Embodiment 1
[0023] This embodiment provides a kind of rose hydrosol comprising antiseptic system, wherein said antiseptic system comprises: polyaminopropyl biguanide 2wt%, cetylpyridinium chloride 1wt%, p-hydroxyacetophenone 0.5wt%, propylene glycol 20wt%, The balance is water.
[0024] The preparation method of the antiseptic system is as follows: under the condition of 50-60°C, dissolve p-hydroxyacetophenone in propylene glycol, then add polyaminopropyl biguanide and cetylpyridinium chloride in sequence, fully dissolve and mix, and obtain the antiseptic system.
[0025] The preparation method of described rose pure dew comprises:
[0026] Step 1. Put the rose petals and water into the distillation kettle after mixing, and carry out distillation extraction under the condition of 50-70°C;
[0027] Step 2, passing the mixture produced by distillation into a condenser for condensation treatment to obtain a distillate;
[0028] Step 3, passing the distillate obtained in step 2 into the oi...
Embodiment 2
[0031] The difference between this embodiment and embodiment 1 is:
[0032] (1) The antiseptic system includes: polyaminopropyl biguanide 1wt%, cetylpyridinium chloride 0.5wt%, p-hydroxyacetophenone 0.3wt%, 1,2-butanediol 10wt%, and the balance is water.
[0033] (2) When the temperature of the pure dew is at 10-15° C., add the above-mentioned anti-corrosion system of 6 wt % of the total mass of the pure dew.
Embodiment 3
[0035] The difference between this embodiment and embodiment 1 is:
