![]() ![]() Good Housekeeping says it can be used mixed with vinegar to attract and drown fruit flies. Reader's Digest notes its use as an ant killer, weed killer, to help spread water-borne fertilizer, and to wash human hair. Automatic dishwashing detergents' surfactants generally have less foam to avoid disrupting the machine. The cleaning is less reliant on the detergent's surfactants but more reliant on machine's hot water as well as the detergent's builders, bleach, and enzymes. It is generally chosen through convenience, sanitation, or personal preference. Automatic dishwashingĪutomatic dishwashing involves the use of a dishwashing machine or other apparatus. Those with "sensitive skin" are advised amongst other things to persuade someone else to do the washing up. However, most people also rinse the dishes with pure water to make sure to get rid of any soap residue that could affect the taste of the food.ĭishwashing liquid can be a skin irritant and cause hand eczema. The reduced surface tension of dishwashing water, and increasing solubility of modern surfactant mixtures, allows the water to run off the dishes in a dish rack very quickly. Experience has proven a range of about 136 - 170 will gennerally be acceptable.Hand dishwashing detergents utilize surfactants to play the primary role in cleaning. It is used to predict the physical characteristics of the soap bar - the ideal being 160. The exact origin of the value is unclear but INS is derived from Iodine value and the SAP value hence INS - "Iodine ’n SAP" If the value is not in "Essentially Soap", it is estimated by subtracting the Iodine Value from the KOH SAP. McDaniel in his wonderful book " Essentially Soap". INS - A measure of the physical qualities of the soap based on the SAP and iodine value. Definition: number of grams of iodine that will react with the double bonds in 100 grams of fats or oils. A recipe with iodine values higher than 70 will tend to produce a somewhat soft bar of soap. Iodine - As a general rule, the lower the number, the harder the bar and the less the conditioning qualities and vice versa. Soap made with oils that do not contain Lauric, Myristic or Ricinoleic acids will produce a soap with just creamy lather. The higher Creamy numbers will tend to produce a creamy lather with lesser amounts of bubbles or foam. Usually, increasing Bubbly will decrease Creamy and vice versa. ![]() The higher Bubbly numbers will tend to produce a foamy, fluffy lather rather than a creamy lather with littler or no bubbles.Ĭreamy lather - This value indicates the stability and creaminess of the lather. A typical range of values would be 14 to 46. A range of 44 to 69 is satisfactory for this soap quality.īubbly lather - This refers to the soap’s ability to lather up and get bubbly. A soap’s emollients are left on the skin. A typical range for Cleansing would be 12 to 22.Ĭondition - Conditioning refers to the soap’s emollient content. However, when using large or very large percentages of coconut and palm kernel the strong cleansing can be compensated for by superfating with an oil or butter that has a high conditioning value. Generally speaking, keeping the total of coconut and palm kernel in your recipe to no more than 30-35% is considered the norm. Soap made with too much Lauric and/or Myristic Acid can irritate the skin by washing away not only the top dirty layer of oils, but also the protective layer of surface oils on the skin. Some soap molecules can have a very hungry oil grabbing end. When you rinse, the oil droplets with the attached soap molecules are washed away. To make this happen you need to mix up (scrub or rub) the soap and water on your skin. The water hungry ends are surrounded with water. When you wash your skin with soap and water, multiple chains will gather around a droplet of oil (which contains, for lack of a better word, dirt) with their oil-hungry ends attached to the oil droplet. ![]() ![]() One end of the chain attracts water, the other end attracts oil. A soap molecule is a chain of carbon atoms. A low Iodine value also contributes to hardness (see below).Ĭleansing - This refers to the soap's ability to grab on to oils. A range of 29 to 54 is satisfactory for this soap quality. Hardness - This refers to the hardness of the soap bar. As you gain experience, you will lean where you can color outside the lines so to speak. The ranges of numbers below represent typical values. ![]()
