Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cleansing agent for hair and skin, and more particularly to a cleansing agent that is non-irritating and capable of keeping the skin in a smoother and milder state.

(Conventional technology) Skin cleansing mechanisms are well known and widely studied.

This problem is always faced with the use of chemicals with a cleaning action. The cleansing action is more or less strong and specific and causes non-negligible side effects such as dryness of the skin with conditions such as cracking, peeling, roughness and flushing. These problems not only affect aesthetic appearance, but also affect the natural protection of the skin.

Many attempts at complex formulations have been made over the years. For example, in addition to ingredients that have a cleansing effect, attempts have been made to include other ingredients such as emollients that can reduce the roughness of the skin due to cleaning. Typical examples include phosphorus and other animal oils, vegetable oils, mineral oils, etc., which are present in appropriate proportions in the detergent in solid or liquid form. Another common method is pH adjustment to neutralize the cleaning agent.

It has already been proposed to use oily mixtures as cleansers and cosmetics for the protection of the skin and hair. In traditional methods, these compositions were rubbed into the skin and/or hair and then removed. A surfactant or emulsifier was added to the composition to facilitate removal of the composition when rinsed with water.

As a result, these compositions are conventionally rubbed into the skin and/or hair, allowed to remain in contact with the skin and/or hair for some period of time, such as several minutes or more, and then rinsed with water to remove the emulsifier. It took advantage of the fact that the presence of the compound forms an emulsion so that the composition can be more easily removed.

In the pediatric field, oil-based compositions have been used that are rubbed onto napkin-covered areas of the body to balance the effect of soaking up body fluids and excreta. This is because infants' skin is too delicate to withstand the cleaning action of even the mildest soaps. In this regard, it is useful to briefly outline the characteristics and main properties of the lipid film or sebum that coats the skin. It is a hydrophilic, homogeneous, finely emulsified layer with important protective functions. The lipid film is produced directly or by appropriate sebaceous glands on the skin surface throughout the life of the body, varying in amount and composition. Sebum is often produced in excess of what the skin needs (seborrhea), or in an insufficient amount (fat-deficient skin, alipic skin).
5kin). In both cases, skin diseases, abnormalities, changes, and defects are caused, and the importance of sebum and its biological role are recognized. In fact, sebum protects the skin from airborne pollutants, skin sweat, dehydration, and sudden temperature changes. It also provides a surface shield against chemically active substances, preventing contact with the skin and absorption thereof.

It also serves as a carrier for vitamin D precursors and exhibits anti-infective activity against some pathogenic microorganisms.

Finally, sebum has a lubricating, softening and relaxing effect, making the skin soft and plump and preventing excessive evaporation of surface moisture.

Sebum contains triglycerides, free fatty acids, waxes, sterols, their esters, alcohols, hydrocarbons (typical examples are squalane), and non-negligible amounts of vitamins (mainly provitamin D1, vitamins A and E).
It is a semi-solid lipid mixture consisting of

Because sebum contains cholesterol and its esters,
Forming a water-in-oil emulsicin, it retains moderately hydrating but non-dispersing lipid properties and is not removed from the skin by water alone.

Cleansing the skin means removing sebum, waste products, and dirt;
It's not a physiological effect. In most cases, the protective layer of lipids mentioned above is also removed. However, skin cleaning is necessary not only to remove dirt and the like, but also to remove part of the sebum layer, that is, the old sebum layer. Fact-1: Sebum often undergoes chemical changes due to oxygen in the air and microorganisms present on the skin, causing irritation to the skin. In view of the above, there has been a demand for the development of a means for efficiently removing dirt, waste, and a portion of sebum (without removing the entire sebum layer) from the skin without irritating the skin.

From this point of view, apart from the soaps and cleaning agents that have the above-mentioned drawbacks, so-called cleaning milk is also said to be insufficient in its cleaning action in terms of partially removing sebum and removing makeup and dirt. It wasn't appropriate for some reason.

(Problems to be Solved by the Invention) An object of the present invention is to provide a cleaning agent that eliminates the above-mentioned conventional drawbacks.

(Means for Solving the Problems) The present invention relates to a cleaning agent which further contains at least one selected from the group of animal oils, vegetable oils, mineral oils and synthetic oils and at least one emulsifier.

One of the essential ingredients of the compositions of the invention is an oil or a mixture of oils. Examples of oils used in the present invention include petrolatum oil, mineral oils such as silicone oil, almond oil, corn oil, olive oil, walnut oil, soybean oil, grape oil, sesame oil, peanut oil, coconut oil, avocado oil, Vegetable oils such as sunflower oil, corn oil and castor oil; animal oils such as turtle oil, mink oil, marmot oil and lanolin oil; and synthetic oils known in the cosmetic field. Examples of synthetic oils include isoprobyl myristate, palmitate and stearate, octyl dodecyl, decyl oleate, isostearic acid derivatives, diisopropyl adipate, myristyl lactate, and the like.

The oil can be replaced at least in part by vegetable gelatin, in which case the density of the detergent according to the invention can be adjusted. The proportion of the oil or mixed oil in the composition is preferably 80 to 98% by weight, and an order of 90% by weight is particularly preferable.

Another essential component of the composition of the present invention is an emulsifier selected from anionic, cationic,/ionic or amphoteric emulsifiers which is soluble in the above-mentioned oil. Examples of emulsifiers used in the present invention include aliphatic alcohol sulfates or derivatives thereof, quaternary ammonium compounds or derivatives thereof, amino acids, betaine derivatives, fatty acids or alcohols condensed with ethylene oxide, sucrose esters, polyethylene Alternatively, polyoxypropylene derivatives and the like can be mentioned.

As is generally known, emulsifiers do not have any cleaning effect, and in principle the combination of oil and emulsifier does not have any cleaning effect. However, in the present invention, surprisingly,
It has been found that when this combination is combined with water before being applied to the skin, it acts as a soap and has the excellent effect of removing only a portion of the sebum on the skin. In the present invention, the proportion of the emulsifier in the composition is preferably 2 to 20% by weight. Also, small amounts of emulsifiers can be replaced by conventional surfactants.

When saccharose ester is used as one of the main emulsifiers of the present invention, it exhibits a synergistic effect with one or more other emulsifiers in the composition, making the resulting emulsion silane finer and softer. And make it fluid.

This was confirmed through experiments using the composition of the present invention, which consists of an oil component and an emulsifier component. A sucrose ester selected from saccharose monolaurate, monopalmitate, monostearate and distearate was added to the composition in a proportion of 0.5% by weight. The composition of the comparative composition was 72% mineral oil, 25% soybean oil, and 3% polyoxyethylene oleyl ether. The results are shown in Table 1 below. The transparency (T) of the emulsion at 650 nm at several dilution levels is shown.

Table 1 As is clear from the transparency in Table 1, the turbidity of the oil-in-water emulsion increases in all cases with the addition of sucrose ester, which leads to a considerable increase in milk viscosity and detergent action.

The concentration of sucrose ester in the composition is preferably 0.05 to 2% by weight.

In the present invention, bentonite and montmorillonite type powdered clay minerals can be further added to the composition.
This allows you to control the thickness of the lipid layer that remains on the skin after rinsing with water. In particular, when the clay powder content is 0.5-1.5% by weight in the composition, a more viscous lipid layer is obtained, and when the clay powder content is 1.5-10% by weight, a creamy layer is obtained. A layer of is left on the skin. In other words, when the clay powder is in the lower range, the skin feels soft and slightly greasy, and when it is in the upper range, it feels like there is a cream layer.

Furthermore, compositions of the present invention may be obtained which provide hydration and restorative properties as well as nourishing and energizing functions to the skin. For water conservation and restorative properties, hydrating agents such as glycerin, urea or amino acids that are sparingly soluble or insoluble in oil and do not suspend can be added to the composition, thereby allowing for the removal of natural water use substances by a cleansing action. Prevents skin dehydration.

Examples of amino acids are valine, isovaline, leucine,
Examples include isoleucine. Together with urea and glycerin they exhibit a revitalizing effect. Also, vitamins A and E for their nutritional benefits.

Fat-soluble vitamins such as F can be added.

The composition of the invention can also be used as a hair shampoo. Known shampoos always remove too much sebum from the scalp and hair, leading to so-called reactive seborrhea, which becomes worse when the number of hair washes increases. When the composition of the invention is used as a hair shampoo, reactive seborrhea is prevented due to the absence of known cleansing ingredients and the fact that a sebum-like film remains in place of the removed natural sebum.

(Effect of the invention) The composition of the present invention has the following excellent features.

- Does not change the pH of the skin.

Does not affect the skin or irritate the eyes or mucous membranes.

- Has no allergic or photosensitizing effects.

- Removes all types of residues like lipid make-up from the skin.

Remove only the surface part of sebum.

-Does not leave any unpleasant residue on the skin.

- The lipid layer on the skin is not strongly attacked and the skin is safely protected from exfoliation due to brushing, etc.

From the description of the features of the present invention, it is clear that the composition of the present invention forms a milk-like emulsion in the presence of water, most of which is in the form of oil-in-water droplets and can be washed with water, but a small amount is an oil-in-water emulsion. It is in the form of water droplets, and the latter remains on the skin even after rinsing.
Shows protective effect. In fact, this layer replaces the removed sebum part and exhibits more important chemical-physical and biological properties, at the same time being stable against oxidizing agents and resistant to microbial attack.
