ABSTRACT: TITLE: Scalp Shielding Formulations to prevent chemical penetration, burning, skin colour staining and irritation associated to process of on-skin chemical hair colouring, lightening or bleaching preparations. Technical Field: On-skin mammal hair colouring, lightening or bleaching services. Background: [0001] Hair colouring, lightening or bleaching applications designed to bring an effect of changing the natural colour state of human hair is a common practice done in professional salon environments and home environments all over the world on a daily basis. These processes use chemical preparations of an alkaline pH nature to affect a major part of the colour transformation. [0002] The chemical process used to achieve the colour lightening and or deposit of pigment is an oxidation process and these colouring chemicals often have a negative effect on the comfort of the recipient, the condition of affected skin and often result in unwanted and unsightly colour staining of the skin, chemical irritation and skin inflammation. Despite a good professional Hairdressing Salon common knowledge and many well documented examples of irritation and unsightly skin staining caused by alkaline based colour preparations only a few formulations have been made to assist in this area. [0003] Of these formulations mentioned above, examination of these preparations reveals that they are either petroleum jelly based barriers to aqueous preparations or are derived from combinations of ingredients such as polysorbates, silicone oils or natural oils and maintain a liquid form during the colour process allowing for some penetration of the colour chemicals through these preparations into the skin through the protective medium. [0004] Additionally, none of these known formulations address the free radical singlet oxygen damage created by the use of Hydrogen Peroxide within the alkaline based colour and bleaching preparations.
