Southeast Science and Technology established a sensory evaluation system for the cosmetics industry, X-Rite Colorimeter & Boller Viscometer / Rheometer, Han Shu, Xiang
Yibencao, Baique Ling, Winona and other brands as well as some raw material suppliers and factories have established or are in the process of establishing a sensory evaluation system.
See its trend.
What is a sensory evaluation?
According to Ma Ping, the manager of Essence and Efficacy Evaluation, the so-called sensory evaluation refers to the feeling of using the senses ( qi, taste, touch,
Temperature, pain, etc. ) evaluate and judge cosmetics, and obtain them through the application of scientific and accurate analytical methods.
The results are reproducible and statistical.
Â
The sensory evaluation began in the 1940s and has not been in the development process for less than one hundred years.
A variety of consumer goods industries, including cosmetics, personal care products, household products, flavors and fragrances, tobacco, textiles and so on.
China's sensory evaluation of cosmetics is still in its infancy, and no unified regulations have been made on the sensory evaluation of cosmetics.
Many companies have not yet established a sensory evaluation system.
2014  year  3  In the month, Ou Shiman introduced the sensory evaluation system, trained and established a team of experts, 2015  Guangzhou  PCHi  forum,
Ou Shiman introduced the sensory evaluation and reported it.  BB\CC  Frost sensory evaluation results, 2015  year  6  From the beginning of the month, Ou Shiman and
Third-party cooperation to improve the evaluation system.
How do companies build their own sensory evaluation systems ?
Sensory evaluation can be carried out for all products such as liquid, cream, make-up, washing, personal care, hair products, etc.
The evaluation dimension is not exactly the same, such as the sensory evaluation of the cream, including the appearance, aroma, texture during touch, provocation, smearing
The sense of absorption and sensation of absorption, skin softness after use, moistness and moisturization.
Ma Ping, the manager of Essence's sensory and efficacy evaluation, talked about sharing. Generally speaking, the internal sensory evaluation system of the company includes the following
Several aspects: personnel, equipment, laboratories, sensory evaluation systems and annual operating costs.
device:
Basic equipment: necessary temperature control facilities, color temperature control, ventilation equipment, lighting and cleaning equipment, etc. Â Container, balance, constant
Thermostat, refrigerator, etc .;
The instrument configuration is as follows:
a) Â Rheometer: An instrument used to determine the rheological properties of skin care products such as lotions.
b)  Color difference meter: mainly based on  CIE  Color space  Lab , Lch  Principle, the measurement shows the color difference between the sample and the sample to be measured △ E
And △ Lab  value.
c) Â Sensory intelligent analysis system: the electronic nose / electronic tongue commonly used , mainly composed of interactive sensitive sensor arrays and signal acquisition
A modern qualitative and quantitative analysis instrument consisting of road and data processing methods based on pattern recognition. Generally used in skin care products
In the evaluation of the fragrance.
d) Â GS-MS Â Component analyzer: an organic substance that is easily vaporized by gasification or derivatization after gasification or mass spectrometry,
After separating the components by gas chromatography, qualitative and quantitative determination was carried out. It is generally used in the evaluation of fragrances in skin care products.
e) Â Texture Analyzer: Detects the elasticity, resilience, adhesion, consistency, tensile strength and ductility of different skin care products.
f) Â Data acquisition electronic devices such as ipad/ computer.
total alkalinity: prevent fluctuation in pH levels
Free Chlorine: Chlorine may be present in tap water. It is harmful to fish, damaging their gills and skin, and must not be introduced to the aquarium
pH: pH value between 6.5 and 8.5 will be tolerated by most freshwater fish species
Bromine: Keep your bromine levels on point and effective
Total hardness: prevent corrosion and scaling in your pool or spa
