Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a composition containing fruit acid and hydrolyzed collagen zinc and a preparation method thereof. Background Art

[0002] Malic acid, also known as 2-hydroxysuccinic acid, has two stereoisomers due to an asymmetric carbon atom in the molecule. In nature, it exists in three forms, namely D-malic acid, L-malic acid and its mixture DL-malic acid. It is a white crystal or crystalline powder, has strong hygroscopicity, is easily soluble in water and ethanol, and has a special pleasant sour taste. Malic acid is mainly used in the food and pharmaceutical industries. Mandelic acid is a natural organic acid that is commonly found in almonds. It has many functions such as moisturizing, anti-oxidation, whitening, and exfoliation, and is widely used in cosmetics. Lactobionic acid is called the third generation of fruit acid. It is an acid that exists naturally in the human body. Lactobionic acid is an advanced fruit acid that combines multiple functions such as repair, anti-aging, moisturizing, anti-oxidation, and promoting body renewal. Its structure and physical properties give lactobionic acid many application values. At present, lactobionic acid has been widely used in the food industry, pharmaceutical industry, fine chemical industry, cosmetics industry, etc.

[0003] Malic acid, mandelic acid, and lactobionic acid are widely used as cosmetic ingredients in oil control, freckle removal, and acne removal products. However, most existing products add only one acid, and no research has been conducted on the simultaneous addition of the three ingredients. The present invention is based on the above considerations, and thus proposes to study the effects of the simultaneous addition of the three fruit acids on cosmetic oil control, dullness relief, and other aspects. Summary of the invention

[0004] The purpose of the present invention is to provide a composition containing fruit acid and hydrolyzed collagen zinc and a preparation method thereof. The prepared composition has good oil control effect, moisturizing and repairing effects, and the storage stability of the composition is good.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A composition containing fruit acid and hydrolyzed collagen zinc, comprising the following raw materials in mass fractions, the total mass fraction of the raw materials being 100%:

[0007] Phase A: Malic acid 0.3-2%, mandelic acid 0.1-2%, lactobionic acid 0.3-2%, hydrolyzed collagen zinc 0.05-1%, polyol 7-9%, tocopherol 0.2-0.7%, panthenol 0.2-0.5%, raspberry ketone 0.3-0.7%, allantoin 0.3-0.8%, niacinamide 1-5%, α-arbutin 0.5-1%, sodium hyaluronate 3-7%, water to make up the rest;

[0008] Phase B: Centella asiatica extract 0.1-0.3%, Chondrus crispus extract 0.2-0.5%, Paeonia lactiflora root extract 0.3-0.6%, Panax ginseng root extract 0.1-0.3%, Glycyrrhiza glabra root extract 0.2-0.8%, Black tea extract 1-1.5%, Grape fruit cell extract 0.1-0.5% and Kava Piper melongena leaf rhizome extract 2-5%;

[0009] Phase C: 1-2% diisostearyl malate, 2-4% ethylhexyl palmitate and 6-8% emulsifier;

[0010] Phase D: thickener 0.05-0.1%, chelating agent 0.1-0.3% and maltodextrin 0.1-0.2%.

[0011] Furthermore, the mass ratio of the polyol to the Kava Piper methysticum leaf rhizome extract is 2-3:1.

[0012] Furthermore, the polyol is a compound of polyethylene glycol, glycerol and sorbitol in a mass ratio of 2-3:1:0.5-0.8.

[0013] Furthermore, the weight average molecular weight of the polyethylene glycol is 1000-1300.

[0014] The present invention compounds malic acid, mandelic acid, and lactobionic acid with a variety of raw materials to synergize and enhance the effect. The obtained composition has excellent oil control effect, helps to alleviate the problem of enlarged pores, and is significantly better than the effect of adding a single fruit acid. However, it was found during the experiment that when the total amount of the three fruit acids added exceeded 6%, the oil control and whitening effects were better, but it may cause irritation to the skin. Kava pepper root extract has the effect of inhibiting excessive sebum secretion. The inventor unexpectedly found that adding a specific proportion of polyols and kava pepper leaf rhizome extract to the system of the present invention can show a synergistic effect of reducing the irritation of the three fruit acids. It is speculated that after the polyols and kava pepper leaf rhizome extract are compounded, the permeability of the three fruit acids on the skin can be synergistically increased, and the irritation of the three fruit acids to the local skin can be reduced. The inventor found that the weight average molecular weight of polyethylene glycol is 1000-1300, which is more obvious in reducing the irritation of fruit acids.

[0015] Furthermore, the emulsifier is selected from one or more of fatty alcohol polyoxyethylene ether AEO-15, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane, and cetyl PEG / PPG-10 / 1 polydimethylsiloxane.

[0016] Furthermore, the emulsifier is a compound of fatty alcohol polyoxyethylene ether AEO-15, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane in a mass ratio of 0.3-0.7:1:1.5-2.0.

[0017] The present invention can synergistically have the effects of oil control and dullness relief by adding three kinds of fruit acids, hydrolyzed collagen zinc and a variety of plant extracts to the composition. However, due to the complexity of the active ingredients in the system, the stability of the system is poor, especially when stored for a certain period of time under low or high temperature conditions, unstable phenomena such as precipitation and stratification are prone to occur. The present invention adds an emulsifier compounded with fatty alcohol polyoxyethylene ether AEO-15, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane to the system to improve the stability of the composition. When fatty alcohol polyoxyethylene ether AEO-15, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane are compounded in a specific ratio, the storage stability under variable temperature conditions is also improved.

[0018] Furthermore, the chelating agent is selected from one or more of EDTA-2Na, EDTA-3Na, and caprylhydroxamic acid.

[0019] Further,.

[0020] Furthermore, the thickener is selected from one or more of xanthan gum, carrageenan, carbomer, high molecular weight cellulose, and sodium polyacrylate.

[0021] The present invention also provides a method for preparing a composition containing fruit acid and hydrolyzed collagen zinc, comprising the following steps:

[0022] (1) Mix the raw materials of phase A, heat to 82-84° C., and stir to obtain a phase A mixture;

[0023] (2) Mix the raw materials of phase C, heat to 76-78° C., and stir evenly to obtain a phase C mixture. Add the phase C mixture to the phase A mixture, stir evenly, and obtain a phase A and phase C mixture;

[0024] (3) The raw materials of phase B and phase D are mixed uniformly to obtain a phase B mixture and a phase D mixture respectively, the phase A and phase C mixture are cooled to 42-44° C., the phase B mixture and the phase D mixture are added in sequence, and the mixture is stirred uniformly to obtain a composition containing fruit acid and hydrolyzed collagen zinc.

[0025] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0026] 1. The present invention provides a composition containing fruit acid and hydrolyzed collagen zinc and a preparation method thereof. Through the compounding of multiple raw materials and synergistic enhancement, the skin can be moisturized and whitened, and the skin can be made firmer and smoother. Mandelic acid has the best lipophilicity among fruit acids, can treat pore blockage caused by oil, and has good ability to penetrate the epidermis. Lactobionic acid, as a third-generation fruit acid, has eight groups of hydroxyl water bases, can capture a large number of water molecules and has high moisturizing properties, and has a protective and soothing effect on inflamed skin. Malic acid can accelerate the metabolism of skin keratin without irritating the skin, and can therefore be used as a penetration enhancer and a booster for functional ingredients. During use, subsequent use with other functional products can promote the penetration and absorption of product ingredients and enhance efficacy, and can be used with ingredients such as niacinamide, retinol, and vitamin C. At the same time, hydrolyzed collagen zinc is used, which is a perfect combination of hydrolyzed collagen and zinc, and has the effects of both. At the same time, hydrolyzed collagen can also increase the bioavailability of zinc. Hydrolyzed collagen not only has the effect of filling the deep skin and supporting the skin from the inside, but zinc also plays an important role in promoting wound healing, treating acne, and reducing inflammation.

[0027] The composition of the present invention is a skin care system that integrates the functions of oil control, soothing, removing spots, solving dull and yellowing, repairing, and refining skin, and can enhance the skin's ability to intelligently regulate oil secretion and help the skin rebuild its barrier. The present invention adds three acids and one zinc, which has significant advantages in use compared to a single fruit acid, and the composition of the present invention is more suitable for Asian skin with a thin stratum corneum.

[0028] 2. When the total amount of the three fruit acids added exceeds 6%, the oil control effect is better, but it may cause irritation to the skin. Therefore, the inventors added a specific proportion of polyols and kava leaf rhizome extract to the system, and the combined use can show a synergistic effect of reducing the irritation of the three fruit acids.

[0029] 3. The present invention adds an emulsifier of fatty alcohol polyoxyethylene ether AEO-15, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane to the system to improve the stability of the composition. When fatty alcohol polyoxyethylene ether AEO-15, lauryl PEG-9 polydimethylsiloxyethyl polydimethylsiloxane and cetyl PEG / PPG-10 / 1 polydimethylsiloxane are compounded in a specific ratio, the storage stability under variable temperature conditions is also improved.
