AI Technical Summary
In existing facial cleansing products, bentonite clay tends to agglomerate in aqueous solutions, leading to sedimentation. Furthermore, when used alone, bentonite clay cannot continuously absorb oil during rinsing, thus failing to effectively control oil production. Additionally, the high content of surfactants can cause skin tightness and exacerbate acne-prone skin problems in the long term.
A bentonite composition was prepared by dispersing bentonite in an organic solvent, adding hot spring water, removing the organic solvent, mixing it with hydrolyzed starch, and heating and stirring. The synergistic effect of bentonite and hydrolyzed starch was utilized to improve dispersibility and stability, thus preparing a bentonite composition with cleaning and oil-controlling effects.
It achieves good dispersibility and stability of bentonite in aqueous solutions, has continuous oil control capabilities, improves the skin feel, avoids skin tightness caused by surfactants, and reduces the long-term aggravation of acne.
