Description

A nourishing, moisturizing and lightening lotion and preparation method thereof

Technical Field

The invention relates to the field of cosmetics, and in particular to a nourishing, moisturizing and lightening skin lotion and a preparation method thereof.

Background Art

The water content in the skin determines whether the skin is delicate, moist and shiny. Emulsion is usually used after lotion. Its main function is to moisturize the skin and lock in moisture, thus maintaining the water content in the skin, thus achieving an excellent nourishing and brightening effect.

As people's living standards improve, the demand for skin care is also increasing. At present, the skin care effects of lotions on the market are not ideal. Ordinary lotions have poor moisturizing properties; lotions with high moisturizing properties are too greasy and have a poor feel; most lotions on the market have a single effect, focusing only on moisturizing without considering other effects, such as whitening, anti-oxidation, and wrinkle and anti-wrinkle; some lotions contain hydroxy acids (fruit acids), retinoic acid, kojic acid, arbutin and other raw materials, which have the effect of whitening and brightening the skin, but will cause certain irritation and have the risk of allergy, affecting the consumer's experience; lotions with plant extracts are safer, but the cost is higher, the extraction process is cumbersome, and more plant extracts will affect the physical and chemical stability of the lotion, making the lotion easy to stratify and become viscous.

In the prior art, a patent application document with application publication number CN110151650A discloses a red blood streak removing lotion containing a horse chestnut composite active ingredient and a preparation method thereof, wherein the lotion comprises the following components: carbomer, xanthan gum, polyacrylate crosspolymer-6/tert-butyl alcohol, sodium hyaluronate, polyethylene glycol-8, polydimethylsiloxane, caprylic/capric triglyceride, pentaerythritol tetraisostearate, coconut oil-caprylic acid ester/caprate, cetearyl alcohol, phytosteryl isostearate, panthenol, sodium heparin, tetrahydromethylpyrimidine carboxylic acid, essence, glycerin, glyceryl stearate SE, triethanolamine, 1,2-pentanediol, Dendrobium nobile stem extract, Angelica sinensis root extract, Verbena extract, seven root extract, wild peony extract, peony root extract, Hydroxyphenylpropionamide benzoic acid, ascorbyl palmitate, panthenol, aescin, Ruscus aconitifolia root extract, ammonium glycyrrhizinate, Centella asiatica leaf extract, hydrolyzed yeast protein, calendula extract. Although the lotion has the effect of improving the symptoms of facial red blood streaks and treating and relieving induced red blood streaks, it has average moisturizing properties and no whitening and antioxidant effects.

The patent application document of application publication number CN113648241A discloses a high moisturizing emulsion and a preparation method thereof, wherein the emulsion comprises the following components: water, allantoin, chelating agent, methylparaben, sodium hyaluronate, hydrolyzed sodium hyaluronate, peony seed oil, squalane, tocopheryl acetate, arginine, trehalose, palmitoyl pentapeptide-4, beta glucan, panthenol, serum protein, hydroxymethyl chitosan, ergothioneine, yeast/rice fermentation product filtrate, p-hydroxyacetophenone, disodium edetate, wild soybean seed extract, glycerol, acrylic acid (ester) class/vinyl isodecanoate cross-linked polymer, polyglyceryl-6 distearate, arachidyl alcohol, polyglyceryl-3 beeswax acid ester, polysorbate-20, sodium pyrrolidone carboxylate, bodhi tree extract. Although the emulsion has good moisture retention, its performance is single.

Therefore, there is a need for a lotion that has whitening, anti-oxidation, anti-wrinkle and light-line effects while maintaining moisturizing properties, and has a comfortable feel, safe ingredients, little skin irritation and is not easy to cause allergies.

Performance Testing Methods

1. Physical and chemical properties (cold stability, heat stability, appearance, pH)

(1) Direct pH measurement: For Examples 1-2, the pH value of the nourishing, moisturizing and brightening lotion was measured using QB/T2286-1997 "Moisturizing Lotion". The measured data are recorded in Table 1.

(2) Relative density: For Example 1-2, the relative density of the nourishing, moisturizing and lightening lotion was measured using a relative density determination method. The measured data are recorded in Table 1.

(3) Kinematic viscosity: For Example 1-2, the kinematic viscosity of the nourishing, moisturizing and brightening skin lotion was measured using QB/T2286-1997 "Skin Lotions". The measured data are recorded in Table 1.

(4) Dynamic viscosity: For Example 1-2, the dynamic viscosity of the nourishing, moisturizing and brightening skin lotion was measured using QB/T2286-1997 "Moisturizing Lotion". The measured data are recorded in Table 1.

(5) Heat resistance: For Example 1-2, the nourishing, moisturizing and brightening lotion was placed at (40±1)°C for 24 hours. After returning to room temperature, the performance difference was compared with that before the test. The results are recorded in Table 1.

(6) Cold resistance: For Example 1-2, the nourishing, moisturizing and brightening lotion was placed at (-8±2)°C for 24 hours. After returning to room temperature, the performance difference was compared with that before the test. The results are recorded in Table 1.

(7) Centrifugal test: Inject the sample into the centrifuge tube to about two-thirds of its height and plug it with a cork. Then put it into an electric constant temperature incubator pre-adjusted to 38±1℃. After keeping warm for 1 hour, immediately move it into a centrifuge adjusted to a centrifugal speed of 2000r/min. Centrifuge for 30 minutes, take it out for observation, and record the results in Table 1.

2. Efficacy and performance

10 volunteers aged between 25 and 50 were selected to participate in the test. During the test, the subjects used the nourishing and moisturizing toner prepared in Example 1 on their entire face, twice a day, in the morning and at night, for 28 consecutive days; the test product was used twice a day on the inner forearm area of a random side for 28 consecutive days, and the inner forearm area of the other side was a blank control. Before the use of the product (0 day), 14 days and 28 days after the product was used, the skin moisture content and skin color test were performed on the cheek of a random side and the inner forearm of both sides. The skin moisture content was tested using a skin moisture tester, and the ITA° value and L ^* value of the skin were tested using a skin tester. The ITA° value is the skin color value, the higher the value, the lighter the skin color, and the L ^* value is the skin brightness, the larger the value, the more the color tends to be white. The statistical method is the Dunnett-t test for time point comparison, and the significance is: "+": significant difference (p≤0.05); "-": non-significant difference (p>0.05), and the Dunnett-t test results are recorded in Table 2 and Table 3, respectively.
