코스메슈티컬 화장품의 인지적·감성적 경험이 브랜드 충성도에 미치는 영향
송마리아,전해정 대한미용학회 2019 대한미용학회지 Vol.15 No.3
Cosmeceutical Cosmetics market by conducting a study to better understand the potential impact of cognitive and emotional factors—attributes that are directly experienced and felt by the brand—on brand loyalty. Research has shown significant differences in cognitive experience and brand loyalty depending on general characteristics. Emotional experience has been shown to have a greater impact on brand loyalty than cognitive experience. Therefore, there is a need for e-marketing strategies to recognize both cognitive and emotional experiences for Cosmeceutical cosmetics. In particular, for emotional experience, it is necessary to induce special sensibility through the color of cosmetics containers or develop novel containers with other appealing atributes. In addition, it is necessary to study and appropriately adapt marketing strategies (eg, design of stores including interior and rest areas) through colorsensitive collaboration, and building storytelling images that can stimulate customer sentiments.
Polyquaternium-10 / Sodium Cocoyl Alaninate 콤플렉스 용액의 상거동 및 유변학적 특성
송마리아,진병석 한국고분자학회 2023 폴리머 Vol.47 No.6
The complex solutions formed between polyquaternium-10 (PQ-10), a cationic polymer, and sodium cocoyl alaninate (SCoA), an anionic surfactant, were in three different stages of dissolved state depending on the mixing ratio, and the phase behavior of complex solutions for each stage was examined. The viscosity and modulus changes of the PQ-10 polymer solution and the PQ-10/SCoA complex solution were compared, and a relaxation time was calculated. In addition, the thixotropic behavior of the complex solution forming the network was examined through shear stressstrain rate measurement, and the flow behavior index value was obtained by applying the Herschel – Bulkley fluid model equation. Finally, the C.M.C value of SCoA in pure water and the C.A.C value of SCoA in PQ-10 solution were compared, and the effect of the combination of PQ-10 and SCoA on the wettability of water was investigated.
혼합물 실험 계획법을 활용한 세정용 계면활성제 혼합물 조성의 최적화
송마리아 ( Maria Song ),진병석 ( Byung Suk Jin ) 한국공업화학회 2021 공업화학 Vol.32 No.5
최고 품질의 클렌징 제품 개발을 위해서 계면활성제 혼합물 조성의 최적화를 시도하였다. 사전실험을 통해 세정력, 기포형성력, 오염률에서 각각 우수한 특성을 나타내는 계면활성제 3종 sodium cocoyl alaninate (SCoA), cocamidopropyl betaine (CPB), decyl glucoside (DG)을 선정하였다. 계면활성제 혼합물의 심플렉스 중심 설계 배열에 따른 실험을 수행하고, 실험에서 얻어진 데이터를 가지고 회귀분석을 실시하였다. 통계적으로 유의미한 반응 표면 모델식을 구하고, 세 개의 반응변수의 동시 최적화 과정을 통해 계면활성제 혼합물의 최적 조성은 SCoA (0.22), CPB (0.78), DG (0.00)으로 구해졌다. The main goal of this study was to find an optimal surfactant mixture composition for the development of the best performing cleansing products. Three different surfactants including sodium cocoyl alaninate (SCoA), cocamidopropyl betaine (CPB), and decyl glucoside (DG) were selected, which showed excellent properties in detergency, foaming height, and contamination rate through preliminary experiments. The experiments by simplex centroid design matrix for surfactant mixtures were performed, and the regression analysis was conducted with the experimental data. Surface response model equations, which is statistically significant (p < 0.05), were obtained. The optimal composition of the surfactant mixture was also determined as SCoA (0.22), CPB (0.78), and DG(0.00) from simultaneous optimization of three response variables.
수크로스 스테아레이트의 유화력 및 가용화력 향상을 위한혼합물 조성 최적화
배종환,송마리아,진병석 한국응용과학기술학회 2024 한국응용과학기술학회지 Vol.41 No.2
본 연구에서는 수크로스 스테아레이트(SS)의 유화력과 가용화력을 좀 더 향상시키기 위해, sodium deoxycholate (SDOC)와 PEG-40 hydrogenated castor oil (HCO)와의 혼합 조성물을 구성하였다. 혼합물의 최적 조성을 구하기 위해 혼합물 실험 계획법을 도입하여 실험을 진행하고, 실험에서 얻은 데이터를 회귀 분석하여 혼합물 조성의 변화가 혼합물의 특성에 미치는 영향을 살펴보았다. SS에 SDOC만을첨가했을 때 코코넛 오일에 대한 유화력이 가장 향상되고, HCO만을 첨가했을 때는 가용화력이 가장 향상된 반면, 에스테르 오일인 cetyl ethylhexanoate (CEH)에 대한 유화력은 SDOC와 HCO를 함께 첨가했을때 가장 크게 향상됨을 알 수 있었다. 코코넛 오일 및 CEH 각각에 대한 유화력과 가용화력, 3개의 특성치에 대한 동시 최적화를 실시한 결과, 최적의 계면활성제 혼합 조성은 SS 0.7939, SDOC 0.0586, HCO 0.1475로 구해졌다. In this study, we enhanced the emulsifying power and solubilization of sucrose stearate (SS) by creating mixtures with sodium deoxycholate (SDOC) and PEG-40 hydrogenated castor oil (HCO). We employed the design of mixture experiments (DOME) methodology to identify the optimal composition of the mixture, and the impact of varying the mixture composition on its characteristics was examined through regression analysis of the experimental data. It was revealed that the emulsifying power for coconut oil was most improved when only SDOC was added to SS, and solubilization was most improved when only HCO was added, while the emulsifying power for cetyl ethylhexanoate (CEH) was most significantly improved when SDOC and HCO were added together. As a result of simultaneous optimization of three characteristics, emulsifying power for each of coconut oil and CEH, and solubilization, the optimal surfactant mixture composition was determined as SS 0.7939, SDOC 0.0586, and HCO 0.1475.
