Description

Technical Field

[0001] This utility model relates to the field of freckle cream processing technology, and in particular to a homogenizer for freckle cream production. Background Technology

[0002] A freckle-removing cream is a skin-whitening skincare product that targets skin pigmentation by inhibiting melanin production and accelerating metabolism to lighten spots. Common active ingredients include niacinamide, arbutin, and vitamin C derivatives. It should be used in conjunction with sunscreen to avoid rebound pigmentation. High-quality products should have safety certifications, and the effect usually takes 1-3 months to become apparent. Sensitive skin should choose a gentle formula.

[0003] The production of freckle-removing creams requires the use of homogenizers. The high-pressure shearing force of the homogenizer breaks down whitening ingredients (such as niacinamide and 377) to the nanoscale, improving transdermal absorption and forcibly emulsifying the oil and water phases to prevent layering or crystallization, thus extending shelf life. It also makes the cream smooth and free of particles, reducing skin friction and irritation. The homogenization process directly affects product efficacy and safety and is an essential step in industrial production.

[0004] However, existing homogenizers cannot be automatically cleaned after use. Manual cleaning is troublesome, time-consuming, and labor-intensive. They are also prone to incomplete cleaning and cross-contamination, which affects normal use next time, making them inconvenient to use. Utility Model Content
