Description
Technical field
The present invention relates to a kind of washing liquid, belong to daily use chemicals cleaning product technical field, particularly relate to a kind of not solvent-laden Superconcentrated washing liquid and preparation method thereof.
Background technology
Washing composition is one of daily life requisite.Washing liquid as one of washing composition, because that it has is easy to use, dissolving rapidly, cold washing is effective and to advantages such as fabric and skin gentlenesses, kept in recent years surgingly increasing, the market volume of production and marketing rises rapidly, thereby becomes the main direction of washing composition development always.And Superconcentrated washing liquid is on the basis with common washing liquid advantage, more has active matter content height, strong detergency concurrently, production cost is low, the carbon emission amount is few, save wrapping material and reduce advantages such as transportation cost.Therefore more meeting the requirement of the sustainable development of socio-economy, is the main development trend of following washing composition.
Though Superconcentrated washing liquid has above-mentioned many remarkable advantages, hyperconcentration product real on the current market is rarely found.One of the main reasons is because the prescription active matter content is higher, and causing developing related products has certain technical difficulty, gel appears easily when producing, the product low-temperature stability is bad and when using in water problem such as bad dispersibility.
In order to overcome above-mentioned technical barrier, prepare qualified Superconcentrated washing liquid product, prior art mainly is by add a large amount of solvents in prescription, as ethanol, propylene glycol, monoethanolamine, trolamine etc., to improve the solubleness of tensio-active agent and auxiliary agent, and promote the consistency of each component, make system keep stable homogeneous and promote the solvability of product or dispersiveness etc.For example Chinese patent application CN201110160696.0 discloses a kind of environment-friendly type hyperconcentration biological enzyme laundry liquid and preparation method thereof, and it has used the solvent of 0.5-30 part.Chinese patent application CN200810247478.9 discloses a kind of transparent high-concentration laundry detergent and preparation method thereof, added in this washing composition account for washing composition weight 8-18% monoethanolamine as solvent.
As seen, can use a large amount of solvents usually in the Superconcentrated washing liquid formula of prior art, thereby can reach solubleness and the consistency that improves raw material, and can reduce product viscosity, the convenient effect of producing and using.But also have obvious defects, the soil-removing action of these solvents own is less usually, can not promote washing functions, but can significantly increase formulation cost, reduces the ratio of performance to price of product; Also can bring very big smell to product simultaneously, when producing and use, may have certain potential safety hazard; In addition, these solvent discharges also can cause detrimentally affect to environment in environment at last.
In addition, current commercially available Superconcentrated washing liquid product, also having a shortcoming clearly is exactly that low-temperature stability is bad, and most of products will become muddy even freeze about 0 ℃, therefore cause influencing when microthermal climate the consequence of sale and the use of product.
Therefore, press on the detergent market a kind of not solvent-laden, safety and environmental protection, high low temperature good stability, cost performance height, strong detergency, the Superconcentrated washing liquid of the easy rinsing of low bubble.
