Embodiments described herein relate generally to apparatus, methods and systems for low energy processing of consumer personal hygiene products (PHPs) and formulations of the same. In some embodiments, a method of manufacturing a consumer PHP comprises combining a first material and second material at room temperature to form a first mixture, mixing the first mixture at room temperature, adding a third material at room temperature to form a second mixture; mixing the second mixture at room temperature, adding a fourth material at room temperature to form a third mixture; and mixing the third mixture at room temperature. In some embodiments, the third material and the fourth material can be mixed to form the second mixture and the first mixture and second mixture can be combined to form the third mixture. In some embodiments, the mixing can be accomplished using a propeller mixer. In some embodiments, the propeller mixer can be rotated at a speed of greater than about 200 rpm during at least one of the mixing steps. In some embodiments, the pH of the third mixture can be adjusted to between about 4.5 and about 6.5 using an acidifier. In some embodiments, the viscosity of the third mixture can be adjusted to between about 100 cP and about 25,000 cP using a thickener.

A method for preparing a cosmetic component is provided which includes applying a layer of a dry cosmetic ingredient between a pair of fibrous sheets obtained by electrospinning one or more polymeric materials at least one of which is capable of cold flow under pressure. Sufficient pressure is then applied to the layers of fibrous sheets to cause cold flow of at least some of the polymeric material such that at least parts of the fibrous sheets bond with each other and entrap the cosmetic ingredient in position between them and prevent it from migrating between the sheets during further processing or handling.
