80 ° c . for 10 to 15 minutes . in a separate vessel , the oil phase components were added . light mixing of the batch was performed with heating in a water bath to 75 - 77 ° c . the water reactor was maintained at 60 - 65 ° c . and slow addition occurred for glycerin , titanium dioxide and triethanolamine . continuous mixing was done until the aqueous system was uniform . very slowly the oil phase was added to the water phase at 75 - 77 ° c . under moderate mixing . after full emulsification , the batch was agitated for a further 5 minutes . thereupon the resultant emulsion was homogenized using an arde barenco ® apparatus for 20 - 30 seconds at 35 %. the resultant system was then topped with further deionized water . cooling then began with a large sweep ( 50 rpm ) mixer . preservatives glydant plus ® and dmdm hydantoin were then added with the batch held at 50 - 55 ° c . thereafter a slurry of ganzpearl gmp 0820 ® in the silicone oils were added to the batch . at a temperature of 45 - 50 ° c ., the fragrance was charged to the reactor . heating was then discontinued and mixing was stopped when the temperature reached 38 - 40 ° c . the finished cosmetic composition was then charged into a conair hld31 ® lotion dispenser . herein experiments are reported which determine the effect of temperature on the physical properties of a base lotion as a function of added structurant . the experiments utilized example 1 as a base lotion except that veegum ® ( magnesium aluminum silicate ) was substituted at 1 % with other traditional thickeners . test procedure involved measuring the viscosity at a shear stress of 20 pascals between the temperature of 32 ° and 48 ° c . shear stress was chosen because it represents the force of gravity . the two temperature range limits were selected because they represent the average skin surface temperature and average temperature of a lotion dispensed from a heated lotion delivery device . table 2 reports the percentage change in viscosity between the aforementioned skin temperature and that of the dispensed heated composition . the results as recorded in table 2 reveal that veegum ® not only retains viscosity at elevated temperatures but even provides for a significant increase in that viscosity . by contrast , the other structurants showed a decrease in viscosity upon reaching higher temperature . the results demonstrate the effectiveness of magnesium aluminum silicate for use with the heated lotion device of the present invention . the results from example 2 reveal what occurs concerning flowability of a composition as temperature increases . further experiments herein demonstrate the effect of structurants on the composition after it has been dispensed and becomes cold . yield point values were obtained to understand the latter phenomenon . the same formulations were employed as in example 2 . yield point is the amount of force , or shear stress , necessary to initiate flow . a controlled stress rheometer ( ta instrument ar 2000 ) was used for the test . the ar 2000 is a type of instrument that enables the stress to increase from a point below the yield stress , capturing the moment when the material starts to flow . the procedure is done at 25 ° c . using a 4 cm 2 % stainless steel cone . stress is ramped from 0 . 0 to 50 pascals in two minutes . the ramp is stopped when there is a strain value of 20 ( dimensionless ). this indicates that the product has started to flow . a computer is utilized to determine the amount of stress or yield point in pascals . table 3 reports the results . the results indicate that both veegum ® and volclay ® nf are the best structurants for stability purposes . viscosity changes only minimally as temperature increases by 20 °. by contrast , carbopol ® 934 ( crosslinked polyacrylate ), disteareth - 100 ipdi ( ethoxylated urethane ) and hydroxypropyl methylcellulose all exhibited significant double digit declines in the yield point .
