The difference between butter and castor oil when making handmade soap

Castor oil contains ricinic acid is an unsaturated fatty acid, easy to redox reaction with the oxygen in the air, add early if the reaction is easy to darken its color, affecting the made of translucent craft soap beauty. Castor oil for a long time heating easy to deepen the color, thus affecting the transparency of the product.

One, the handmade soap tallow and castor oil difference:

1, the basic parameters are different: the melting point of tallow than the melting point of castor oil is a little higher. Butter melting point of 40 ℃ -46 ℃, because its melting point is higher than the body temperature, not easy to be digested. Although it is not suitable for direct consumption, but it can make pastry shortening, so in the production of Western-style pastry, in European countries, commonly used as a shortening agent.

2, the nature of the oil is different: the production of handmade soap, tallow is an animal fat, while castor oil is a vegetable fat.

3, the wash effect is different: castor oil than tallow wash effect is good, so castor oil is more suitable for making handmade soap.

Two, butter

1, the basic parameters: the word butter has two meanings, one refers to cow dairy products, and the other refers to the fat from the cow's adipose tissue extracted from the oil. The two meanings are easily confused. The first meaning: butter, the English name is butter or butter fat. the second meaning: from the cow's adipose tissue extracted from the fat.

2, nature: in industrial production, the factory uses meat food processing enterprises of cattle fat tissue as raw materials, the use of wet process, by degumming, deacidification and other more than two dozen processed into butter.

3, wash effect: but the use of handmade soap made of tallow is easy to cause blockage of the pores, the skin is very unfavorable.

Three, castor oil

1, the basic parameters: castor oil is a triglyceride of fatty acids, castor oil is found in the seeds of castor, the content of which is 35% to 57%, with the extraction or solvent extraction method to obtain castor oil. Castor oil fat acid containing 90% ricinoleic acid, hydroxyl value of 163mgKOH/g, hydroxyl content of 4.94%, according to hydroxyl molecular weight of 929.26, according to hydroxyl deduction, castor oil contains 70% of the trifunctionality and 30% of the difunctionality of the hydroxyl group with an average functional degree of 2.7.

2, properties: easily dissolved in ethanol, difficult to dissolve in petroleum ether. The existence of this characteristic is easier to distinguish castor oil from other fats and oils. Viscosity is much higher than the general grease, viscosity index of 84, the coefficient of friction is very low. Castor oil in the air almost does not occur oxidation rancidity, storage stability is good, is a typical non-drying liquid oil.

3, the effect of washing: in the common household soap recipes can also see its figure, a strong foaming persistence can help coconut oil fluffy bubbles more durable, its foaming power is very good, but also can be rubbed out of the cream-type bubbles, and it has a kind of "slippery" effect, the soap can easily be able to slide open in the It has a "slippery" effect where the soap easily slides on the body, making the shower feel like the whole body is being moisturized by the lotion.
