Detailed Description Of The Invention
The transparent beauty treatment soap composition that the present invention relates to provides foaming abundancy, gentle, washes the performance that rear skinfeel is moistened, and has good transparency.Such performance by compositions but not in compositions a certain component provide.Such compositions comprises solvent, the content limited in the present invention, and the feature of any additional or optional component or restriction, or is made up of them or is substantially made up of them.
Particularly, such compositions, comprise soap base, amino acid surfactant, crystallization auxiliary and water, the interpolation of amino acid surfactant, the degreasing power of formula can be reduced preferably, increase the mildness of formula, improve the foaming properties of formula and use sensation, it is very important for having good foam to formula, obtaining moist not tight rear skinfeel of washing.Adding of crystallization auxiliary, very important effect is played to the transparency of formula, also provide good moisture retention to formula simultaneously.
The solvent of the transparent beauty treatment soap composition that the present invention relates to, and additional or that can optionally add component, using method and production technology are described in detail all hereinafter.
1 solvent
The solvent of transparent beauty treatment soap composition of the present invention comprises soap base, amino acid surfactant, crystallization auxiliary and aqueous carrier, and each in these components is all hereafter being described in detail.
a soap base
Transparent beauty treatment soap composition of the present invention comprises the soap base component being suitable for being applied on skin accounting for composition weight 5.0% to 51.2%.Described soap base component is made up of with the alkali accounting for composition weight 0.0%-11.2% the fatty acid be applied on skin that is suitable for accounting for composition weight 5.0%-40.0%.The consumption of described alkali is determined by the degree of neutralization of fatty acid.This part content relates generally to the detailed description to fatty acid, alkali and degree of neutralization.
a1 fatty acid
Transparent beauty treatment soap composition of the present invention comprises and accounts for composition weight 5.0% to 40.0%, preferred 10.0%-30.0%, further the fatty acid being suitable for being applied on skin of preferred 12.0%-20.0%.Described fatty acid is the compositions of fatty acid, this aliphatic acid composition can give foam, hardness, outward appearance, cleaning force and skinfeel needed for transparent beauty treatment soap composition of the present invention, most importantly, its content of fatty acid preferably accounting for composition weight 12.0%-20.0% is further significantly less than the content of fatty acid (being usually greater than 70%) of normal transparent soap routine, while ensure that good cleaning force, reduce the degreasing power of transparent soap, contribute to reducing transparent beauty treatment soap and wash the tight use sensation of rear drying.
The example being suitable for the fatty acid of transparent beauty treatment soap composition of the present invention includes but not limited to: sad, capric acid, lauric acid, myristic acid, Palmic acid, stearic acid, hexadecanoic acid, octadecanoid acid or its two or more mixture.
The application performance that different fatty acids provides mainly in zest, cleaning force, degreasing power, foaming properties (comprising the size of foam, the uniformity, elasticity, foam stability etc.), formula hardness, outward appearance, wash in rear skinfeel etc. and show diversity.As, 1. the foam that produces of fatty acid is more and more tiny along with the increase of fatty acid molecule amount, foam is also more and more stable simultaneously, but the difficulty that foam generates is also increasing, zest also weakens with the increase of fatty acid molecule amount simultaneously, and the foam produced as lauric acid is maximum, also the most easily disappear, zest is comparatively large, and the foam that octadecanoid acid produces is tiny and lasting, simultaneously gentleer; 2. the fatty acid of high molecular can provide higher hardness to formula; 3. fatty acid soaps has polymorphism, mainly there is the crystal formations such as α, β, δ, ω in its micro structure, and alpha-crystal form and δ crystal formation are unstable, easily change beta crystal or ω crystal formation into, therefore the mixture of soap body in fact mainly β, ω two kinds of crystal formations.The crystal formation affecting transparency then mainly beta crystal, its content more soap bodies transparency is higher.In soap, the ratio of beta crystal increases with hydrophobic group chain length and increases, be in the soap of 8 ~ 12 at hydrophobic group chain carbon atom quantity, beta-crystalline form content is less than 30% (mass percent), when carbon number is 13 ~ 15, beta crystal reaches 50% (mass percent), and when carbon number is 16 ~ 19, beta-crystalline form content can reach 60% (mass percent).Therefore, C in satisfied fatty acid
12~ C
18alkyl fatty acid soap easily reaches transparent, and carbochain is more long more transparent.It is relation between soap crystal phase structure and chemical composition that table 1 lists.
Relation between table 1 soap crystal phase structure and chemical composition
Consider transparency, foam, zest, degreasing power, formula hardness, wash the factors such as rear skinfeel, the fatty acid be preferred in transparent beauty treatment soap composition of the present invention is lauric acid, myristic acid, Palmic acid, stearic acid, at least one in hexadecanoic acid, octadecanoid acid, preferred lauric acid, myristic acid, stearic mixture.The preferred weight ratio of described fatty acid mixt is lauric acid: myristic acid: stearic acid=0 ~ 1: 1 ~ 3: 1 ~ 6, more preferably 0.5 ~ 1: 1 ~ 2.5: 2 ~ 5, most preferably be 1: 1 ~ 2: 2 ~ 4.The preferred 80%-100% of described lauric purity, further preferred 90%-100%, most preferably 95%-100%.The preferred 80%-100% of purity of described myristic acid, more preferably 90%-100%, most preferably 95%-100%.Stearic acid described in the present invention, it is the mixture of hexadecanoic acid and octadecanoid acid, preferred hexadecanoic acid: the mass ratio of octadecanoid acid is the mixture of 10 ~ 80: 90 ~ 20, be more preferably hexadecanoic acid: the mass ratio of octadecanoid acid is the mixture of 40 ~ 80: 60 ~ 20, most preferably is hexadecanoic acid: the mass ratio of octadecanoid acid is the mixture of 60 ~ 80: 40 ~ 20.Described stearic acid, can be commercially available prod, as commodity are called Edernor ST05M (purchased from section's Ninghua work).
