“…Cosmetics wastewater samples were also effectively treated by dissolved-air flotation, assisted by coagulation-i.e., with Al 2 (SO 4 ) 3 [28]. The use of nanoparticles as adsorbents attracted widespread interest because they have a large surface area-to-volume ratio and the capability for functionalization with different molecules.…”

Flotation in Water and Wastewater Treatment

Flotation constitutes a separation process that originated from mineral processing. Nowadays, wider applications have been found and compared to flotation for water and wastewater treatment. Stress in the present review paper was mainly applied to heavy metal ions recovery by flotation and the respective mechanism followed, being either ion, precipitate, or sorptive flotation. In the latter case, the use of adsorbents is included (such as powdered activated carbon, zeolites, and goethite), as well as various biosorbents. The flotation of the following metals was reviewed: copper, zinc, nickel, lead, iron, chromium, arsenic, gold, and others. The bubble generation method could be applied for typical dispersed-air flotation column, electroflotation, or dissolved-air flotation; the latter being the most appropriate established technique in water treatment. The role of particle size (for example, studying flotation of salt-type mineral fines) was also examined.

“…The wastewater from the production of cosmetics characteristically has a very diverse chemical composition (Bogacki et al 2017), its most common components are surfactants (Aloui et al 2009), oils and fats (Bautista et al 2007), phenols (Perdigon-Melon et al 2010), as well as siloxanes and fragrances (Naumczyk et al 2013). Among the different types of surfactants found in cosmetic wastewater, the most common and the most abundant ones are anionic surfactants (Aloui et al 2009;Gohary et al 2010).…”

Coagulation is often used for the pre-treatment of industry wastewater, with effectiveness strictly dependent on technological conditions. This study aimed at determining what technological parameters of coagulation of cosmetic industry wastewater provide the highest efficiency of clarification. The dosages of reagents, the order of dosing, as well as the one-and two-stage processes were investigated. The samples of raw wastewater were collected from average daily effluent from a cosmetics manufacturing plant. Liquid coagulant PIX 111 (FeCl 3 ) and NaOH as a pH-adjusting agent were used. Jar-test experiments were carried out to determine the optimum conditions for turbidity and total organic carbon (TOC) removal. The efficiency of clarification was high (90-99%) across a wide range of pH values (6-9) and coagulant doses (0.5-1.25 mL/L). What is important is that the coagulant dose of 0.56 mL/L provided 97.6% clarification efficiency without the addition of the alkali. The minimal stoichiometric excess of alkalinity for effective coagulation was 0.5 mmol/L. In all samples, the removal efficiency for TOC was lower than for turbidity, because some of the organic carbon forms were non-coagulating dissolved compounds. The wastewater from tonic and fluid production was very susceptible to coagulation. The addition of the coagulant before the alkali resulted in better wastewater treatment efficiency than the reverse order. Single-stage process with optimal doses of the reagents allowed to clarify wastewater to a level of 10 NTU. On the other hand, the two-stage process brought the turbidity down to 1 NTU level.

“…Test compounds, namely β-cyclocitral oxime, citronellal oxime, perillaldehyde oxime were supplied by the Department of Bioorganic Chemistry, Faculty of Chemistry, Wrocław University of Science and Technology. This fragrances can be further used in household chemicals, cosmetics and perfumes or can become a substrate for the synthesis of another odour components [8]. Due to the increasingly frequent withdrawal of fragrances from the market and use, it is necessary to search for new fragrances.…”

Preliminary ecotoxicity assessment of selected flavour and fragrance compounds using Microtox assay

The bioluminescence inhibition bioassay using marine bacteria Vibrio fischeri is widely used as a tool to assess the toxicity of chemical compounds, because of the many benefits comprising cost and time effectiveness, rapidness, sensitivity, and ease of operation. In addition, the test is used for various types of organic and inorganic compounds. Due to the insolubility of organic compounds in water, a suitable solubilizer should be applied. The ecotoxicity of the solvent should be negligible in relation to marine bacteria. On account of superior human activities the synthesis of new chemical substances is inextricably linked to the emergence of chemical compounds that are a potential threat on environment. A Microtox system utilizing the 81.9% Basic Test with 14 dilutions was applied to pre-evaluate the ecotoxicity of β-cyclocitral oxime, citronellal oxime and perillaldehyde oxime. Substances solutions with an initial concentration of 0.036% in DMSO were prepared. The preliminary results show that the studied scent compounds are characterized by quite high toxicity. In order to confirm the received ecotoxicity values, it is necessary to carry out additional surveys using another range of concentrations and biotests on organisms at each trophic level.
