The invention discloses a composition for increasing the sunscreen value of a sunscreen
emulsion and a preparation method of the composition. Water, octyl polymethylsiloxane, ethylhexyl triazinone, diethylaminohydroxybenzoyl hexyl benzoate, diethylhexyloxyphenol methoxyphenyl
triazine, ethylhexyl methoxycinnamate, octocrilene, Tween 60 or
tribehenin PEG-20 ester or polyglycerol-3 diisostearate andglyceryl
stearate citrate combined components are adopted. A prepared
emulsion preform in a sub-micro
stable state is transferred into an ultrasonic
cell disruptor for treatment, a
treated water phase preform phase is added, homogenizing and uniform stirring are carried out to obtain a target product. According to the
emulsion prepared by the method, the usage amount of an emulsifier and a sunscreen agent can be reduced, the cost is saved, and the influence of large usage amount of the raw materials on
skin, such as
irritation, is reduced; The prepared emulsion is smaller in
liquid drop and more uniform in sunscreen component distribution, the sunscreen value of the sunscreen emulsion is increased, the
skin feeling is fresher, and meanwhile, the stability is better.
