Patent Registered for Lotion Formula Enhancing Exfoliation While Minimizing Skin Burden

Narice Cosmetics Co., Ltd. (Representative: Hiroyoshi Muraoka, Headquarters: Fukushima-ku, Osaka) has successfully developed a formula for an exfoliating lotion that enhances exfoliation while minimizing skin burden, achieving two seemingly contradictory effects. The company has now registered a patent for this development, and the details are summarized below.

[Background Research and Current State of Exfoliating Lotions]

In 1937, six years after its founding, our company launched its first exfoliating lotion, "Narice Conc," with the aim of improving the penetration of subsequently used lotions by removing aged keratin. Since then, we have continuously conducted research on the stratum corneum and exfoliating lotions. For our company, whose name originates from the English word "nourishment," research on the stratum corneum and exfoliating lotions is core to our business. In recent years, we have strived to improve our technology through multifaceted research, including establishing methods to quantify the comfort experienced when using exfoliating lotions, utilizing AI to assess the condition of the stratum corneum, and successfully developing plant-derived ingredients with unique exfoliating effects. We have presented our findings at academic conferences both domestically and internationally.

1937: Exfoliating Lotion "Narice Conc"

Exfoliating lotions are intended to remove aged keratin, and alkaline cosmetics are generally known for this purpose. Alkaline cosmetics contain alkaline ingredients that enhance the penetration of water and water-soluble components into aged keratin, making it easier to remove. However, they can cause irritation for sensitive skin, raising safety concerns. Furthermore, exfoliating lotions are typically used by wiping with cosmetic tools such as cotton pads. While wiping with cotton can physically remove aged keratin, it also poses a challenge due to the irritation caused by friction. Even in our past research, it has been difficult to increase the ability to remove aged keratin without burdening the skin.

[Details of the Patent]

The technology for which a patent has now been registered involves compounds of phosphoric acid and higher alcohols with a linear structure, and their salts. By appropriately adjusting the neutralization degree with alkaline compounds, this technology realizes an exfoliating lotion that can remove aged keratin while suppressing skin irritation and friction burden. We have confirmed clear differences using this research product and a comparative cosmetic formulation, measured by static friction coefficient using a surface property tester and through sensory evaluation by expert panelists. Furthermore, we confirmed that the research product was superior in the amount of aged keratin removed when wiped with cotton. In addition, a one-week usage test was conducted on 10 monitors who had experienced skin trouble with previous exfoliating lotions, and no skin irritation occurred in any of the 10 participants. This technology is expected to restore the skin's natural moisture and smoothness, and improve dullness.
