The basic soap ingredients such as oil and alkaline as well as the equipments can be bought locally. The seaweeds can be gathered easily the coastal areas. Thus, the total cost for a single operations of the soap making is very minimal and affordable by the producers. The return of investment is 41% if price is P25.00/pc. and break even at P14.74/pc.

Results indicated that the formulated bath soap causes one of the ten (1/10) animals reacting with very slight erythema which detected within the first 30 minutes with reversible reaction during the succeeding periods of evaluation. The skin reaction was evaluated in 30 minutes, 24hours, 3days and 7 days for reactions of erythema and or edema. Table 7.
