Description

A liquid personal cleansing composition which can suspend particles stably}

The present invention relates to a whole body human cleanser composition capable of stably floating insoluble particles. More specifically, the human cleanser composition stably floats insoluble particles to provide visual enjoyment, and can effectively deliver the conditioning agent in the particles to the skin.

Quality factors of general human body cleaners include aroma, moisturizing power, foaming power, and rinsing property. Aroma and moisturizing power are the most important quality factors, and bubble power and rinsing water are basic quality factors. Here, the core quality factor is the most important element among the components of quality, and the basic quality factor means that the quality of power up to a certain level is more important than the core quality factor, but if it is above a certain level, its importance is lower than the core quality factor.

In recent years, as a whole body human cleanser, proper cleansing power and less irritation to the skin, as well as providing a moisturizing power and visual pleasure have been constantly required. As a result, 2 in 1 products have recently been introduced to provide such functions to a single product. However, the above products are separated over time to degrade aesthetic enjoyment, or the stability is poor when stored for a long time, so that the moisturizer or emollient is separated, causing the suspended insoluble particles to sink or comfort over time. There is a disadvantage that the case of floating.

Therefore, various stabilizers have been used to overcome the above disadvantages, and in particular, xanthan gum or carbopol have been used to float insoluble particles containing inorganic particles or conditioning agents for moisturizing for aesthetic enjoyment. However, the above components also have a problem in the stability of the product in formulations that impair the feeling of use or contain a large amount of anionic surfactant.

In addition, xanthan gum of the various thickeners that have been used to suspend insoluble particles in the prior art has the disadvantage that the appearance of the formulation is agglomerated overall, slippery in use, and the stability is also poor, compared to xanthan gum in the case of Carbopol The appearance and stability is good, but it feels pulling after use, it is cumbersome because it needs to be neutralized, and there is a disadvantage that one more process is required.

Accordingly, the present inventors have studied a human cleansing composition that can effectively deliver a conditioning agent to the skin while breaking insoluble particles when used on the skin and give aesthetic pleasure to the consumer, and as a result, water-soluble surfactants, insoluble particles containing the conditioning agent, and In the case of a human cleanser composition containing a hydroxy-containing crystalline particle floating agent, it has been found that the insoluble particles not only stably float but also exhibit excellent usability. In particular, the present invention solves the shortcomings of various thickeners that have been used to suspend insoluble particles by preparing whole body human cleansers containing insoluble particles using hydroxy-containing crystalline particles as a new insoluble particle floating agent. It has been found that the present invention has been completed.

Accordingly, it is an object of the present invention to provide a whole body human cleanser composition capable of stably suspending insoluble particles containing a conditioning agent.

In order to achieve the above object, the whole body human cleanser composition of the present invention comprises (a) a water-soluble surfactant, (b) an insoluble particle containing a conditioning agent, (c) a crystalline particle floating agent containing hydroxy, and (d ) It is characterized by containing water.

The alkyl and / or acyl chain length of the surfactant is C _6-22 , preferably C _12-18 , more preferably C _12-14 . In addition, the anionic surfactant is contained in an amount of 10 to 20% by weight, preferably 15 to 18% by weight based on the total weight of the composition.

Amphoteric surfactants used in the present invention are known to exhibit high surfactant and foaming power while being less irritant. Amphoteric surfactants usable in the present invention include coco ampocarboxypropionate, coco ampocarboxy propionic acid, coco ampoacetate, coco ampodiacetate (coco ampocarboxyglycinate), sodium lauro ampoacetate (sodium lauro ampoate) Carboxyglycinate) and the like. In addition, the said amphoteric surfactant is not specifically limited, It is used in the range which maintains transparency of an aqueous phase. Preferably, the content is 0.2 to 0.5% by weight based on the total weight of the composition.

The nonionic surfactant used in the present invention is not necessary but preferably contained. Specific examples include aliphatic alcohols, sorbitan, sorbitol esters, alkylate polyclicosides, amine oxides, alkanolamides, and the like. Of these, alkanolamides and alkylate polyglucosides are preferred. The nonionic surfactant content is not particularly limited and is contained in an amount of 0.5 to 10% by weight, preferably 0.75 to 7% by weight, and more preferably 1 to 4% by weight, based on the total weight of the composition. This is because if it exceeds 10% by weight, it is not effective in terms of intrinsic effect or price.

The whole body human cleansing composition of the present invention provides a conditioning agent to the skin by a method of stably suspending insoluble particles containing (b) the conditioning agent in an aqueous phase. The insoluble particles are substances that can be stably suspended without being dissolved in an aqueous phase, and contain oils, insoluble substances, or conditioning agents that soften the skin or hair, and include substances that can be broken by touching the skin or hair during washing. it means. Specifically, the material forming the particles is a material that is affinity for water, skin and hair, and generally include materials such as gelatin, gum, collagen, polypeptide or alginate, polyamide, etc. derived from plants or animals.

The insoluble particles contain a conditioning agent such as vitamin, and are prepared using coacervation, multicoating, microcapsules, and the like. The conditioning agent may be any material that can give a conditioning effect to the skin, such as antioxidants, vitamins, oils. The manufacturing method of the said insoluble particle is not specifically limited, It manufactures using a well-known method.
