Ultrasonic Homogenization Of Cosmetic Mixing Process

Description:

Ultrasonic homogenization of cosmetic mixing process is an effective mixing process in cosmetic production, which can improve the uniformity and stability of products. Select raw materials such as oil phase, water phase, and active ingredients according to the product formula, crush the solid components to ensure their particle size is suitable for homogenization; After mixing the oil and water phases, use an ultrasonic homogenizer with a frequency between 20-40 kHz. Depending on the properties of the mixture, the homogenization time is generally 5-30 minutes; After homogenization, undissolved particles are removed by filtration to ensure the delicacy of the product.

Parameters:

Parameters Influence :

1. Cavitation effect
Low frequency (20-30 kHz):
Cavitation intensity: Low frequency ultrasound generates strong cavitation effects, which can effectively promote the formation and explosion of bubbles in liquids. This strong cavitation effect is more suitable for crushing larger particles and conducting high viscosity mixing.
Applicable materials: good for mixtures with high viscosity or large particles (such as some lotion and suspensions).
High frequency (30-40 kHz and above):
Cavitation intensity: The cavitation effect of high-frequency ultrasound is relatively mild, producing small bubbles that are suitable for fine homogenization and can better handle smaller particle sizes.
Applicable materials: More suitable for delicate products such as cosmetics, drugs, etc., especially in situations where ingredient stability and uniformity need to be maintained.
2. Particle size distribution
Low frequency: can effectively reduce the particle size of larger particles, but may not have a significant impact on the uniformity of small particles, which can easily lead to particle aggregation.
High frequency: More effectively achieving uniform dispersion of fine particles, which can improve the overall uniformity of the product.
3. Temperature control
Low frequency: Due to the high energy generated, it is easy to cause the temperature of the mixture to rise, which may affect the stability of thermosensitive components.
High frequency: usually generates less heat and is more suitable for homogenization of thermosensitive components.
4. Processing time
Low frequency: may require longer processing time to achieve the expected homogenization effect.
High frequency: Usually, good homogenization effect can be achieved in a short period of time, with higher efficiency.
5. Application selection
Low frequency: suitable for products that require strong crushing or mixing, such as food and cosmetics.
High frequency: Suitable for fields such as pharmaceuticals and fine chemicals, especially for applications that require high quality.
