Problems solved by technology
However, changing one or more characteristic ingredients of an aerosol hairspray product can be challenging as their interrelationships affect product performance
For example, the use of different propellants may lead to an unacceptable reduction in packaging operating pressure, which will lead to increased wetting of the product upon application, longer drying times, increased particle size distribution and thus unsatisfactory retention.

[0029] Definition and Overview
[0030] In all embodiments of the present invention, unless otherwise specified, all percentages are by weight of the total composition (or formulation). All ratios are by weight unless specifically stated otherwise. All ranges are inclusive and combinable. The number of significant figures expresses neither a limitation on the quantity indicated nor a limitation on the precision of the measurement. Unless specifically stated otherwise, all quantities are understood to be modified by the word "about". Unless otherwise indicated, all measurements are understood to be made at 25°C and at ambient conditions, where "ambient conditions" means conditions at about 1 atmosphere of pressure and about 50% relative humidity. All such weights as they pertain to listed ingredients are based on the active level and do not include carriers or by-products that may be included in commercially available materials, unless otherwise specified. The unit "g" me...
