[A hygienic study of new raw materials for cosmetic agents and household chemical preparations].
Studies are performed on the new Bulgarian raw materials "Aminookis" (AO) and "Dezodorirashch agent" (DA) the plants "Alen Mak"--Plovdiv and "Hyaluron"--Sofia. Chemical, toxicological and microbiological studies are carried out. Thin-layer chromatographic and spectrophotometric methods for determination of AO, hyaluronic acid and DA are developed and chemical studies on cosmetics, prepared with them, are carried out. During the repetition of a 21-day experiment on guinea pigs the threshold irritative concentrations--10% for AO and DA (as trade products) are determined. This shows that they are moderate contact irritants. The hyaluron has no irritative effect. By maximizing test with guinea pigs is established the absence of contact allergy for DA and AO. At index of sensibilization 10% the hyaluron falls in the group of weak allergens. The spectra of action are studied and the minimum suppressing concentrations of AO and DA are defined. It is established that the most resistant to effect with these cosmetics are the representatives of the families: Pseudomonas, Klebsiella, Escherichia, Salmonella. Recommendations are made to use "Aminookis" (AO) in shampoos to 8%, deodorizing agent in deodorants to 2% and "Hyaluron" in creams to 20% (as trade products).
