In order to realize the purpose, the invention adopts the technical scheme that:

an emulsified lipstick comprises emulsifier, humectant, emollient and colorant; the emulsifier comprises the following components in parts by weight: 1-8 parts of cetyl PEG/PPG-10/1 polydimethylsiloxane and 1-10 parts of polyglycerol-2 triisostearate.

The cetyl PEG/PPG-10/1 polydimethylsiloxane has the functions of lubricating and locking water, moistening the skin and slowing down the water loss of the skin. It also has good inclusion properties and can release active molecules, especially pigments, in a prolonged manner. It also has effects in caring skin, and making skin smooth and soft without generating sticky feeling.

The polyglyceryl-2 triisostearate has the function similar to castor oil, has good dispersion effect on pigment, and is suitable for color products such as lipstick. Meanwhile, the product has a certain moisturizing effect, so that the product has a certain moisturizing effect after contacting the skin.

A large number of experimental researches show that when cetyl PEG/PPG-10/1 polydimethylsiloxane and polyglycerol-2 triisostearate are matched in parts by weight, lipstick has high water content, good moisturizing property and is not greasy.

Preferably, the cetyl PEG/PPG-10/1 polydimethylsiloxane: polyglyceryl-2 triisostearate is 1: 2. When the cetyl PEG/PPG-10/1 polydimethylsiloxane and the polyglycerol-2 triisostearate are matched and used according to the proportion, the lipstick prepared by the formula has the highest water content, the best moisturizing property and no greasiness.

Preferably, the humectant comprises the following components in parts by weight: 1-15 parts of jojoba seed oil, 1-15 parts of argania spinosa kernel oil and 0.02-1 part of a composition of sodium hyaluronate, castor seed oil and hydrogenated castor oil.

Aralia SPINOSA (ARGANIA SPINOSA) kernel oil is a nut oil extracted from the fruit of the argan tree. The oil is rich in fatty acids, vitamin E, squalene, sterol, etc., and is commonly used for treating skin diseases. The argania spinosa kernel oil is important oil for cosmetics, can improve good nourishing property and skin feel, has good oxidation resistance to human bodies, can repair lipid barriers of the skin, and has a certain repairing effect on sensitive skin.

The INCI name for the combination of sodium hyaluronate, castor seed oil and hydrogenated castor oil is "sodium hyaluronate/castor seed oil/hydrogenated castor oil" and is sold under the trade name HYACOLOR. The HYACOLOR is prepared from micromolecular sodium Hyaluronate (HA) and vegetable oil by a special process, and the main functional component, namely the micromolecular HA is uniformly dispersed in the oil in a microsphere form, so that the water-soluble HA is perfectly applied to an oily formula, and the effects of moisturizing, repairing, lip plumping and the like are given to the skin.

Experiments show that the compounding of the jojoba seed oil, the argania spinosa kernel oil and the HYACOLOR has a synergistic effect in the aspect of moisture preservation, and the skin can be kept moist for a long time.

Preferably, the humectant comprises the following components in parts by weight: 5-10 parts of jojoba seed oil, 5-10 parts of argania spinosa kernel oil and 0.05-0.2 part of a composition of sodium hyaluronate, castor seed oil and hydrogenated castor oil. When the jojoba seed oil, the argania spinosa kernel oil and the HYACOLOR are compounded in parts by weight, the synergistic moisturizing effect is more remarkable.

Preferably, the humectant comprises the following components in parts by weight: 8 parts of jojoba seed oil, 7 parts of argania spinosa kernel oil and 0.1 part of a composition of sodium hyaluronate, castor seed oil and hydrogenated castor oil. When the jojoba seed oil, the argania spinosa kernel oil and the HYACOLOR are compounded in parts by weight, the synergistic moisturizing effect is most remarkable.
