This study aims to 1) Product development of hand washing liquid soap smell Thai perfume 2) Physical and chemical properties Product of liquid soap hand wash smell Thai perfume and3) Consumer satisfaction survey on smell Thai perfume hand washing liquid soap products A questionnaire on consumers behaviors related to OTOP products was conducted. And smell test to choose the most acceptable smell. With 30 guests There were 3 levels of odor in liquid soap: 0.2 percent 0.5 percent and 0.8 percent. With 5 experts Experimental plot design RCBD (Randomized Complete Block Design) The 9-tailed test was used (9–point Hedonic scale) with sensory tests and use percentage statistics. With Acceptance and satisfaction test and physical properties viscosity color and chemical analysis of alkalinity were analyzed. 100 people were tested for satisfaction. The results indicate that most consumers are mostly female. Think 73.3 percentage. The behavior of consumers in using smell Thai perfume. Liking smell Thai perfume flower scent it thinks 90 percentages. bottle filling 100 cc it think53.3 percentages. And the smell that is most liked is the smell of Pip flowers. The average level of smell is very similar. At the rate of replacement liquid soap to smell the smell Thai perfume. The highest score was the formula 2 /0.5 percentage. Physical Properties of Viscosity stability at 527.4 Point Centrino it is liquid stability on surface very gool. Color values have average brightness (L*) green values (a*) and blue values (b*) is equal to 16.47. The liquid soap is greenish yellow. Chemical qualities in acidity it was found that the pH value was 5-8 (6.20 ± 0.01). Followed by product standards community. Consumers are satisfied with liquid soap products with smell Thai perfume like 50.1 percent in terms of color intensity like 35 percent Is the sole of liquid soap like 62 percent Medium scent like 44 percent Medium Concentration like 69 percent finally not irritating to the skin like 98 percent.

การวิจัยฉบับนี้ได้กล่าวถึงการลดระยะเวลาการทำแม่พิมพ์ยางซิลิโคนโดยเร่งความแข็งด้วยอุณหภูมิต่ำ เนื่องจากแม่พิมพ์ยางซิลิโคนใส สามารถเก็บรายละเอียดของชิ้นงานได้ดีและสามารถมองเห็นชิ้นงานด้านในได้แต่แม่พิมพ์ยางซิลิโคนใสใช้เวลาในการแข็งตัวนาน จึงได้ศึกษาและทำการทดลองนำเอาอุณหภูมิความเย็นเข้ามาช่วยในการเร่งการแข็งตัวของซิลิโคนใสโดกำหนดอุณหภูมิเป็น 3 อุณหภูมิ ประกอบด้วย 10 5 0 องศาเซลเซียล แต่อุณหภูมิแบ่งเป็น 3 ช่วงเวลา ประกอบด้วย 2 3 4 ชั่วโมง จึงทำการการทดลองขั้นต่อไป จากการทดลองโครงการลดระยะเวลาการทำแม่พิมพ์ยางซิลิโคนใสโดยเร่งความแข็งด้วยอุณหภูมิต่ำเพื่อหาอุณหภูมิและช่วงระยะเวลาที่เหมาะสมในการเร่งความแข็งของซิลิโคนใส พบว่าที่อุณหภูมิ 5 องศาเซลเซียล ช่วงระยะเวลา 3 ชั่วโมงมีค่าความแข็งใกล้เคียงกับมาตรฐานและมีความเหมาะสมที่สุด เนื่องจากผลการทดลองพบว่าอุณหภูมิและระยะเวลาที่เหมาะสมที่สุดนั้นสามารถลดระยะเวลาการแข็งตัวของซิลิโคนใสได้ 6 ชั่งโมงและมีประสิทธิภาพใกล้เคียงกับชิ้นงานมาตรฐาน

Development of Liquid Soap with Banana Peel Pulp. We have studied the process of developing a recipe and product processing pulp peel bananas: banana peel and pulp of 3levels which take data from a survey of consumer behavior to suit the application. Andhave studied the sensory quality of the products liquid soap mixed pulp banana peel on 3 levels 5: 48.6 10 43.6 and 15 38.6% indicated that test scores give the formula 2 (20:10). in terms of color homogeneity. And texture (thick) overall. Levels like moderately to like verymuch. In terms of cleansing and smell no different at a statistically significant (p> 0.05) werethen tested for quality physical found that Liquid Soap with Banana Peel Pulp Formula 10:43.6% of the color. lightness (L *) was 59.6 ± 0.01 redness (a *) was -0.42 ± 0.01 andyellowness (b *) were 1.31 ± 0.01 which liquid soap is opaque. Because of the banana pulp is mixed in liquid viscosity in the 2584 Point Centrino bubble volume 370 ml and the water chemistry. The pH value of 6.52 ± 00.1 in the pH range 5-8 Thai Community Product Standard. Microbiological quality The shelf life of the product liquid membrane banana: banana peel and pulp. Store in a sealed jar per piece. Kept at room temperature The products were analyzed analyzed microbiological quality. Therefore the total plate count And yeast and mold By sampling every 1 week for a period of 8 weeks the total plate count<10 (CFU / g) Clostridium spp. Was not found Staphylococcus aureus None Streptococcusspp. Did not find Salmonella spp. Did not find Pseudomonas aeruginosa is found Coliform bacteria less. 3 MPN per gram Escherichai coli has been found safe for consumption. The resort complying with (TCPS. 95/2552) is to be a Thai Community Product Standard LiquidSoap of bacteria must be less than 1000 colonies per gram. Or cubic centimeters Meet ThaiCommunity Product Standard Liquid Soap education acceptable to the liquid membranebanana: banana peel and pulp were found to have a moderate satisfaction. Irritation andfeeling 100 percent.

This paper presents a mathematical modelling for design the control system of a liquid. The system are consists of one and two tanks of a liquid. To confirm the achieved mathematical modelling is used to design P PI PD and PID controller in the frequency domain. The experimental results are indicated as the following. An one tank of a liquid controlling The controller can be control the liquid level to set point with in 100s. In the case of a disturbance occurs in the system it is perform by drain a liquid. As same as the controller it can be control the liquid level into the steady state. In the part of the liquid control this is the interaction between two tanks. The experimental results of the system operation the controller can be control the liquid into the set point both occur disturbance and without disturbance respectively

This research aims to develop Thai herbal formulas for household cleaning products and reduce the use of chemicals by using kaffir lime herbs to extract essential oils by using a method of squeezing from the bark. The result is a dark green essential oil with a pleasant aroma when mixed with liquid hand soap and natural residues such as water extracted from silkworm cocoons to add moisture and lye to remove it. Reduce the use of chemical flavoring agents the use of coloring chemicals the use of moisturizing agents and the use of degreasers. In this research the formula for hand washing liquid soap using 80 ml. of essential oil from kaffir lime peel is the right amount resulting in liquid hand soap with a pH value of 7.3 which is the value that is in the standard for mixed liquid soap products. TIS 1403-2551 can inhibit the bacteria Staphylococcus aureus (S.aureus) a bacterium that can cause diarrhea in humans.
