Description

Multi-layer cleaning composition

The present invention relates to a multilayer cleaning composition.

Recently, a skin cleansing sheet in which a liquid skin cleansing agent is impregnated in a non-woven fabric and a skin cleansing agent that is impregnated in cotton etc. during use have been developed. Because it does not need to be rinsed after use, it can be used in any Place or time to remove cosmetics. There are two types of cleansing sheets/compositions: one contains surfactants as a cleansing base, which uses surfactants to remove cosmetics after emulsification (see PTL1), and the other It contains oil as a cleansing base to remove the oil-based type of cosmetics by dissolving in oil (see PTL2).

The surfactant-based type contains very little oil, and it provides a refreshing sensation during wiping, but it is difficult to remove waterproof eyelashes that contain stubborn components that firmly adhere to the skin (such as polymeric silicone and oily film formers) paste. The oil-based type has excellent cleansing power for cosmetics such as waterproof mascara, but it produces a greasy feel during wiping and remains sticky on the skin just after use (wiping).

Recently, among oil-based types, skin cleansers for wiping with reduced greasiness during wiping have been proposed. For example, a two-layer composition composed of a water layer and an oil layer has been proposed, which is shaken and impregnated in a wiping pad during use (see PTL3) and a type of emulsification that disperses a low-viscosity oil through emulsification Skin cleansing composition (See PTL4).

The present invention relates to the following items [1] and [2].

[1] A multilayer cleaning composition comprising the following components (A) to (E). (A) 0.003 to 0.3% by mass of a polymer containing monomers selected from (a1), (a2) and (a3):

(a1) A monomer selected from acrylic acid and methacrylic acid,

(a2) A monomer selected from alkyl acrylate and alkyl methacrylate, and

(a3) A monomer selected from polyoxyethylene alkyl ester of acrylic acid and polyoxyethylene alkyl ester of methacrylic acid,

(B) 5 to 40% oil by mass,

(C) 0.01 to 1.5% by mass of nonionic surfactant,

(D) 0.005 to 0.9% by mass of one or more selected from (d1) water-soluble salts and (d2) acids, and

(E) Water.

[2] A method of manufacturing the multilayer cleaning composition as described in [1], which comprises the following steps 1 to 3:

(Step 1) Mix component (A), component (B) and component (E) to obtain mixture 1,

(Step 2) Add component (C) to mixture 1 to obtain mixture 2, and

(Step 3) Add component (D) to mixture 2.

Even if the double-layer composition described in PTL3 becomes a uniform emulsion by shaking, when it is impregnated in cotton, it will essentially separate into a water layer and an oil layer. A large amount of oil is in direct contact with the skin, so the user will be in the process of wiping. It feels greasy. Regardless of whether it is mixed by shaking or not, the composition will quickly return to the double-layer state after standing for a while. It forces the user to shake the composition frequently, which is quite troublesome.

Regarding the skin cleansing composition described in PTL4, although it is a cleansing composition that imparts a refreshing feeling during use and produces high cleansing power for stubborn cosmetics such as waterproof mascara, it has considerable properties because it is a polymer-based emulsion. High viscosity (1,000mPa·s or more at 30°C). Therefore, it requires a whole day or a specific physical force to impregnate the composition in cotton, which is not suitable for wiping.

The inventors tried to develop a cleansing composition that has the best physical properties for impregnation in cotton, produces high cleaning power for cosmetics, and does not produce greasy feeling during wiping and sticky feeling immediately after use. . As a result, the inventors found that specific polymers, oils, nonionic surfactants, water in specific proportions, and in addition to water-soluble salts or acids in combination produce multilayer cleaning that can be easily impregnated in wipe materials such as cotton or non-woven The composition does not make the skin feel greasy during wiping and sticky just after use, and can remove stubborn cosmetics such as waterproof mascara, thereby completing the present invention.

Although the multilayer cleaning composition of the present invention contains a large amount of oil in the polymer-based emulsion, it can be quickly impregnated in a wiping material such as cotton. In addition, the multilayer cleaning composition is uniformly mixed and impregnated in the wiping material for use, such as by shaking, and then it can remove stubborn cosmetics such as waterproof mascara. In addition, the composition does not make the skin feel greasy during wiping and sticky just after use, and the user can The skin feels refreshed after use. Furthermore, once the composition is uniformly mixed, the composition can be maintained as a uniform emulsion when the user uses the multilayer cleaning composition of the present invention, and the user does not need to shake during the replacement of the wiping material.

In the multilayer cleaning composition of the present invention, the oil agent rises to the upper layer and maintains the emulsion state (emulsion layer such as O/W) and the water phase drops to the lower layer (water layer). It is the so-called emulsifiable concentrate separation, in which the composition is separated into at least two layers of the emulsion layer and the water layer. However, when the composition is mixed, the oil droplets (emulsified particles) can be easily and uniformly redispersed. When the user uses the multilayer cleaning composition of the present invention, it can be in a uniform emulsion state with low viscosity.

In the conventional multilayer cleaning composition that separates into an oil layer and a water layer in a static state, when mixed, the oil phase and the water phase are dispersed to form an emulsion. However, since the composition needs to cause phase separation, the strength of the surface film of the oil droplets is weak, and the emulsion state is easy to collapse and separate into an oil layer and a water layer. Therefore, when the composition is immersed in cotton, the composition is almost immediately separated into an oil layer and a water layer, where a large amount of oil agent may contact the skin and the user will feel a strong greasy feeling during wiping.

In contrast, in the present invention, when mixing, the oil droplets previously present in the emulsion layer can be uniformly dispersed in the entire composition. The strength of the surface film of the oil droplets is strong enough not to be destroyed in the stage of immersion in cotton, but the oil droplets will be destroyed by the physical force caused by wiping, and an appropriate amount of oil is released to produce high cleaning power. Therefore, when the cotton impregnated with the composition comes into contact with the skin, the oil will not be released from the oil droplets to the skin and the user feels refreshed, and no excessive oil will be released from the oil droplets during wiping. It also suppresses the greasy feeling and the user can get a refreshing feeling on the skin after use.

The polymer of component (A) used in the present invention contains one or more monomers selected from the following (a1), (a2) and (a3):

(a1) A monomer selected from acrylic acid and methacrylic acid,

(a2) A monomer selected from alkyl acrylate and alkyl methacrylate, and

(a3) A monomer selected from polyoxyethylene alkyl ester of acrylic acid and polyoxyethylene alkyl ester of methacrylic acid.

The polymer of component (A) used in the present invention is adsorbed on the oil/water interface and forms an adsorption layer that prevents the integration of oil droplets. Then the oil droplets are stabilized and the oil agent is dispersed in the water layer. Unlike micro-O/W emulsification using low-molecular-weight surfactants such as polyoxyethylene hydrogenated castor oil as the main emulsifier, the polymer of component (A) roughly (unevenly) emulsifies the oil. The oil can then be easily released from the oil droplets by the physical force during wiping. The released oil dissolves cosmetics, and the composition of the present invention can produce high cleaning power.

In addition, it is presumed that component (A) is inhibited from being distributed in the composition and will not be affected by the interaction with component (C) (nonionic surfactant) and component (D) (water-soluble salt or acid). The interaction greatly reduces the stabilizing effect of oil droplets, so it helps to suppress the greasy feeling during wiping.

When manufacturing the multilayer cleaning composition of the present invention, if the component (A) produces a thickening effect through neutralization, it is better to add the component after dispersing the component (A) in the component (E) (water) (K) (Alkaline neutralizer). In the present invention, the term alkaline neutralizer represents a substance that can accept protons from another substance (ie, a proton acceptor). After the component (A) is dispersed in the component (E), the component (K) is added to thicken the hydrogel by the component (A).

(Production method)

The multilayer cleaning composition of the present invention can be manufactured by mixing the components in a routine method. When the composition contains a solid material at room temperature, the solid material can be preheated to melt or dissolve in another component, and then all the components can be uniformly mixed for manufacture.

When component (A) (polymer), component (B) (oil agent), and component (E) (water) are mixed, component (A) is adsorbed on the oil-water interface and forms an adsorption layer, It prevents the oil droplets from integrating. Then the oil droplets stabilized. However, the emulsified composition with component (A) is quite easy to increase the viscosity, and the composition is usually difficult to impregnate in a wiping material such as cotton. However, the addition of component (D) ((d1) water-soluble salt or (d2) acid) can interfere with the formation of the hydrated gel and subsequently reduce the viscosity, but it will cause polymer aggregation and the oil agent will dissolve out from the oil droplets. To solve this problem, in the present invention, component (C) (nonionic surfactant) is added to the emulsion that has been pre-emulsified with component (A) before component (D) is added. Due to this, the polymer can maintain the emulsion state and inhibit polymer aggregation after the component (D) is added. The composition can release oil during wiping and can produce high cleaning power of cosmetics.

Regarding the polymer of the component (A) that produces a thickening effect through neutralization, the component (A) contains at least a carboxylic acid such as acrylic acid or methacrylic acid. These polymers are neutralized with the component (K) (alkaline neutralizer) in the mixture with the component (E) (water) to form a hydrated gel, thereby producing a thickening effect. During the thickening process, when the component (B) (oil agent) is present, the oil agent is trapped in the hydrated gel, thereby causing the oil agent to be roughly emulsified. However, the emulsified state caused by the component (A) can increase the viscosity of the composition, which will reduce the impregnation in the wiping material such as cotton. Therefore, as described in the above manufacturing method, by adding the component (C) (nonionic surfactant) to the emulsion pre-emulsified with the component (A) before adding the component (D), the polymerization can be maintained The substance roughly emulsifies the state of the oil and can inhibit the aggregation of the polymer after adding component (D). During the wiping, the composition releases the oil to produce the high cleansing power of the cosmetic.

Regarding the specific manufacturing method, the component (A) (polymer), component (B) (oil agent), component (E) (water) and optional component (K) (alkaline neutralizer) And other optional components as appropriate are mixed (and neutralized) to obtain Mixture 1. Next, component (C) (nonionic surfactant) and optionally surfactants other than component (C) are added to mixture 1 to obtain mixture 2. Mixing mixture 2 and component (C) can inhibit the accumulation of oil droplets. Subsequently, component (D) (component (d1) (water-soluble salt) or component (d2) (acid)) is added to the mixture 2 to obtain the composition of the present invention. The resulting composition can achieve low viscosity while maintaining oil droplets, and therefore it provides excellent impregnation in wiping materials such as cotton and even achieves excellent cleaning effect and usability.

The manufacturing method of the multilayer cleaning composition more specifically includes

(Step 1) Mix component (A), component (B) and component (E), and optionally component (K) alkaline neutralizer, and other optional components as appropriate to obtain Mixture 1.

(Step 2) Add component (C) to mixture 1, surfactants other than component (C) as the case may be, to obtain mixture 2, and
