilogram works in industry with J4
• No tedious re-engineering during scale-up

3. Regulatory Compliance

Challenge: GMP, ISO 22716, FDA compliance required

K1 Status:

• CE certification available
• GMP and ISO 22716 in development
• Dead-space-free design equals hygienic operation
• Validation possible with pilot customers

4. Product Losses

Challenge: One point five to three point five percent loss in pipes and dead spaces

K1 Solution:

• Cylindrical smooth container walls
• Wipe out with spatula or empty with piston
• Minimal residue in container itself
• No complex dead spaces like with agitators

5. Cross-Contamination

Challenge: Product changeover equals contamination risk

K1 Solution:

• Dead-space-free design
• Affordable containers mean many in stock
• Thorough cleaning and disinfection after each run
• Or dedicated container per formulation

Fast Process Times

• Typically less than seven minutes mixing time
• No long heating or cooling cycles
• More batches per day possible
• Same personnel capacity

Energy Efficiency

• Seventy percent less energy in other industries
• No continuous agitator
• Precise temperature control possible
• Homogeneous heating of container

Gentle Process

• No mechanical agitator
• Shear forces through container movement
• Homogeneous distribution across entire mass
• Active ingredients potentially better protected

Maximum Flexibility

• Exchange containers in seconds
• Three emptying methods: spatula, piston, vacuum
• Many containers can be stocked
• Usable for storage
• Small batches equal more SKUs

Easy Cleaning

• Container in dishwasher
• Or thirty second cleaning cycle
• No complex agitator to clean
• Quick product changeovers

Versatile Application

• Viscosity range one to one million mPa·s
• Powders, pastes, liquids
• Potentially: mascara, creams, foundations
• To be tested with your formulations
