The content of the invention
In order to overcome shortcoming and deficiency existing in the prior art, primary and foremost purpose of the invention is to provide a kind of solubilising naturally
The composition of vegetable fat, said composition are applied in water system cosmetics, can make solution solubilising to transparent, and skin sticks soapy feeling
It is low, irritation is small.
The present invention is achieved by the following technical solutions:
A kind of composition of solubilising natural plant grease, includes component:Natural plant grease, higher alcohol, low polymerization degree band
There are PEG structures nonionic surfactant, high polymerization degree to carry PEG structures nonionic surfactant and lower alcohol, wherein, day
Right vegetable fat:Higher alcohol:Low polymerization degree carries PEG structure nonionic surfactants:High polymerization degree with PEG structures it is non-from
Sub- surfactant:The weight ratio of lower alcohol is 1:1-3:2-5:2-5:60-120.
The present invention selects tween not according to HLB value, but by being conceived to the polarity of water, oil components
The technical method found with the PEG degree of polymerization of nonionic surfactant.Oil components are natural plant grease, are nonpolar
Oil.However, the polarity highest of water, high polymerization degree is soluble easily in water with PEG structure nonionic surfactants, cannot but be dissolved in
Oil.The present invention carries PEG structures nonionic surfactant and height by the low polymerization degree added positioned at the rwo intermediate polarity
Level alcohol, becomes both compatible materials.In addition, being located at water plus polarity and high polymerization degree carries PEG structure nonionic tables
Lower alcohol between the activating agent of face, makes oil components in water can be solubilized to transparent.From the point of view of the chemical constitution of higher alcohol, its alkane
The end of base carries hydroxyl, and polarity is high in oil components.Low polymerization degree carries the polarity bit of PEG structure nonionic surfactants
Between the nonionic surfactant of higher alcohol and high polymerization degree with PEG structures, both are all solvable.The present invention passes through research
Higher alcohol, low polymerization degree are lived with PEG structures nonionic surfactant, high polymerization degree with PEG structures non-ionic surface
Property agent and lower alcohol be combined with oil components, and the amount of each component is controlled in certain proportion, make its into
, can be small scattered and solubilized to transparent by oil components for the intermediate polarity connectionist of water and oil components.
According to natural plant grease, higher alcohol, low polymerization degree with PEG structures nonionic surfactant, high polymerization degree
With the polar relationship between PEG structures nonionic surfactant and lower alcohol, respective ratio is selected as 1:1-3:2-5:2-
5:60-120.If low polymerization degree and high polymerization degree are very few with PEG structure nonionic surfactants, higher alcohol is excessive, that
Polarity of the high polymerization degree with PEG structure nonionic surfactants but cannot be soluble in height with the polarities match of water
In level alcohol, so that there is lamination, in addition it is muddy.If low polymerization degree and high polymerization degree carry PEG structure non-ionic surfaces
Activating agent is excessive, and higher alcohol is very few, then low polymerization degree with PEG structure nonionic surfactants polarity cannot with it is advanced
Alcohol polarities match, also occurs corresponding layering, or even muddy.
As the further preferred solution of the present invention, the composition of solubilising natural plant grease of the present invention, naturally
Vegetable fat:Higher alcohol:Low polymerization degree carries PEG structure nonionic surfactants:High polymerization degree carries PEG structure nonionics
Surfactant:The weight ratio of lower alcohol is 1:2:3-4:3-4:80-100.
