Parfums Index. décimale : 668.5 Parfums et cosmétiques Résumé : The safety of personal care and cosmetic products is at the top of every manufacturer's list of priorities, and a high level of safety would not be possible without the use of preservative ingredients which eliminate the growth of organisms within aqueous formulations. However, the range of available preservative ingredients is very limited, meaning that formulators must be creative with their anti-microbial strategies. With this in mind, Ashland has introduced a new aromatic for the personal care and cosmetics industry that also contributes to the preservation of end use products delivering multifunctional benefits including broad anti-microbial protection. Conarom TM b aromatic addresses growing consumer demand for multifunctional and sustainable ingredients. The aromatic is based on naturally derived hops extract and the nature identical phenylpropanol. It adds a gentle flowery-to-spicy fragrance to differentiate and impart additional allure to the end use formulation. At dosages of 0.3 to 2% it contributes to microbial stabilisation by delivering broad antimicrobial protection as a secondary effect. Conarom b aromatic can be added to formulations at any phase of production when worked into products at ambient temperature. Ashland say that typical uses include body and skin care emulsions, sun care, shampoo and body washes, conditioners and wet wipes. Personal Care magazine spoke to Karen Winkowski, PhD, global technical director, Preservatives and Microbial Technology, Ashland, and Andrea Wingenfeld, global marketing manager, Preservatives and Medical Care, Ashland, to discover more about the company's approach to preservation and the new multifunctional ingredient.

Laine Mordants (chimie) Nappage Résistance au lavage Teinture -- Fibres textiles Index. décimale : 667.3 Teinture et impression des tissus Résumé : Wool fabrics can be dyed with synthetic dyes and even with natural dyes. To present a different aspect to the coloration of wool, the current study was focused on a topping process (ie, the dyeing of wool that was already dyed) with different natural dye sources. For this purpose, the fabrics that were already dyed with a natural dye source were once again dyed with two different natural dyes. In bottom dyeing (bottoming), fabrics were dyed with hops (Humulus lupulus L.) in the presence of different mordanting agents. Then the dyed, washed and dried samples were once again dyed (topping) with two different natural dye sources. For topping, powdered madder and acorn were tested in direct dyeing of wool samples. Finally, the colour changes were analysed with the use of a spectrophotometer. The study demonstrates that such a process (ie, bottoming with hops in the presence of different mordanting agents and then topping with madder or acorn) can be a way of obtaining different shades and colours with sufficient/good fastness values by natural dyeing.
