Abstract

The invention discloses a moisturizing aloe vera gel and a preparation method thereof. The moisturizing aloe vera gel comprises the following raw materials in parts by weight: 80-140 parts of water, 50-80 parts of arbutin, 45-65 parts of hydrogenated castor oil, 60-70 parts of olive-pomace oil, 30-60 parts of tocopherol, 20-50 parts of carbomer, 25-55 parts of triethanolamine, 15-35 parts of sorbitan monooleate, 20-40 parts of allantoin, 10-20 parts of an aloe vera gel noumenon, 15-45 parts of methyl chloride isothiazolinone, 40-70 parts of low molecular weight chitosan and 35-55 parts of polyethylene glycol. The preparation method comprises the following steps: heating water, arbutin, hydrogenated castor oil, olive-pomace oil, tocopherol, carbomer, triethanolamine, sorbitan monooleate, allantoin, methyl chloride isothiazolinone, low molecular weight chitosan and polyethylene glycol to 40-50 DEG C, adding the aloe vera gel noumenon while cooling to 30-40 DEG C, and carrying out uniform stirring. The moisturizing aloe vera gel provided by the invention has the advantages that the water content can be kept unchanged for all day long and maintained at 46-47%.

Description

technical field [0001] The invention relates to a moisturizing aloe vera gel and a preparation method thereof. Background technique [0002] Aloe vera gel has the functions of activating cell vitality, delaying skin aging, astringent and toning the skin. It can also anti-inflammatory and sterilize, inhibit inflammation, drain secretions, promote local metabolism, moisturize the skin, prevent keratosis, astringe sores, promote cell regeneration, reduce or avoid scars; from Chinese medicine, aloe vera has the effect of clearing away heat and detoxifying. It is a very suitable medicine for external use. It can prevent skin inflammation and allergies, bacterial growth, promote cell metabolism and skin regeneration, relieve pain and itching, and is effective for acne, acne, allergies, and redness. However, the moisturizing effect of aloe vera gel is not good, and it is quickly absorbed by the skin after use, and the skin surface becomes tight and uncomfortable after drying....
