Hydrotropic agent
If being the form of liquid, then liquid detergent composition can optionally comprise hydrotropic agent, and it can stop Formation of liquid crystals.Therefore, hydrotropic it is added with the clarification that helps compositions/transparent.Suitable hydrotropic agent includes but not limited to propylene glycol, ethanol, glycerol, urea, benzene sulfonate, toluene fulfonate, xylenesulfonate or cumene sulfonate.Suitable salt includes but not limited to sodium, potassium, ammonium, monoethanolamine, triethanolamine.Sulfonate may be considered as anion surfactant as defined herein.Preferably, hydrotropic agent is selected from propylene glycol, xylenesulfonate, ethanol and urea to provide optimum performance.Hydrotropic amount is generally 0 to 30%, preferably 0.5 to 30%, more preferably 0.5 to 30%, most preferably 1 to 15%.
Enzyme
Enzyme can also be present in preparation.Preferred enzyme includes protease, lipase, pectin lyase, amylase, at, cellulase, mannase.If it does, can with known enzyme stabilizers, for instance boric acid makes described enzyme stable.

The method preparing preparation
In ambient temperature (about 22oC), under, use Janke&KunkelIKARW20 overhead type stirrer, with the shear rate of 150rpm, water and hydrotropic agent are mixed 2-3 minute.Before adding surfactant and fatty acid, add salt and alkali matter (alkalis) and mix 5 minutes.Slight heat release will be shown at this azeotropic mixture.< after 30 ° of C, add cationic polymer (LR400 added as an aqueous solution) solution and any remaining ingredient, such as aromatic, preservative, dyestuff and polysiloxanes allowing to cool to.Add described polysiloxanes with 1wt.%, and it is added in the form of an emulsion.
Test 4 kinds of polysiloxanes, the PDMS of a kind of standard and 3 kinds of anion polysiloxanes from Shin-Etsu:
·100CstPDMS(‘X’)
The carboxyl polysiloxanes that X22-3710E (1) chain is intermediate modified, it has vertically or pendant is in the carboxyl of main silicone matrix
X22-162C (' Y ') both-end carboxyl polysiloxanes, it has the carboxyl at each end position place at main silicone matrix
X22-3710 (' Z ') monofocal end carboxyl polysiloxanes, it has the carboxyl at an end position place at main silicone matrix
Polysiloxanes 1 is according to the present invention, and polysiloxanes X, Y and Z are as a comparison.
Stability/turbid mixed measurement
4 kinds of polysiloxanes are formulated in every kind in 6 kinds of preparations (A-F).Fetch the sample from every kind of preparation and add it to 1cm cuvette, and being measured by UV-Vis, taking the reading under 500nm.This UV-Vis measurement provides the turbid mixed level of product.Relatively low reading shows less turbid mixed.
