Title
(EN) BAR COMPRISING ACID-SOAP COMPLEX AS STRUCTURANT AND LOW LEVELS OF SYNTHETIC SURFACTANT
(FR) BARRE COMPRENANT UN COMPLEXE ACIDE-SAVON COMME STRUCTURANT ET PRESENTANT DE FAIBLES NIVEAUX DE TENSIOACTIF SYNTHETIQUE
Abstract
(EN) The invention relates to soap/free fatty acid bars in which high amounts of free fatty acid (i.e., greater than 35 %, preferably greater than 40 % and ratio of FFA to soap greater than 1:1) and low levels of synthetic may be used. In the bar, the free fatty acid is believed to form a complex which is believed to act as a structurant, thereby allowing less use of synthetic surfactant. The bar should require less synthetic surfactant. Total amount of unsaturated material in soap and fatty acid should be no higher than 15 %. In a further embodiment of the invention, the bar may be made by a neutralization process whereby fatty acid is combined with caustic (e.g., lower than 50 % caustic) to form soap and free fatty acid in defined amounts or proportions.
(FR) L'invention concerne des barres à complexe acide gras libre/savon, avec un taux élevé d'acide gras libre (à savoir plus de 35 %, de préférence plus de 40 %, et rapport acide gras libre/savon supérieur à 1:1), et par ailleurs avec de faibles niveaux de tensioactif synthétique. Dans ce type de barre, l'acide gras libre est censé former un complexe censé agir comme structurant, permettant d'utiliser moins de tensioactif synthétique. Ce type de barre doit nécessiter moins de tensioactif synthétique, et la quantité totale de matériau non saturé dans le savon et l'acide gras ne doit pas dépasser 15 %. Selon une variante, la barre peut être réalisée par le biais d'une technique de neutralisation, moyennant quoi l'acide gras est combiné avec un caustique (par exemple, moins de 50 % de caustique) pour constituer le savon et l'acide gras libre dans des quantités ou proportions définies.
