The preparation of peel-off facial mask composed of water and oil phases was systematically studied.When facial mask was used,water and oil phases were mixed in a certain proportion and used on the face.After a certain period of time,the film could be formed and removed.The effects of the dosage of sodium alginate on the viscosity of the peel-off facial mask and the dosage of anhydrous calcium sulfate on the film-forming time of the peel-off facial mask were investigated;The effects of diatomite,kaolin and perlite on the film toughness of peel-off facial mask were compared;The effects of the amount of sodium chloride and PEG-75 on the moisture content of the peel-off facial mask were investigated.The results showed that when the dosage of sodium alginate was 2.33%,peel-off facial mask had a suitable viscosity;the film-forming time will be shorter when the amount of anhydrous calcium sulfate is higher;Diatomaceous earth makes the film of peel-off facial mask more flexible;Too much sodium chloride and PEG-75 will cause water leakage during the use of facial mask,while too little sodium chloride and PEG-75 will make consumer feel dry and insufficient moisturizing.
