Problems solved by technology

To solubilize some non-polar low oils, a large amount of non-ionic surfactants with high HLB values ​​are generally required for solubilization, but non-polar high oils such as phytosterols or their esters must be solubilized in water until transparent. It is difficult to make preparations such as toners, which often use a large amount of nonionic surfactants with a high degree of polymerization, but the solution is also difficult to be transparent, and skin penetration and absorption cannot be guaranteed.
In addition, the use of a large number of nonionic surfactants with a high degree of polymerization can cause stickiness and irritation to the skin

Abstract

The invention discloses a composition of solubilized phytosterol or ester, application of the composition and a cosmetic prepared from the composition. The composition contains the components of phytosterol or ester thereof, higher alcohol, a low-polymerization-degree PEG-structured nonionic surfactant, a high-polymerization-degree PEG-structured nonionic surfactant and low alcohol in a weight ratio of 1 to (1-3) to (2-5) to (2-5) to (60-120). The prepared composition of solubilized phytosterol or ester thereof is applied to low-alcohol and alcohol-free water-based cosmetics such as lotions, essences and facial masks and is capable of promoting the dissolving of effective skin components such as phytosterol or ester in water, supplementing the oil content of the skin and increasing moist degree of the skin, the sticky feel of skin is low, and the irritability of the skin is low; and the composition is applicable to most aqueous systems, and the stability of the systems is not influenced.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a composition for solubilizing phytosterol or its ester, its application and the cosmetic prepared therefrom. Background technique [0002] With the improvement of people's living standards, cosmetics have entered thousands of households, and people's demand for high-quality cosmetics is becoming increasingly severe. Due to needs, sometimes it is necessary to choose to add some oil-soluble substances such as oil, active substances, flavors, preservatives, etc. to the water-based system. However, under normal circumstances, these oil-soluble components are difficult to dissolve in the formulation system and cannot form a homogeneous phase. Therefore, solubilizers play a vital role in this type of cosmetics. Solubilizers can help oil-soluble ingredients dissolve in water and form a uniform and transparent homogeneous system. [0003] The components of solubilizers in the market are mainl...
