[0123] The samples reported in Table 4 below were prepared.

[0124] Table 4

[0125]

[0126] HTTEAQ and fatty alcohol were the same as used in previous samples.

[0127] The examples were cold ground as described in Example 1.

[0128] The room temperature stability of each embodiment is recorded in the table below (all viscosities are at 106 s with Haake RT20 viscometer -1 measured at shear rate).

[0135] Prepare the following formulations:

[0136] 12.35% HTTEAQ

[0137] 1.5% fatty alcohol

[0138] 0.93% fragrance

[0139] A small amount of preservatives, dyes, defoamers

[0140] water to 100%

[0141] HTTEAQ and fatty alcohol are the same as in previous examples. This formulation was prepared as described in Example 1, followed by cold milling. Samples were taken after cold milling at 0, 1 BV (batch volume), 2 BV and 2.5 BV.

[0142] Viscosity changes with cold grinding (at 20 and 106s -1 down, expressed in cps)

[0143] 0BV 830 / 300

[0144] 1BV 330 / 135

[0145] 2BV 177 / 80

[0146] 2.5BV 116 / 54

[0147] The results show that product viscosity can be controlled by cold grinding. Furthermore, it was shown that there is no risk of shear-induced flocculation with longer milling, illustrating the excellent stability of the base formulation.

Abstract

A method of making a fabric conditioning composition comprising providing: from 8 to 30% by weight of a quaternary ammonium softening material comprising a mixture of mono-ester, di-ester and tri-ester linked saturated components, a fatty complexing agent selected from fatty acids and fatty alcohols in an amount such that the weight of the mono-ester linked quaternary ammonium material to the fatty complexing agent is from 2.5 : 1 to 1 : 2, water, and perfume, the composition being free from non-ionic surfactant and added electrolyte, and subjecting the composition to a high shear and / or milling step.

Description

field of invention [0001] The present invention relates to concentrated fabric conditioner compositions, and more particularly, the present invention relates to concentrated fabric conditioner compositions having desirable viscosities over a broad temperature range. Background of the invention [0002] It is known to provide liquid fabric conditioning compositions to soften fabrics during the rinse cycle. [0003] Such compositions comprise less than 7.5% by weight of softening actives (in which case the composition is referred to as a "dilute" composition), 8% to about 30% by weight of actives (in which case the Compositions are referred to as "concentrated" compositions) or greater than about 30% by weight active material (in which case the compositions are referred to as "ultraconcentrated" compositions). [0004] Thick and super-concentrated compositions are desirable because they require smaller packaging and are therefore more environmentally compatible than thin or s...
