Technical Field

The application relates to the technical field of washing and caring product components, in particular to a compound grease composition, a preparation method and application thereof.

Background

Cleaning products are a type of cleaning product that consumers are exposed to at high frequencies, and the safety of cleaning products is becoming increasingly interesting. The existing skin cleaning products can remove grease, cuticle fragments or residues of beauty cosmetics on the skin, and the like, and can cause excessive cleaning, thus having adverse effects on skin barriers, such as damage to sebum membranes, keratin denaturation, skin irritation and the like, so that the skin is exposed and damaged by air and sunlight in external conditions, particularly by the influence of environmental polluted air, and skin damage caused by long-time use is artificial damage to the skin, and the skin needs to be repaired by subsequent repair products, particularly sensitive skin and dry skin, and the sensitivity of the skin can be enhanced by adopting common washing and caring products.

In recent years, the concept of "skin care with oil" has been popular, and the selection of oils and fats or essential oils applied to the skin is equivalent to the application of a layer of sebum film on the skin surface, thereby improving a series of problems caused by skin dryness. However, at present, products with oil nourishing and skin at full oil or partial oil are generally more mentioned, such as essential oil, cleansing oil, face cream and bath oil, and the oil ratio is relatively large. However, it is difficult to add a large amount of grease to a general rinse-off product (shampoo, body wash, etc.), so that it is not expected to be effective because it is rarely mentioned or only symbolically added in the rinse-off product.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below. The specific conditions are not noted in the examples and are carried out according to conventional conditions or conditions recommended by the manufacturer. The reagents or apparatus used were conventional products commercially available without the manufacturer's attention.

It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The present application will be described in detail with reference to specific examples.

The compound grease composition is prepared by compounding the following raw materials: ethylhexyl hydrogenated olive oleate, hydrogenated olive oil non-soap compounds, glycerol oleate, glycerol caprylate/caprate, sorbitan caprylate, olive oil PEG-7 esters, tocopheryl acetate and diethoxyethyl succinate.

Ethyl hexyl hydrogenated olive oleate, hydrogenated olive oil non-soap compounds: the natural source emollient can provide soft, dry, silky and smooth skin feel to the skin, and can also provide moisture to the skin. Meanwhile, the grease has higher stability and stronger compatibility with common synthetic and natural grease. The cream can improve the extensibility of skin feel and reduce the phenomena of whitening and white streaks when being smeared when being added into a formula. And has high refractive index and silicone property, and can replace traditional silicone oil. The hair conditioner can be applied to washing and caring products, can increase the conditioning property, reduce the friction of hair and increase the glossiness of hair.

Glycerol oleate: the lipid layer on the skin contains a large amount of oleic acid monoglyceride. With age, oleic acid monoglyceride in the skin gradually decreases, moisturizing ability gradually decreases, and the skin becomes rough and shiny. The glycerol oleate can strengthen the skin lipid layer barrier, reduce the percutaneous water loss and achieve the moisturizing effect.

Glycerol caprylate/caprate: the liquid crystal structure has a promoting effect on traditional cations and synergistic conditioning performance. The foaming agent can be applied to washing and caring products to assist foaming, fine and stable. Meanwhile, the preservative is antiseptic and synergistic, the addition amount of the preservative is reduced, and the surfactant is easier to thicken.

Sorbitan octanoate: the plant source emollient can be used in resident products and rinse-off products to provide a fat-imparting effect, has little influence on foam, can be applied in a transparent system, and does not need to additionally add a solubilizer. Can be used by being compounded with the traditional preservative, and can synergistically improve the preservative effect.

Olive oil PEG-7 esters: the olive oil source can be water soluble or oil soluble. The fatting effectively improves the tight and dry feel of the washed product after washing, and does not influence the foam performance of the product. The compound of the surfactant and the glycerol can synergistically reduce the irritation of the surfactant.

Tocopheryl acetate: is a vitamin E derivative with better heat-resistant stability than tocopherol. The lipophilic hydrophobic group can enter into the biomembrane containing unsaturated fatty acid, remove free radical, maintain the stability of unsaturated fatty acid composition, achieve antioxidant effect, and assist system stability.

Diethoxyethyl succinate: can be dissolved in water or oil, has higher refractive index and smaller molecular weight, can penetrate into hair, smooth hair scales, and can be used as a silicone oil substitute. It is used as emollient, and has refreshing and greasy feeling improving effects.

The hydrogenated olive acid ethylhexyl ester, hydrogenated olive oil non-soap compound and diethoxyethyl succinate are used as silicone oil alternative grease, have silicone characteristics, and can be added into shampoo to increase the wet comb and dry comb performance of hair, but if the addition amount is large, the stability of the shampoo and the shower gel system can be affected. The application uses olive oil PEG-7 esters as the main body of the grease composition. The olive oil PEG-7 esters not only contain lipophilic groups, but also have hydrophilic groups, so that the olive oil PEG-7 esters can be used for increasing the capacity of grease in shampoo and bath lotion systems, and simultaneously can be used for providing grease, and the irritation caused by the surfactant is reduced. Therefore, on the basis of olive oil PEG-7 esters, hydrogenated olive oil ethylhexyl oleate, hydrogenated olive oil non-soap compounds and diethoxyethyl succinate are matched in the skin-moistening emulsion product, so that the phenomenon of white streaks can be reduced, and the moisture retention is increased.

The compound use of the glyceryl caprylate/caprate and the sorbitan caprylate can increase the efficacy of the antiseptic grease, reduce the use of the traditional antiseptic, and can thicken and stabilize bubbles in the washing and caring products.

The glycerol oleate is a skin-like lipid layer component grease, can strengthen skin barrier, and can synergistically strengthen moisturizing performance with other grease.

The oil and fat composition contains unsaturated bonds and is easily oxidized. On the basis of the application, tocopheryl acetate is added as an antioxidant to prevent the whole grease composition from oxidation. Can also be added into specific product formulation to prevent oxidation of skin belt and reduce free radical damage.

In summary, the various oils and fats of the application are matched and coordinated with each other to form the comprehensive oil and fat composition, which can be applied in various directions.

In some embodiments of the present application, the above composition is formulated by the following raw materials in weight percent: 11.7 to 36.5625 percent of hydrogenated olive oil ethylhexyl oleate, 0.3 to 0.9375 percent of hydrogenated olive oil nonsoap compound, 1 to 5 percent of glycerol oleate, 5 to 10 percent of glycerol caprylate/caprate, 5 to 10 percent of sorbitan caprylate, 12.5 to 74 percent of olive oil PEG-7 ester, 2 to 10 percent of tocopheryl acetate and 1 to 15 percent of diethoxyethyl succinate.

In the application, the compound grease composition is applied to specific washing and caring products according to the proportion of 0.2-16%, and obvious effects can be achieved by adding 5% of hydrogenated olive oil ethylhexyl oleate and hydrogenated olive oil non-soap compounds; the glycerol oleate has obvious fat-forming effect of 0.2 to 1 percent; the glycerol caprylate/caprate and sorbitan caprylate are added with 0.5-2% of the components, so that the effects of synergism and corrosion prevention can be achieved; the diethoxyethyl succinate can help to enhance the effect of hydrogenated ethylhexyl oleate and hydrogenated olive oil non-soap compounds; the tocopheryl acetate starts to play an oxidation resistance at above 0.5%. Therefore, the raw material proportion of the proportion can achieve the best comprehensive effect after experiments.

The preparation process of the compound grease composition includes the steps of mixing the materials at 50-60 deg.c.

An application of a compound grease composition in preparing washing and caring products.

In some embodiments of the present application, the above-described cleansing products include body washes, hair creams, and lotions.

In some embodiments of the present application, the above-described compounded oil composition is added to the cleaning product in a proportion of 0.2 to 16%.

The features and capabilities of the present application are described in further detail below in connection with the examples.

Example 1

In this embodiment, the compound grease composition is applied to a sulfate surfactant system body wash, and the body wash not only contains the compound grease composition, but also may include a surfactant, a pH regulator, a chelating agent, a thickener, a humectant and water.

In this example, 5 application examples (application examples 1 to 5) and 1 blank control example were set, and the component ratios (mass percentages) of the respective groups of products are shown in table 1.

TABLE 1

The preparation process comprises the following steps:

S1, uniformly stirring, dissolving and dispersing surfactant components (sodium laureth sulfate, cocoamide MEA and decyl glucoside), citric acid, EDTA2Na, glycerol and water, and gradually heating to 80 ℃ for later use;

S2, heating, mixing and dispersing the grease combined raw materials at 50-60 ℃ in advance, and adding the grease combined raw materials into an S1 system after the temperature is reduced to 50 ℃;

s3, naturally cooling the S2 system to 45 ℃, adding phenoxyethanol, and stirring and dispersing uniformly to obtain the sulfate surfactant system shower gel.

The body wash products of each application example and blank 1 were subjected to a percutaneous moisture loss test. The vapoMeter uses the closed cavity measurement principle, so that the measurement is not influenced by indoor air flow, the relative humidity and the temperature sensor are used for measuring the linear increase of the relative humidity in the closed cavity, and the TEWL value of the percutaneous moisture loss is calculated according to the increase of the relative humidity. The greater the TEWL value, the higher the skin moisture loss. The test sets 3 time measurement points, initial TEWL values for skin unused product. The test area was rubbed with a blank and application group 1-5 products for 2min, rinsed with 37℃ water, blotted to dry skin surface moisture, and measured for 1min for TEWL value. TEWL values were measured after 10min of rest.

Test time: for 10min; number of test persons: 12 persons; test environment: 25 ℃ +/-0.5 ℃ and 55% +/-5% of humidity; test instrument: a vapoMeter; test part: the amount of the medicine to be used is 18mg, 3cm×3cm on the inner side of the forearm of both hands. The skin TEWL values of the test areas of this example are shown in table 2, and the curves of the changes are shown in fig. 1.

TABLE 2

As can be seen from Table 2 and FIG. 1, the TEWL values of both blank 1 and application examples 1 to 5 were reduced 1min after washing with the body wash, because the moisture had not evaporated to dryness at the time of skin washing. The TEWL values of the application groups are lower than those of the blank control groups, so that the grease combination has a grease-forming effect, and the grease stays on the skin to a certain extent after flushing, so that the evaporation of the skin moisture is slowed down. The increase in oil composition reduced transdermal water loss 10min after washing with body wash, compared to the placebo group, or was comparable to the skin TEWL value before body wash.

Example 2

The present example applies the formulated oil composition to hair care cream. In this example, 10 experimental groups were set for comparison (application examples 6 to 15), and the formulation ratios (mass percentages) thereof are shown in Table 3.

TABLE 3 Table 3

The preparation process comprises the following steps:

S1, mixing oil phase raw materials MONTANOV, behenyl trimethyl ammonium chloride, cetostearyl alcohol and grease, stirring, dissolving and heating to 85 ℃ to obtain an oil phase mixture;

S2, stirring, dispersing and dissolving water phase raw materials of EDTA2Na, polyquaternium-10, hydroxyethyl cellulose, glycerol and water, and gradually heating to a water phase mixture of 85 ℃;

s3, adding the oil phase mixture into the water phase mixture, homogenizing for 5-8min at 25-30Hz, continuously stirring and cooling to 45 ℃, and adding phenoxyethanol to obtain the hair care emulsion product.

The hair care cream products of application examples 6 to 15 were subjected to a coefficient of friction test: using 2g of hair cream of application examples 6 to 15, the wet friction coefficient of the hair tress was measured by a friction coefficient meter by sucking water to dry the hair tress of 25g in length of 50cm with a clean water. The hair tresses were then dried and tested for dry friction coefficient. The dry and wet coefficient of friction data after treatment of the hair beam for each application example 6-15 samples were averaged over 3 valid replicates. A blank comparison was established in which hair bundles 50cm long and 25g weight were directly rinsed with clear water, after which treatment and testing were carried out in the same manner. The test results of each experimental group are shown in table 4.

TABLE 4 Table 4

As can be seen from Table 4, application example 7 compared with application example 8, the wet comb properties of diethoxyethyl succinate are better than the combination of hydrogenated ethylhexyl oleate and hydrogenated olive oil non-soap compounds, and the dry comb properties are the opposite; compared with application examples 9 and 10, application examples 7 and 8 are added with glycerol oleate, so that the dry comb property can be improved, and the wet comb property can be improved; application examples 9, 10 showed improved wet comb performance but no improvement in dry comb performance compared to application examples 11, 12 with olive oil PEG-7 esters; compared with application example 13, application example 10 has obviously improved wet comb property and can maintain certain dry comb property; application example 15 significantly improved wet and dry combing performance. In conclusion, the components in the compound grease composition are matched with each other to finally realize good wet comb property and dry comb property.

Example 3

The present example applies a formulated oil composition to a emollient cream. In this example, 8 experimental groups were set for comparison (application examples 16 to 23), and a blank control group 2 and a silicone oil control group were set for comparison; the formulation proportions (mass percent) are shown in Table 5.

TABLE 5

The preparation process comprises the following steps:

s1, stirring, dissolving and heating oil phase raw materials MONTANOV and MONTANOV, TEGO CARE 165, cetostearyl alcohol, ethylhexyl palmitate, polydimethylsiloxane and/or a compound oil fat to 85 ℃ to obtain an oil phase mixture;

S2, stirring, dispersing and dissolving water phase raw materials of EDTA2Na, carbomer, glycerol and water, and gradually heating to 85 ℃ to obtain a water phase mixture;

S3, adding the oil phase mixture into the water phase mixture, homogenizing for 5-8min at 25-30Hz, continuously stirring and cooling to 45 ℃, and adding phenoxyethanol to obtain the skin cream product.

1) And (3) coating contrast test:

The skin cream of the blank 2, silicone oil control, application example 16, application example 17 was sampled 0.1g and spread back and forth 15 times in the area at 3cm×5cm inside the right-hand forearm. The results of the comparison between the blank 2 and each of the grease-added compositions are shown in fig. 2 to 4.

As can be seen from FIGS. 2 to 4, application examples 16 and 17 are capable of significantly improving the "white streak" phenomenon during application, increasing the ductility thereof, and being added as a silicone oil component instead.

2) And (3) moisture preservation effect comparison test:

the method refers to QB/T4256-2011 cosmetic moisturizing efficacy evaluation guidelines, and adopts a capacitance method to measure the moisture content of the skin horny layer of a human body. The capacitance measured is proportional to the water content of the surface layer of the skin, a parameter which may be representative of the moisture content of the stratum corneum of the skin. Higher measurements indicate higher moisture content of the stratum corneum.

Setting 4 time measuring points, and measuring the initial hydration value before the skin is not coated with the product, and measuring the skin hydration value after 60min, 90min and 120min after the product is coated. Test time: 2h; number of test persons: 12 persons; test environment: 25 ℃ +/-0.5 ℃ and 55% +/-5% of humidity; test instrument: moistureMeter SC; test part: the dosage of the inner sides of the forearms of the two hands is 3cm multiplied by 3cm, and 18mg is used; the results are shown in Table 6 and FIG. 5.

TABLE 6

As can be seen from Table 6 and FIG. 5, adjusting the content of the species in the fat and oil composition, the hydrogenated olive oil ethylhexyl ester and the hydrogenated olive oil non-soap compound, glycerol oleate, can increase skin hydration and slow down the loss of moisture. The skin hydration rate is obviously improved within 60 minutes after the sorbitan octoate is added, but the maintenance degree is lower. The addition of diethoxyethyl succinate reduces the "white streak" production, but does not improve the skin moisture content, the application adopts the mode of compounding and adjusting the proportion, thereby not only improving the moisture content of the skin, but also reducing the generation of 'white strips'.
