Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of daily chemical products, and particularly relates to a cleansing and makeup removing jelly and a preparation method thereof. BACKGROUND

[0002] Currently, there are products on the market that can be used for both cleansing and makeup removal, but they all have the problems of less foam, weak makeup removal ability, and a rough and slippery skin feel after washing. There is a lack of a comprehensive cleansing and makeup removal product. If makeup is not removed completely and there is residual accumulation, the pores on the face will become large, the number of blackheads will increase, and the skin will become rough and yellow, clogging the pores, causing the skin to become red, inflamed, and long-pimpled, and inflammation will intensify, leading to facial aging. Excessive cleaning will cause the skin to be out of balance, the skin's lipids to be excessively lost, the skin barrier to be damaged, and the skin to be sensitive and have large pores. Therefore, a cleansing and makeup removal product is needed that can effectively remove makeup and sunscreen from the face without excessively cleaning the skin, maintaining the water and oil balance of the face, and presenting a healthy state of the skin.

[0003] Some people with dry, neutral, and sensitive skin need a cleansing jelly with good moisturizing effect, but most current cleansing jellies only have a cleansing effect and do not have the functions of purifying the skin and repairing sensitive skin. Modern women mostly wear makeup, and if the cleansing jelly used does not have good makeup removal effect, it will also affect the skin.

[0004] CN105832649A discloses a green bean enzyme skin cleansing jelly, which comprises the following components in percentage by weight: alkyl alcohol acrylate cross-linked polymer 0.8-1.2, lactic acid bacteria or green bean seed extract fermentation product filtrate 20-30, EDTA di-nano 0.05-0.1, aloe vera leaf extract 0.3-0.5, trehalose 1-3, 30% sodium lauroyl methylchitosan 2-6, jojoba wax PEG-120 ester 1-3, butanediol 1-5, Usnea extract 0.01-0.05, chlorphenesin 0.1-0.3, podocarpus extract 0.5-2, 1.3 propylene glycol 0.8-1.5, PEG-40 hydrogenated castor oil 1-4, olive oil PEG-7 ester 1-4, cocoglycoside 1-5, water 2-4, chitosan monosuccinamide 2-5, 10% potassium hydroxide, 5% traditional Chinese medicine extract, and the balance. The green bean enzyme skin cleansing jelly is mild, can clean and remove makeup, repair sensitive skin, purify the skin, and treat and repair acne.

[0005] CN106474015A discloses a long-acting moisturizing functional cleansing jelly, which is composed of the following raw materials in parts by weight: water 85-90 parts by weight, cleaning agent 6-10 parts by weight, thickening agent 1-3 parts by weight, humectant 1-2 parts by weight, emulsifier 0.3-0.8 parts by weight, skin conditioner 0.15-0.25 parts by weight, plant ingredient extract 0.15-0.25 parts by weight, chelating agent 0.03-0.08 parts by weight, colorant 0.005-0.015 parts by weight. The cleansing jelly contains dragon head bamboo extract and other plant ingredient extracts, and the fine and abundant foam gently and thoroughly cleans the facial skin from the inside out, making the skin feel comfortable and healthy, and instantly refreshed. The cleansing jelly can clean and supplement the moisture of dry skin at the same time, and is a long-acting moisturizing functional skin care product.

[0006] The viscosity of the amino acid surfactant changes greatly with temperature, and after storage for a period of time, the product may have defects such as thickening and watering.

[0007] CN111514062A discloses a liquid crystal type amino acid facial cleanser, and the components and the weight percentage of each component are as follows: sodium cocoyl glycinate 15-18 parts, sodium lauroyl sarcosinate / sodium lauroyl glutamate 20-25 parts, modified corn starch 3-5 parts, glycerol 15-18 parts, acrylic copolymer 2.5-4 parts, stearic acid 1.5-2 parts, sodium citrate 3-5 parts, pearl double ester 2-2.5 parts, liquid crystal thickening agent (sodium laurate taurine / sodium laurate / modified corn starch / myristic acid) 22-25 parts, phenoxyethanol 0.3-0.6 parts, and the rest is water. The liquid crystal type amino acid facial cleanser uses phenoxyethanol as a preservative, does not add fragrance and pigment, is mild, does not cause skin allergy and irritation, the formula has weak acidity, the foam is fine and abundant and easy to wash, and the cleaning effect is good. The formula process is simple and convenient for production.
