Description

Technical Field

[0001] The invention belongs to the technical field of daily cosmetics, and particularly relates to an alcohol-free, wash-free, fluffy hair spray composition and a preparation method thereof. Background Art

[0002] As a typical aerosol product, hair volumizing spray quickly absorbs oil from the hair, leaving the user's hair fluffy and smooth without washing. Existing hair volumizing sprays all use alcohol as a solvent. Alcohol's rapid evaporation, good compatibility with hydrophobic powders, and uniform dispersion ensure that the core adsorbent in the product is evenly distributed after spraying and retains its oil-absorbing properties once attached to the hair. However, alcohol as a solvent can directly or indirectly cause side effects such as scalp irritation and sensitivity. Chinese patent CN201810871215.9 discloses a hair dry cleaning composition and its preparation method, which is used to clean the hair in dry cleaning mode, but denatured ethanol is still used therein, and the dry cleaning mode cannot completely avoid contact with the scalp, so the use of the composition will still cause inevitable irritation to the scalp; Chinese patent CN 112156041 A discloses a hair dry cleaning spray composition and its preparation method, which uses silicon powder, starch, etc. as oil-absorbing powder, and adds ammonium cationic surfactants, and adds persimmon (DIOSPYROS KAKI) fruit extract and soapberry (SAPINDUSMUKUROSSI) fruit extract as natural deodorants, but the composition still uses ethanol as a solvent, which irritates the scalp. Therefore, the development of an alcohol-free hair wash-free fluffy spray not only brings convenience to human daily life and high safety, but can also effectively improve scalp health problems, control oil secretion, and alleviate scalp and hair problems such as hair loss. Summary of the Invention

[0003] In response to the problems existing in the prior art, the present invention proposes an alcohol-free, wash-free, fluffy hair spray composition and a preparation method thereof. The composition has the effect of making hair refreshing and fluffy, prevents hair from turning gray after use, and does not cause side effects such as scalp irritation and sensitivity. It is safe and reliable and suitable for a wide range of people.

[0004] In a first aspect, the present invention provides an alcohol-free hair leave-in fluffy spray composition, comprising a polyol, isododecane, silica, aluminum starch octenylsuccinate, HDI / trimethylol hexyllactone crosspolymer, methyl methacrylate crosspolymer, polymethylsilsesquioxane, rice (ORYZA SATIVA) starch, fragrance, and a propellant.

[0005] Furthermore, the alcohol-free hair wash-free fluffy spray composition comprises, by mass percentage, 0.1-15% of polyol, 0.1-15% of isododecane, 0.1-5% of silica, 0.1-5% of aluminum starch octenylsuccinate, 0.1-5% of HDI / trimethylol hexyllactone crosspolymer, 0.1-5% of methyl methacrylate crosspolymer, 0.1-5% of polymethylsilsesquioxane, 0.1-5% of rice (ORYZA SATIVA) starch, 0.01-0.5% of fragrance, and 70-95% of propellant.

[0006] Furthermore, the mass addition ratio of the polyol to isododecane in the alcohol-free hair wash-free fluffy spray composition is 0.1-15:0.1-5.

[0007] Furthermore, in the alcohol-free hair wash-free fluffy spray composition, the mass addition ratio of HDI / trimethylol hexyl lactone cross-polymer, methyl methacrylate cross-polymer, and polymethylsilsesquioxane is 0.1-1:0.5-1:1-2.

[0008] Furthermore, the polyol is isopropyl alcohol.

[0009] Furthermore, the propellant is propane and butane.

[0010] In a second aspect, the present invention provides a method for preparing an alcohol-free, leave-in hair volume spray composition, comprising the following steps:

[0011] S1. In a reactor, first mix isopropyl alcohol and isododecane and stir evenly;

[0012] S2, then adding silica, aluminum starch octenylsuccinate, HDI / trimethylol hexyl lactone crosspolymer, methyl methacrylate crosspolymer, polymethylsilsesquioxane and rice (ORYZA SATIVA) starch to the reactor in step S1, stirring and dispersing them evenly;

[0013] S3, then add the essence to the reactor in step S2, stir and mix evenly, and the basic liquid is completed;

[0014] S4. Fill the base liquid into the aerosol can, then place the aerosol valve, seal it, fill it with propane and butane, test it in a water bath, code the bottom of the can, install the nozzle, install the outer cover, and pack it into the box.

[0015] Furthermore, the alcohol-free hair wash-free fluffy spray composition includes, by mass percentage, 0.1-15% of isopropyl alcohol, 0.1-15% of isododecane, 0.1-5% of silica, 0.1-5% of aluminum starch octenylsuccinate, 0.1-5% of HDI / trimethylol hexyllactone crosspolymer, 0.1-5% of methyl methacrylate crosspolymer, 0.1-5% of polymethylsilsesquioxane, 0.1-5% of rice (ORYZA SATIVA) starch, 0.01-0.5% of fragrance, and 70-95% of propane and butane.

[0016] Furthermore, in the steps S1 to S4 of the method for preparing the alcohol-free hair wash-free fluffy spray composition, the mass addition ratio of isopropyl alcohol to isododecane is 0.1-15:0.1-5.

[0017] Furthermore, in the preparation method of the alcohol-free hair wash-free fluffy spray composition, the mass addition ratio of HDI / trimethylol hexyl lactone crosslinked polymer, methyl methacrylate crosslinked polymer, and polymethylsilsesquioxane in steps S1 to S4 is 0.1 to 1:0.5 to 1:1 to 2.

[0018] The core components of the foam-type hair oil-control, wash-free, fluffy aerosol composition prepared by the present invention include an adsorption component compounded from silica, aluminum starch octenylsuccinate, HDI / trimethylol hexyl lactone crosspolymer, methyl methacrylate crosspolymer, polymethyl silsesquioxane, and rice (ORYZA SATIVA) starch. The optimal adsorption rate and oil absorption value are achieved by adding specific amounts of the composition. When used, the composition can achieve a refreshing and fluffy feel after oil absorption without causing dullness or dryness due to excessive adsorption. Furthermore, the HDI / trimethylol hexyl lactone crosspolymer, methyl methacrylate crosspolymer, and polymethyl silsesquioxane components can provide a smooth feel after use.

[0019] The composition of the present invention uses isopropyl alcohol and isododecane as solvents to replace alcohol. Isopropyl alcohol has physical and chemical properties very similar to those of ethanol, but is not as negatively perceived by consumers as ethanol. Isododecane is a volatile oil with lower volatility than ethanol, but is far less irritating to the skin than ethanol and isopropyl alcohol. Furthermore, the present invention verifies through experiments that the adsorption effect of rice starch is significantly increased when isopropyl alcohol and isododecane are used as solvents and added in a specific ratio. In particular, the adsorption effect of rice starch is significantly promoted, thereby achieving unexpected results.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The foam-type hair oil-control, wash-free, fluffy aerosol composition of the present invention has a long-lasting oil-control effect. Compared with traditional rinse-off shampoos, the oil-control ingredients can work better and last longer, and are suitable for a wide range of people.

[0022] (2) The foam-type hair oil-control, wash-free, fluffy aerosol composition of the present invention can absorb the oil on the hair after use, making the hair refreshed and fluffy. Compared with common spray types, it has the advantages of less powder, no whitening of hair after use, and no risk of inhalation.

[0023] (3) This product does not contain ethanol in its formula, and after using the product, it can avoid skin sensitivity problems such as itching caused by irritation to the scalp.

[0024] (4) This product does not contain ethanol in its formula, which has lower safety risks and lower requirements for the production environment. DETAILED DESCRIPTION
