Technical field

The present invention relates to a kind of paste sanitising agent.

Background technology

Known is in the sanitising agent at fatty acid soaps, just can form liquid state by cooperating more short chain fatty acid and improving degree of neutralization, in contrast, then can form the paste form by cooperating more longer chain fatty acid and reducing degree of neutralization.

As above said paste sanitising agent be compared to liquid cleaning agent have the foam exquisiteness be creaminess, feel comfortable, cleansing power good, to features such as skin irritation are little.Therefore the paste sanitising agent is used as the cleansing milk use under many circumstances.For the paste sanitising agent, people are that the skin moisture retention after raising its foaming properties, cleaning performance and the cleaning has carried out inquiring into research (patent documentation 1, patent documentation 2).

The as above paste sanitising agent of said fatty acid soaps system is because it is obvious along with changes in hardness that temperature variation produces, so inquired into the situation of allocating the cationic macromolecular compound in patent documentation 3.But, even such paste sanitising agent, normally used the time, because the fluidity of sanitising agent is difficult to disintegration, poor ductility more firmly.Therefore, the paste sanitising agent is not suitable as the use of whole body sanitising agent.Specifically, when a lot of users clean whole body, can use the instruments such as towel.When towel is taken the paste sanitising agent, because its fluidity is hard, poor ductility, sanitising agent can accumulate a place in towel, can not launch equably.Therefore, diminish with regard to the contact area that has produced paste sanitising agent and water, the solvability in water is slack-off, is difficult to the problems such as foaming.

Employed composition (C) is the nonionic polymkeric substance of selecting from hydroxypropylguar gum, polyvinylpyrrolidone and polyoxyethylene glycol among the present invention.Wherein be preferably hydroxypropylguar gum.Consider that from the viscosity of sanitising agent and whipability viewpoint the weight-average molecular weight of these polymkeric substance is preferably 40,000～3,000,000, more preferably 300,000～2,750,000, further be preferably 2,000,000～2,500,000.

As the more specifically example of nonionic polymkeric substance, can enumerate ALKOX series (polyoxyethylene glycol that bright one-tenth chemical industrial company makes): ALKOX-E30 (weight-average molecular weight 300,000～500,000), ALKOX-E-45 (weight-average molecular weight 600,000～800,000), ALKOX-E-60 (weight-average molecular weight 1,000,000～1,200,000), ALKOX-E-75 (weight-average molecular weight 2,000,000～2,500,000), ALKOX-E-100 (weight-average molecular weight 2,500,000～3,000,000); Luviskol series (polyvinylpyrrolidone that BASF Japanese firm makes): Luviskol-K30 (weight-average molecular weight 40,000～60,000), Luviskol-K90 (weight-average molecular weight 1,200,000); JAGUAR-HP series (hydroxypropylguar gum that Rhodia Inc makes), JAGUAR-HP8, JAGUAR-HP105, JAGUAR-HP-120 (any weight-average molecular weight all is 2,200,000) etc.

Sanitising agent among the present invention is by using composition (B) cation property copolymer and composition (C) nonionic combination of polymers, can show the peculiar effect that paste sanitising agent had not before this showed.For example, paste sanitising agent of the present invention has and easily extends with good, the distinctive viscosity sense of the affinity of skin and towel and on skin and towel and the easy feature such as expansion.Paste sanitising agent before this is because viscosity is high, and it is poor to exist with the affinity of moistening hand and towel etc., the problems such as easily landing (easily because error and tumble above towel etc.).But paste sanitising agent of the present invention and skin and towel etc. are very easily affine.And, with hand or towel in the process that skin is smeared out, because toughness can spread apart as going between glossily.Its result can equably, fully extend sanitising agent.So, can increase the sanitising agent of thinly expansion and the contact area of water, also can improve the dispersiveness (solvability) in water.From such viewpoint, composition (B) is preferably 5: 1 with (C) mass ratio～and 1: 5, more preferably 4: 1～1: 4, further be preferably 2: 1～1: 2.

Next, discuss for alveolar substance.Separately during gradation composition (B) cation property copolymer, when perhaps increasing the amount of cationic polymers, it is hard and thin that foam just becomes in sanitising agent, and the foam that is risen during with towel can not be flooded in towel (, can not bubble fully).Therefore, such sanitising agent is not suitable for cleaning whole body.Separately during gradation composition (C) nonionic polymkeric substance, when perhaps increasing the amount of nonionic polymkeric substance, because the foam that beginning is risen is very large, the foam that is risen during the use towel can reach the degree that is flooded in towel in sanitising agent.But the retentivity of the foam that is risen is very poor, and foam will disappear in cleaning the whole body process.Based on this, the contriver thinks: the cation property copolymer of composition (B) to the effect of soap film is, the negative charge that hydrophobic group is pointed to the soap molecule of air one side by high molecular positively charged ion position partly produces to interact strengthens soap film.Thus, foam is not disappeared and attenuate, keep muchly.On the other hand, the contriver thinks: composition (C) nonionic polymkeric substance to the effect of soap film is, thereby liquid-gas interface is exerted an influence the stability that the reduction soap film had originally owing to itself have the hydrophobicity position.

By these two kinds of polymers are cooperated with specific ratio, can make alveolar substance be creaminess, have the characteristic of easy to foaming degree to being flooded in towel.The contriver think this be because, because composition (C) nonionic polymkeric substance, the foam that the initial stage produces is soft and large, the effect of the stable vacuolar membrane that causes of (B) cation property copolymer causes being creaminess along with the cleaning process foam attenuates in addition.And because the effect of nonionic polymkeric substance, although foam is tiny, foam is also very soft and ductility good, the easy cleaning whole body.
