Development and efficacy evaluation of hair care formulations containing vegetable oils and silicone

Abstract

Considering the growing interest and consumption of hair care products, given that Brazil is the third world market for personal hygiene, perfumery and cosmetics and the second world market for hair cosmetics, 2 the Research and Development of innovative and effective products is of fundamental importance. Thus, there is a growing interest in researches that evaluates the hair damage caused by environment and chemical treatments, as well as the development of formulations that meets the consumer's needs. 3,4 Previous studies of our research group have shown that hair care is of prime importance for the quality of life and well-being of women, since hair plays a significant role in women's body image. 1 Several ingredients have been used for hair cosmetics, such as proteins, amino acids, vitamins, conditioning agents, sunscreens, plant extracts and mainly silicones, due to their low cost. Silicones are used for hair treatment due to its properties, which allows it to deposit on the surface, forming a uniform film, 5 giving the feeling of conditioning in the fiber. However, the use of silicones promotes only a superficial treatment of the fiber. Thus, substances of natural origin such as vegetable oils are now being explored by the cosmetic market. Vegetable oils are natural compounds, derived from oleaginous plants, which presents several benefits to the human body, skin and hair. The vegetable oils are

Development of hair care formulations based on natural ingredients

“…The results showed statistical differences between C and H5 (P < 0.0009), H3 (P < 0.02) and H6 (P < 0.04) adding a higher concentration of antistatic agents to the formulation because it decreases the combing force. 9,15 Tensile Test The results showed that different treatments were able to increase the hair fiber resistance when compared to the control since the maximum force required to break the hair fiber was higher ( Figure 7). Hair samples treated with shampoo added with hydrolyzed rice peptides, regardless of the conditioner used, had a significant difference (P < 0.05) in the force required to break the hair fiber when compared to the control.…”

“…19 However, with this result, it was possible to observe the action of this active substance on the internal structure of the capillary fiber (cortex). 9 Hair Gloss Analysis Figure 8 showed the results of hair gloss analysis. There was a considerable increase in brightness in the H4.…”

“…The analysis of sensory properties, rheology behavior, and texture profile are important to understand the behavior of ingredients in the formulation and its acceptability by the consumer. 1,8,9 In addition, studies of effectiveness in hair fiber are essential to evaluate the performance of hair care formulations and consumer acceptability. Tensile and combability tests can be performed using the TA XT Plus ® Texturometer (Stable Micro Systems) on the hair fibers.…”

“…Noninvasive image analysis using Skin Glossymeter GL 200 determines hair brightness through the principle of reflectance. 1,8,9 In this context, the aim of this study was to develop and evaluate the stability, physical-mechanical and sensorial properties of hair care formulations based on natural ingredients as well as the efficacy of these formulations in the improvement of mechanical properties and gloss of hair.…”

Transparent silicone‐free shampoo containing proteins with strong hair conditioning properties

“…As an ideal oil conditioner for hair, silicone oil has been widely used in hair products due its outstanding properties, such as stable chemical properties [10], low surface tension, non-toxicity, smoothness, water retention, and low price. In addition, the silicone oil and cationic polymers in the shampoo will be absorbed and accumulated on the hair surface to form a protective film and further adhere to the crevices of the hair scales during the hair care process.…”
