Description

ATOMIZATIONS FOR HAIR WITH LOW CONTENT OF VOLATILE ORGANIC SOLVENT CONTAINING CELLULOSE ETHERIES FIELD OF THE INVENTION This invention relates to spray compositions or aerosol sprays for hair.

BACKGROUND OF THE INVENTION The two main types of hair sprays commercially available are hair sprays and aerosol sprays for hair. 7? Mbos usually contain solvents, polymeric resins and in some cases, surfactants and fragrances. Resin is the main ingredient responsible for curl retention properties that are characteristic of hair sprays. Alcohol is the predominant solvent in both types of sprays for hair. However, for environmental reasons, legislation has been passed in some states that restricts the amount of volatile organic compound (VOC) in aerosol products to 55% of the total base solvent. Thus, VOCs are removed from hair spray formulations until they reach the 55% level, this has been replaced with water for economy and for environmental reasons.

For the new hair spray formulations containing high levels of water, a polymeric resin which is soluble in the highly aqueous solvent base and which provides the combination properties of fast drying time and curl preservation is necessary. U.S. Patent Nos. 5,176,898; 5,326,555; 5,206,009; 5,126,124 and 5,182,098 disclose aqueous spray compositions for hair having VOC contents of less than 80% and containing polymeric resins containing a variety of vinyl copolymers.

The power of hair maintenance of the compositions of this invention has been evaluated by measuring the initial maintenance of the curl of the tufts sprayed with the compositions and the maintenance of the curl after storing the treated tufts at a relative humidity of 90% up to 6 hours, hereinafter referred to as "curl maintenance at high humidity". Preferably these compositions impart to the human hair an Initial Loop Maintenance and a High Moisture Curl Maintenance greater than about 15%, preferably greater than about 45%, and more preferably greater than about 75%.

The drying times observed with the sprays for the hair of this invention, from about 23 to 25 minutes, are comparable to those observed with hair sprays of similar formulations with polymers widely used in the industry. This invention is illustrated by means of the following examples, which are only exemplary and not intended to be limiting. All percentages, parts, etc., are by weight, unless otherwise indicated.

Evaluation methods Spray application for the hair: the spray used for the spray was a Seaquist Dispensing "Euromist", with an output of 160 mcl, 24-410, with a submerged tube of 0.15 cm (0.060 inches) (internal diameter) ) with 3 0.041 x 0.025 cm insert (0.016 x 0.010 inches). The target distance from the pumping nozzle to the center of the curled lock was 6 inches. Drying time: a model Sartorius moisture analyzer MA 30 was modified by the addition of a switch to deactivate the heater. Test samples were applied to 4-inch diameter aluminum trays for evaluation.

For a test, the tray was weighed and held vertical at the test site at a distance of approximately 15 cm (6 inches) from the spray bottle. Two or three strokes of the spray pump were carried out to provide a sample weighing approximately 0.240 g. The tray was immediately returned to the balance, and the lid was closed, automatically starting the drying test. The output of the moisture analyzer was coupled to a computer such that the drying speed curves were generated. The instrument was run in a fixed time mode, and the end point in the drying curve can be determined by observation. With the fixed time at 30 minutes, for most formulations the weight stabilized at approximately 5-10% of the initial weight of the sample. Three or more samples of each formulation were tested. The reported results are the time to reach 10% of the original weight.

Preservation of the initial ripple and conservation of the ripple at high humidity: the tested samples used to determine the conservation of the initial ripple and conservation of the ripple at high humidity were 2.0-2.05 g locks of 23 cms (9 inches) long brown virgin hair Half Caucasian European by DeMeo Brothers, Inc., New York New York. The tufts were assembled by joining the ends of the roots of a sample of two grams of hair with two strands of plastic tied, located approximately 0.95 and 2.5 cm (3/8 and one inch) from the ends of the root. A test monofilament of approximately 10 cm (4 inches) in length of 13.6 kg (30 Ib) was formed into a curl and inserted into the end of the tuft before being tied with the thread. The tufts were also secured by applying several drops of cyanoacrylate adhesive in the area of the strand. In the preparation for the tests, each strand was combed dry to remove unsafe hair and then moistened with running water. A 3 mL solution of ammonium lauryl sulfate in 10% solution in deionized water was applied to the lock with a syringe, and the lock was thoroughly massaged for approximately 30 seconds. The lock was rinsed in tap water, and then the washing and rinsing procedure was repeated. The washing procedure was followed by a 30 second rinse under a stream of deionized water. Each strand was then trimmed up to 18 cm (7 inches) below the lower moored thread. The hair was combed wet two or three times and then with a paper in the end rolled on a hair curler 1.6 cm (5/8 inches) in diameter. Eight strands were prepared for each test formulation. The locks were hung by their curls and left to dry overnight in a room with controlled atmosphere, at 23 ° C, and 50% relative humidity. In spray preparations, 8 curly, dry tufts were hung in a controlled atmosphere room at 23 ° C and 50% relative humidity in a test rack scaled in inches increments, and the reading on the lower moored wire scale was annotated . The curling iron and paper were removed and the initial length of the curl in the lower part of the lock was noted. The hair strand and the spray bottle containing the composition for evaluation were placed in a designated test site to fix the target distance between the spray head and the strand at 15 cm (6 inches). The lock was atomized with three pumping strokes on one side, then inverted and atomized again with three strokes on the wrong side. The lock was then returned to the test shelf and the total length of the loop was recorded at 2, 4, 6, 8 and 10 minutes until the initial conservation of the curl was determined. The test rack was then placed in a Spec Model LHU-112 Humidity Cabinet set at 26.7 ° C and 90% relative humidity. The readings of the total length of the curl were taken at intervals of 15 minutes, 30 minutes, 1, 2, 3, 4, 5, and 6 hours until determining the conservation of the ripple at high humidity.

Immediately upon completion of the test, the curls were transferred to the controlled atmosphere room 23 ° C, 50% relative humidity, and the feeling in the hands with respect to stickiness, rigidity and brittleness were measured subjectively. The conservation of the ripple (% CD), for initial and high humidity were calculated as follows: CD = 100 (L-Lt) / (L-L0) where L is the length of the tuft fully extended, 18 cm (7 inches), Lt is the length of the tuft at the time of the test, and Lc is the initial length of the tuft before atomizing. The data of percent of Rised Conservation to Elevate Humidity reported here are after 6 hours in a humidified cabinet. The data for the 8 ripples were calculated as above and the average of the results was reported. Viscosity: the viscosity was measured in a water bath at 25 ° C with a Brookfield viscometer Model LVDV-I- + equipped with a "UL" adapter for low viscosity fluids. The readings were after two minutes of rotation at 12 or 30 revolutions per minute. The measurements were made in duplicate.
