[0027] The present invention also provides a method of making laundry detergent compositions, and preferably low density laundry detergent compositions, without departing from the spirit and scope of the invention. The term "low density" as used herein means that the particles have an apparent density including air bubbles of 0.6 g / ml or less. The present invention provides a process for preparing a laundry detergent composition by drying the laundry detergent composition by heat generated by the neutralization of an acidic component with a basic component without the use of an additional drying step, wherein the process comprises The following steps: (S1) prepare acidic water-soluble polymers and anionic surfactants as acidic components, and prepare alkaline builders as alkaline components; (S2) add 0.1 to 15 parts by weight to the mixer The water-soluble polymer in the acidic form and the anionic surfactant of 5-20 parts by weight and the alkaline builder of 10-70 parts by w...

Embodiment 1

[0030] Embodiment 1 (preparation of coating organic acid)

[0031] Citric acid was used as the organic acid to prepare the coating organic acid. The coating was prepared by mixing 90 kg of anhydrous citric acid with 4 kg of silicon compound polydimethylsiloxane used as a binder component in a mixer for 1 hour, followed by adding and mixing 6 kg of silicon dioxide as a coating component. Apply organic acid.

[0032] Examples 2 and 3 and Comparative Examples 1 and 2 (Preparation of Laundry Detergent Compositions)

[0033] Based on the components and contents listed in Table 1 below, the compositions of Examples 2-3 and Comparative Examples 1-2 were prepared by simply mixing the components using a high-speed mixer. Specifically, the composition is prepared by a conventional method comprising the steps of mixing all components except other additives and coating an organic acid to prepare a granulated powder, followed by mixing the granulated powder with other additives and coating organic acids.

Abstract

A lateral force resisting system according to the present disclosure includes a metal lateral force resisting panel and holdowns. A foundation bolt placement template may be used to locate and support the foundation bolts during fabrication of the foundation and to further secure the frame foundation interface. The metal lateral force resisting panel may be formed from a single piece of material and may include a plurality of ductility apertures forming lateral force resisting elements to enable the panel to flex without catastrophic failure. In a hybrid configuration, a wooden structural frame may be combined with the metal structural panel. The structural panel may be subdivided into multiple panes using ductility apertures to tailor the response of the panel to the lateral force load. The holdowns secure the rigid structural panel to the foundation bolts and may be either a folded strap and pin configuration or self-tightening.

Description

technical field [0001] The invention relates to a laundry detergent composition capable of improving the touch of washed clothes, and a preparation method of the laundry detergent composition. Background technique [0002] In general, the washing effect is better in soft water than in hard water which includes a large amount of magnesium ions and calcium ions. This is why powder detergents usually include water softeners such as zeolites. A water softener such as zeolite, etc., which is mainly used in the prior art has a problem in that it remains in laundry even after the laundry is rinsed due to its water-insoluble property. And the problem is that since it takes a relatively long time to form ion clathrates, the softening effect of hard water is rather slow, so the calcium ions remaining in the clothes during washing and the carbonic acid ionized by alkaline builders, etc. The root ions are bonded to form calcium carbonate, and the generated calcium carbonate remains in...
