住化分析センター List of Products and Services

The Sumika Analytical Center, Inc. comprehensively examines many components contained in samples using GC×GC-TOFMS. It enables ultra-high separation analysis through two-dimensional chromatographic separation and precise mass measurement, allowing for the comprehensive detection of components that are difficult to separate with conventional GC-MS, and high-accuracy qualitative analysis through precise mass measurement. Please try it for comparative analysis of samples or analysis of aroma components. 【Features】 ■ Ultra-high separation analysis is possible through two-dimensional chromatographic separation and precise mass measurement ■ Comprehensive detection of components that are difficult to separate with conventional GC-MS through two-dimensional chromatographic separation ■ High-accuracy qualitative analysis is possible through precise mass measurement *For more details, please refer to the PDF materials or feel free to contact us.

We offer analysis of body odor components. There are various odor components that cause body odor, and technology for highly sensitive measurement is required. Please utilize this for the development of functional cosmetics and for confirming deodorant effects. [Sampling Examples] - Sweat, scalp, etc.: Wiping and collection - General body odor: Adsorption onto clothing *For more details, please download the PDF or feel free to contact us.

Our company uses statistical analysis of data to derive valuable information that connects the analysis results to the characteristics of our products. As a case study (analysis of factors affecting fragrance changes), we heated perfume at 100°C and conducted sensory evaluations of the fragrance, quantitative analysis of organic components (GC-FID), and qualitative analysis (GC-MS) at 13 time points (0, 2, 3, 4, 6, 8, 9, 14, 16, 18, 20, 22, and 24 hours). Through principal component analysis, we were able to analyze the main contributing components to fragrance changes from a complex array of information. [Example of Principal Component Analysis] - A total of 2,548 data points (13 samples × 196 peak quantitative values) were analyzed and represented in two dimensions. - The meaning of the two-dimensional axes (PC1 vs. PC2) was interpreted in relation to the fragrance. - Components influencing axis formation were explored using a contribution rate plot (not included). *For more details, please download the PDF or feel free to contact us.*

Our company conducts sensory evaluation through two approaches: psychological and physical, to support product development. As the importance of manufacturing that resonates with human sensibilities increases, there is growing attention on the design and development of new products and services that possess "sensory value," which can positively change people's feelings and perceptions, in addition to the traditional values of functionality, performance, and reliability. For example, when developing cosmetics that have a "luxurious appearance," it is possible to maximize sensory value by extracting and evaluating the impression elements (such as opulence and elegance) and physical elements (such as color, shape, and texture) that constitute the target user's sense of "luxury." *For more details, please download the PDF or feel free to contact us.

At our company, we qualitatively and quantitatively analyze surfactants, which can be said to be the elements that determine the quality of cosmetics, using various methods for emulsification, dispersion, stabilization, and control of usability. Please feel free to contact us if you have any requests. 【Overview】 ■ Qualitative analysis: MALDI-SpiralTOFMS × KMD plot analysis ■ Quantitative analysis: LC-MS/MS *For more details, please download the PDF or feel free to contact us.

Our company evaluates hair damage improvement using a "tactile benchmark." We propose the use of "quantified and visualized sensations" through instrumental analysis as evidence for detecting differences between products and for sensory evaluations. We can evaluate a wide range of products, including hair care, skin care, and cosmetics, all of which are "touched by fingertips." [Features] ■ By using a tactile sensor, it is possible to measure the physical properties that govern texture under conditions close to human touch. ■ Since a vacuum environment is not required during measurement, it allows for the observation of hair surface under conditions similar to actual usage. *For more details, please download the PDF or feel free to contact us.
