Description

Soothing shower gel and preparation method and application thereof

Technical Field

The invention belongs to the field of daily chemicals, particularly relates to a relaxing shower gel and a preparation method and application thereof, and particularly relates to a mild moisturizing relaxing shower gel and a preparation method and application thereof.

Background

The bath lotion is also called bath foam and shower cream, is a liquid cleanser used in bath and is widely used by people. However, many shower gels have the problem of strong irritation and dry skin.

CN111603400A discloses a method and equipment for preparing mild shower gel containing honey extraction essence, which can prepare shower gel with excellent quality by material preparation, primary mixing, dissolution, secondary mixing, thickening, cooling and packaging, and combines honey extraction essence, sodium salt mixture, alkali additives, plant branch and leaf extracting solution, plant oil additives, essence, thickening agents and surfactants together to facilitate the mutual reaction among the raw materials, give full play to the functions of the raw materials, have mild performance and easy absorption, provide different cares for dry and sunburned skin, moisten skin, and improve the storage aging of the shower gel and the decontamination capability of the skin. However, the use of alkaline additives can damage the acidic environment on the skin surface and cause skin dryness.

CN108078803A discloses a deep moisturizing mild shower gel and a preparation method thereof, wherein the deep moisturizing mild shower gel comprises the following raw material components in percentage by weight: 9-15% of amino acid surfactant, 1-1.7% of thickening agent, 3-15% of humectant, pH regulator to make the pH value of the deep moisturizing mild shower gel be 7.3-7.9, and the balance of deionized water. The preparation method comprises the following steps: adding the thickening agent and the humectant into deionized water, stirring and mixing to form a viscous liquid, then adding the amino acid surfactant, adding the pH regulator, and uniformly mixing to obtain the water-soluble thickener. The shower gel disclosed by the invention has the advantages of deep moisture retention, strong cleaning capability, easiness in washing, no residual feeling after washing, skin moistening and smoothness. However, the difference between the pH value of the skin and the pH value of the surface of the skin may damage the pH environment of the skin, thereby causing skin damage.

CN105878056A discloses a mild and moist soap-based shower gel, and belongs to the field of daily chemicals. The mild and moist shower gel comprises the following raw materials in percentage by weight: 10-30% of fatty acid, 0-8% of mild anionic surfactant, 0-6% of mild nonionic surfactant, 0-5% of mild amphoteric surfactant, 10-40% of polyhydric alcohol, 4-8% of potassium hydroxide, 1-2% of glycol distearate, 0.3-2% of thickening agent, 0.05-0.15% of EDTA-4Na, 2-5% of natural oil, 0.1-0.5% of preservative, 0.2-0.8% of essence and the balance of water. According to the invention, the mild surfactant is added into the soap base, the content of the polyalcohol is increased, and the natural oil is added to reduce the stimulation of the soap base to the skin, so that the effects of mild cleaning, deep moisture retention and moistening are achieved. But the adoption of potassium hydroxide can obviously increase the pH value of the shower gel, thereby causing skin damage.

The bath cream on the market at present has the problems of strong irritation and skin damage. Therefore, how to provide the shower gel which is mild, does not irritate and can relieve the skin becomes a problem to be solved urgently.
