The invention relates to bars which provide specific combinations and amounts of nonionic polymer, polyol, short chain fatty acid and solid particles. These specific combinations provide both improved sensory and improved fragrance delivery.

The present invention discloses a method of preparing a bactericidal, fungicidal and anti-allergenic Zanthoxylum schinifolium skin care soap, wherein the bactericidal, fungicidal and anti-allergenic Zanthoxylum schinifolium skin care soap comprises the following components based on percentage by weight: Component A: Zanthoxylum schinifolium seed oil 15.0-21.0%, propylene glycol 12.0-17.0%, glycerin 6.0-11.0%, Component B: deionized water 5.0-8.0%, sodium alkyl ether sulfate AES 8.0-12.0%, Component C: lauric acid 5.0-8.0%, stearic acid 11.0-16.0%, Component D: 98% NaOH 2.5-4.5%, deionized water balance, Component E: Zanthoxylum schinifolium essential oil 0.3-0.8%. The skin care soap of the present invention is pale yellow and translucent, has good stability, provides great aroma and rich foam, and can nourish the skin and sterilize effectively.

The invention relates to bars which provide specific combinations and amounts of nonionic polymer, polyol, short chain fatty acid and solid particles. These specific combinations provide both improved sensory and improved fragrance delivery.

The use of (i) water, (ii) sugar, sorbitol or a mixture thereof and (iii) humectant is used for improving heat transfer to a soap.

Solid cleansing compositions and methods for the same are disclosed herein. The solid cleansing composition may include a soap and a plant oil. The plant oil may include flaxseed oil, and may be present in an amount effective to maintain or increase hydration of skin, inhibit inflammation of skin, deodorize skin, inhibit irritation of skin, or combinations thereof.

A method and material for 3D printing objects containing heat-sensitive molecules are disclosed. The composition consists of a water-saturated, polar thermoplastic polymer, such as highly hydrolyzed polyvinyl alcohol (PVA), into which functional moleculesproteins, peptides, pharmaceuticals, fragrances, or living cellsare dispersed. The polymer is first hydrated to form a gel, extruded and cut into pellets, then partially dried through a multi-stage dehydration process that leaves a moisture-rich core and a dry outer shell. During extrusion at typical FDM nozzle temperatures (200 C.), entrapped water within the material vaporizes at 100 C., providing in situ evaporative cooling and maintaining the temperature of the functional molecules below their degradation point. The process enables additive manufacturing of structurally sound objects that preserve the activity of heat-sensitive additives, opening new applications for 3D-printed consumables, pharmaceuticals, and bio-functional components.
