Method for affecting touch
Leave-on compositions to be applied to the skin, which after five minutes post-application provides an improved low residue level, where the composition includes an emulsifier having a particular HLB value and an emollient present in a weight amount that is equal to or greater than the weight amount of the emulsifier.
1. A method of promoting affective and soothing touch by a caregiver to a child, comprising:
a. the caregiver dispensing a predetermined amount of a composition onto the caregiver's hand or fingers and/or the child's skin, the composition comprising an emulsifier having an HLB value of between about 4 and about 10; and an emollient, wherein said emollient is present in a weight amount that is equal to or greater than the weight amount of the emulsifier;
b. the caregiver using the caregiver's hand or fingers to apply the composition onto a selected surface of the child's skin for a period of time sufficient to apply the composition to a selected surface of the child's skin;
whereby the step of applying is performed at a stroking force of from about 0.2N to about 2.0N and/or at a velocity of from about 1 cm/s to about 10 cm/s;
wherein the composition comprises from about 0.20% to about 0.75% by weight of emulsifier, wherein said emulsifier is an olivate, wherein said olivate is a combination of cetearyl olivate and sorbitan olivate; an emollient isopropyl palmitate, wherein said isopropyl palmitate is present in a weight amount that is equal to or greater than the weight amount of the olivate; and cellulose powder, wherein the cellulose powder comprises regenerated cotton powder, wherein said regenerated cotton powder is present in an amount of about 0.1% to about 3.0% by weight of the composition, wherein said cellulose powder is dispersed throughout said composition.
2. The method of claim 1 , wherein the selected surface of the child's skin includes a region of skin in which there is hair present.
3. The method of claim 1 , wherein the step of applying the composition activates at least one c-tactile fiber in the selected surface of the child's skin.
4. The method of claim 3 , wherein activation of c-tactile fiber is demonstrated by at least one of: higher perception of pleasantness of the touch, lowered heart rate and increased relaxation, recording and measuring affective state by facial electromyography, and higher degree of behavioral engagement.
5. The method of claim 4 , wherein the higher degree of behavioral engagement comprises at least one period of longer individual gaze by the child at the stroking stimulus.
6. The method of claim 1 , wherein said composition is free of emulsifier having an HLB value of below 4 or above 10.
