The present invention relates to preservation of cosmetic formulations. More specifically, the present invention relates to a preservative composition for cosmetic formulations comprising thymol, monolaurin and magnolol obtained from supercritical fluid extracts of Magnolia officinalis.

The invention discloses a method for preparing monolaurin, which comprises the following steps: taking camphor tree seed oil as a raw material; adding degumed and dehydrated camphor tree seed oil into an esterification and alcoholysis reactor, and adding acidic ionic liquid 1-methyl-3-(3-sulfopropyl) imidazole catalyst to reacting at the temperature of between 135 and 145 DEG C until the acid value is reduced to below 0.5, wherein the temperature the dosage of the catalyst is 3 to 4 percent of the weight of the oil and the molar ratio of the alcohol to the oil is 1.5-2.5:1; performing centrifugal separation, adding the esterified and alcoholized amphor tree seed oil into a catalysis and alcoholysis reactor, and adding the alkaline ionic liquid of 1-butyl-3-methyl imidazole salt to react at the temperature of between 165 and 175 DEG C until the total content of the monofatty glyceride is over 90.0 percent, wherein the dosage of the catalyst is 0.4 to 0.6 percent of the weight of the oil and the molar ratio of the alcohol to the oil is 6-7:1; performing centrifugal separation, washing with the water at the temperature of between 15 and 35 DEG C; and performing vacuum dehydration and decoloration. The monofatty glyceride content in the product is over 90.0 percent; the monolaurin content is over 85.0 percent; and the process of molecular distillation can be saved. The technology is reasonable, energy-saving and environment-friendly; and most of the glycerol can be recycled, and the discharge of acid, alkali and salt is greatly reduced.

The invention discloses a scar repair material. A preparation method comprises the following steps of: dissolving water-soluble chitosan in water or dissolving chitosan with the deacetylation degree of 75 to 97 percent in an acetic acid aqueous solution under stirring, adding polyoxyethylene sorbitan monolaurate with an emulsifying effect and glycerin with a moisturizing effect, and uniformly mixing to obtain a transparent gel-like solution; and adding polydimethylsiloxane into the gel-like solution under homogenizing, and uniformly mixing to obtain the scar repair material. The scar repair material can actively and passively moisture skin, has a hydration effect on scar skin, has a good repair effect, has an effect of resisting and inhibiting bacteria, has a good effect of resisting and inhibiting the bacteria on the surfaces of scars and outside the scars, has an effect of accelerating skin wound healing, can have a good effect of repairing and protecting fine cracks on the surfacesof the scars, and can inhibit the secretion of collagen type I in keloid skin to reduce the proportion of the collagen type I or collagen type III.

The invention relates to the technical field of washing salts, especially a novel green and environment-friendly fruit and vegetable washing salt. The washing salt comprises the following components by mass: 80-90 parts of sodium chloride, 1-6 parts of sodium citrate, 0.2-0.8 part of citric acid fatty acid glyceride, 0.5-1 part of polyoxyethylene sorbitan monolaurate, 4-8 parts of polyglucoside, and 2-8 parts of cocamidopropyl betaine. After use of the fruit and vegetable washing salt, ''oil-coated'' or ''water-coated'' macromolecules are easy to form, and are easily dispersed into the solution rapidly in an oscillation process, also the fruit and vegetable washing salt endows the surfaces of the fruits and vegetables with lubricity, thus greatly reducing the pesticides, oil and dustiness after adsorption washing, and preventing secondary pollution, the washing water is removed, and then the fruits and vegetables are rinsed clean with clear water.

The invention discloses a quercetin nanostructured lipid carrier and a preparation method thereof, wherein the quercetin nanostructured lipid carrier comprises the following components by weight percent: 0.1-1% of quercetin, 2%-15% of an emulsifying agent, 2%-15% of compound lipid material and the balance being water. The compound lipid material is a solid-liquid state lipid mixture; the solid lipid is one or more of acetylation monoglyceride, stearate, glyceryl monostearate and monolaurate; the liquid lipid is one or more of decanoyl / octanoyl-glycerides, camellia oleosa seed oil, soybean oil and peanut oil. The quercetin is loaded by utilizing a nanostructured lipid carrier technique, on the one hand, the sensibility of the quercetin to the environmental factors such as illumination and temperature can be reduced, and the chemical stability is improved, and on the other hand, the solubility of the quercetin in water can be improved, thereby improving the bioavailability. The preparation method is simple and controllable, and is good in reproducibility; the quercetin nanostructured lipid carrier emulsion prepared by the method is suitable for being added into functional food beverages.
