Description

Submicron vaseline composition and submicron vaseline bath essence

Technical Field

The invention relates to the field of bath cleaning, in particular to a submicron vaseline composition and a submicron vaseline bath essence.

Background

The shower gel is a daily chemical product necessary for daily life at present, has strong degreasing power and can remove grease on the surface of human skin. However, with the continuous improvement of the skin health requirements of consumers, the requirements of people cannot be met only by strong degreasing and cleaning capabilities. At present, most of body wash contains soap base components, so that the skin is easy to dry after washing, and particularly, the body wash is more obvious in winter.

Currently, to reduce the instances of dry skin, the soap-based component is generally reduced. However, the bath cream has weak degreasing power, cannot be washed cleanly, and the oil on the surface of the skin begins to be secreted after the bath cream is washed for a short time, so that the skin is quickly oiled. The existing bath lotion is difficult to satisfy the requirements of cleaning ability and skin moisture retention and moistening at the same time, so that further improvement is needed.

Disclosure of Invention

In order to obtain the shower gel which can wash clean skin and moisten the skin, the application provides a submicron vaseline composition and a submicron vaseline bath essence.

In a first aspect, the present application provides a submicron petrolatum composition, which comprises the following components in parts by weight:

16-36 parts of a surfactant;

3-10 parts of submicron vaseline emulsion;

1-7 parts of a skin conditioner;

the surfactant at least comprises 5-15 parts of sodium laureth sulfate, 3-10 parts of sodium laureth sulfate, 0.5-3 parts of sodium laureth-6 carboxylate, 0.5-3 parts of laureth-6 carboxylic acid and 1-4 parts of sodium cocoyl methyl taurate.

In order to have better cleaning capability, the skin-care product is prepared by matching sodium laureth sulfate and sodium laureth sulfate, but the skin drying is easily caused by the two components, and the moisturizing capability is poor. Therefore, the inventor firstly wants to add submicron vaseline emulsion to achieve the effects of moistening and moisturizing, but in experiments, the submicron vaseline emulsion is layered in sodium laureth sulfate and sodium laureth sulfate, is difficult to adhere and stay on the skin after use, is difficult to wash away water, and is difficult to achieve the effects of moistening and moisturizing. With further research, sodium cocoyl methyl taurate, sodium laureth-6 carboxylate and laureth-6 carboxylic acid are added into sodium laureth sulfate, sodium laureth sulfate and submicron vaseline emulsion in a specific ratio, so that the submicron vaseline emulsion can be uniformly dispersed in a system, the foam density of foam in the bath milk is changed, the mildness of cleaning components is increased, and the skin moistening degree is increased, so that the vaseline bath milk can clean and moisten the skin.

Preferably, the sodium laureth sulfate is 7-12 parts, the sodium laureth sulfate is 5-8 parts, the sodium laureth-6-carboxylate is 1-1.5 parts, the laureth-6-carboxylic acid is 1-1.5 parts, and the sodium cocoyl methyl taurate is 1.5-3 parts.

Further researching the proportion of each component in the system, the composition matched according to the proportion is applied to the shower gel, so that the cleaning capacity and the moisturizing capacity of the shower gel are further enhanced.

Preferably, the surfactant further comprises 0.5-2 parts of cocamidomethyl MEA and 1-4 parts of cocamidopropyl betaine.

Since the emulsion of vaseline is uniformly dispersed in the system, it is known that vaseline has a strong moisturizing property, is a mineral wax, is not easily absorbed by the skin, and forms a protective film on the skin surface, which makes the skin slightly sticky. In order to make the skin fresh and smooth after use, the inventors further studied and found that a pleasant feeling can be imparted to the skin by adding cocamidomethyl MEA and cocamidopropyl betaine.

Preferably, the skin conditioner is prepared by compounding 0.5-3 parts of hydroxypropyl starch phosphate, 0.1-2 parts of allantoin, 0.25-0.4 part of plant extract and 0.1-0.6 part of vegetable oil; the plant extract at least comprises 0.1-2 parts of chamomile hydrolat, and the plant oil at least comprises 0.06-0.4 part of soybean oil.

Preferably, the plant extract further comprises 0.05-0.3 part of purslane extract, and the plant oil further comprises 0.04-0.2 part of shea butter.

The skin conditioner composed of the components forms a natural protective film on the surface of skin after use, enhances the cuticle of the skin, improves the moisturizing effect, softens keratin, further improves the effect of moisturizing the skin, and improves the smoothness of the skin.

In a second aspect, the application provides a submicron vaseline bath essence emulsion, which is prepared from the following components in percentage by weight:

1 to 2.4 percent of thickening agent;

0.3 to 3 percent of other auxiliary agents;

water is added to 100%;

the other auxiliary agents comprise one or more of preservative, pH regulator, chelating agent and essence.

Preferably, the thickener is a mixture of acrylic acid/C10-30 alkanol acrylate crosspolymer, xanthan gum and guar gum hydroxypropyltrimonium chloride in a ratio of 1: (0.5-3): (0.1-20) in proportion.

Preferably, the mass ratio of the acrylic acid (ester)/C10-30 alkanol acrylate cross-linked polymer to the xanthan gum and the guar gum hydroxypropyl trimethyl ammonium chloride is 1: (1-2.5): (4-10).

In the submicron Vaseline composition system, in order to enhance the stability of the system and ensure that the components are not easy to separate after being placed in a bathroom humid environment for a long time, the aim is achieved by adjusting the formula of the thickening agent.

Preferably, the rest auxiliary agents comprise 0.05-0.3% of preservative, 0.06-0.5% of pH regulator, 0.05-0.3% of chelating agent and 0.1-0.5% of essence, wherein the preservative accounts for the total mass of the submicron vaseline bath essence; the preservative is prepared by compounding methyl chloroisothiazolinone, methyl isothiazolinone, magnesium chloride and magnesium nitrate, wherein the pH regulator is prepared by mixing citric acid and sodium hydroxide in a ratio of 1: (1.5-5) in a mass ratio.

In a third aspect, the application discloses a preparation method of submicron vaseline bath essence, which comprises the following steps:

step 1), stirring water and hydroxypropyl starch phosphate to homogenize to obtain a first mixture;

step 2), sequentially adding an alkaline regulator, xanthan gum, a chelating agent, allantoin, sodium laureth sulfate and sodium laureth sulfate in the pH regulator into the first mixture, heating to 60-80 ℃, and stirring until the mixture is dissolved to obtain a second mixture;

step 3), adding water to the second mixture to pre-soak the acrylic acid (ester)/C10-30 alkanol acrylate cross-linked polymer, and uniformly stirring to obtain a third mixture;

step 4), sequentially adding the cocoamide methyl MEA, the shea butter and the soybean oil into the third mixture, and stirring for more than 30min at the constant temperature to obtain a fourth mixture;

step 5), dispersing guar hydroxypropyl trimethyl ammonium chloride uniformly with water in advance, adding the dispersed guar hydroxypropyl trimethyl ammonium chloride into the fourth mixture, adding an acidic regulator in the pH regulator, and stirring uniformly to obtain a fifth mixture;

step 6), cooling the fifth mixture to 50-55 ℃, sequentially adding cocoyl methyl sodium taurate, sodium laureth-6 carboxylate, laureth-6 carboxylic acid and cocamidopropyl betaine, and uniformly stirring to obtain a sixth mixture;

and 7), cooling the sixth mixture to 38-42 ℃, sequentially adding the submicron vaseline emulsion, the preservative, the purslane extract, the chamomile hydrosol and the essence, and uniformly stirring to obtain the submicron vaseline bath essence emulsion.
