Abstract

The invention discloses a skin cleaner. The skin cleaner comprises the following components in percentage by weight: 20-50% of glycerin, 10-20% of dodecanoic acid, 6-12% of tetradecanoic acid, 4.5-9.0% of potassium hydroxide, 3-8% of coconut monoethanolamide, 0.5-3% of carbopol 940, 0.1% of EDTA (Ethylene Diamine Tetraacetic Acid)-disodium and the balance of water. The skin cleaner is paste, has the advantages of abundant foam, easiness for smearing and flushing, convenience and sanitation and is particularly suitable for consumers being used to using a perfumed soap. The invention also provides a preparation method of the skin cleaner. After being used, the skin cleaner prepared by using the method is easy to flush like the perfumed soap, has the specific unsmooth feeling of the perfumed soap and is more convenient to use and easier to store and guarantee the quality than the perfumed soap.

Description

A kind of skin cleaner and preparation method thereof

Technical field

The present invention relates to a kind of skin cleaner, be specifically related to a kind of skin cleaner of paste.

Background technology

Traditional perfumed soap is solid, and use inconvenience and difficult preservation are put, easily contaminated and rotten, and fragrance is easy to volatilize and disperses in addition.

According to statistics, there is such group only to like using perfumed soap, reason to be can allow skin have a kind of distinctive " puckery " dry and comfortable sensation after perfumed soap is washed.Yet general body wash be difficult for to rinse, the residual meeting of its tensio-active agent smooth slipping with it after allowing this class people feel to wash, very uncomfortable.

Directly with soda soap (lipid acid and sodium hydroxide make), adding water or polyvalent alcohol dilution, to dissolve the liquid soap making extremely unstable, easily occurs layering, affects use.

Also just like < < liquid toliet soap > > application number 201310657290.2 of Lin Xiaoli, mention with soft soap and make liquid toliet soap at present; The < < liquid toliet soap > > application number 201110098897.2 that Nantong Hong Lida Knitting Company Ltd mentions, mentions with potash soap (lipid acid and potassium hydroxide make) and makes liquid toliet soap.

The general viscosity of liquid soap is lower, lower than the viscosity (30 ℃, be less than 2000mPaS) of common body wash, uses inconvenient.Because be not suitable for covering bottle dress with general wearing, during use, easily pour out a lot, cause waste.And with the bottle dress with pump head, will increase production cost.

In the patent of above-mentioned two applications, all mention tensio-active agents such as using sodium lauryl sulphate (being ether alcohol sulfate), fatty alcohol-polyoxyethylene ether (being polyethoxylated fatty alcohol) and fatty alcohol-ether sodium sulfate (being fatty alcohol Vinyl Ether sodium sulfate), and large usage quantity, cause detersive power easily to cause too by force the excessive degreasing of skin, injured skin.Meanwhile, these one-tenth branches increase " the sliding sense " after washing, and can not meet perfumed soap " fan's " unique need.Its reason is: the preparation of soft soap or become liquid, or just become to be difficult for to disperse thick, if do not add other compositions, be difficult to be made into easy to apply, easily disperse paste easy to use.

Summary of the invention

Potassium hydroxide of the present invention, chemical formula KOH, can with the lipid acid generation saponification reactions such as laurostearic acid, TETRADECONIC ACID, obtain having surface-active fatty acid potassium soap.

Coconut Fatty Acid Monoethanolamide of the present invention, CAS:68140-00-1, good thickening property, froth stability, emollient and stability in hard water etc.Compatibleness is good, and has fabulous synergistic function.

Acritamer 940 of the present invention is a kind of vinylformic acid cross-linked resin, good rheology control agent, the effect that has thickening to suspend.

EDTA-2 sodium of the present invention is a kind of metal chelator, has the effect that strengthens washing effect.

Preferably, described skin cleaner comprises the component of following weight percent: glycerine: 50%; Laurostearic acid: 20%; TETRADECONIC ACID: 12%; Potassium hydroxide: 9%; Coconut Fatty Acid Monoethanolamide: 3%; Acritamer 940: 0.5%; EDTA-disodium: 0.1%; Surplus is water.

Preferably, described skin cleaner also comprises sanitas, and the weight percent of described sanitas in described skin cleaner is 0.1%.Sanitas of the present invention adds when skin cleaner temperature is down to below 50 ℃.

Preferably, described sanitas is Imidurea.Imidurea of the present invention is the gentle sanitas of a kind of used for cosmetic.

Preferably, described skin cleaner is paste.

Preferably, the viscosity of described skin cleaner in the time of 30 ℃ is 3000～30000mPaS.

The present invention also provides the preparation method of skin cleaner described above, said method comprising the steps of:

(1) in agitator, add water, EDTA-disodium, potassium hydroxide, Acritamer 940 and glycerine, heat while stirring;

(2) when temperature rises to 80 ℃, add laurostearic acid and TETRADECONIC ACID, at 80 ℃, after stirring and dissolving, add Coconut Fatty Acid Monoethanolamide, maintenance temperature stops heating after being stirred to dissolving, obtains described skin cleaner.

Beneficial effect of the present invention is: the skin cleaner that the invention provides a kind of paste, this sanitising agent has advantages of that foam is abundant, easy to apply, easily flushing and convenient and healthy, meet especially the human consumer that custom is used perfumed soap, the present invention also provides the preparation method of described skin cleaner, by easily rinsing as perfumed soap after the skin cleaner use that adopts the method to prepare, there is perfumed soap distinctive " puckery " sense, but more easy to use than perfumed soap, more easy to store and guarantee the quality.
