Description

FIELD OF THE INVENTION The present invention relates to the field of cosmetics, and more particularly to cosmetic flowers and their color retention methods.

In recent years, along with the improvement of people's living standard, awareness of skin health care and development of science and technology, under the promotion of the idea of green, environmental protection, nature protection and natural return, natural plant cosmetics have been loved by consumers. There is. Compared with conventional cosmetics, the active ingredients of plants are natural substances, have smaller molecules, are easily absorbed by the skin, do not deposit in the body, and have no side effects when used for a long period of time. At the same time, under the promotion of the concept of natural plants, cosmetics with some plant petals added, such as petal water, petal masks and petal clinsin cream, have appeared in large quantities, so the activity of plant petals and new The beautiful appearance is preserved and extended to the maximum. As a beauty product, not only has a beauty effect due to the exertion of active ingredients, but also a psychological beauty effect due to psychological pleasure. The product of tangible rose petals with good morphology and color luster can give good visual enjoyment, and can give a cosmetic effect by stirring up the psychological pleasure of the consumer.

Existing petal freshness retention and color retention technology is often applied to the ornamental field, and in flower tea products, it may be related to the color retention of dried flowers. However, there are few products in which the whole flower is applied to cosmetics as it is, but it is often the case that the petals of fresh flowers are added directly, the treated dried flowers are added, or the fresh flowers are added after boiling in water. The effect of freshness retention and color retention in fresh flower cosmetics cannot be achieved.

In CN10268168A, a cosmetic product comprising putting dried petals in deionized water, heating at high temperature to sterilize, decolorizing with an aqueous solution of potassium hydroxide, adding to citric acid and stirring for 3 to 5 minutes, and then storing in an aqueous solution of preservative. A method for making petals is disclosed. This method uses dried petals as a raw material, the petals are easily crushed, they are not fresh, the active ingredient is severely washed away, and both high-temperature boiling and potassium hydroxide treatment cause severe decolorization of the petals, which makes it a cosmetic product. When applied, it cannot achieve the effect of freshness retention and color retention.

CN103263372A discloses a natural petal in which the natural petal is boiled with alcohol, boiled, and baked, and a cosmetic product using the natural petal. In this method, dried petals are used as a raw material, and the petals are practically subjected to secondary processing, so that the petals are largely damaged. The high temperature not only consumes energy, but also destroys the active ingredients with poor high temperature resistance in the petals of fresh flowers, and the dried petals after baking are easily damaged in the storage and transportation process and easily produce microorganisms, so cosmetics Poses a safety risk to.

As described above, the conventional technique has the following problems.
1. Since fresh flowers contain a large amount of water, mud and microorganisms, they tend to cause mold when applied.
2. Since a large amount of preservative is added to deal with mold, it has strong irritation and does not conform to the idea of green cosmetics.
3. Boiling fresh flowers with water leads to decolorization of petals and loss of corresponding color luster and activity, and addition of dry flowers causes petals to be brittle and fragile, spreading in oil system of cosmetics, and strong. The effect of being sexual cannot be achieved.
4. Since the petals are added alone, the petals tend to shrink during the addition process, and a good form cannot be maintained.

Therefore, by adding fresh flowers to all oil-based cosmetics, it is possible to maintain the characteristics such as the complexion and shape of flowers, and to research the method of retaining the color of cosmetic flowers to have an extremely large market value and wide application prospect. Being developed.

In view of the deficiencies of the prior art and the actual needs, the present invention optimizes the process flow, selects and uses the appropriate concentration of color protection solution and dissolution solution, and the synergistic action of each step results in fresh flowers.
