The global laundry detergents market in 2021 was valued at nearly $121 billion, with consumers being reported as heightening their search for hygienic products capable of fighting viruses. Therefore, the researchers undertook a study to determine how product innovation (PI), product quality (PQ), and product attitude (PA) effects Thai consumers' satisfaction (CS) with their purchase of laundry detergent and fabric softener. After the questionnaire's validity and reliability confirmation, the authors used multi-stage random sampling by region and province in January and February 2022 to collect 520 questionnaires. LISREL 9.10 was used in the CFA and SEM analysis of the six hypotheses, which were determined to be supported. The results showed that all three causal variables positively influenced CS, with a total effect (TE) R² value = 87%. Also, latent variable total effect (TE) values showed that PI was strongest (0.93), then PQ (0.56), and finally, PA (0.54). Therefore, consumer satisfaction is essential in a firm's ongoing development and sustainability in a highly competitive, globalized world. Organizations must develop competitive strategies that adjust to consumer needs. Management must monitor online and social media sources where product reviews are given and adjust their strategies accordingly.

The acute oral and genetic toxicity of ASCO EAQ80 was established in this study. ASCO EAQ80, a novel cationic surfactant produced by Aekyung Speciality Chemicals Co. LTD. is currently commercialized as a clear fabric softener. In acute oral toxicity study, the 50% lethal dose $(LD_{50})$ of ASCO EAQ80 was determined to be higher than 5000 mg/kg and this product could be classified as Category 5 or Unclassified by Globally Harmonized Classification System. Also, to establish the gene-toxicity of ASCO EAQ80, we performed bacterial reversion assay against Salmonella typhimurium TA98, TA100, TA1535, TA1537, Escherichia coli WP2uvrA, and in vitro chromosomal aberration assay against Chinese hamster lung cells in the presence and absence of S-9 metabolic activation system. From these experiments, ASCO EAQ80 revealed nonmutagenic potential in S. typhimurium TA98, TA100, TA1535, TA1537, and Escherichia coli WP2uvrA both in the absence and presence of metabolic activation system. No clastogenicity of ASCO EAQ80 was observed in chromosomal aberration assay in vitro.

Most silk fabrics are produced only after the degumming process to make the best use of the properties and have restricted silk processing that do not hinder their performance. However, considering the highly increased preference for natural fibers and the shortage of raw silk, high-quality upgraded silk product functions are required by the development of a processing technology and a good design. This study analyzes the changes with the samples by the functional finish such as softening finishing, wash and wear, tannin weighting by measuring the objective hand of scoured silk and three finished ones using KES-FB. As a result, the change of objective hand of finished silk fabrics that improves functionality was analyzed and compared. The increase of KOSHI after the finish became stiffer show that the silk fabric samples are appropriate for summertime clothes with the retention of a certain clothing climate for the body. The stiffness of finished fabrics for the normal had a closer relationship with the density of fabrics than the type of finishing. The samples (after the softening finishes) maintain better elasticity according to the properties of the softener and the finishing agent. Although the specimens of this study were thin fabrics, their elasticity against compression increased after the softening finishes and became softer than degummed silk. The surface properties of georgette were changed by all types of finishing.

Triethanolamine-type cationic surfactants were synthesized and their applications were established. The production of mono-, di-, and tri-TEA-EQ (triethanol-amine-esterquater) were dependent on the molar ratio of fatty acid and triethanolamine under the controlled reaction temperature. The structures were elucidated by $H^{1}$ NMR. Long-term stability was dependent on the amount of mono- and tri-TEA-EQ. When the amount of mono-TEA-EQ was increased, long-term stability was increased. However, the more tri-TEA-EQ made long-term stability decreased. Softening was dependent on the amount of saturated fatty acid, and re-wettability was counted on the amount of unsaturated fatty acid. Softening was measured by the method of sense estimation e.g. touching to home-towel. Absorption was determined to calculate the height of water on a towel after treatment.

This study was performed to develop face towel fabrics that reflect consumer's tactile preferences. Three different kinds of pile fiber (100% cotton, 50% cotton/50% bamboo, 100% bamboo) of the towel fabrics were selected for the test. The towels were laundered one, five and 10 times repeatedly in a normal washing condition, and fabric softeners were applied to the towels that were laundered 10 times. The flexibility and absorbency (absorption rate and water absorptivity) were evaluated by laundering times of the face towels. Male and female university students evaluated their subjective sensations of the face towels. The flexibility of towel fabrics showed no significant difference according to type of pile fiber or laundering time. The absorbency of the towels was significantly different according to the type of pile fiber and laundering time. The absorption rate was higher in 100% bamboo fiber, and water absorptivity was higher for cotton fibers. There were no significant differences in subjective sensation according to the type of pile fiber of towels before laundering. As the frequency of laundering increased, the tactile preference for the towel slightly decreased. The 100% bamboo towel was rated the most comfortable among the three kinds of towels. The tactile preference for the towels was influenced by smoothness, fabric softness, and softener treatment, in that order.

In this study, interfacial properties were measured for imidazoline type cationic surfactant system which has been widely used as a fabric softener, a dispersant, an anti-static agent, a bleach activator, and an emulsifier. The CMC of imidazoline surfactant was near $6{\times}10^{-5}mol/L$ and the surface tension at CMC was about 32 mN/m. It was found that surface tension was not affected by surfactant concentration but decreased with an increase in pH. The interfacial tension between 1 wt% aqueous solution and n-dodecane was shown to be about 0.01 mN/m and equilibration time was not affected by pH. Phase behavior experiment in a binary aqueous surfactant system showed that only micellar solution of $L_1$ phase was found under conditions of temperature and pH investigated during this study. Only a two-phase region consisting of lower-phase microemulsion in equilibrium with excess oil phase existed under the same conditions, when oil was added to the binary surfactant system. The foam stability measured with 1 wt% surfactant solution increased with pH, which is consistent with surface tension measurement result. QCM(quartz crystal microbalance) measurement showed that surfactant adsorption increased with surfactant concentration but decreased with pH. According to the friction measurement, best fabric softening effect by imidazoline surfactant system was found under alkali conditions.
