Abstract

An aqueous or hydroalcoholic, aerosol or non-aerosol hair styling aid or mousse composition containing a water soluble or dispersable fixative polymer in an amount from 1% to 40% by weight of the composition, a neutralizing agent in an amount from 0.1 to 10 wt %, a hydrocarbon based surfactant in an amount from 0.01% to 5% by weight, a salt from 0.01% to 10% by weight, alcohol from 10% to 90% by weight and water from 10% to 90% by weight of the composition. Additionally, aerosol compositions contain a liquified propellant gas from 5% to 60% by weight of the composition.

Description

BACKGROUND OF THE INVENTION

Regulations and laws designed to protect the environment, are leading to the production of hair care spray products which have lower volatile organic compounds (VOC) content than the current commercial products.

This invention relates to 55% VOC (and lower VOC) hair spray compositions that provide hold and feel properties similar to or better than that of the current 80% VOC hair sprays. The performance characteristics of hair sprays suffer as the VOC level is reduced from 80% to 55% in the product. Therefore, maintaining or improving the performance characteristics of 80% VOC product in 55% VOC (and lower VOC) products affords hairspray products which have good characteristics and are more environmentally friendly.

SUMMARY OF THE INVENTION

As noted above, the performance characteristics of hair sprays generally suffer as the VOC level is reduced from 80% to 55% in the product. The purpose of this invention is to at least maintain, if not improve, the performance characteristics of the 80% VOC system in the 55% VOC product.

In the present invention, the deterioration of the spray characteristics of a hydroalcoholic solution containing the hair spray resin which occurred as the alcohol content was reduced from 80 to 55% was offset by incorporation of a unique combination of hydrocarbon based surfactants and an organic salt. The same benefit can be obtained in aqueous systems.

In the present invention, the hydrocarbon surfactant is selected from the group consisting of: sodium dioctyl sulfo succinate, sodium dodecyl sulfate, cocoamidopropyl betaine, and sodium laureth sulfate, and the like.

In the present invention, the organic salt is selected from the group consisting of: sodium benzoate, magnesium acetate, and the like.

The invention relates to an aqueous or hydroalcoholic, non-aerosol or aerosol hair spray composition containing a water soluble or dispersable fixative polymer in an amount from about 1% to about 40% by weight of the composition, a neutralizing agent in an amount from about 0.1 to about 10 wt %, a hydrocarbon based surfactant in an amount from about 0.01% to about 5% by weight, a salt from about 0.01% to about 10% by weight, alcohol from about 10% to about 90% by weight, a propellant from about 0 to about 80% by weight, and water from about 10% to about 90% by weight of the composition.

Definitions

Dynamic Surface Tension

A test liquid in a typical surface tension experiment is static and any surface active material would be in equilibrium. In reality, spraying and subsequent wet out on hair are both dynamic processes and are affected by the surface tension of the formulation. Any materials that are surface active need time to migrate to and organize themselves at the air-liquid interface in order to effectively lower the surface tension. Any difference in perceived static versus dynamic surface tension could result in less than optimum performance. As described below, the faster the surface tension of a composition equilibrates, the better are its hairspray characteristics.

The dynamic surface tension experiment is typically conducted using a maximum bubble pressure method. This method is based on recording the pressure required to form bubbles at a given rate/ frequency in a test liquid. The surface tension is then calculated based on the measured pressure. The results are typically expressed in terms of dynamic surface tension against the surface age. Surface age is the time elapsed between the bubble formation and detachment of the bubble.

A surface age of about 10 msec is the time frame of interest for drop formation in spray process. The liquids used in hair spray applications generally reach equilibrium within 1000 msec (surface age of 1 sec.). To obtain good spray properties, the difference between the surface tension obtained at very short time scales (ex: 10 msec) and the equilibrium surface tension (obtained for example at 1000 sec or higher) should be as small as possible.

We have chosen the difference in surface tension obtained at a surface age of about 10 msec and that obtained at a surface age of about 1500 msec (Δ _10-1500) as the criterion for comparing the performance of different hair spray solutions.
