This invention discloses a novel method for preparing a clean fuel additive, relating to the field of clean fuel additive technology. Its components include: a main cleaning agent: Mannich base; a dispersant: polyetheramine; a surfactant: highly active polyisobutylene; an antioxidant: N,N-di-sec-butyl-p-phenylenediamine; an octane booster: dimethyl carbonate; a solvent: 120# solvent oil; a combustion improver: C9-C11 mixed olefins; a stabilizer: trimethylolpropane; an ignition promoter: nitrobenzene; and auxiliary additives: n-dodecane, sodium polystyrene sulfonate, and eugenol methyl ether. This invention achieves a significant synergistic effect among the core components such as Mannich base, polyetheramine, polyisobutylene, amine antioxidants, and dimethyl carbonate. This synergistic effect allows the additive to comprehensively optimize the cleanliness, anti-knock properties, stability, and combustion efficiency of fuel at a relatively low total addition amount.

This invention discloses a lip mask composition and its preparation method. The lip mask composition comprises a film-forming agent, a thickener, an emulsifier, oil, and water. The film-forming agent comprises polyvinyl alcohol with a viscosity of less than 35 mPa·s, sodium polystyrene sulfonate, and *Pteris vittatum* polysaccharide. The thickener comprises sodium alginate and lithium distearate dimethylammonium montmorillonite. During preparation, an oil phase and an aqueous phase are prepared separately. Sodium alginate is added to the aqueous phase, and then the oil phase is added to the aqueous phase. After homogenization, lithium distearate dimethylammonium montmorillonite is added, followed by homogenization and defoaming. This lip mask composition has a novel user experience, a noticeable immediate visual effect (the appearance of the lip mask can be observed to change), and a long-lasting effect. After the film is formed, it can be peeled off completely, which can reduce the evaporation of skin moisture and help the moisturizers in the formula to gently penetrate into the stratum corneum without irritating the skin barrier. After peeling off the film, old keratin on the lips is removed, leaving the lips feeling refreshed, breathable, and non-sticky. It immediately improves dry lips and brightens lip color after use.
