Reflection

We enjoyed alot doing this chemistry project. We learned alot of information about how acids, Bases & Salts are used in our daily life. Some of these products are even used by us personally, so we were surprised to find that some of these acids are actually present in our very own daily products.

We also learned team work through this. We learned how fun chemistry is while doing our research about the chemicals.

Chemical Formula

Sodium laureth sulfate - CH3(CH2)10CH2(OCH2CH2)nOSO3Na

Lauric acid - C12H24O2

Manganese sulfate - MnSO4

Benzoyl peroxide - (C6H5CO)2O2

Salicylic Acid - C7H6O3

Sodium Laureth Sufate


Sodium laureth sulfate, is a detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste etc.). Sodium laureth sulfate is an inexpensive and very effective foaming agent.

Manganese Sulfate


manganese might be helpful for those with osteoporosis and osteoarthritis as well as individuals with premenstrual syndrome (PMS). However, evidence substantiating these benefits is inconclusive.

Manganese is abundant in natural sources, especially in fruits and vegetables. Manganese foods include nuts, seeds, avocados, seaweeds, raisins, spinach, broccoli, beans, whole grains, egg yolks, peas, orange, spinach and other green leafy vegetables.

If you do not get enough manganese in your daily diet, you stand the risk of manganese deficiency. Deficiency in manganese leads to various health problems which may include bone malformation, eye and hearing problems, high cholesterol levels, hypertension, infertility, weakness, heart disorders, memory loss, muscle contraction, tremors, seizures and so on.

Benzoyl Per-Oxide




Benzoyl peroxide is used as an acne treatment, for improving flour, for bleaching hair and teeth, for polymerising polyester and many other uses.

Most benzoyl peroxide is used as a radical initiator to induce polymerizations.Other major applications include its antiseptic and bleaching properties.

Other common uses for benzoyl peroxide include dyeing hair, and as an active ingredient in teeth whitening systems. It is also used in the preparation of flour, and can be used as an initiator and catalyst for polyester thermoset resins (as an alternative to the much more hazardous methyl ethyl ketone peroxide).[citation needed]

Lauric Acid


Lauric acid a saturated fatty acid, is a white, powdery solid with a faint odor of bay oil or soap.

Lauric acid is the main acid in coconut oil and in palm kernel oil (not to be confused with palm oil),and is believed to have antimicrobial properties.It is also found in human milk, cow's milk, and goat's milk.

Current experiments have suggested that lauric acid could be a solution for teenage acne.
