The water-resistant sunscreen composition with the water outlet capacity comprises the following components in percentage by weight: 8.00% ethylhexyl methoxycinnamate, 2.00% hexyl diethylamino hydroxybenzoyl benzoate, 1.50% bis-ethylhexyloxyphenol methoxyphenyl triazine, 3.00% homosalate, 9.50% zinc oxide, 2.00% phenethyl alcohol benzoate, 2.00% isononyl isononanoate, 2.00% cyclopentadimethylsiloxane, 0.50% polydimethylsiloxane and a mixture of polydimethylsiloxane/vinyl polydimethylsiloxane crosspolymer, wherein the second phase comprises 0.20% methylparaben, 0.10% propylhydroxybenzoate, 0.05% chlorphenesin, 3.00% butanediol, 2.00% glycerol, 0.10% xanthan gum, 0.60% sodium acrylate/sodium acryloyldimethyltaurate copolymer in the second phase, isohexadecane, 1.60% polysorbate-80 and water, 0.30% sodium acrylate/sodium acryloyldimethyltaurate copolymer in the third phase, and the balance water.
Provides a preparation method of a water-resistant sunscreen composition with water outlet capacity, which comprises the following steps: (1) Mixing and heating the components of the first phase to 85 ℃, and stirring until the components are completely dissolved to form the first phase, wherein the components of the first phase are ethylhexyl dimethoxycinnamate, hexyl diethylamino hydroxybenzoyl benzoate, bis-ethylhexyloxyphenol methoxyphenyl triazine, homosalate, zinc oxide, phenethyl alcohol benzoate, isononyl isononanoate, cyclopentadecyldimethyl siloxane, polydimethylsiloxane and a polydimethylsiloxane/vinyl polydimethylsiloxane cross-linked polymer mixture; (2) Heating deionized water to 70 ℃, adding methyl hydroxybenzoate, propyl hydroxybenzoate and chlorphenesin, adding dispersion of xanthan gum and butylene glycol after completely dissolving, then sequentially adding a mixture of glycerol, sodium acrylate/sodium acryloyldimethyl taurate copolymer, isohexadecane, polysorbate-80 and water, and uniformly stirring to obtain a second phase, wherein the dispersion of xanthan gum and butylene glycol is prepared by adding xanthan gum into a beaker filled with butylene glycol and uniformly stirring to obtain the dispersion of xanthan gum and butylene glycol; (3) Stirring at 80-85 deg.C, adding the first phase into the second phase, and homogenizing for 3-5min to obtain mixture; (4) And cooling the mixture to 60 ℃, adding a third phase, and uniformly stirring to obtain the water-resistant sunscreen composition with water yielding capacity, namely the light yellow water-condensed cream.
After the components in the water-resistant sunscreen composition with the water outlet capacity are compounded and prepared, the water-oil balance of the system can reach a critical state, if the emulsification is a little more, the water outlet feeling is not good, and if the emulsification is not sufficient, the composition system is not stable. When the water-oil equilibrium state is smeared, the water-oil equilibrium state has a water outlet feeling, and brings a cooling feeling to the skin. Water-oil balance is not realized by any component or preparation method, and the water-oil balance refers to that when the integral water phase and the integral oil phase are just emulsified and stable, the water-oil balance of the system can be realized by selecting, compounding and proportioning the composition in the patent. The water-resistant sunscreen composition with the water outlet capacity is a sunscreen cream designed by adopting a non-emulsifying idea, and the non-emulsifying concept means that a traditional emulsifier is not added, the traditional emulsifier is generally high in emulsifying capacity but large in irritation to a formula, and a high-molecular polymer emulsifier is added in the formula, so that the non-emulsifying concept can be said.
The zinc oxide is a zinc oxide flake, which is suitable for use in the composition. The flaky zinc oxide is uniformly dispersed in the composition, the critical state of the composition can enable the flaky zinc oxide to exert good effect, and the flaky zinc oxide can rapidly form a uniform zinc oxide film on the surface of skin when being spread, so that the film formed on the skin achieves the uniform sun-proof effect. Although water drops appear when the paint is applied to the skin, thereby bringing a cool feeling, the zinc oxide hydrophobic film formed on the surface of the skin has a good water-resistant effect.
The water-resistant sunscreen composition adopted by the invention does not need to add a film-forming agent, the cost is increased by adding the film-forming agent, the formula is simpler by not adding the film-forming agent, the simpler the formula is, the fewer chemical components are added, the safer the product is, and in addition, the air permeability of the skin can be increased and the irritation of the skin can be reduced by not adding the film-forming agent.
The water-resistant sunscreen composition with the water outlet capacity adopts three substances of methyl hydroxybenzoate, propyl hydroxybenzoate and chlorphenesin as preservatives, is suitable for the composition system, can ensure the stability of the system, and has influence on the stability of the system due to the use of other preservatives.
The water-resistant sunscreen composition with the water-yielding ability has the water-yielding ability because the formula just reaches the water-oil balance, and because the mixture of the high-molecular polymer sodium acrylate/sodium acryloyldimethyl taurate copolymer, isohexadecane, polysorbate-80 and water added in the formula has very low electrolyte resistance, electrolyte-containing components such as sweat and the like can be secreted on the skin, and when a material body is smeared on the skin, the viscosity of the material body can be rapidly reduced, and the phenomenon of water melting occurs, namely the water-yielding ability in the formula. The water resistance of the formula is due to the addition of the flaky zinc oxide, and the film-forming agent is not required to be added, and the flaky zinc oxide is also added, so that other systems such as a common oil-in-water system added with a traditional emulsifier can only be added with the film-forming agent or other substances with strong hydrophobicity to achieve the water resistance.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
