Abstract

The purpose of this study was to examine the correlation between physical properties of dried coacervate films and dry feel for shampoo composition. Simple shampoo compositions were made of two different cationic charge density polymers in the same surfactant compositions. The simple shampoo compositions were diluted with distilled water to make coacervate. Formed coacervate was collected by centrifuge (3,000 rpm, 30 min). Coacervate was coated on the glass plates and dried in drying oven (for 1 h, $50^{\circ}C$) to make the thin film. We carried out an experiment on measurement of contact angle, moisture loss ratio and SEM image analysis of the dried coacervate film. Dry feelings of the shampoos were evaluated by panel using hair tresses. Results show that the properties of dried coacervate films affect the dry feel of the after shampooing.

본 연구는 건조된 코아세르베이트 필름의 물리적 특성이 샴푸 건조 후 모발 사용감에 미치는 상관관계를 조사하기 위하여 실시하였다. 단순 샴푸 조성물은 동일한 조성의 계면활성제에 양이온 전하 밀도가 서로 다른 두 종류의 양이온 폴리머를 사용하여 제조하였다. 이 단순 조성물을 물에 희석하여 코아세르베이트(Coacervate)를 형성되도록 하였고, 3000 rpm, 30 min 조건으로 원심 분리하여 형성된 코아세르베이트를 얻었다. 얻어진 코아세르베이트를 유리판 위에 균일한 두께로 도포하고 $50^{\circ}C$ 건조기에서 1 h 건조하여 코아세르베이트 필름을 얻었다. 이렇게 얻어진 코아세르베이트 필름의 접촉각과 코아세르베이트의 SEM 이미지 조사를 수행하였고, 코아세르베이트의 수분 보유량과 수분 유지력을 동시에 조사하였다. 샴푸 후 건조된 모발의 부드러움과 보습감은 모발타래를 이용하여 전문 미용 패널이 평가를 수행하였다. 본 실험결과 건조된 코아세르베이트 필름의 특성이 샴푸 후 건조된 모발의 부드러움 및 보습감에 영향을 주는 것으로 확인되었다.
