By studying effects of main ingredients (cetyl alcohol, conditioning agents and rheological additives), the suitable content of them were determinated for optimizing the feeling. Besides, during execution, Belsil® ADM 331 was added at 0,4% (w/w) to enhance the feel of use, especially in wet feel. The shelf-life of target product was predicted about one year by the comom test in laboratory. After trial period on consumers, the appearance and the feel in use of research product was evaluate at good (4/5) grade with high accuracy level.
Over 70% of volunteers (22/30) were willing to pay from 50,000 to 70,000 VND for 1bottle / 250g. Besides, the raw material charge for 1 kg product was only 32,000 VND. It was found that those products came with reasonable and competitive prices. In conclusion, the research product is available for commercial purpose.
ix do an PREAMBLE Hair contributes significantly to the visual image of both males and females of all ages. Hairstyle, apparently, hides face limitations away, creates a highlight for good looks and reveals personnel individuality. In general, traditional girl favorably chooses classic hairstyle such as ponytail, bun, and shoulder-length. Styling hair by a pigtail or bunches for the childlike concept.
Long hair combined with a mild perm is the image of a sweet girl. Dyeing hair is very suitable for the strong personality and short hair is the best choice for the self-motivated. Healthy hair is a key factor influencing the beauty of hair. It is reasonable to accept that the weak hair isn‟t willing to build-up on hair.
The non-glossy hair seems to look like dirty and the arid hair being the same as bamboo root make a bad appearance. The causes of hair damaged are mechanical traumas, chemical treatments, and environmental factors. Therefore, hair care products, especially hair conditioner, are essential demand for the fascinating hair. I have a passion along with a curiosity in cosmetics and get a suggestion about the hair care field by my supervisor, Assoc.
Le TH Nhan. In addition, research and development (R&D) is an aspect of my future job. For these reasons, I research on topic "Improving the sensory effects of hair conditioners with Belsil® ADM 331". x do an CHAPTER 1: INTRODUCTION Hair provides protective, sensory, and sexual attractiveness functions.
All visible major body surfaces are covered with some type of hair, providing endless opportunities for cosmetic adornment. Nowadays, beautiful hair is indeed an important part of personal beauty. In the aesthetic term, keeping hair in good conditions helps a person feeling comfortable and confident. Changing hair into the desired color and a fashionable style can improve attractiveness [1].
It is noticeable that, before styling, you should pay attention to make a daily routine to take care of your hair because healthy hair is the important factor influencing the beauty of hair. For instance, the non-glossy hair seems to look dirty and the arid hair being the same as the bamboo root makes a bad appearance. These are some signs of damaged hair. The causes of hair damaged are mechanical traumas, chemical treatments, and environmental factors.
Moreover, hair is non-living material, therefore, hair care products, especially hair conditioners, are an essential demand for fascinating hair. It is one of the key answers for how to get healthy hair. Hair physiology Hair is a protein filament that grows from follicles found in the dermis. Hair follicle extends from the surface of the skin through the stratum corneum and the epidermis into the dermis.
Hair follicle is responsible for the formation and production of hair fiber [2], in other words, impacts directly to almost the physiological of hair. All of them are richly endowed with sensory receptors and have a highly-developed sense of touch [3]. The difference in shape of this organ, which is specified by gene, makes the diversity of natural hairstyle. 1 do an Figure 1.
1 The anatomy of human hair (Source: Macrovector PTE Ltd) The sebaceous gland located at the upper part of the follicle, being responsible for secreting sebum, a natural hair conditioners including free fatty acid and neutral fast, to lubricates and protects the scalp and hair [2]. Sebum is produced in increased amounts after puberty in males and females and abundantly coats the hair shaft in youth. With advancing age, sebum production declines in the female with a less significant decrease in males, therefore makes some differences in hair physiology at the elderly age between men and women. Hair is nonliving material; however it is within a cycle of constant renewal and shedding.
Unlike other organs where limited cellular renewal can occur, hair growth occurs at the amazing rate of 0.35mm/day [4] allowing the removal of old, damaged hair that is readily replaced with new regrowth. Hair is the only body structure that is completely renewable as long as the follicle remains a functioning unit. Hair growth is in a cyclic basis with absolute accuracy periods, including three common stages below. The growth period, known as anagen, lasts approximately 1000 days.
Hair is only produced in this stage so the duration of anagen determines the maximum length and the thickness that the hair can be grown to. It grows more quickly in summer than in 2 do an winter, at night than by day, and women‟s hair grows more quickly than men‟s. Moreover, there are many factors that also influence the length of the anagen phase, including genetics, nutrition, age and overall health [4].
