LS Cosmetic Secures Patent for Innovative Cream Cleansing Foam Technology

LS Cosmetic announced on the 10th that it has registered a patent for its innovative cream cleansing foam manufacturing technology, effectively bolstering its competitive edge in the cleansing category.

This newly patented method focuses on the careful regulation of reaction conditions involving fatty acid-based materials and alkaline solutions during the manufacturing of cream cleansing foams. The precise control of cooling, shear, and maturation processes facilitates the formation of lamellar and hexagonal liquid crystalline microstructures within the formulation. By enhancing texture, stability, and overall product quality, this technology presents significant business implications for LS Cosmetic's product development pipeline.

The patent, titled "Method for Producing Cream Soap with Liquid Crystal Microstructures and Storage Stability," elaborates on an approach that not only improves the sensory experience but also addresses prevalent issues seen in traditional cleansing formulations, such as skin tightness and dryness post-use. These improvements are particularly vital for creating a product that not only cleanses effectively but also retains consumer loyalty through superior after-use performance.

Central to this innovation is the ability to regulate the neutralization rate of fatty acids between 65% and 75%, thereby controlling the balance between soap salts and unreacted fatty acids. This formula design seeks to maintain cleansing efficiency while delivering the creamy, flexible texture characteristic of foam formulations. As buyers increasingly prioritize product performance and post-cleansing skin comfort, this dual focus enhances the brand's value proposition.

By employing a controlled linear cooling process to induce lamellar liquid crystal structures and specific shear conditions to transition to hexagonal phases, LS Cosmetic has addressed both user experience and product stability. The resulting formulation ensures a rich, soft foam quality while minimizing post-cleansing dryness, ultimately promoting consumer satisfaction.

The use of sorbitan and polyglycerin-based surfactants further contributes to the establishment of an emulsifying network, crucial for maintaining uniformity and elasticity during prolonged storage. According to patent documentation, the application of this technology has demonstrated exceptional recovery rates of storage elastic modulus, alongside significant reductions in transepidermal water loss, marking a shift in how cleansing products can enhance skin comfort.

Historically strong in the mask and skincare OEM and ODM sectors, LS Cosmetic plans to leverage this patent as a gateway to expanding its offerings in the cleansing segment. A company representative stated, "This patent is not merely a manufacturing technique but represents a precise formulation design that enhances both usability and product stability. Building on our established expertise in skincare formulation, we aim to maintain a differentiated product strategy within the cleansing category, applying this technology across a range of high-hydration and low-irritation cleansing solutions." The successful registration of this patent underscores the company’s ongoing commitment to advanced formulation technology and paves the way for future innovations in the cleansing product market.
