The present disclosure generally relates to personal care and/or cleansing compositions and wipes. More particularly, the disclosure relates to single phase compositions and wipes for cleansing the skin or hair of a user without the use of a surfactant. To achieve the cleansing effect, a modified sorbitan siloxane is incorporated into the compositions and wipes. Additionally, the modified sorbitan siloxane containing compositions may provide for a perceivable aesthetic feel to the skin or hair.

Wipes have been used in the personal care industry for numerous years, and generally comprise a low surfactant, high water base for cleaning bodily fluids or wiping up menses. In recent years, however, consumers have begun demanding more out of personal care products, including wipes. For example, various wipes have come into the market containing ingredients for soothing skin or containing actives for disinfecting surfaces. Another example of a desired wipe property is the delivery of perceivable consumer aesthetics and/or moisturization. However, many skin benefit agents that provide desired aesthetics and/or moisturization properties are hydrophobic. It has thus proven to be difficult, given the generally high amounts of water and small amounts of surfactants present in typical wet wipe solutions, to incorporate such agents into wipes.

Iodide salts of dimethylaminoethanol fatty acid esters with bacteriostatic, mycostatic, yeaststatic and/or microbicide activity for use in cleansing or purifying formulations
European Patent EP1892236
Publication Date: Jan. 18, 2012
Assignee: Scharper S.p.A.

The present invention relates to agents with bacteriostatic, mycostatic and yeaststatic and/or microbicide activity to be used in purifying or cleansing formulations for the skin, mucosa and ear, and to a process for preparing said agents.

The applicant has now prepared new salts of dimethylaminoethanol fatty acid esters of general formula in which R is a C6-C16 linear or branched alkyl radical, X- = l-, and which, as well as being biocompatible, has bacteriostatic, mycostatic, yeaststatic and/or microbicide activity. In addition to have said properties, these salts are sufficiently water soluble with surfactant properties so that said aqueous solutions, which contain them, form a substantial amount of foam. These salts can hence be advantageously used in purifying or cleansing formulations of the skin, mucosa and the auricle. Therefore a further aspect of the present invention are the said cleansing or sanitizing formulations for the skin, mucosa or ear comprising at least one of said agents with bacteriostatic, mycostatic, yeaststatic and/or microbicide activity.
