Application of Laser Particle Size Analyzer in Face Cream

Face cream is a stable system of water, oil, and active ingredients formed by emulsifiers. The size and distribution of active ingredients and oil particles within it are key indicators of its quality.

Testing the particle size distribution of facial creams is crucial as it directly correlates to product stability, skin feel, and efficacy.

1. Impact on the physical stability of the product. Particles that are too large or too widely distributed can easily lead to droplet aggregation and oil-water separation (demulsification), resulting in rough pastes, oil leakage, and other deterioration problems. Uniform and fine particles can form a stable system and extend shelf life.

2. Determine the skin feel and appearance. Particle size typically ranges from tens of nanometers to several microns. The more evenly distributed and smaller the particle size, the finer the paste and the higher its gloss. When applied, it spreads well and penetrates deeply, leaving a silky, refreshing feel. Otherwise, it appears rough and heavy.

3. Related to the delivery and release of active ingredients. Many active ingredients (such as vitamin C and whitening agents) are encapsulated in emulsion droplets, and their particle size affects skin absorption efficiency and targeting. Controllable particle size distribution is the basis for ensuring that active ingredients effectively penetrate the skin and exert their activity.

Therefore, particle size distribution testing is an indispensable part of face cream R&D, quality control, and performance optimization. It comprehensively guarantees product stability, usability, and effectiveness.

This time, Winner2006 is recommended to test the particle size distribution of face cream for customers. It is mainly used to measure the particle size distribution of particles in solid powders or emulsions, such as cement, ceramics, aerosols, suspensions, etc.

Performance Advantage:

1. Large range: the measurement range of Winner2006 is 0.01-1000μm.

2. Wet particle circulation device/optical path automatic centering system: ensures that particles are always in a dynamic dispersion state, and particle size analysis is not limited by any function.

3. Fully automatic mode: The intelligent instrument can test samples with one click.
