Description

Transparent lip glaze and preparation method thereof

Technical Field

The invention belongs to the field of cosmetics, and particularly relates to a transparent lip glaze and a preparation method thereof, in particular to a transparent lip glaze with good appearance visual effect and a preparation method thereof.

Background

The lip glaze belongs to one kind of lip makeup cosmetics, and is one kind of liquid lipstick with the features of moistening, glossy and easy painting. Two products, namely a water-oil system and a full-oil system, are mainly available in the market. The lip glaze of the water-oil system is divided into two layers of water and oil due to different specific gravity, so that oil and water are difficult to mix uniformly when the lip glaze is used, and the using effect is very poor; in addition, the water and the oil are incompatible, the time is required for recovering the water-oil two-layer state after the water-oil two-layer state is used, the water-oil interface is not clear, and the appearance vision is influenced. The lip glaze of the full-oil system can only be added with oil-soluble functional components generally, although the water-soluble functional components can be added in an emulsifying or solubilizing mode and the like, the appearance cannot be completely transparent, although some manufacturers wrap the water-soluble components by adopting a specific coating to prepare soft beads, and then add the soft beads into the full-oil system, the soft beads are often unstable under the condition of high temperature (above 40 ℃), and the shells of the soft beads are easily dissolved in the lip glaze of the full-oil system, so that the whole transparent system is turbid, and the appearance and the actual use are influenced. There is also a transparent lip glaze containing suspended substances on the market, which is not easy to break due to the over hard texture of the suspended substances, and the practical use effect is not good although the appearance is beautiful. On the other hand, most of the current cosmetic active ingredients are water-based, the selection of oil-soluble active ingredients is very few, and if only the oil-soluble active ingredients can be contained in the product, the market demand of product development is also limited.

CN111991248A discloses a lip glaze and a preparation method thereof, which comprises a volatile oily solvent, a softening agent, an emulsifier, an emulsion stabilizer, trimethylsiloxy silicate, a VP/hexadecane copolymer, a preservative, an adsorbent and a pigment. The preparation method comprises the following steps: mixing the volatile oily solvent with trimethylsiloxysilicate at normal temperature to obtain a first mixture; adding a softening agent, a VP/hexadecane diluted copolymer, other auxiliaries, an emulsion stabilizer, fumed silica and an adsorbent into the first mixture, and mixing to obtain a second mixture; adding the pigment into the mixture II and mixing to obtain a mixture III; grinding the mixture III; and adding vitamin E and a preservative into the ground mixture III, and mixing to obtain the lip glaze. The lip glaze can be applied to the lips of a user in daily life, and has the advantages of strong adhesive force and difficulty in adhering to other objects. But the appearance is not transparent, and water-soluble functional components cannot be added because the formula does not contain water.

CN110638691A discloses a paint mirror surface color-holding lip glaze and a preparation method thereof, which comprises the following components in percentage by weight: 20-80% of grease, 0.1-15% of oil-in-water emulsifier, 0.05-15% of colorant, 0.5-10% of oil phase film former, 0.5-20% of water phase film former and the balance of water. The paint gloss mirror surface color-holding lip glaze disclosed by the invention is an oil-in-water lip product, oil is an internal phase, and water is a continuous external phase, so that the greasy feeling of an oil paste product is well solved. Meanwhile, the oil phase film forming agent and the grease are mutually matched to realize a synergistic interaction effect, so that the glossiness, the persistence and the moistening degree of the lip glaze are greatly improved. However, the emulsion form of the emulsion causes the product to have a cloudy appearance, and has a limit on the promotion and commercial effect of the product.

At present, lip glaze has the problems of visual appearance, selection of functional components and use effect and is difficult to meet the market demand, so how to provide lip glaze which has good visual appearance effect and is convenient to use, and various oil-soluble and water-soluble functional components can be added randomly according to the market demand becomes a problem to be solved urgently.
