Micellar shampoos as a new form of cosmetics for washing hair

 

 

 


Key words:

micellar shampoos, surface activity, micelles, physico-chemical properties.

Summary

Shampoo manufacturers use the term “micellar shampoos” to refer to mildly acting cosmetics, dedicated to people with delicate, brittle, thin hair and skin prone to irritation. The formulation solution proposed by the manufacturers is designed to combine mild effects on the skin and hair, with simultaneous effective cleansing effect, especially if the consumer uses the shampoo at high frequency (several times a week). The article discusses: the definition of micellar shampoo, the composition of traditional shampoos and issues related to the creation of micellar aggregates. The results of a comparative analysis of a market micellar shampoo well known brand with standard shampoos obtained on the basis of original recipes are also presented. Classical compositions developed for the article differed in the type of the basic surfactant used. Three formulas included: Sodium Laureth Sulfate (abbreviated SLES), Sodium Lauryl Sulfate (abbreviated SLS) and Disodium Laureth Sulfosuccinate (abbreviated DSLSC) used at a concentration of 5% by weight. In addition to these compounds, the hair washing composition included: Cocamidopropyl Betaine, Glicerine, Polyquaternium-7, Sodium Chloride, Sodium Benzoate and Potassium Sorbate, Lactic Acid and Aqua. Micellar market shampoo and original shampoos were compared to viscosity, foam-forming properties and ability to emulsify oil soils. Moreover, the values determining the surface activity of their aqueous solutions: surface tension and the size of the micelles formed were determined. It was found that the reference micellar shampoo was characterized by higher: viscosity and ability to emulsify fatty soils in relation to the values obtained for classical shampoos. All washing compositions showed comparable values of surface tension and foaming properties. On the basis of observation of the size of aggregates present in aqueous solutions of the tested shampoos, they can be described as micellar shampoos.
