Description

High-functional silicone emulsion composition and manufacturing method {PREMIUM SILICONE EMULSION COMPOSITION AND METHOD FOR PREPARING THE SAME}

The present invention relates to a high functional silicone emulsion composition and a method for producing the same, and more particularly, to include polydimethylsiloxane and amino modified siloxane as silicone oil components, having an appropriate viscosity, excellent conditioning effect, cleaning effect and hair protection effect. The present invention relates to a high-functional silicone emulsion composition and a method for producing the same, which can be particularly suitably used for hair care products such as shampoo, rinse, hair conditioner, hair treatment, and the like.

As modern lifestyles become more common, damage to the surface of hair is aggravated by external sources of irritation and chemical penetration, such as excessive combing, drying and frequent cleaning. Accordingly, there is an increasing demand for hair care products (eg, shampoo, rinse, hair conditioner, hair treatment, etc.) that can prevent hair damage and protect hair, and have excellent gloss and combing.

Recently, products that combine two functions have been attracting attention in order to save time and eliminate the inconvenience of separately using shampoo and rinse. Emulsions using silicone as a prominent means are particularly attracting attention. Silicone has high molecular weight and small change in viscosity due to temperature change, and excellent permeability to oxygen or carbon dioxide, and does not interfere with skin breathing, and it is optimal for hair cleaner and cosmetics because it gives continuous gloss and shine when used in hair. It can be called the material of. Emulsions containing silicones have been suggested from low to high viscosities, but those with high viscosities are excellent in residual and combing.

In general, a method of preparing a silicone emulsion can be divided into two types, that is, a mechanical emulsion method and an emulsion polymerization method. Since the mechanical emulsification method requires physical work by homogenizing the organopolysiloxane using a grinder, an emulsion can be formed by using an organopolysiloxane having a limited viscosity. On the other hand, the emulsion polymerization method is to prepare an emulsion of high viscosity polymer by reacting cyclic siloxane in the presence of water, catalyst and surfactant. The mechanical emulsification method is disclosed in US Patent No. 5,633,303, Korean Laid-Open Patent No. 2001-0038746, Korean Patent No. 121132, and the like, and the emulsion polymerization method is disclosed in US Patent No. 5,852,110.

However, conventional silicone emulsions still need improvement in the effects of cleaning, conditioning and combing.

U.S. Patent 5,633,303 Korean Laid-Open Patent No. 2001-0038746 Korean Patent No. 121132 U.S. Patent 5,852,110

The amount of water added during the preparation of the emulsion can be appropriately adjusted according to the required solid content, it is preferable to add 10 to 50% by weight based on the total weight of the emulsion. If the amount of water is too small or too large than the above range, the emulsion stability, viscosity and the like may worsen.

(B) polydimethylsiloxane

The polydimethylsiloxane (hereinafter also referred to as "component B") is preferably used as a silicone oil in an amount of 10 to 70% by weight, more preferably 30 to 70% by weight, based on the total weight of the emulsion. If the content is less than 10% by weight, it may not be able to exhibit conditioning effects such as combing and residual properties of silicone oil, and if it exceeds 70% by weight, it may be difficult to pass the emulsifier by increasing the silicon content. May lead to an increase in content.

Moreover, the weight average molecular weight becomes like this. Preferably it is 60,000-500,000, More preferably, it is 100,000-500,000. If the viscosity or weight average molecular weight of the polydimethylsiloxane is too low than the above level there may be a problem in not properly exhibiting the conditioning effect, on the contrary, if the viscosity or weight average molecular weight is too high, the hair may feel heavy.

According to a preferred embodiment of the present invention, when using a mixture of low viscosity polydimethyl siloxane (viscosity: 100 ~ 100,000 cP) and high viscosity polydimethylsiloxane (viscosity: 500,000 ~ 20,000,000 cP) as a polydimethyl siloxane, characteristics of the high viscosity polymer This is more prominent, and as a result, the feeling of combing, residual property, and the like is excellent, and when applied to products such as hair rinse, hair conditioner, etc., a film can be formed on the hair to form smooth and shiny hair. When low viscosity polydimethyl siloxane and high viscosity polydimethylsiloxane are used together, the ratio of low viscosity polydimethyl siloxane to high viscosity polydimethylsiloxane is preferably in a weight ratio of 0.2: 1 to 5: 1, more preferably 0.5: 1 to 2: 1.

(C) amino modified siloxanes

Amino-modified siloxanes (also referred to as "(poly) components") are silicone oils used in a variety of hair care products, which can coat the hair to form smooth, shiny hair, and also negative charge This is because the band helps to maintain the softness for a long time by attaching a positively charged amino group to the hair. In the emulsion composition of the present invention, the amino modified siloxane is preferably used in an amount of 5 to 50% by weight, more preferably 10 to 40% by weight based on the total weight of the emulsion. If the content is less than 5% by weight there may be a problem that the conditioning effect is not properly exhibited, if the content exceeds 50% by weight may have a yellowing problem when applied to hair care products or fibers.

The viscosity range of amino modified siloxane is 100-80,000 cP, Preferably it is 100-5,000 cP, More preferably, it is 500-2,500 cP. The weight average molecular weight is preferably 100 to 120,000, more preferably 10,000 to 120,000. If the viscosity or weight average molecular weight of the amino-modified siloxane is too lower than the above-mentioned level, there may be a problem that the conditioning effect is not properly exhibited. On the contrary, if the viscosity or weight average molecular weight is too high, yellowing problems may occur when applied to hair care products or fibers. There may be.

The amino group content in the amino modified siloxane is preferably 0.01 to 1.5% by weight, more preferably 0.05 to 0.97% by weight based on 100% by weight of the amino modified siloxane. If the amino group content is less than the above range may reduce the effect of imparting softness to the hair, on the contrary, if it exceeds the above range, yellowing may occur in the emulsion.

The silicone emulsion composition of the present invention contains the polydimethylsiloxane and amino modified siloxane described above together as silicone oil components. The use ratio of polydimethylsiloxane to amino modified siloxane is preferably in a weight ratio of 10: 1 to 0.2: 1, more preferably 7: 1 to 0.5: 1, even more preferably 5: 1 to 1: 1.

The total content of polydimethylsiloxane and amino modified siloxane in the silicone emulsion composition of the present invention is preferably 30 to 80% by weight, more preferably 50 to 70% by weight based on the total weight of the composition. If the sum of these silicone oils is too lower than the above-mentioned level, there may be a problem that the conditioning effect is not properly exhibited, and if too high, there may be a yellowing problem when applied to hair care products or fibers.

(D) nonionic surfactants

Nonionic surfactants (hereinafter also referred to as "components") include, for example, polyoxyethylene alkyl ethers, polyoxyethylene allylalkyl ethers, polyoxyalkylene alkylphenol ethers, polyoxyalkylene aryl esters, polyoxyalkyls Ethylene sorbitan alkyl esters, sodium lauryl ether sulfate, stearyl trimethyl ammonium chloride and mixtures thereof may be used, but is not necessarily limited thereto.

The nonionic surfactant is preferably used in an amount of 1 to 30% by weight, more preferably 5 to 20% by weight, based on the total weight of the emulsion. If the content is less than 1% by weight, the emulsification may not be performed properly. If the content is more than 30% by weight, it may inhibit the conditioning effect (gloss, coatability, etc.) of the final emulsion.

Nonionic surfactants are used in consideration of the hydrophilic lipophilic balance (HLB) value. If the HLB value of the nonionic surfactant is adjusted to 10 to 13, the emulsion stability of the emulsion can be improved. At this time, it is preferable to adjust the final HLB value to 10-13 by mixing 2 types of components from which HLB value differs. When a component having a small HLB value (HLB 5-12) and a component having a large HLB value (HLB 12-20) are used together, stability at room temperature and high temperature is further excellent. The use ratio of the two components can be appropriately selected depending on the specific components and the desired final HLB value.

(E) Neutralizer

The neutralizing agent (hereinafter also referred to as "(e) component") is selected from the group consisting of acetic acid, lactic acid, citric acid, formic acid, nitric acid, glycolic acid, phosphoric acid, hypophosphorous acid, and mixtures thereof, for example. It may be used, but is not necessarily limited thereto. The primary purpose of using this component is to neutralize, and the secondary purpose is to chloride amino modified siloxanes. The amino groups in the siloxane oil portion of micelles may make the emulsion appear subtle, which can be solved by adding a neutralizing agent to form salts with the amino groups (cations). The resulting ammonium salt is well soluble in water and has good surface activity.

The neutralizing agent is preferably used in an amount of 0.001 to 10% by weight, more preferably 0.1 to 1% by weight based on the total weight of the emulsion. If the content is too small, the pH of the emulsion may be too low to reach the target specification, so that the addition of a pH adjuster may be cumbersome. If the content is too high, the pH of the emulsion may be too high, which may cause problems in emulsion stability.

(F) preservative

In addition to the above components, preservatives (hereinafter also referred to as "bar components") may be further mixed in the preparation of the emulsion. By applying a preservative, it is possible to secure the storage stability of the product by inhibiting the microbial habitat that may occur during the product production process and long-term storage. The preferred amount of preservative is 0.01 to 10% by weight based on the total weight of the emulsion.

As a preservative, preservatives commonly used in the preparation of silicone emulsions may be used, and in one embodiment, cosmetic preservatives such as KATHON CG and Neolone 950 whose main component is 2-methyl-4-isothiazolin-3-one (MIT) (ROHM AND HAAS Co., Ltd.) etc. can be used.

Combing

First, a hair bundle of 12 g in weight and 30 cm in length was prepared. In order to obtain more objective test results, five test personnel were selected, and each of them performed the tests on three hair bundles in the following order. One hair bundle was washed in tap water at a constant temperature for 1 minute, and shampooed for 1 minute with 3 ml of a silicone emulsion prepared according to the Examples and Comparative Examples. Hold for 1 minute with foam, then wash again for 1 minute and wash by hand. Grab a bundle of hair and comb it three times in a row without combing. According to this process, three hair bundles were tested for each silicone emulsion to obtain an average time. Analyzing the test values measured for the five test personnel are shown in Table 3 below to evaluate the ease of combing in wet conditions.
