Description

Technical Field

[0001] The invention relates to the technical field of skin care products, and in particular to a multi-effect skin care mask containing a papaya extract and a preparation method thereof. Background Art

[0002] In today's beauty and skin care market, facial masks are a convenient and efficient skin care product that is favored by consumers. Consumers' demand for facial masks is no longer limited to basic moisturizing functions, but they expect them to have multiple functions to deal with different skin problems.

[0003] As a natural plant resource rich in a variety of bioactive ingredients, papaya has great potential value in the field of skin care. The peel of papaya is rich in flavonoids, organic acids, and various vitamins. Flavonoids are a class of natural antioxidants that can effectively remove free radicals in the body. Free radicals are one of the important factors leading to skin aging. They can destroy structural components such as collagen and elastic fibers in skin cells, causing the skin to lose elasticity and wrinkles. They can also cause skin pigmentation, dullness, spots and other problems. Organic acids help regulate the pH value of the skin, maintain the balance of the microecology on the surface of the skin, promote the normal metabolism of skin cells, and keep the skin in a healthy physiological state.

[0004] Papaya seed gum extract is rich in polysaccharides. These polysaccharides have excellent moisturizing properties in skin care. They can form a moisturizing film on the skin surface, tightly lock the moisture in the skin, prevent excessive water loss, and thus maintain the moisture and elasticity of the skin. The skin's moisturizing ability will gradually decrease when it is in a dry environment for a long time or with age, and it is prone to dryness, roughness and other problems. The moisturizing effect of Papaya seed gum extract can effectively alleviate these skin problems.

[0005] Papaya seed oil is rich in unsaturated fatty acids, such as oleic acid and linoleic acid. These unsaturated fatty acids are essential for maintaining the barrier function of the skin. They can replenish the lipids between skin cells, enhance the skin's ability to moisturize and resist external stimuli. Damage to the skin's barrier function can make the skin sensitive and fragile, and easily attacked by external environmental factors such as ultraviolet rays and pollutants, causing skin inflammation, allergies and other problems. The nourishing effect of papaya seed oil can repair and strengthen the skin barrier and protect the skin from damage.

[0006] However, although some facial mask products on the market contain Papaya extract, most of them only use a part of its ingredients, and fail to fully tap the skin care potential of the whole fruit of Papaya. In addition, in the extraction process, there may be problems such as low extraction efficiency and large loss of effective ingredients. In terms of formula design, the extracts from different parts of Papaya are not scientifically and reasonably matched with other skin care ingredients to achieve synergistic multi-effect skin care functions. Therefore, the development of a multi-effect skin care mask that can comprehensively utilize extracts from different parts of Papaya peel, seed gum, seed oil, etc., and combine a variety of other effective skin care ingredients, has a very broad market prospect and important practical significance, can meet consumers' urgent needs for high-quality, multi-functional mask products, and provide all-round care and care for the skin.

[0162] Beneficial effects of the present invention:

[0163] 1. The facial mask of the present invention achieves all-round moisturizing effect with the help of multiple ingredients. The rich polysaccharides in the light papaya seed gum extract can build a dense moisturizing network on the surface of the skin, strongly lock the moisture in the skin and prevent it from being lost. Sodium hyaluronate, with its excellent moisture absorption and water retention properties, can absorb a large amount of water and retain it on the skin surface for a long time, and cooperate with ingredients such as glycerin, trehalose and sorbitol to further enhance the moisturizing effect of the skin. These ingredients work together to effectively increase the water content of the skin, keep the skin soft, smooth and elastic at all times, fundamentally improve the problems of roughness and desquamation caused by lack of water, and reshape the skin's moisture barrier.

[0164] 2. The mask of the present invention has strong antioxidant effect and resists the aging process of the skin. The extract of papaya peel is rich in antioxidant ingredients such as flavonoids, and is combined with vitamin C and vitamin E to build a powerful antioxidant defense line. Flavonoids can efficiently scavenge free radicals, block the chain reaction caused by free radicals, and protect key structures such as lipids, proteins and DNA of skin cells from oxidative damage. Vitamin C not only inhibits the production of melanin, but also plays an important role in the anti-oxidation process, synergizing with vitamin E to enhance the overall antioxidant capacity. Long-term use can significantly delay skin aging, reduce signs of aging such as wrinkles, sagging and dullness, keep the skin firm, shiny and elastic, and rejuvenate.

[0165] 3. The mask of the present invention has the functions of precise whitening and freckle removal, brightening the skin color. Vitamin C, as a classic whitening ingredient, plays a key role in this mask. It reduces the synthesis of melanin from the source by effectively inhibiting the activity of tyrosinase, and at the same time has the ability to restore the formed melanin, which promotes the fading of spots and even white skin color. The organic acids and other ingredients in the extract of papaya peel can also help regulate skin metabolism, promote the decomposition and excretion of melanin, and work with vitamin C to precisely act on whitening and freckle removal, significantly improve skin pigmentation problems, restore the skin to a white and translucent state, and improve the overall uniformity and brightness of the skin color.

[0166] 4. The facial mask of the present invention has the functions of soothing and repairing damaged skin and enhancing skin tolerance. Allantoin plays an important role in soothing and repairing in the facial mask. When the skin is attacked by adverse external factors such as ultraviolet rays and chemicals and suffers from discomforts such as redness, swelling, itching, and inflammation, allantoin can promote hydration of the stratum corneum, increase the water content of the skin, relieve dryness and tightness, and reduce discomfort. At the same time, it can accelerate the regeneration and repair process of skin cells, help the healing of damaged tissues, strengthen the skin barrier function, improve the skin's tolerance to various stimuli, and quickly restore the skin to a healthy and stable state, effectively prevent skin problems caused by external factors, and protect skin health.

[0167] 5. The facial mask of the present invention has the function of deeply nourishing the skin and strengthening the skin barrier function. The unsaturated fatty acids in the light papaya seed oil, such as oleic acid and linoleic acid, provide deep nourishment for the skin. These unsaturated fatty acids can penetrate into the skin cells, replenish intercellular lipids, enhance the skin barrier function, and effectively resist the invasion of harmful factors such as ultraviolet rays, pollutants, and microorganisms in the external environment. At the same time, they promote the regeneration and repair of skin cells, improve skin texture, make the skin more delicate, firm, and elastic, and long-term use can maintain the skin healthy and tough, and enhance the skin's ability to resist external aggression.

[0168] 6. The present invention uses the peel and seeds, which are by-products of papaya processing, as cosmetic raw materials, which can effectively increase its added value, promote the utilization of all components of papaya resources, maximize its value, form a circulation model of "resources-products-waste-renewable resources", and promote the healthy development of the papaya industry.

[0187] A certain amount of triethanolamine, papaya peel extract, panthenol, propylene glycol, hexylene glycol, squalane, papaya seed gum extract, phenoxyethanol, glycerin, papaya seed oil and cyclopentasiloxane are mixed according to mass percentage, and stirred at 45° C.-55° C. to obtain a mixed solution B, referred to as phase B;

[0188] Step 6: Prepare mixed solution C:

[0189] Add phase B to phase A, add a certain amount of p-hydroxyacetophenone, vitamin C and vitamin E to phase A mixed with phase B according to mass percentage, stir evenly at 20°C-35°C to obtain a mixed solution C, referred to as phase C;

[0190] Step 7: Prepare the mask:

[0191] The pH of phase C is adjusted to between 4.0 and 8.5 with a phosphate buffer solution, and then homogenized in a homogenizer to obtain a facial mask liquid. The facial mask cloth is placed in an aluminum foil bag, and an appropriate amount of the facial mask liquid is added, and finally vacuum-sealed to obtain a facial mask.

[0192] Embodiments 2 to 6

[0193] The raw materials and preparation steps used in the multi-effect skin care masks containing papaya extract in Examples 2 to 6 are the same as those in Example 1, with the only difference being the different mass percentages of papaya peel extract. The added amount of papaya peel extract is changed (1%, 2%, 3%, 4%, 5%), and the optimal added amount is determined by sensory scoring.

[0194] Comparative Example 1

[0195] The raw materials and preparation steps of the multi-effect skin care mask containing papaya extract in comparative example 1 are the same as those of the multi-effect skin care mask containing papaya extract in embodiment 1, the only difference is that papaya peel extract is not added to the mask liquid in comparative example 1.

[0196] Comparative Example 2

[0197] The raw materials and preparation steps of the multi-effect skin care mask containing papaya extract in comparative example 2 are the same as those of the multi-effect skin care mask containing papaya extract in example 1, the only difference is that papaya seed gum extract is not added to the mask liquid in comparative example 2.

[0198] Comparative Example 3

[0199] The raw materials and preparation steps of the multi-effect skin care mask containing papaya extract in comparative example 3 are the same as those of the multi-effect skin care mask containing papaya extract in example 1, the only difference is that papaya peel extract and papaya seed gum extract are not added to the mask liquid of comparative example 3.

[0200] The efficacy of the mask is evaluated as follows:

[0201] 1. Whitening efficacy study - tyrosinase activity inhibition test

[0202] Depend on Figure 1 It can be seen that the mask liquids of different concentrations have a good inhibitory effect on tyrosinase activity, and the tyrosinase activity inhibition rate increases accordingly with the increase of concentration. The relative inhibition rate of the mask liquid in Example 1 on tyrosinase is higher than that in Comparative Examples 1-3, indicating that the multi-effect skin care mask containing the extract of Papaya quince has better whitening effect than the mask liquid containing only a single extract, and also indicating that the components of the multi-effect skin care mask containing the extract of Papaya quince can play a synergistic role. Therefore, the mask liquid prepared by the technical solution of the present invention has a good whitening effect.

[0203] 2. Antioxidant efficacy study - DPPH free radical scavenging test

[0204] Depend on Figure 2 It can be seen that the mask liquids of different concentrations have the effect of scavenging free radicals. As the concentration of the mask liquid increases, the scavenging effect of free radicals also increases. The scavenging rate of the mask liquid in Example 1 on DPPH free radicals is higher than that in Comparative Examples 1-3, indicating that the multi-effect skin care mask containing the light-skinned papaya extract of the present invention has better antioxidant effect than other mask liquids containing only a single extract. By scavenging free radicals, the formation of melanin can be effectively reduced and the anti-aging ability of human skin can be improved. The test results are consistent with the test results of tyrosinase inhibition rate.

[0205] Depend on Figure 3It can be seen that when other conditions remain unchanged, the sensory score increases first and then decreases when the amount of papaya peel extract added (1%, 2%, 3%, 4%, 5%) is changed. Papaya peel extract is the main active ingredient in the mask. If the amount added is too little, the active ingredient content is low, the skin care effect is poor, and the color is lighter. If the amount added is too much, the color is darker, which affects the appearance of the product. Figure 4 The results showed that the optimal addition amount of papaya peel extract was 3%.

[0206] 3. Moisturizing effect research

[0207] Depend on Figure 4 It can be seen that the moisturizing rate of the mask liquid decreases with the increase of time, and the moisturizing rate can still reach more than 85% after 40 minutes, indicating that the mask liquid has a good moisturizing effect and can play a long-term moisturizing and water-locking performance.

[0208] 4. Sensory evaluation of facial masks

[0209] The mask liquid was given a comprehensive sensory evaluation using the indicators and evaluation methods described in Table 1.

[0210] Table 1 Comprehensive sensory evaluation table of facial mask liquid

[0211]

[0212]

[0213] 50 people of different ages were selected to conduct sensory evaluation on the mask. The evaluation criteria were as follows: the same batch of masks prepared by the technical solution of the present invention were distributed to 50 appraisal members, and other conditions were guaranteed to be the same. The appraisal members were asked to try the masks and evaluate and score according to their subjective feelings. A score sheet was issued, and the scoring criteria and scoring method were explained to the appraisal members. The total score of the sensory evaluation of the mask was 100 points, which was divided into 4 levels, namely very good (≧90 points), relatively good (<90 points, ≧70 points), acceptable (<70 points, ≧50 points), and unacceptable (<50 points). There were 5 evaluation indicators, namely fineness, uniformity, viscosity, color, and smell. The scores were 20 points respectively. After the appraisal personnel finished the evaluation, the scoring sheet was collected and statistics were performed. The scores of the 5 evaluation indicators were averaged, and the scores obtained were the sensory scores.

[0214] Depend on Figure 5 It can be seen that almost everyone can accept the light papaya mask liquid. Among the five indicators of the mask liquid, fineness, uniformity, viscosity, color, and smell, the fineness, uniformity, color, and smell are rated very good. The viscosity experience score is second, and most people are very satisfied. The total score of the test group for the light papaya mask is 94 points, which corresponds to a very good level.

[0215] The examples given in the present invention are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
