Ultrasonic homogenization serves as an efficient mixing method for cosmetic manufacturing, enhancing product uniformity and stability.

 

First, select raw materials including oil-phase components, water-phase materials and active ingredients in accordance with the product formulation. Pre-grind solid raw materials to achieve a particle size suitable for homogenization.

 

Once the oil and water phases are combined, process the mixture using an ultrasonic homogenizer operating at 20–40 kHz. Homogenization duration typically ranges from 5 to 30 minutes, adjusted based on the characteristics of the blend.

 

Following homogenization, filter the mixture to eliminate undissolved particles and guarantee a smooth, fine texture of the finished cosmetic product.

 

 

 

1. Cavitation Effect

 

Low Frequency (20–30 kHz)

Cavitation intensity: Low-frequency ultrasound delivers strong cavitation action, driving the generation and collapse of microscopic bubbles within liquid media. This powerful cavitation force works well for breaking down large particles and processing high-viscosity mixes.

Suitable materials: Blends with high viscosity or coarse particles, including certain lotions and suspensions.

 

High Frequency (30–40 kHz and above)

Cavitation intensity: High-frequency ultrasound creates gentler cavitation with finer bubbles. It is ideal for fine homogenization and handles smaller particle sizes effectively.

Suitable materials: Well-suited for premium refined products like cosmetics and pharmaceuticals, especially applications requiring consistent ingredient stability and homogeneity.

 

2. Particle Size Distribution

 

Low-frequency treatment efficiently reduces the size of coarse particles, yet it often struggles to evenly distribute fine particles and carries a higher risk of particle re-agglomeration.

 

High-frequency processing achieves more uniform dispersion of fine particles and improves the overall homogeneity of the final product.

 

3. Temperature Control

 

Low-frequency operation releases high energy, which tends to raise the temperature of the mixture. This heat buildup can compromise the stability of heat-sensitive active ingredients.

 

High-frequency ultrasound generally produces less heat, making it the preferred option for homogenizing thermosensitive materials.

 

4. Processing Time

 

Low-frequency homogenization often requires longer run times to reach the target homogenization quality.

 

High-frequency setups typically deliver satisfactory homogenization results in shorter cycles for better throughput.

 

5. Application Guidance

 

Low frequency: Recommended for formulations demanding strong particle breakdown or heavy-duty mixing, such as food and thick cosmetic systems.

 

High frequency: Preferred for pharmaceutical and fine chemical applications, particularly high-specification processes requiring superior finished product quality.
