The invention relates to the field of cosmetics and in particular relates to eye gel. The eye gel is prepared from the following components in percentage by weight (%): 11 percent to 12 percent of 1,3-butanediol, 3.5 percent to 5 percent of glycerol, 6 percent to 7 percent of glycerol acrylate / acrylate copolymer, 9 percent to 10 percent of propylene glycol, 7.5 percent to 9 percent of a PVM / MA copolymer, 3 percent to 5 percent of sodium hyaluronate, 2 percent to 4 percent of carbomer, 2.5 percent to 3 percent of sclerotium gum, 5 percent to 6 percent of triethanolamine, 4 percent to 5 percent of allantoin, 6 percent to 7 percent of methyl hydroxybenzoate, 13 percent to 14 percent of hydrogenated castor oil, 2 percent to 3 percent of polysorbate-20, 2 percent to 3 percent of imidazolidinyl urea, 1.5 precent to 3 percent of vitamin E and the balance of de-ionized water which is added until the total amount is 100. The eye gel provided by the invention is fresh and prone to absorb, does not cause any load on skins and can activate microcirculation of the skins around eyes so that the skins around the eyes are full of moisture; the eye gel can be used for enabling a skin color to be even, improving a dark phenomenon of the eyes, reducing edema of the eyes, fading black eyes and reducing dry wrinkles and under-eye puffiness of the eyes. The eye gel has the effects of alleviating a fatigue feeling, enabling the skins to recover elasticity and be compact and perfect, and molding the eyes which are revitalized and are bright. The eye gel also has the effects of keeping moisture, diminishing inflammation and the like, and is suitable for various skin types to use.

The invention relates to a preparation method of a submicron emulsion repairing stock solution composition and a cosmetic composition containing the submicron emulsion repairing stock solution composition. The submicron emulsion repairing stock solution composition is prepared from oligopeptide-3, oligopeptide-1, Indolicidin or an analogue thereof, Cathelicidin-BF, hyaluronic acid, glycerol, minkoil, lecithin, starch sodium octenylsuccinate, fatty alcohol polyoxyethylene ether, hydroxyethyl cellulose, propylene glycol / bis(hydroxymethyl)imidazolidinyl urea / methylparaben / iodopropynyl butylcarbamate and the like. A submicron emulsion repairing stock solution has the effects of keeping moisture and repairing, resisting bacteria and removing acnes. The repairing stock solution composition canbe used for promoting growth and cracking of various cells in epidermal tissues, promoting the growth of collagen, repairing aged collagen elastic fibers and recovering skin activity; especially, thesubmicron emulsion repairing stock solution composition has remarkable repairing effects on various epidermal wounds including acne marks, phototherapy, scalds and the like.

The invention relates to preservative systems which are particularly suitable in cosmetic and dermatological preparations. The preservative system which comprises a cationic surfactant, derived from the condensation of fatty acids and esterified dibasic amino acids, having the formula (I) where: X− is Br−, Cl−, or HSO4 R1: is a straight alkyl chain from an acid or saturated fatty hydroxy acid from 8 to 14 atoms of carbon bonded to the α-amino acid group through amidic bond. R2: is a straight or branched alkyl chain from 1 to 18 carbon atoms or aromatic. R3: is: (II) where n can be from 0 to 4, is combined with at least one other ionic or non-ionic preservative agent, whereby the combination displays a synergetic activity. A preservative system, wherein the cationic surfactant preservative derived from the condensation of fatty acids and esterified dibasic amino acid is LAE is particularly preferred. The other ionic or non ionic preservative agent is preferably at least one component selected from the group consisting of 2-bromo-2-nitro-1,3-propanediol (bronopol), parbens, imidazolidinyl urea, phenoxyethanol, DMDM hydantoin, 2-methyl-5-chloro-3,4-isothiazolinone / 2-methyl-3,4-isothiazolinone and quaternium-15.

The invention discloses a ginseng skin whitening facial mask comprising the following components in percentage by mass: 0.3-0.5% of ginseng root extract, 3.3-5.18% of butanediol, 0.34-0.524% of bis(hydroxymethyl) imidazolidinyl urea, 5-8% of glycerinum, 4-6% of propylene glycol, 1-3% of sodium ascorbyl phosphate, 0.2-0.4% of PEG-60 hydrogenated castor oil, 0.2-0.4% of hydroxyethyl cellulose, 0.05-0.15% of EDTA disodium, 0.05-0.15% of essence and the balance of water, wherein the ginseng root extract is used as a skin conditioning agent, sodium ascorbyl phosphate is used as a freckle removing agent, and EDTA disodium is used as a surfactant; therefore, the ginseng skin whitening facial mask has the functions of whitening skin of people, improving the skin elasticity and achieving the beautifying and skin care effects.
