Description
Technical field:
The present invention relates to a kind of Cleasing compositions of stiff.In detail, relate in a kind of personal-care supplies field the Cleasing compositions for the stiff of skin, eyes, tooth and hair cleaning purposes.
Background technology:
As the Cleasing compositions of skin, eyes, tooth and hair decontamination and clean purposes conventionally contain various take clean and surfactant that decontamination is object.In order further to improve foaming and the cleaning effect of cleanser compositions, also tend to add more than a kind of surfactant.Conventionally in Cleasing compositions, also can use a certain amount of solvent, especially make water, or the mixed solvent of water and polyhydric alcohol dissolves surfactant and active component, product is more easily used.In order to reach the usability of Cleasing compositions in personal-care supplies field, also can add more than a kind of beauty treatment and clean adjuvant, although the selectivity of beauty treatment and clean adjuvant adds and be nonessential.
Cleasing compositions only clean and decontamination is inadequate, and consumer wishes to buy the Cleasing compositions of outward appearance stiff.Consumer thinks that the Cleasing compositions of stiff is the product that usefulness is good, working substance content is higher, and it is relieved and economical that consumer feels.Meanwhile, the Cleasing compositions of stiff can be installed in flexible pipe or similar packing container, and when opening soft tube cap, Cleasing compositions is unlikely to flow out as water.For manufacturer, the Cleasing compositions of stiff is conducive to reduce packing cost, easy to use and carry for consumers.
Most of traditional stiff Cleasing compositions is to use high-load fatty acid soaps as key component in the market, for example: that in the patent EP1166747 of L'oreal's application, describes take fatty acid soaps as key component " stable foaming mastic ".But the stiff Cleasing compositions that fatty acid soaps is key component has higher pH value (pH value is 9～11 conventionally), and they can cause part consumer to occur the phenomenon of skin allergy, redness, hair damages.From the angle of safety, Cleasing compositions and cake soap that the fatty acid soaps of take is master there is no essential progress from the angle of consumer's safety in utilization.
In this area, in order to produce pH value at the stiff Cleasing compositions of neutrality or faintly acid scope, in Cleasing compositions, generally use various association type thickening components to reach the object of product stiff.The main representative of association type thickening component is association type polymer, conventionally association type polymer be water-soluble polymer by a small amount of hydrophobic group of grafting, such as: alkyl chain, alkyl ethoxyquin base chain, form the polymer simultaneously with hydrophilic group and hydrophobic group.Mutual association due to hydrophobic group, under surfactant exists, hydrophobic group in the hydrophobic group of surfactant and association type polymer associates mutually, surfactant on association type polymer chain or near formation micelle (just as a string droplet on Aranea), this association is increased Cleasing compositions viscosity.This class association type polymer is for example: the hydrophilic ampholytic polymer of describing in the patent WO00/39176 of Bfgoodrich company application in personal care product as component to reach thickening and rheology modified object.
The shortcoming of the Cleasing compositions of use association type polymers compositions is very obvious, the Cleasing compositions of stiff tends to stick in skin and hair surface not easy to apply opening in use, and this Cleasing compositions is subject to variations in temperature and viscosity changes greatly, during winter, be fruit jelly shape, and summer is thin as the water.Especially use winter and be not easy to smear out, affect lather quickness and the foaming effect of Cleasing compositions.As Cleasing compositions lather quickness and foaming effect, it is another key factor of consumer evaluation's product quality.Therefore, consumer is to being used the Cleasing compositions of association type thickening component feel dissatisfied and do not accept.
Summary of the invention:
The technical problem to be solved in the present invention is to overcome deficiency of the prior art, the Cleasing compositions of a kind of stiff of pH value within the scope of neutrality or faintly acid is provided, and this Cleasing compositions can keep viscosity stabilization under different temperature conditions, be easy to smear, bubble rapidly and foam quality good.
Present inventor, by after studying for a long time, realizes of the present invention by following technical measures.A Cleasing compositions for stiff, comprises following component (a), (b), (c) and (d) by weight percentage:

Effect and the mechanism of action of each component of Cleasing compositions of the present invention are as follows:
Generally, the concentration along with surfactant in the Cleasing compositions that contains surfactant and water increases, and surfactant is changed to rod-shaped micelle by globular micelle, forms the certain viscosity of Cleasing compositions.But rod-shaped micelle cannot form the stiff Cleasing compositions of " toothpaste-like " of required having " good rheological characteristic ".
Surfactant and solvent have played the object of clean and decontamination in cleanser compositions.
And long-chain fat acyl neutral amino acid ester and fats compound are that induced surface activating agent and solvent formed " rod-shaped micelle " required in opposite directions " liquid crystalline phase " change in the effect of Cleasing compositions, thereby Cleasing compositions is become have the stiff Cleasing compositions of " toothpaste-like " of " good rheological characteristic ".
Above-mentioned " good rheological characteristic " refers to have the apparent viscosity of stiff and have good thixotropic fluid, and thixotropy shows as and is easy to smear and bubbles rapidly in Cleasing compositions is used.
Above-mentioned " toothpaste-like " refers to that viscosity is greater than 10000cps (centipoise).
Above-mentioned " micellar phase " and the elaboration of " liquid crystalline phase " are that this area scientific research technical staff is familiar with, and annotation is found in < < surface of base activating agent > > teaching material in detail.
Production technology of the present invention is the general methods of those skilled in the art, be summarized as follows: in the container of stirrer paddle is housed, (stirrer paddle is anchor formula, frame, screw-pushing type) container with chuck or metal coil pipe heating and cooling system, first add solvent (water normally, the mixed solvents such as polyhydric alcohol), open heating, container is slowly heated to 60 ℃ of left and right, then add successively other various components (except volatile component, antiseptic and essence are outer), in stirring, be slowly heated to 80 ℃ simultaneously up and down, open and stir and be incubated at 80 ℃ up and down, maintain three hours.In confirmation, fully stir and reach after index of correlation, opening cooling system and begin to cool down, being cooled to 40 ℃ of left and right and adding again volatile component, antiseptic and essence, after fully mixing, emitting material body.
