Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] FIG. 1 is a flow chart for producing PVA particles in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] With reference to FIG. 1, a first embodiment for producing cleaning cream containing PVA (Polyvinyl Acetate) particles of the present invention comprises steps of:

[0013] blending PVA particles and glycerine by a high speed mixer letting PVA particles being completely soaked with the glycerine, wherein the PVA particles contain PVA 5095 wt % and glycerine 0.550 wt % after soaking with the glycerine;

[0014] adding a functional material 0.54.5 wt % while blending;

[0015] grinding the PVA particles to smooth its surfaces; and mixing the PVA particles with a cleaning cream which the moisture content of the cleaning cream is at the range of 0.123 wt % and the cleaning cream contained at least a surfactant. The PVA particles mixing in the cleaning cream are preferred at range of 0.55 wt %.

[0016] Particle size of unprocessed PVA particle is around 100 mesh (150 m) which is incredibly hard and having sharp edges on its surface. After soaking with the glycerine, the particle size of PVA particles will increase to 7080 mesh (180220 m) and become much softer and smoother. This may provide comfort and better quality when applied to human body without causing any scratch or even injury.

[0017] The functional material as mentioned above may be but not limited to colorant, fragrant or essence. The cleaning cream of the present invention may be a cream, gel or paste. The surfactant in the cleaning cream may be but not limited to anionic surfactant, cationic surfactant, nonionic surfactant or ampholytic surfactant. Beside the surfactant, the cleaning cream may further contain additives as desired like chelating agent or preservative.

[0018] PVA is water soluble polymer. It will be dissolved or degraded in an environment contained great amount of water or moisture. In order to keep the PVA particles as complete particle form in the cleaning cream contained with water/moisture, the molecular weight of PVA of the present invention is preferred at the range of 110,000120,000 D (Dalton, D). As the molecular weight increased, the viscosity of PVA becomes higher and the water soluble property of PVA otherwise becomes lower. Hence, the viscosity, water-solubility and texture of PVA in the present invention may be controlled by using PVA with different molecular weights.

[0019] On the other hand, PVA with molecular weight at the range of 110,000120,000 D has better absorption ability to the glycerine which will end up with products with excellent quality and texture. The PVA particles of the present invention are able to maintain stable in the cleaning cream. When applied to human body, the PVA particles of the present invention are able to remove dead skin or teeth tartar without causing any scratch or injury. After draining to the sewer, the PVA particles will be dissolved or degraded by water which won't cause any damage or contamination to the ocean or the environment.

[0020] The cleaning products include kinds of preparations with different use methods. To apply directly on the skin or teeth and to apply by forming foam with adding a little bit of water are two most commonly use methods. The foam will contain water/moisture up to 5060 wt % which is higher than the cleaning cream of the present invention (23 wt %). The PVA particles of the present invention is still able to keep as complete particle form for at least 25 minutes to maintain its function. This may credit to the molecular weight of the PVA as mentioned above.

[0021] Main materials of the present invention only contain PVA and glycerine. These two materials are considered eco-friendly and safe to human body. It will also cause no harm to sea creatures or animals even being discharge to the ocean or environment.

[0022] With reference to below chart 1, samples of the present invention are provided after produced by above mentioned producing method. Chart 1 shows the content of glycerine in PVA particles, expanded size of PVA particles and appearance and texture of PVA particles after soaking with glycerine.

TABLE-US-00001 CHART 1 Glycerine Expanded size (wt %) (times) Appearance and texture Sample 1 20 4 times bigger Appearance: round, small than unprocessed Texture: hard PVA particles Application: Suitable for the cleaning cream like toothpaste or exfoliating product for foot. Sample 2 30 6 times bigger Appearance: round, moderate than unprocessed Texture: moderate PVA particles Application: Suitable for most cleaning creams. Sample 3 35 7 times bigger Appearance: round, big than unprocessed Texture: soft PVA particles Application: Suitable for the cleaning cream like exfoliating or whitening products for face or body.

[0023] According to description above, PVA particles of the present invention are able to stay as particle form in the cleaning cream that contained certain quantity of water. The present invention may provide excellent exfoliation and whitening functions when applied to human body. After draining into sewers with contaminated water, the PVA particles of the present invention will be degraded or dissolved by great amount of water which may solve the problems that conventional PE or PP made plastic particles are not degradable in the environment.

[0024] The PVA particles of the present invention may be manufactured by conventional plastic processing process. The cost will be low and the particle size will be easily controlled by the present invention.
