Since the reform and opening up, China's cosmetics market has experienced rapid growth, with an average annual sales increase of 23.8% over the years. By 2012, despite challenges from both domestic and international markets, the retail sales of cosmetics by large-scale enterprises in China still rose by 17.0% year-on-year. However, this marked a slight decline compared to 2011, as the overall economic environment slowed down. In response, the market now demands higher quality across all cosmetic categories.
Cosmetics typically come in powder or emulsion forms, and their performance is influenced by factors such as particle size, shape, flowability, emulsion stability, and ingredient composition. As regulations on cosmetic ingredients become stricter, especially regarding particle size-related components like antiperspirants, hair gels, toothpaste, facial care products (such as lipsticks, mascaras, eyeshadows), nail polish, and more, controlling particle size has become critical.
Take deodorants and hair sprays, for example. If the particle size of the antiperspirant is too small, it may not effectively block pores, leading to reduced effectiveness. Similarly, the softness and retention of hair gel depend heavily on the particle size of the gelatin used. If the particles are too fine, they can be inhaled by users, posing a safety risk.
In toothpaste, particle size plays a key role in determining its performance. Common ingredients include abrasives like calcium carbonate and whitening agents such as titanium dioxide. The distribution of these particles directly affects the color and plaque-removal efficiency of the product.
Facial products like lipstick, mascara, and eyeshadow also rely on precise particle control. The color intensity of lipstick is determined by the type and particle size distribution of the pigment. A broader range of particle sizes can create a more frosted effect, while finer particles influence adhesion and color uniformity. For eyeshadows, smaller, evenly distributed particles ensure better blending with the skin, longer wear, and reduced eyelid creasing.
Mascara often contains filaments that enhance lash length and strength. Proper particle size control helps maintain curl and prevent lashes from falling out. The wider the particle size distribution of additives, the more likely they are to separate or fall off during use.
In summary, particle size testing has become essential in cosmetic R&D. Traditional chemical methods are being replaced by advanced instrumental techniques, with laser particle size analyzers becoming the industry standard due to their speed, accuracy, and reliability. Since China's "7th Five-Year" scientific program, the particle testing sector has grown rapidly, with many companies developing high-quality solutions. The WINNER2308 dry-wet integrated laser particle size analyzer from Jinan Micro-Nano is widely used in R&D and production, offering excellent results and gaining recognition in the cosmetics industry.
