The cosmetic cleansing paste is designed for skin brightening and includes a combination of hydroxy acids, niacinamide, a bio-based glycolipid surfactant, thickeners, clay, and a solvent primarily consisting of water. Its pH level ranges from 4.4 to 5.0, making it suitable for daily use as a cleanser, facial mask, or spot treatment. The formulation aims to provide gentle exfoliation, enhance skin brightness, and even out skin tone.
The composition features a blend of alpha-hydroxy, beta-hydroxy, and poly-hydroxy acids, which contribute to its exfoliating properties. Niacinamide, known for its skin brightening effects, is included to enhance overall complexion. The bio-based glycolipid surfactant, such as rhamnolipid, ensures effective cleansing while maintaining the paste's stability and texture.
The cleansing paste is carefully formulated to maintain a stable, off-white, paste-like texture that does not drip. Its viscosity is maintained between 30,000 cP and 300,000 cP, even after storage at elevated temperatures. Key ingredients include lactic acid, salicylic acid, gluconolactone, xanthan gum, and kaolin clay, each contributing to the product's efficacy and texture.
This versatile product can be applied as a spot treatment, cleanser, or mask. When used, it provides gentle exfoliation and helps in reducing uneven skin tone and enhancing brightness. The formulation is designed to be easily spreadable and retains its structure during application and removal, ensuring a user-friendly experience.
The composition may also include additives like cetyl alcohol, sodium hydroxide, and various glycols to enhance performance and stability. The paste is designed to minimize niacin production, a potential degradation product of niacinamide, ensuring that the active ingredients remain effective throughout the product's shelf life.
