    • A powder laundry detergent has improved solubility in the laundering solution and improved dispensability by incorporating an acidulant that, in its acid form, is sparingly soluble in water and, in its salt form, is soluble in water. In particular, the acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 8 %, preferably no greater than about 0.7 % by weight at 25 DEG C and in a salt form are soluble in water at least in an amount of about 15 % by weight at 25 DEG C. A method of improving the solubility of a powder detergent includes admixing an acidulant in the powder detergent where the acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 8 %, preferably not greater than about 0.7 % by weight at 25 DEG C and in a salt form are soluble in water at least in an amount of about 15 % by weight at 25 DEG C.

    • A powdered laundry detergent is provided with (a) a powder laundry detergent base that includes an inorganic carrier and a surfactant and (b) post-added acidulant and discrete whitening agent particles to provide a detergent having improved cool water solubility with bulk color deterioration caused by whitening agents being minimized. The detergent includes from about 5 % to about 80 % of an inorganic carrier, from about 1 % to about 90 % of a detergent surfactant, from about 0.1 % up to about 15 % of an acidulant and from about 0.1 % up to about 30 % of the discrete whitening agent particles. The acidulant is selected from the group of acids that in an acid form are soluble in water in an amount not greater than about 8 %, preferably not greater than about 0.7 % by weight at 25 DEG C and in a salt form are soluble in water at least in an amount of about 15 % by weight at 25 DEG C. The whitening agent particles include a whitening agent and a surfactant. The whitening agent surfactant can consist of those anionics, nonionics, zwitterionics, ampholytics, cationics, and mixtures thereof that are solids in a temperature range of from about 32 DEG F (0 DEG C) to about 180 DEG F (82 DEG C). In a more preferred form, the whitening agent particles consist of a whitening agent, a surfactant, preferably an anionic surfactant, and water.
    • 一种粉状衣物洗涤剂提供有(a)包含无机载体和表面活性剂的粉末衣物洗涤剂基质和(b)后添加的酸化剂和分散的增白剂颗粒,以提供具有改善的冷水溶解度的洗涤剂,从而导致体积颜色劣化 美白剂最小化。 洗涤剂包括约5%至约80%的无机载体,约1%至约90%的洗涤剂表面活性剂,约0.1%至约15%的酸化剂和约0.1%至约30 %的离散增白剂颗粒。 酸化剂选自在酸形式中可溶于水的酸组,其量不大于25℃,优选不大于约0.7重量%,盐形式可溶于水 在25℃下至少为约15重量%。增白剂颗粒包括增白剂和表面活性剂。 美白剂表面活性剂可以由在约32°F(0℃)至约180°(82℃)的温度范围内的固体的那些阴离子,非离子,两性离子,两性离子,阳离子及其混合物组成。 在更优选的形式中,增白剂颗粒由增白剂,表面活性剂,优选阴离子表面活性剂和水组成。

    • A powdered laundry detergent is provided with discrete whitening agent particles that do not adversely affect the bulk appearance of the detergent during storage. The detergent includes from about 5 % to about 80 % of an inorganic carrier, from about 1 % to about 90 % of a detergent surfactant, and from 0.1 % up to about 30 % of the discrete whitening agent particles. The whitening agent particles include a whitening agent and a surfactant. The surfactant for the whitening agent particle includes those anionics, nonionics, zwitterionics, ampholytics, cationics, and mixtures thereof that are solids in a temperature range of from about 32 DEG F (0 DEG C) to about 180 DEG F (82 DEG C). The whitening agent particles, in a more desirable form, include a whitener and water. The particles are formed by extruding a homogenous mass into discrete particles. The homogenous mass includes either a whitening agent, a surfactant, and optionally a plasticizer or a whitening agent and water.
