In one embodiment, in thickener blend composition, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:20 to 20:1.In a preferred embodiment, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:10 to 10:1.In a preferred embodiment, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:6 to 6:1.In preferred embodiment, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:2 to 2:1.In most preferred embodiments, the weight ratio of described Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:1.
Carrier can be any cosmetic field acceptable carrier.Such as, carrier can be aqueous carrier, such as water, comprises distilled water and deionized water.
Thickener blend composition of the present invention can join in cosmetics as functional additive and use.Therefore, the invention still further relates to the application of the thickener blend composition comprising 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers and Scleroglucan in cosmetics.The cosmetics comprising thickener blend composition of the present invention can obtain the product of viscosity higher when lower thickening agent consumption.
Detailed description of the invention
Unless otherwise defined, all technology used herein and scientific terminology have the identical meanings that one skilled in the art of the present invention understand jointly.Although or any method that be equal to similar with described herein and material can be used for implementing or testing the present invention, described herein is preferred method and material.For object of the present invention, define following term below.
Term " about " used herein refers to compared with the quantity of reference product, level, numerical value, dimension, size or consumption, difference can up to 30%, 20% or 10% quantity, level, numerical value, dimension, size or consumption.Percentage composition used herein, except as otherwise noted, all by weight.
In full section description and claims, Unless Otherwise Requested, following word " comprises " and its variant " contains " and " comprising " is interpreted as meaning to comprise described entirety or step, or one group of overall or step, but do not get rid of other overall or step any, or other group overall or step.
According to the present invention, term " cosmetics " refers to smear, spray or other similar approach, intersperse among any position of human body surface, as skin, hair, refer to toenail, lips and teeth etc., to reach clean, maintenance, beauty treatment, modify and change outward appearance, or correction human scent, the chemical industrial product for the purpose of maintaining a good state or fine chemical product.
The present invention is based on following unexpected discovery: the compositions of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers can be worked in coordination with and be promoted viscosity; therefore said composition as thickening agent additive in cosmetics, can have superior thickening effect.
In compositions, the concentration of Scleroglucan is about 0.01-2 % by weight, and the concentration of 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 0.01-2 % by weight.In a preferred embodiment, in compositions, the concentration of Scleroglucan is 0.01-1 % by weight.In one embodiment, the concentration of Scleroglucan is 0.3-0.5 % by weight.In one embodiment, in compositions, the concentration of 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is 0.5-2 % by weight.
In other embodiments, in thickener blend composition, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:20 to 20:1.In a preferred embodiment, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:10 to 10:1.In preferred embodiment, the weight ratio of Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:2 to 2:1.In most preferred embodiments, the weight ratio of described Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers is about 1:1.
Scleroglucan is the thickening agent that a kind of thickening efficiency is lower, concentration 0.1%, 0.3%, and the viscosity of the aqueous solution of 0.5% is 0,0 and 380mPa.s respectively.Visible, under working concentration of the present invention, the thickening effect being used alone Scleroglucan is unsatisfactory.Surprisingly, when both combinationally use, there is collaborative thickening effect.In the solution of 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers, add Scleroglucan makes the viscosity of solution sharply raise, and both promptings have collaborative thickening effect.
The present invention propose first using Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers composite as thickener blend composition, there is collaborative thickening effect.Therefore, thickener blend composition of the present invention can join in cosmetics as additive.

Embodiment 1: Scleroglucan and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers synergistic thickening experiment
1. experiment material
Scleroglucan, commodity are called AMIGEL, purchased from AlbanMullerInternational company; 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers, commodity are called SepinovEMT-10, also can be described as EMT-10 in the present invention, purchased from French Seppic company; And deionized water.
2. experimental apparatus:
Fixing agitator IKARW20
Thermostat water bath Shanghai Yiheng Scientific Instruments Co., Ltd HWS28 type
Weigh balance METTLERTOLEDOPL602-S
Viscometer BROOKFIELDDV III ULTRA
3. experimental technique:
3.1 take appropriate Scleroglucan powder and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers powder
3.2 weigh deionized waters, are slowly sprinkled in deionized water when high-speed stirred by the mixture of Scleroglucan powder and 2-(Acryloyloxy)ethanol/sodium acryloyldimethyl taurate copolymers powder, stir
Scattered colloid is heated to 80 DEG C and keeps stirring 10 minutes by 3.3
3.4 are cooled to room temperature, carry out follow-up experiments of measuring
4. experimental result
Scleroglucan is the thickening agent that a thickening efficiency is lower, and under 0.1%, 0.3% and 0.5% concentration, the viscosity of aqueous solution is 0,0 and 380mPa.s respectively.Table 1 shows the viscosity of Scleroglucan under variable concentrations.
Table 1: be used alone Scleroglucan viscosity (mPa.s)
| Concentration % | 0.1 | 0.3 | 0.5 |
| Viscosity (mPa.s) | 0 | 0 | 380 |
But experiment finds, after Scleroglucan adds the aqueous solution of EMT-10, can significantly improve the viscosity of the aqueous solution of EMT-10, the viscosity that the degree of lifting itself has much larger than the Scleroglucan added.Result is as shown in table 2.
The viscosity (mPa.s) of the solution of table 2:EMT-10+ Scleroglucan
Experiment can be found out, the EMT-10 solution under variable concentrations, add the viscosity of the obvious improving product of the equal energy of Scleroglucan, and the amplitude increased is much larger than the due viscosity of these Scleroglucans itself, illustrates that these two thickening agents have synergistic thickening effect.
