Most makeup products contain oil-based ingredients and colorants such as pigments, which are hydrophobic. This makes it necessary to use oil-based solvents, such as cleansing oils, balms, and creams to remove them.

However, this cleaning process can potentially irritate the skin. Additionally, the company believes consumers are looking for a faster and easier cleaning method.

To solve this problem, the company first turned to a temperature-sensitive polymer that forms a hydrophobic film on the skin but changes structure and detaches from the skin when it reaches a certain temperature.

Such technology is similar to what has been used in film or tube type mascaras, which claim to be durable and smudge-free, but are easily washed off with lukewarm water.

However, it was observed that the polymer base fell apart, thus affecting the cleaning experience. For example, it made it difficult to remove makeup clogged with pores and wrinkles.

The right material

Biocellulose is a cellulose microfibril synthesized from bacterial cellulose which is mainly used in cosmetics in sheet or gel masks. This material has high crystallinity, is thin and yet has a higher physical strength than cellulose of plant origin.

Since biocellulose can be difficult to apply to cosmetic formulations, the company thought of applying a method of dispersing the biocellulose in an aqueous solution while maintaining the network of biocellulose microfibrils.

As a result, the biocellulose coated cosmetic composition forms a uniform film on the skin, even on uneven surfaces such as pores and wrinkles.

Once in contact with water, the dense network of microfibrils becomes entangled and detached from the skin together, thus “perfect cleaning is made possible without strong detergent ”,said the firm.

However, the easily removable characteristics of this film also meant that it would have a weaker hold on the skin.

For this patent, the company combined the cellulose microfibril with a film-forming polymer of polyvinyl alcohol to enhance the formation of the film on the skin.

“By including polyvinyl alcohol as a film-forming polymer in addition to the biocellulose microfibrils in the basic cosmetic composition, the film formed more strongly.”

The document suggests that lukewarm water in the range of 25 to 45 degrees is best suited for cleaning the processed cosmetic formulation from the skin as it helps dilate blood vessels and aid blood circulation to facilitate cleansing and exfoliation. while cleaning the skin.

The biocellulose composition can be applied to a range of cosmetic products, from basic makeup products to sunscreens as well as skin care products. It can work as a liquid, cream or spray.

The patent suggests that the composition can act as a separate base to improve adhesion to other colored cosmetics like eye shadow while also improving the removal efficiency.

Additionally, it may contain active ingredients as well and the company suggests that it would work well with a moisturizing component.
