Description

Cleaning composition and method for stabilizing dimethylpolysiloxane

[Technical Field] The present invention relates to a detergent composition that has good foaming and can provide smoothness when finished, and a method for stabilizing dimethylpolysiloxane that can improve the stability of dimethylpolysiloxane.

In recent years, women's hair has become more susceptible to physical damage due to daily hair washing, styling, hair dryer, and the like, and chemical damage due to hair dyeing, bleaching, perm treatment, and the like, with an increasing awareness of cleanliness and fashion. Problems with damaged hair include a feeling of squeezing when shampooing is rinsed, deterioration of the smoothness of the hair when finished, and deterioration of combing.
In addition, anionic surfactants such as higher fatty acid salts, polyoxyethylene alkyl ether sulfates, alkyl ether phosphates, and amino acid surfactants are usually used as main components for washing, and these are combined with amphoteric surfactants and nonions. A surfactant and a cationic polymer are combined. However, such a conventional cleaning composition has a problem that, when used on the skin, the skin is not smooth and moist after washing.

For such problems, cationic polymers and silicone emulsions may be blended as finished components.
However, since silicone is hydrophobic, it has a problem in that it does not interact with a hydrophilic preparation and it is difficult to maintain stability over time.

For the stability of silicone over time, for example, an anionic surfactant, an amphoteric surfactant, a dimethyldiallylammonium salt / acrylamide copolymer, and ammonium sulfate are added to a hair cleansing composition containing highly polymerized dimethylpolysiloxane. In addition, by specifying the mass ratio of the anionic surfactant and the amphoteric surfactant, a hair cleaning composition having a dispersion stability of dimethylpolysiloxane and a high-temperature storage stability has been proposed ( Patent Document 1).

Further, a liquid detergent composition is proposed in which a silicone derivative and isoprenglycol or ethanol are dispersed at a specific content ratio in a high concentration aqueous anionic surfactant solution (Patent Document 2). reference).

In addition, by incorporating a specific polysaccharide derivative with silicones, a hair cosmetic is proposed in which silicones are stably dispersed, the feel during rinsing is smooth, and slipperiness can be imparted to hair after drying. (See Patent Document 3).

However, these prior art documents have been problematic in that the separation stability of silicones is not sufficient. Further, when silicones are blended, there is a problem that foaming deteriorates.

Therefore, the dimethylpolysiloxane has excellent separation stability, has good foaming, and can provide smoothness when finished, and the stability of dimethylpolysiloxane can improve the stability of dimethylpolysiloxane. At present, it is desired to provide a conversion method.

The component (A) is not particularly limited and may be appropriately selected depending on the intended purpose. Examples thereof include monoalkyl (C12-18) phosphate ester, dialkyl (C12-18) phosphate ester, trialkyl ( C12-18) phosphate ester, monoalkyl (C12-18) phosphate ester salt, dialkyl (C12-18) phosphate ester salt, trialkyl (C12-18) phosphate ester salt, monopolyoxyethylene alkyl (C12- 18) Ether phosphate ester, dipolyoxyethylene alkyl (C12-18) ether phosphate ester, tripolyoxyethylene alkyl (C12-18) ether phosphate ester, monopolyoxyethylene alkyl (C12-18) ether phosphate ester salt , Dipolyoxyethylene alkyl (C12 18) ether phosphate salt, such as tripolyphosphate polyoxyethylene alkyl (C12 ~ 18) ether phosphate salts. These may be used alone or in combination of two or more.
Among these, the component (A) is preferably polyoxyethylene alkyl (C12-18) ether phosphate ester or polyoxyethylene alkyl (C12-18) ether phosphate salt.

Commercially available products can be used as the polyoxyethylene alkyl (C12-18) ether phosphate ester and the polyoxyethylene alkyl (C12-18) ether phosphate ester salt. Specific examples thereof include di-POE (10 ) Sodium lauryl ether phosphate (NIKKOL DLP-10, HLB 17.0), diPOE (8) sodium oleyl ether phosphate (NIKKOL DOP-8NV, HLB 12.5), diPOE (4) alkyl (C12-15) ) Ether phosphoric acid (NIKKOL DDP-4, HLB 9.0), di-POE (6) alkyl (C12-15) Ether phosphoric acid (NIKKOL DDP-6, HLB 9.0), di-POE (8) alkyl (C12-15) ) Ether phosphoric acid (NIKKOL DDP-8, HLB) 1.5), di-POE (10) alkyl (C12-15) ether phosphate (NIKKOL DDP-10, HLB 13.5), tri-POE (4) lauryl ether phosphate (NIKKOL TLP-4, HLB 13.0), Tri-POE (5) cetyl ether phosphate (NIKKOL TCP-5, HLB 10.0), tri-POE (6) alkyl (C12-15) ether phosphate (NIKKOL TDP-6, HLB 8.0), tri-POE (8) Alkyl (C12-15) ether phosphate (NIKKOL TDP-8, HLB11.5), tri-POE (10) alkyl (C12-15) ether phosphate (NIKKOL TDP-10, HLB14.0) (all Nikko Chemicals shares) Company-made).

The HLB of the component (A) is not particularly limited as long as it is 8 to 17, and can be appropriately selected according to the purpose. However, 10 to 14 is that the three-dimensional structure of the triphosphate is bulky. Therefore, it is preferable in that it is more effective in the separation stability of the component (B). If the HLB is less than 8, the separation stability and foaming of the component (B) may be reduced, and if it exceeds 17, the separation stability of the component (B) may be reduced.

The HLB value by the emulsification method described in “Handbook -Cosmetics / Formulation Raw Materials—Revised Edition”, Nikko Chemicals Co., Ltd., published February 1, 1977, page 854-855. It conforms to the actual measurement. As a specific method for obtaining the HLB value of the component (A), the component (A) is combined with sorbitan monostearate (NIKKOL SS-10, HLB 4.7) as a standard substance for an emulsifier. The total amount of seed emulsifier is constant, and only the ratio is changed to emulsify liquid paraffin (HLB10.1) to be emulsified, and after standing overnight, it is stable in terms of creaming amount, white turbidity, lower layer water separation, etc. However, the ratio of the optimal emulsifier is calculated | required and the HLB value x of the said (A) component is computed by following formula (1).
y = (x × used amount (mass%) + z × used amount (mass%)) / 100 Formula (1)
Here, in Formula (1), “x” represents the HLB value of the component (A), “y” represents the HLB value of liquid paraffin, and “z” represents sorbitan monostearate (NIKKOL SS). This shows the HLB value of -10).

Next, the intrinsic viscosity [η] is obtained by substituting it into the Huggins relational expression shown in the following formula (3). As the Huggins constant, the one described in Nakamuta, Nikka, 77, 588, [1956] is used. Next, [η] is represented by A. Substituting it into the Kololov equation, the molecular weight M is determined. Lastly, M is an A.I. J. et al. Substituting into the Barry equation, the kinematic viscosity η of dimethylpolysiloxane can be determined.
ηsp = (η / η0) −1 Formula (2)
ηsp = [η] + K ′ [η] ² Formula (3)
[Η] = 0.215 × 10 ⁻⁴ M ^0.65 Formula (4)
