The objective of this research was to determine the formulation of soap for carving
operations and study the satisfaction of developed carved-soap by carving person. There were 3
basic formulas of the soap e.g., olive oil formula (formula 1; 500 ml olive oil, 60 g sodium
hydroxide and 140 ml water), coconut oil formula (formula 2; 200 ml coconut oil, 34 g sodium
hydroxide and 80 ml water) and glycerin formula (formula 3; 200 g glycerin and 5 g sodium
hydroxide). The basic formula 3 showed the highest satisfaction scores from carving person
when compared with other formulas. The next experiment was to find the optimal temperature
for heating the mixtures in the range of 40-60oC. The results showed that the temperature of 45oC
was the best treatment for heating three types of soap mixtures. Moreover, the formula 3 soap
received the highest satisfaction scores ( X = 4.21-4.53) from carving person which had the good
appearance, exquisite styles, shape and proportion right. There was no crack, no visible of mold
growth and soap powder on the product after caving operations. The satisfaction of 52 carving
persons between the general soap and developed carved-soap for carving operations was studied
using 5-point rating scales. The satisfaction scores of softness, stickiness and aroma were
significant different (p<0.05) between two types of soap. However, the dryness/hardness,
silkiness, color, painting property and overall quality scores were not different. The suitable
shape of soap for carving operations was a round shape followed by square shape, oval shape and
heart shape, respectively.
