Abstract
The present invention provide a soap composition, which undergoes swelling and melting down to less extent in use and exhibits good foaming ability and is made by blending cheap material. As the primary material making the soap, 60-92wt.% fatty acid soap containing a palm kernel fatty acid salt and a palm stearin fatty acid salt at a weight ratio of (7:3) to (3:7) is blended with 3-20wt.% 8-22C higher fatty acid and 5-20wt.% water is adopted.
Description
The present invention relates to a kind of soap composition, owing to soak softening hardly or distortion, whipability is good, and available cheap material makes in use for this soap composition.
During the usual way of producing soap comprises and lipid acid, be by coming hydrolysed fat with aqueous sodium hydroxide solution, for example tallow, coconut fat or plam oil and make; Or the direct above-mentioned fat of saponification, obtain the soap base composition, then add spices, pigment etc. therein.
Usually, the fat that is used as raw material in soap production comprises 60-80% (weight) tallow and 20-40% (weight) Oleum Cocois.The composition of this feedstock fat greatly influences performance, the sense of touch and the cost when using of soap products.A kind of when using in molten chamber in order to produce, the almost indeformable soap owing to soak for example, requires to improve the ratio of the tallow that contains a large amount of relatively lipid acid with long carbochain.Yet increase contains the ratio of the tallow of the lipid acid that has long carbochain in a large number, will reduce the solvability of soap in water, also can reduce whipability, thereby cause the minimizing of lather volume.When the ratio that contains the Oleum Cocois of a large amount of relatively short chain fatty acids when increase solved these problems, the solvability of soap in water was improved, and whipability is improved.Yet in this case, the soap meeting is gross distortion owing to soak.And Oleum Cocois is more expensive than tallow, and the result increases product cost.
Therefore, the someone propose a kind of with low-cost, excessively do not improve the method that the Oleum Cocois ratio improves the soap whipability, in order that eliminate because the distortion that immersion causes.During this method is included in and in the step of lipid acid, use the excess fatty acids that surpasses sodium hydroxide, make soap contain free fatty acids.Yet, when soap contains the huge amount free fatty acids, improved hydrophobicity on the soap surface, consequently, under than lesser temps (for example about 10 ℃ or be lower than 10 ℃), the solvability of soap in water reduces especially, and the whipability of soap also greatly reduces at low temperatures.Therefore, in order to improve whipability, the lipid acid amount that is added in the soap is limited.
Though in order to improve whipability, the soap that is made by the mixture of tallow and Oleum Cocois contains free fatty acids, but still produces a problem, promptly under the immersion situation, good whipability and strong anti-deformability are difficult to realize simultaneously under low-cost situation.
In order to address this problem, JP-A-6-57298 has proposed a kind of solid soap composition, and this solid soap composition is to mix (term used herein " JP-A " means " not examining disclosed Japanese patent application ") for preparing with the natural acid soap that contains palm oil fatty acid salt and coco-nut oil fatty acid salt by higher fatty acid and water.Plam oil and Oleum Cocois are as feedstock fat in this solid soap composition.That is, the tallow part in raw material commonly used is substituted by plam oil.Yet wherein said solid soap composition has shortcoming, that is, the expensive plam oil that is used as raw material improves product cost, and another shortcoming is that softening and distortion can not fully suppress, because contain a large amount of oleic acid as the plam oil of raw material.
In order to solve the problems referred to above that face in the prior art, the object of the invention is to provide a kind of whipability good, the distortion and can be with the soap of low cost production hardly owing to soak.
The inventor finds that above-mentioned purpose can be made feedstock fat by the palm-kernel oil and the palm stearines of specified proportion by adopting, and prepares fatty acid soaps and reaches, thereby finish the present invention.
Therefore, the invention provides a kind of soap base composition and soap composition.This soap base composition comprises that its weight ratio is 7: 3-3: 7 by the soap of palm kernel oil-derivation with by palm stearines derived fatty acid salt; Soap composition comprises that it is 7 that 60-92% (weight) contains weight ratio: 3-3: 7 by the soap of palm kernel oil-derivation with by the fatty acid soaps of palm stearines derived fatty acid salt, 3-20% (weight) has the higher fatty acid and 5-20% (weight) water of 8-22 carbon atom.
Now, the present invention is described in detail.
The fatty acid soaps that is used for soap composition of the present invention comprises and mainly containing by the soap of palm kernel oil-derivation with by the mixture of palm stearines derived fatty acid salt.
By obtaining with alkali metal hydroxide or alkaline earth metal hydroxides saponification palm-kernel oil, this palm-kernel oil obtains by the compacting Fruit of Fortune Windmillpalm or with the solvent extraction Fruit of Fortune Windmillpalm by the soap of palm kernel oil-derivation.In addition, can be by also obtaining soap by the lipid acid of palm kernel oil-derivation with the neutralization of alkali metal hydroxide or alkaline earth metal hydroxides.Palm-kernel oil contains can make soap have the lauric acid of good whipability in a large number.Therefore, make feedstock fat, can have the soap of good whipability with low cost production by adopting palm-kernel oil.
With regard to regard to the fatty acid composition of the lipid acid of palm kernel oil-derivation, someone proposes from the whipability viewpoint, should use to comprise 50-60% (weight) lauric acid, 10-20% (weight) tetradecanoic acid and oleic those fatty acid compositions of 8-15% (weight).
Obtain with following method by palm stearines derived fatty acid salt, to obtain the plam oil fractionation by compacting palm pericarp and become palm stearines (being the solid fat form under 20-25 ℃) and palm olein (under 20-25 ℃, being the liquid aliphatic form), then with alkali metal hydroxide or alkaline earth metal hydroxides saponification palm stearines.In addition, also can be by obtaining by the palm stearines derived fatty acid with alkali metal hydroxide or alkaline earth metal hydroxides neutralization.Palm stearines is to contain the residuum that obtains behind the oleic palm olein that can be used for foodstuffs industry of a large amount of costlinesses at fractionation plam oil and recovery.Therefore, compare with plam oil, palm stearines can cheaply obtain, and contains a small amount of oleic acid.Therefore, adopt palm stearines to make feedstock fat, can cheap production can avoid causing soap softening and distortion owing to soaking.
With regard to regard to the fatty acid composition of palm stearines derived fatty acid salt, someone proposes from avoiding causing owing to immersion the viewpoint of distortion, should use to comprise 50-70% (weight) palmitinic acid 3-8% (weight) stearic acid and oleic those fatty acid compositions of 25-35% (weight).
In the present invention, be 7 by the soap of palm kernel oil-derivation with weight ratio: 3-3: 7, preferred 6: 4-4: 6 by palm stearines derived fatty acid salt.Though, can improve whipability by the ratio that increases by the soap of palm kernel oil-derivation, surpass at 7: 3 o'clock by the ratio of the soap of palm kernel oil-derivation, because immersion can make the significantly softening and distortion of soap composition.On the other hand, when surpassing 3: 7 by the ratio of palm stearines derived fatty acid salt, the solvability of soap composition in water obviously reduces and lathering property descends.
Soap composition of the present invention also comprises the higher fatty acid with 8-22 carbon atom, so that produce the butteriness foam.The carbonatoms of these higher fatty acid should be controlled at 8-22.This is because have the higher fatty acid meeting intense stimulus skin that is less than 8 carbon atoms, and has disagreeable smell.On the other hand, the higher fatty acid that has more than 22 carbon atoms has very high fusing point, makes the decreased solubility of soap in cold water or warm water.
Can adopt straight or branched, saturated or unsaturated fatty acids as these higher fatty acid.Example wherein comprises mono fatty acid, for example lauric acid, tetradecanoic acid, palmitinic acid and stearic acid, natural acid, for example by the lipid acid of palm kernel oil-derivation, by palm stearines derived fatty acid, coco-nut oil fatty acid and tallow fatty acids.Perhaps one of these lipid acid or their mixture all can use.Specifically, from the viewpoint of whipability, the preferred lipid acid that uses by palm kernel oil-derivation.
These higher fatty acid or can join in the above-mentioned soap base composition perhaps can be present in the soap base composition with unneutralized lipid acid form by the degree of neutralization of regulating raw fatty acid.
Soap composition of the present invention contains 3-20% (weight), the higher fatty acid of preferred 5-15% (weight).When the content of higher fatty acid was lower than 3% (weight), the whipability of soap composition can not substantially improve.On the other hand, when its content surpassed 20% (weight), weakening of soap composition hardness can make its moldability reduce.
In addition, soap composition of the present invention contains water.Water-content is 5-20% (weight), preferred 8-15% (weight).When water-content is less than 5% (weight), when soap composition uses with cold water, can present undesirable coarse structure.In these cases, the solvability of soap composition and whipability also reduce.On the other hand, when water-content surpassed 20% (weight), weakening of soap composition hardness can make its moldability reduce.
