• One suitable method is to form a molten mixture of the cationic fabric softening agent and the fatty acid, add this molten mixture to water with stirring to form a dispersion and thereafter add the nonionic surfactant and any optional ingredients.
• Another suitable method is to add the nonionic surfactant to the molten mixture before the dispersion is formed.
• a liquid fabric softening composition was made as follows.
• the cationic fabric softening agent and the fatty acid were premixed and heated together until clear (60-75 ° C).
• the molten mixture thus formed was added over a period of at least one minute, via a dip pipe, to water at 45-60°C, with constant stirring to form a dispersion.
• Other minor ingredients including perfume were added with constant stirring whilst the temperature of the dispersion was greater than 35°C.
• the nonionic surfactant was most preferably added after the mixture had cooled to 35 ° C or below.
• Example 1 was repeated except that the Nonidet LE 6T was excluded from the composition (Example 1 A).
• a freeze thaw cycle in this context involves storing 100 g of product in a screw-capped polyethylene bottle for 16 hours at a temperature of -12 ° C or less. Such low temperatures are essential to ensure that the products are completely frozen. The product is then allowed to thaw at ambient temperatures for 8 hours.
• Example 1 After 1 freeze thaw cycle Example 1 gave a composition which was slightly thicker than normal. After 3 and 6 freeze thaw cycles Example 1 gave a composition which had normal rinse conditioner rheology, ie. was mobile and could be poured in a continuous stream. Example 1A after 1, 3 and 6 freeze thaw cycles gave a composition which was just mobile but which did not pour in a continuous stream.
• compositions with the following formulations expressed as weight % were prepared by the method previously described.
• Example 2L For comparison purposes a composition containing no nonionic (Example 2L) was prepared and tested. In Example 2A a level of APG 300 of 0.2% rather than 0.4% was used. Each composition was subjected to the following cap dispenser test after 1 and 3 freeze thaw cycles.
• Products were allowed to recover from freezing and a known amount (usually 20 grams) was weighed into an internally screw threaded cap with a total capacity of approximately 25 cm 3 and of known weight. The cap was then inverted over a waste container for 10 seconds and re-weighed. The results obtained are expressed as a percentage of the amount of product weighed into the cap. Prior to freezing, the samples were found to leave up to approximately 10% residue in the cap.
• Nonidet LE6T is replaced by Tween 20, Alfol 1214-7, Alfol 1214-11, Alfol 1214-13, Brij 30, Brij 35, Lutensol A07, Lutensol A08, and Synperonic All.
• This example demonstrates the effect of increasing levels of nonionic surfactant on the freeze-thaw stability of a 4.2% active with a ratio of Arquad 2HT: Pristerene 4916 of 6:1 by weight and a perfume level of 0.13%.
• the compositions were prepared by the method previously described.
• the levels of nonionic are expressed in terms of wt% of the final formulation.
• the products were assessed after one freeze thaw cycle via the cap dispenser test described above.
• This example demonstrates the effect of low levels of Nonidet LE 6T on formulations other than those containing 4.2% active and a 6:1 weight ratio of cationic fabric softening agent to fatty acid.
• the compositions were prepared as described above and the percentage ingredient refers to their weight % in the final product.
• compositions were evaluated according to the cap dispenser test as described above.
• compositions with the following formulations were prepared as described above. Once again the amount of each ingredient refers to weight % in the final product composition.
• compositions were assessed visually after recovery from 1 freeze thaw cycle.
• addition of a nonionic surfactant improved the appearance and flow characteristics of the composition.
• This Example demonstrates that the beneficial effect of adding nonionic surfactant is not restricted to compositions containing Arquad 2HT and Pristerene 4916.
