The preparation method is also the same as in example 3.

The anti-aging firming creams prepared in examples 1-13 were provided to volunteers for 4-week use. Samples 1-13 are combination 1 (example 1+ example 2), combination 2 (example 1+ example 3), combination 3 (example 2+ example 3), combination 4 (example 3+ example 4), combination 5 (example 3+ example 5), combination 6 (example 3+ example 6), combination 7 (example 3+ example 7), combination 8 (example 3+ example 8), combination 9 (example 3+ example 9), combination 10 (example 3+ example 10), combination 11 (example 3+ example 11), combination 12 (example 3+ example 12), combination 13 (example 3+ example 13), respectively; 10 volunteers, male and female, normal skin were randomly selected for each sample.

The using method comprises the following steps: the anti-aging firming face cream in the sample is used for half face after face cleaning.

After the trial, the volunteers score according to the evaluation indexes. The evaluation index is shown in the following table, and the index evaluation maximum score of 5, and the larger the numerical value, the higher the degree of the corresponding index, or the better the mildness.

After the end of the trial, the evaluation results (average values) of the volunteers on the anti-aging firming creams prepared in examples 1 to 13 are shown in the following table.

The self-evaluation effect graphs of the volunteers of the anti-aging firming cream compositions of the embodiments 1-3 are shown in fig. 1, and according to feedback of the volunteers and the test results, the cream composition disclosed by the invention is good in use experience, moist but not sticky, mild and non-irritant, has remarkable effects on fading fine wrinkles and firming skin, and enables aged skin to be improved and become firmer.

The product of the cream composition of example 3 has relatively optimal skin feel and efficacy, and is moist and non-sticky during use.

The cream composition of comparative example 1 was provided to volunteers in the same manner. Since the functional component DERMAXYL was not added to the cream composition of comparative example 1, the skin anti-aging effect was found to be less significant after a long-term use. By adding the DERMAXYL component, the main active component palmitoyl hexapeptide-12 in the DERMAXYL has similar substances capable of inhibiting nerve conduction, blocking conduction function between nerve muscles, avoiding excessive muscle contraction, relieving muscle contraction force, relaxing muscles, reducing dynamic wrinkles, eliminating fine wrinkles and preventing fine wrinkles from forming; effectively reorganizes the elasticity of collagen, can increase the activity of elastin, relaxes the lines of the face, and smoothes wrinkles and improves laxity.

The cream composition of comparative example 2 did not have the glyceryl stearate/PEG-100 stearate emulsifier added, resulting in insufficient emulsifier in the formulation to emulsify the entire oil and eventually oil-water separation, failing the stability test. A good product must be subjected to stringent stability tests before it can be marketed. The material stability test generally comprises high temperature (40-50 ℃), low temperature (minus 10-minus 18 ℃), light stability test and high and low temperature alternating and cold cycle test, and the stability of the material is qualified when the material is not discolored, not layered or thickened for 3-6 months. While it may be possible to make a stable product using other emulsifiers, the skin feel of the product may be affected, as in comparative example 7, when polysorbate 81 is substituted for the glyceryl stearate/PEG-100 stearate in phase B of example 3, the stability of the cream composition of comparative example 7 is acceptable, but the slimy feel is evident and the skin feel is poor compared to the cream composition of example 3.

The cream composition of comparative example 3 had no added ammonium acryloyldimethyltaurate/VP copolymer and the consistency of the product was not sufficient to achieve the cream texture. If the ammonium acryloyldimethyltaurate/VP copolymer is replaced by other thickening agents, such as the comparative example 8, and carbomer is used for replacing the ammonium acryloyldimethyltaurate/VP copolymer, not only the skin feel is affected and the slimy feel is obviously increased (the slimy feel is evaluated by the evaluation method, and the slimy feel is 3.1), but also the addition of raw materials with ionic properties (such as general extract functional ingredients) is limited due to the stability problem. As in comparative example 9, no acrylamide/VP copolymer was added, and the amount of xanthan gum used in the cream composition was increased to 0.5 parts, and although the product of comparative example 9 produced a cream texture, the skin feel was poor, and the product felt sticky during use (evaluated by the above evaluation method, and a sticky feel score of 2.9), whereas the good cream product was very contraindicated for sticky feel. However, when the composition uses the ammonium acryloyldimethyl taurate/VP copolymer as the thickener, a small amount of xanthan gum is added, so that the thickening is assisted, the stability of the product can be improved, the skin feel of the product can be improved, and the sticky feel can be reduced, for example, in the cream compositions of examples 3 and 8-10, the cream composition of example 3 is moist and not sticky in the using process, and the skin feel is better than that of examples 8-10.

Compared with the cream composition in the embodiment 3, the cream composition in the embodiment 4 has poor skin feeling (evaluated by the evaluation method, the ductility score is 3.9, the greasy feeling score is 2.7, the absorption speed is 4.3, the moisture retention is 4.1 min, the moisture is 3.8, the tightening effect is 4, the fine line fading effect is 4.1 min, and the mildness is 4.3 min) compared with the cream composition in the embodiment 3 in which sodium stearyl glutamate is not added, namely, the skin feeling can be effectively improved by adding a small amount of sodium stearyl glutamate, the system is helped to form a liquid crystal structure, the slow release effect on the functional components in the formula is achieved to a certain extent, and the bioavailability of the functional components is improved. Meanwhile, the addition of a small amount of sodium stearyl glutamate is helpful to make the emulsified particle size of the system smaller and the stability of the system better, as shown in fig. 2, the left a is a control group (comparative example 4), the right b is a group added with 0.2 wt% of sodium stearyl glutamate (example 3), and the emulsified particle size of b is smaller and more dispersed.

Comparative example 5 no methylparaben was added and the cream composition of comparative example 5 failed the fungal test as detected by the preservative challenge microorganisms. The methyl hydroxybenzoate in the formula can pass a corrosion prevention challenge test when the addition amount exceeds 0.12%, but long-term experimental tests show that the addition amount is preferably not more than 0.2 wt% in the product, otherwise potential risks such as irritation are brought, and the addition amount is reduced as far as possible under the condition of preventing the product from rotting and deteriorating. Some of the traditional preservatives in the preservative list may have better and cheaper preservative effect, but the traditional preservatives are not high in mildness or have potential carcinogenic risks, and the like, if the traditional preservatives in the non-preservative list can have preservative effect, the cost is greatly increased, for example, 1, 2-hexanediol has preservative effect, but is not suitable for being used alone, the cost is too high, the irritation of the product is greatly increased if the dosage exceeds 0.5 wt%, and in addition, the product independently uses 1, 2-hexanediol as the preservative, and even if the dosage is 0.5 wt%, the product cannot pass the preservative challenge microorganism test. Therefore, the anticorrosion system of the formula of the cosmetic generally needs reasonable compounding of a plurality of components, and meets the declared requirements of products or cost limiting conditions and the like.

Comparative example 6 pentaerythritol tetrakis (bis-tert-butylhydroxyhydrocinnamate) was not added, the oxidative deterioration of oil in the product was retarded to some extent, vegetable oil in the formula was generally very easy to be oxidized, rancid and the like, for example, the fruit fat of Butyrospermum PARKII (Butyrospermum PARKII) in the formula is a component which is relatively easy to be oxidized, and if pentaerythritol tetrakis (bis-tert-butylhydroxyhydrocinnamate) was not added in the formula, the product was found to be more discolored than the product with pentaerythritol tetrakis (bis-tert-butylhydroxyhydrocinnamate) in the stability test, and the comparison was obvious around 2-3 months. In addition, 2, 6-di-tert-butyl-4-methylphenol can also delay the oxidative deterioration of oil in the product, but the effect of pentaerythritol tetra (bis-tert-butyl hydroxy hydrocinnamic acid) ester is relatively better through comparison tests, and the color of the product changes within 3 months in a high temperature (40-50 ℃) stability test like the cream composition of comparative example 10.

The technical contents of the present invention are further illustrated by the examples, so as to facilitate the understanding of the reader, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation based on the present invention is protected by the present invention.
