56 results about "Hemp oil" patented technology

Hemp oil (hemp seed oil or hempseed oil) is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the Cannabis flower.

Penetration enhancing agent and method of its production from the hemp seeds

The conveying and absorption agent, preferably for the active substances of the pharmaceutical, dietetic, and cosmetic preparations, consists of the extract from the hemp seeds, obtained by action of carbon dioxide. Advantageously, the extract is a component of the fat or wax base of the pharmaceutical or cosmetic preparation, preferably composed of the propolis relieved of its pollen contents. According to the method of production of the conveying and absorption agent from the hemp seeds for the active substances of the pharmaceutical, dietetic, and cosmetic preparations, the hemp seeds are ground down to hemp flour, being then pressure-extracted with carbon dioxide to the hemp oil. The hemp seeds are ground down to fine-grain flour, which is then powered into the extraction cartridges that are inserted into the extractor. Extractor is then closed and the carbon dioxide is then driven into it at the temperature between 35° C.-45° C. and the pressure between 25 MPa and 35 MPa, advantageously 40° C. and pressure 29 MPa. With the hemp oil extraction process slowed down, the carbon dioxide pressure in the extractor is reduced down to the ambient atmospheric pressure value and the hemp oil is separated from the carbon dioxide which is subsequently led away from the extractor to the reserve tank, where it will be stored in its supercritical condition. For removal of chlorophyll and waxes, 2%-35% in weight of the crushed silicon sand is mixed into the hemp oil extracted. Following the surface absorption, the crushed silicon sand is filtered out.

Blackhead removing essence containing industrial cannabidiol and preparation method thereof

The invention discloses blackhead removing essence containing industrial cannabidiol and a preparation method thereof. The blackhead removing essence is prepared from the following raw materials: a hemp leaf extract, hemp seed oil, a medicinal phellinus igniarius extract, hamamelis virginiana flower water, nicotinamide, salicylic acid, an anti-aging additive, a face-thinning additive, a turmeric root extract and a reinforcing additive. The invention relates to the technical field of daily chemical products. According to the blackhead removing essence containing industrial cannabidiol and the preparation method thereof, blackheads are removed by three effects of shrinking pores, tightening skin and brightening and beautifying skin, granular blackheads at hair follicle parts are directly dissolved into loose powder, the pores are synchronously shrunk and the blackheads are discharged out of epidermis, pores are shrunk, grease is regulated, growth of the blackheads is inhibited, and anti-aging and face-thinning functions are added; and a coix seed extract is utilized to further enhance the blackhead removing effect and improve the skin whitening effect, so that the aim of radically treating the blackheads is achieved, and the using effect is better.

Preparation process for hemp oil

The invention discloses a preparation process for hemp oil. The hemp seeds are subjected to three-stage screening the hemp seeds are separated from impurities; the selected hemp seeds are stir-fried;a squeezing machine is used for squeezing the hemp seeds at low temperature; the hempseeds are squeezed into hemp oil; the hemp oil is separated from the hemp oil residues; a precipitation box is usedfor carrying out three-stage precipitation on the hemp oil; the precipitated hemp oil is conveyed to a water refining device; the hemp oil subjected to water refining is conveyed to an alkali refining device; the hemp oil subjected to alkali refining is conveyed to a water washing device to be repeatedly washed for three times through a washing device; the washed hemp oil is conveyed to a heatingdevice, the heating device removes moisture contained in the hemp oil, the dehydrated hemp oil is conveyed to a filtering device, and an activated carbon layer arranged on the filtering device removes residual impurities in the hemp oil so that the problems that the hemp seeds are difficult to stir-fry uniformly, and the oil yield of the hemp seeds is relatively low are solved; and the problems that the impurities in the squeezed hemp oil are difficult to remove and thus the hemp oil is poor in taste can be solved.

Method for extracting and purifying broad-spectrum hemp oil from hemp

The invention discloses a method for extracting and purifying broad-spectrum hemp oil from hemp, belongs to the field of chemical extraction and purification. The method comprises the following stepsof: harvesting, drying and crushing hemp flowers and leaves to obtain a clean material for later use; carrying out continuous countercurrent extraction on the clean material by adopting an ethanol solution with a concentration of 60-95% to obtain a crude extract; concentrating the crude extract under reduced pressure to obtain an extract, heating the extract to 130-150 DEG C, and carrying out a decarboxylation reaction for 1-2 hours to obtain a decarboxylated solution; carrying out short-path molecular distillation on the decarboxylated solution, and collecting distillation products with different boiling points to obtain crude oil; winterizing the crude oil, and carrying out filter pressing to remove wax so as to obtain filtrate; carrying out column chromatographic purification on the filtrate by using an ethanol solution to obtain a chromatographic solution; and concentrating the chromatographic solution to an oil form so as to obtain the broad-spectrum hemp oil. The method has the advantages that an extraction rate is high, the solvent can be recycled, the total amount of cannabinoid is high, and tetrahydrocannabinol (THC) is hardly contained.
