Application of microencapsulation technology in cosmetics
As people's understanding of cosmetics improves, consumers, while pursuing beauty, are increasingly inclined to choose safe, healthy, and professional products. Therefore, applying cutting-edge biotechnology to the cosmetics field is gradually becoming a guiding direction for the continuous advancement of the cosmetics industry, and "microencapsulation technology," a research hotspot in the cosmetics field, is a prime example.
What exactly is microencapsulation technology?
Microencapsulation technology uses certain technical methods, innovative processes, and specific equipment, employing natural or synthetic polymeric materials to encapsulate tiny particles of solids, liquids, or gases within microcapsules with a semi-permeable or sealed membrane diameter of 1-500μm.
The substances within the microcapsules are isolated from the external environment, protecting them from environmental influences and enhancing their stability. Under appropriate conditions and methods, the encapsulated substances can achieve controlled release.
In the 1960s, this technology was widely used in the pharmaceutical field because it could mask unpleasant odors, improve stability, reduce irritation, and, particularly, enable slow, controlled release. In the last 20 years, microencapsulation technology has developed in the cosmetics industry and is favored by brands.
This technology has excellent transdermal absorption rates, prolonged retention time at skin target sites, and good stability. It has low-cost, high-efficacy applications in the cosmetics, functional food, and pharmaceutical fields.

Cosmetics Observation | Microcapsule Technology - Another Growth Point in the Era of Effective Skin Care?
In the era of efficacious skincare, consumers' focus on a product is no longer limited to the ingredient list. Instead, they are more interested in whether the formula can truly deliver its claimed efficacy, including whether the active ingredients can remain active and to what extent they can be absorbed by the skin. These consumer concerns are also the difficulties in the R&D of efficacious skincare products, and microencapsulation technology is one of the solutions.
